+title: PII Redaction for Traces
+description: "Automatically redact sensitive data from crew and flow execution traces"
+icon: "lock"
+mode: "wide"
+---
+
+## Overview
+
+PII Redaction is a CrewAI AMP feature that automatically detects and masks Personally Identifiable Information (PII) in your crew and flow execution traces. This ensures sensitive data like credit card numbers, social security numbers, email addresses, and names are not exposed in your CrewAI AMP traces. You can also create custom recognizers to protect organization-specific data.
+
+
+<Info>
+  PII Redaction is available on the Enterprise plan.
+  Deployment must be version 1.8.0 or higher.
+</Info>
+
+
+<Frame>
+  ![PII Redaction Overview](/images/enterprise/pii_mask_recognizer_trace_example.png)
+</Frame>
+
+
+## Why PII Redaction Matters
+
+When running AI agents in production, sensitive information often flows through your crews:
+
+- Customer data from CRM integrations
+- Financial information from payment processors
+- Personal details from form submissions
+- Internal employee data
+
+Without proper redaction, this data appears in traces, making compliance with regulations like GDPR, HIPAA, and PCI-DSS challenging. PII Redaction solves this by automatically masking sensitive data before it's stored in traces.
+
+## How It Works
+
+1. **Detect** - Scan trace event data for known PII patterns
+2. **Classify** - Identify the type of sensitive data (credit card, SSN, email, etc.)
+3. **Mask/Redact** - Replace the sensitive data with masked values based on your configuration
+
+```
+Original: "Contact john.doe@company.com or call 555-123-4567"
+Redacted: "Contact <EMAIL_ADDRESS> or call <PHONE_NUMBER>"
+```
+
+## Enabling PII Redaction
+
+<Info>
+  You must be on the Enterprise plan and your deployment must be version 1.8.0 or higher to use this feature.
+</Info>
+
+<Steps>
+  <Step title="Navigate to Crew Settings">
+    In the CrewAI AMP dashboard, select your deployed crew and go to one of your deployments/automations, then navigate to **Settings** → **PII Protection**.
+  </Step>
+
+  <Step title="Enable PII Protection">
+    Toggle on **PII Redaction for Traces**. This will enable automatic scanning and redaction of trace data.
+
+    <Info>
+      You need to manually enable PII Redaction for each deployment.

+
+## Supported Entity Types
+
+CrewAI supports the following PII entity types, organized by category.
+
+### Global Entities
+
+| Entity | Description | Example |
+|--------|-------------|---------|
+| `CREDIT_CARD` | Credit/debit card numbers | "4111-1111-1111-1111" |
+| `CRYPTO` | Cryptocurrency wallet addresses | "bc1qxy2kgd..." |
+| `DATE_TIME` | Dates and times | "January 15, 2024" |
+| `EMAIL_ADDRESS` | Email addresses | "john@example.com" |
+| `IBAN_CODE` | International bank account numbers | "DE89 3704 0044 0532 0130 00" |
+| `IP_ADDRESS` | IPv4 and IPv6 addresses | "192.168.1.1" |
+| `LOCATION` | Geographic locations | "New York City" |
+| `MEDICAL_LICENSE` | Medical license numbers | "MD12345" |
+| `NRP` | Nationalities, religious, or political groups | - |
+| `PERSON` | Personal names | "John Doe" |
+| `PHONE_NUMBER` | Phone numbers in various formats | "+1 (555) 123-4567" |
+| `URL` | Web URLs | "https://example.com" |
+
+### US-Specific Entities
+
+| Entity | Description | Example |
+|--------|-------------|---------|
+| `US_BANK_NUMBER` | US Bank account numbers | "1234567890" |
+| `US_DRIVER_LICENSE` | US Driver's license numbers | "D1234567" |
+| `US_ITIN` | Individual Taxpayer ID | "900-70-0000" |
+| `US_PASSPORT` | US Passport numbers | "123456789" |
+| `US_SSN` | Social Security Numbers | "123-45-6789" |
+
+## Redaction Actions
+
+For each enabled entity, you can configure how the data is redacted:
+
+| Action | Description | Example Output |
+|--------|-------------|----------------|
+| `mask` | Replace with the entity type label | `<CREDIT_CARD>` |
+| `redact` | Completely remove the text | *(empty)* |
+
+## Custom Recognizers
+
+In addition to built-in entities, you can create **custom recognizers** to detect organization-specific PII patterns.
+
+<Frame>
+  ![Custom Recognizers](/images/enterprise/pii_mask_recognizer.png)
+</Frame>
+
+### Recognizer Types
+
+You have two options for custom recognizers:
+
+| Type | Best For | Example Use Case |
+|------|----------|------------------|
+| **Pattern-based (Regex)** | Structured data with predictable formats | Salary amounts, employee IDs, project codes |
+| **Deny-list** | Exact string matches | Company names, internal codenames, specific terms |
+
+### Creating a Custom Recognizer
+
+<Steps>
+  <Step title="Navigate to Custom Recognizers">
+    Go to your Organization **Settings** → **Organization** → **Add Recognizer**.
+  </Step>
+
+  <Step title="Configure the Recognizer">
+    <Frame>
+      ![Configure Recognizer](/images/enterprise/pii_mask_recognizer_create.png)
+    </Frame>
+
+    Configure the following fields:
+    - **Name**: A descriptive name for the recognizer
+    - **Entity Type**: The entity label that will appear in redacted output (e.g., `EMPLOYEE_ID`, `SALARY`)
+    - **Type**: Choose between Regex Pattern or Deny List
+    - **Pattern/Values**: Regex pattern or list of strings to match
+    - **Confidence Threshold**: Minimum score (0.0-1.0) required for a match to trigger redaction. Higher values (e.g., 0.8) reduce false positives but may miss some matches. Lower values (e.g., 0.5) catch more matches but may over-redact. Default is 0.8.
+    - **Context Words** (optional): Words that increase detection confidence when found nearby
+  </Step>
+
+  <Step title="Save">
+    Save the recognizer. It will be available to enable on your deployments.
+  </Step>
+</Steps>
+
+### Understanding Entity Types
+
+The **Entity Type** determines how matched content appears in redacted traces:
+
+```
+Entity Type: SALARY
+Pattern: salary:\s*\$\s*\d+
+Input: "Employee salary: $50,000"
+Output: "Employee <SALARY>"
+```
+
+### Using Context Words
+
+Context words improve accuracy by increasing confidence when specific terms appear near the matched pattern:
+
+```
+Context Words: "project", "code", "internal"
+Entity Type: PROJECT_CODE
+Pattern: PRJ-\d{4}
+```
+
+When "project" or "code" appears near "PRJ-1234", the recognizer has higher confidence it's a true match, reducing false positives.
+
+
+## Viewing Redacted Traces
+
+Once PII redaction is enabled, your traces will show redacted values in place of sensitive data:
+
+```
+Task Output: "Customer <PERSON> placed order #12345.
+Contact email: <EMAIL_ADDRESS>, phone: <PHONE_NUMBER>.
+Payment processed for card ending in <CREDIT_CARD>."
+```
+
+Redacted values are clearly marked with angle brackets and the entity type label (e.g., `<EMAIL_ADDRESS>`), making it easy to understand what data was protected while still allowing you to debug and monitor crew behavior.
+
+
+
+## Best Practices
+
+### Performance Considerations
+
+<Steps>
+  <Step title="Enable Only Needed Entities">
+    Each enabled entity adds processing overhead. Only enable entities relevant to your data.
+  </Step>
+
+  <Step title="Use Specific Patterns">
+    For custom recognizers, use specific patterns to reduce false positives and improve performance. Regex patterns are best when identifying specific patterns in the traces such as salary, employee id, project code, etc. Deny-list recognizers are best when identifying exact strings in the traces such as company names, internal codenames, etc.
+  </Step>
+
+  <Step title="Leverage Context Words">
+    Context words improve accuracy by only triggering detection when surrounding text matches.
+  </Step>
+</Steps>
+
+## Troubleshooting
+
+<Accordion title="PII Not Being Redacted">
+  **Possible Causes:**
+  - Entity type not enabled in configuration
+  - Pattern doesn't match the data format
+  - Custom recognizer has syntax errors
+
+  **Solutions:**
+  - Verify entity is enabled in Settings → Security
+  - Test regex patterns with sample data
+  - Check logs for configuration errors
+</Accordion>
+
+<Accordion title="Too Much Data Being Redacted">
+  **Possible Causes:**
+  - Overly broad entity types enabled (e.g., `DATE_TIME` catches dates everywhere)
+  - Custom recognizer patterns are too general
+
+  **Solutions:**
+  - Disable entities that cause false positives
+  - Make custom patterns more specific
+  - Add context words to improve accuracy
+</Accordion>
+
+<Accordion title="Performance Issues">
+  **Possible Causes:**
+  - Too many entities enabled
+  - NLP-based entities (`PERSON`, `LOCATION`, `NRP`) are computationally expensive as they use machine learning models
+
+  **Solutions:**
+  - Only enable entities you actually need
+  - Consider using pattern-based alternatives where possible
+  - Monitor trace processing times in the dashboard

+
+## Practical Example: Salary Pattern Matching
+
+This example demonstrates how to create a custom recognizer to detect and mask salary information in your traces.
+
+### Use Case
+
+Your crew processes employee or financial data that includes salary information in formats like:
+- `salary: $50,000`
+- `salary: $125,000.00`
+- `salary:$1,500.50`
+
+You want to automatically mask these values to protect sensitive compensation data.
+
+### Configuration
+
+<Frame>
+  ![Salary Recognizer Configuration](/images/enterprise/pii_mask_custom_recognizer_salary.png)
+</Frame>
+
+| Field | Value |
+|-------|-------|
+| **Name** | `SALARY` |
+| **Entity Type** | `SALARY` |
+| **Type** | Regex Pattern |
+| **Regex Pattern** | `salary:\s*\$\s*\d{1,3}(,\d{3})*(\.\d{2})?` |
+| **Action** | Mask |
+| **Confidence Threshold** | `0.8` |
+| **Context Words** | `salary, compensation, pay, wage, income` |
+
+### Regex Pattern Breakdown
+
+| Pattern Component | Meaning |
+|-------------------|---------|
+| `salary:` | Matches the literal text "salary:" |
+| `\s*` | Matches zero or more whitespace characters |
+| `\$` | Matches the dollar sign (escaped) |
+| `\s*` | Matches zero or more whitespace characters after $ |
+| `\d{1,3}` | Matches 1-3 digits (e.g., "1", "50", "125") |
+| `(,\d{3})*` | Matches comma-separated thousands (e.g., ",000", ",500,000") |
+| `(\.\d{2})?` | Optionally matches cents (e.g., ".00", ".50") |
+
+### Example Results
+
+```
+Original: "Employee record shows salary: $125,000.00 annually"
+Redacted: "Employee record shows <SALARY> annually"
+
+Original: "Base salary:$50,000 with bonus potential"
+Redacted: "Base <SALARY> with bonus potential"
+```
+
+<Tip>
+  Adding context words like "salary", "compensation", "pay", "wage", and "income" helps increase detection confidence when these terms appear near the matched pattern, reducing false positives.
+</Tip>
+
+### Enable the Recognizer for Your Deployments
+
+<Warning>
+  Creating a custom recognizer at the organization level does not automatically enable it for your deployments. You must manually enable each recognizer for every deployment where you want it applied.
+</Warning>
+
+After creating your custom recognizer, enable it for each deployment:

 ## A2A Agent Delegation
 
-CrewAI supports the Agent-to-Agent (A2A) protocol, allowing agents to delegate tasks to remote specialized agents. The agent's LLM automatically decides whether to handle a task directly or delegate to an A2A agent based on the task requirements.
-
-<Note>
-  A2A delegation requires the `a2a-sdk` package. Install with: `uv add 'crewai[a2a]'` or `pip install 'crewai[a2a]'`
-</Note>
+CrewAI treats [A2A protocol](https://a2a-protocol.org/latest/) as a first-class delegation primitive, enabling agents to delegate tasks, request information, and collaborate with remote agents, as well as act as A2A-compliant server agents.
+In client mode, agents autonomously choose between local execution and remote delegation based on task requirements.
 
 ## How It Works
 
 When an agent is configured with A2A capabilities:
 
-1. The LLM analyzes each task
+1. The Agent analyzes each task
 2. It decides to either:
    - Handle the task directly using its own capabilities
    - Delegate to a remote A2A agent for specialized handling
 3. If delegating, the agent communicates with the remote A2A agent through the protocol
 4. Results are returned to the CrewAI workflow
 
+<Note>
+  A2A delegation requires the `a2a-sdk` package. Install with: `uv add 'crewai[a2a]'` or `pip install 'crewai[a2a]'`

+
 ## Basic Configuration
 
+<Warning>
+  `crewai.a2a.config.A2AConfig` is deprecated and will be removed in v2.0.0. Use `A2AClientConfig` for connecting to remote agents and/or `A2AServerConfig` for exposing agents as servers.

+title: Galileo
+description: Galileo integration for CrewAI tracing and evaluation
+icon: telescope
+mode: "wide"
+---
+
+## Overview
+
+This guide demonstrates how to integrate **Galileo** with **CrewAI**
+for comprehensive tracing and Evaluation Engineering.
+By the end of this guide, you will be able to trace your CrewAI agents,
+monitor their performance, and evaluate their behaviour with
+Galileo's powerful observability platform.
+
+> **What is Galileo?** [Galileo](https://galileo.ai) is AI evaluation and observability
+platform that delivers end-to-end tracing, evaluation,
+and monitoring for AI applications. It enables teams to capture ground truth,
+create robust guardrails, and run systematic experiments with
+built-in experiment tracking and performance analytics—ensuring reliability,
+transparency, and continuous improvement across the AI lifecycle.
+
+## Getting started
+
+This tutorial follows the [CrewAI quickstart](/en/quickstart) and shows how to add
+Galileo's [CrewAIEventListener](https://v2docs.galileo.ai/sdk-api/python/reference/handlers/crewai/handler),
+an event handler.
+For more information, see Galileo’s
+[Add Galileo to a CrewAI Application](https://v2docs.galileo.ai/how-to-guides/third-party-integrations/add-galileo-to-crewai/add-galileo-to-crewai)
+how-to guide.
+
+> **Note** This tutorial assumes you have completed the [CrewAI quickstart](/en/quickstart).
+If you want a completed comprehensive example, see the Galileo
+[CrewAI sdk-example repo](https://github.com/rungalileo/sdk-examples/tree/main/python/agent/crew-ai).
+
+### Step 1: Install dependencies
+
+Install the required dependencies for your app.
+Create a virtual environment using your preferred method,
+then install dependencies inside that environment using your
+preferred tool:
+
+```bash
+uv add galileo 
+```
+
+### Step 2: Add to the .env file from the [CrewAI quickstart](/en/quickstart)
+
+```bash
+# Your Galileo API key
+GALILEO_API_KEY="your-galileo-api-key"
+
+# Your Galileo project name
+GALILEO_PROJECT="your-galileo-project-name"
+
+# The name of the Log stream you want to use for logging
+GALILEO_LOG_STREAM="your-galileo-log-stream "
+```
+
+### Step 3: Add the Galileo event listener
+
+To enable logging with Galileo, you need to create an instance of the `CrewAIEventListener`.
+Import the Galileo CrewAI handler package by
+adding the following code at the top of your main.py file:
+
+```python
+from galileo.handlers.crewai.handler import CrewAIEventListener
+```
+
+At the start of your run function, create the event listener:
+
+```python
+def run():
+    # Create the event listener
+    CrewAIEventListener()
+    # The rest of your existing code goes here
+```
+
+When you create the listener instance, it is automatically
+registered with CrewAI.
+
+### Step 4: Run your crew
+
+Run your crew with the CrewAI CLI:
+
+```bash
+crewai run
+```
+
+### Step 5: View the traces in Galileo
+
+Once your crew has finished, the traces will be flushed and appear in Galileo.
+
+![Galileo trace view](/images/galileo-trace-veiw.png)
+  
+## Understanding the Galileo Integration
+
+Galileo integrates with CrewAI by registering an event listener
+that captures Crew execution events (e.g., agent actions, tool calls, model responses)
+and forwards them to Galileo for observability and evaluation.
+
+### Understanding the event listener
+
+Creating a `CrewAIEventListener()` instance is all that’s
+required to enable Galileo for a CrewAI run. When instantiated, the listener:
+
+- Automatically registers itself with CrewAI
+- Reads Galileo configuration from environment variables
+- Logs all run data to the Galileo project and log stream specified by
+  `GALILEO_PROJECT` and `GALILEO_LOG_STREAM`
+
+No additional configuration or code changes are required.
+All data from this run is logged to the Galileo project and
+log stream specified by your environment configuration
+(for example, GALILEO_PROJECT and GALILEO_LOG_STREAM).

+title: 트레이스용 PII 삭제
+description: "크루 및 플로우 실행 트레이스에서 민감한 데이터를 자동으로 삭제합니다"
+icon: "lock"
+mode: "wide"
+---
+
+## 개요
+
+PII 삭제는 크루 및 플로우 실행 트레이스에서 개인 식별 정보(PII)를 자동으로 감지하고 마스킹하는 CrewAI AMP 기능입니다. 이를 통해 신용카드 번호, 주민등록번호, 이메일 주소, 이름과 같은 민감한 데이터가 CrewAI AMP 트레이스에 노출되지 않도록 보장합니다. 또한 조직별 데이터를 보호하기 위해 커스텀 인식기를 생성할 수 있습니다.
+
+
+<Info>
+  PII 삭제는 Enterprise 플랜에서 사용 가능합니다.
+  배포 버전은 1.8.0 이상이어야 합니다.
+</Info>
+
+
+<Frame>

+</Frame>
+
+
+## PII 삭제가 중요한 이유
+
+프로덕션 환경에서 AI 에이전트를 실행할 때, 민감한 정보가 종종 크루를 통해 흐릅니다:
+
+- CRM 통합의 고객 데이터
+- 결제 처리업체의 금융 정보
+- 양식 제출의 개인 정보
+- 내부 직원 데이터
+
+적절한 삭제 없이는 이 데이터가 트레이스에 나타나, GDPR, HIPAA, PCI-DSS와 같은 규정 준수가 어려워집니다. PII 삭제는 트레이스에 저장되기 전에 민감한 데이터를 자동으로 마스킹하여 이 문제를 해결합니다.
+
+## 작동 방식
+
+1. **감지** - 알려진 PII 패턴에 대해 트레이스 이벤트 데이터를 스캔
+2. **분류** - 민감한 데이터 유형 식별 (신용카드, SSN, 이메일 등)
+3. **마스킹/삭제** - 구성에 따라 민감한 데이터를 마스킹된 값으로 대체
+

+## 지원되는 엔티티 유형
+
+CrewAI는 카테고리별로 구성된 다음 PII 엔티티 유형을 지원합니다.
+
+### 글로벌 엔티티
+
+| 엔티티 | 설명 | 예시 |
+|--------|------|------|
+| `CREDIT_CARD` | 신용/직불 카드 번호 | "4111-1111-1111-1111" |
+| `CRYPTO` | 암호화폐 지갑 주소 | "bc1qxy2kgd..." |
+| `DATE_TIME` | 날짜 및 시간 | "2024년 1월 15일" |
+| `EMAIL_ADDRESS` | 이메일 주소 | "john@example.com" |
+| `IBAN_CODE` | 국제 은행 계좌 번호 | "DE89 3704 0044 0532 0130 00" |
+| `IP_ADDRESS` | IPv4 및 IPv6 주소 | "192.168.1.1" |
+| `LOCATION` | 지리적 위치 | "뉴욕시" |
+| `MEDICAL_LICENSE` | 의료 면허 번호 | "MD12345" |
+| `NRP` | 국적, 종교 또는 정치 그룹 | - |
+| `PERSON` | 개인 이름 | "홍길동" |
+| `PHONE_NUMBER` | 다양한 형식의 전화번호 | "+82 (10) 1234-5678" |
+| `URL` | 웹 URL | "https://example.com" |
+
+### 미국 특정 엔티티
+
+| 엔티티 | 설명 | 예시 |
+|--------|------|------|
+| `US_BANK_NUMBER` | 미국 은행 계좌 번호 | "1234567890" |
+| `US_DRIVER_LICENSE` | 미국 운전면허 번호 | "D1234567" |
+| `US_ITIN` | 개인 납세자 번호 | "900-70-0000" |
+| `US_PASSPORT` | 미국 여권 번호 | "123456789" |
+| `US_SSN` | 사회보장번호 | "123-45-6789" |
+
+## 삭제 작업
+
+활성화된 각 엔티티에 대해 데이터가 삭제되는 방식을 구성할 수 있습니다:
+
+| 작업 | 설명 | 출력 예시 |
+|------|------|----------|
+| `mask` | 엔티티 유형 레이블로 대체 | `<CREDIT_CARD>` |
+| `redact` | 텍스트를 완전히 제거 | *(비어있음)* |
+
+## 커스텀 인식기
+
+기본 제공 엔티티 외에도 조직별 PII 패턴을 감지하기 위한 **커스텀 인식기**를 생성할 수 있습니다.
+
+<Frame>
+  ![커스텀 인식기](/images/enterprise/pii_mask_recognizer.png)
+</Frame>
+
+### 인식기 유형
+
+커스텀 인식기에는 두 가지 옵션이 있습니다:
+
+| 유형 | 적합한 용도 | 사용 사례 예시 |
+|------|------------|---------------|
+| **패턴 기반 (Regex)** | 예측 가능한 형식의 구조화된 데이터 | 급여 금액, 직원 ID, 프로젝트 코드 |
+| **거부 목록** | 정확한 문자열 매칭 | 회사명, 내부 코드명, 특정 용어 |
+
+### 커스텀 인식기 생성
+
+<Steps>
+  <Step title="커스텀 인식기로 이동">
+    조직 **Settings** → **Organization** → **Add Recognizer**로 이동합니다.
+  </Step>
+
+  <Step title="인식기 구성">
+    <Frame>
+      ![인식기 구성](/images/enterprise/pii_mask_recognizer_create.png)
+    </Frame>
+
+    다음 필드를 구성합니다:
+    - **Name**: 인식기의 설명적 이름
+    - **Entity Type**: 삭제된 출력에 나타날 엔티티 레이블 (예: `EMPLOYEE_ID`, `SALARY`)
+    - **Type**: Regex 패턴 또는 거부 목록 중 선택
+    - **Pattern/Values**: 매칭할 Regex 패턴 또는 문자열 목록
+    - **Confidence Threshold**: 삭제를 트리거하는 데 필요한 최소 점수 (0.0-1.0). 높은 값 (예: 0.8)은 거짓 양성을 줄이지만 일부 매치를 놓칠 수 있습니다. 낮은 값 (예: 0.5)은 더 많은 매치를 잡지만 과도하게 삭제할 수 있습니다. 기본값은 0.8입니다.
+    - **Context Words** (선택사항): 근처에서 발견될 때 감지 신뢰도를 높이는 단어
+  </Step>
+
+  <Step title="저장">
+    인식기를 저장합니다. 배포에서 활성화할 수 있게 됩니다.
+  </Step>
+</Steps>
+
+### 엔티티 유형 이해하기
+
+**Entity Type**은 매칭된 콘텐츠가 삭제된 트레이스에 어떻게 나타나는지 결정합니다:
+
+```
+Entity Type: SALARY
+Pattern: salary:\s*\$\s*\d+
+입력: "직원 급여: $50,000"
+출력: "직원 <SALARY>"
+```
+
+### 컨텍스트 단어 사용
+
+컨텍스트 단어는 매칭된 패턴 근처에 특정 용어가 나타날 때 신뢰도를 높여 정확도를 향상시킵니다:
+
+```
+Context Words: "project", "code", "internal"
+Entity Type: PROJECT_CODE
+Pattern: PRJ-\d{4}
+```
+
+"project" 또는 "code"가 "PRJ-1234" 근처에 나타나면, 인식기는 그것이 진정한 매치라는 확신이 높아져 거짓 양성을 줄입니다.
+
+
+## 삭제된 트레이스 보기
+
+PII 삭제가 활성화되면, 트레이스에서 민감한 데이터 대신 삭제된 값이 표시됩니다:
+
+```
+Task Output: "고객 <PERSON>이 주문 #12345를 했습니다.
+연락처 이메일: <EMAIL_ADDRESS>, 전화: <PHONE_NUMBER>.
+<CREDIT_CARD>로 끝나는 카드로 결제가 처리되었습니다."
+```
+
+삭제된 값은 꺾쇠 괄호와 엔티티 유형 레이블 (예: `<EMAIL_ADDRESS>`)로 명확하게 표시되어, 어떤 데이터가 보호되었는지 쉽게 이해할 수 있으면서도 크루 동작을 디버그하고 모니터링할 수 있습니다.
+
+
+
+## 모범 사례
+
+### 성능 고려사항
+
+<Steps>
+  <Step title="필요한 엔티티만 활성화">
+    활성화된 각 엔티티는 처리 오버헤드를 추가합니다. 데이터와 관련된 엔티티만 활성화하세요.
+  </Step>
+
+  <Step title="구체적인 패턴 사용">
+    커스텀 인식기의 경우 거짓 양성을 줄이고 성능을 향상시키기 위해 구체적인 패턴을 사용하세요. Regex 패턴은 급여, 직원 ID, 프로젝트 코드 등 특정 패턴을 식별할 때 가장 적합합니다. 거부 목록 인식기는 회사명, 내부 코드명 등 정확한 문자열을 식별할 때 가장 적합합니다.
+  </Step>
+
+  <Step title="컨텍스트 단어 활용">
+    컨텍스트 단어는 주변 텍스트가 매칭될 때만 감지를 트리거하여 정확도를 향상시킵니다.
+  </Step>
+</Steps>
+
+## 문제 해결
+
+<Accordion title="PII가 삭제되지 않음">
+  **가능한 원인:**
+  - 구성에서 엔티티 유형이 활성화되지 않음
+  - 패턴이 데이터 형식과 매치되지 않음
+  - 커스텀 인식기에 구문 오류가 있음
+
+  **해결책:**
+  - Settings → Security에서 엔티티가 활성화되어 있는지 확인
+  - 샘플 데이터로 regex 패턴 테스트
+  - 구성 오류에 대한 로그 확인
+</Accordion>
+
+<Accordion title="너무 많은 데이터가 삭제됨">
+  **가능한 원인:**
+  - 너무 광범위한 엔티티 유형이 활성화됨 (예: `DATE_TIME`이 모든 곳의 날짜를 잡음)
+  - 커스텀 인식기 패턴이 너무 일반적임
+
+  **해결책:**
+  - 거짓 양성을 유발하는 엔티티 비활성화
+  - 커스텀 패턴을 더 구체적으로 만들기
+  - 정확도 향상을 위해 컨텍스트 단어 추가
+</Accordion>
+
+<Accordion title="성능 문제">
+  **가능한 원인:**
+  - 너무 많은 엔티티가 활성화됨
+  - NLP 기반 엔티티 (`PERSON`, `LOCATION`, `NRP`)는 머신러닝 모델을 사용하므로 계산 비용이 높음
+
+  **해결책:**
+  - 실제로 필요한 엔티티만 활성화
+  - 가능한 경우 패턴 기반 대안 고려
+  - 대시보드에서 트레이스 처리 시간 모니터링

+
+## 실제 예시: 급여 패턴 매칭
+
+이 예시는 트레이스에서 급여 정보를 감지하고 마스킹하는 커스텀 인식기를 생성하는 방법을 보여줍니다.
+
+### 사용 사례
+
+크루가 다음과 같은 형식의 급여 정보가 포함된 직원 또는 재무 데이터를 처리합니다:
+- `salary: $50,000`
+- `salary: $125,000.00`
+- `salary:$1,500.50`
+
+민감한 보상 데이터를 보호하기 위해 이러한 값을 자동으로 마스킹하려고 합니다.
+
+### 구성
+
+<Frame>
+  ![급여 인식기 구성](/images/enterprise/pii_mask_custom_recognizer_salary.png)
+</Frame>
+
+| 필드 | 값 |
+|------|-----|
+| **Name** | `SALARY` |
+| **Entity Type** | `SALARY` |
+| **Type** | Regex Pattern |
+| **Regex Pattern** | `salary:\s*\$\s*\d{1,3}(,\d{3})*(\.\d{2})?` |
+| **Action** | Mask |
+| **Confidence Threshold** | `0.8` |
+| **Context Words** | `salary, compensation, pay, wage, income` |
+
+### Regex 패턴 분석
+
+| 패턴 구성요소 | 의미 |
+|--------------|------|
+| `salary:` | 리터럴 텍스트 "salary:" 매치 |
+| `\s*` | 0개 이상의 공백 문자 매치 |
+| `\$` | 달러 기호 매치 (이스케이프) |
+| `\s*` | $ 뒤의 0개 이상의 공백 문자 매치 |
+| `\d{1,3}` | 1-3자리 숫자 매치 (예: "1", "50", "125") |
+| `(,\d{3})*` | 쉼표로 구분된 천 단위 매치 (예: ",000", ",500,000") |
+| `(\.\d{2})?` | 선택적으로 센트 매치 (예: ".00", ".50") |

+
+### 1단계: 종속성 설치
+
+앱에 필요한 종속성을 설치합니다.
+원하는 방법으로 가상 환경을 생성하고,
+그런 다음 다음을 사용하여 해당 환경 내에 종속성을 설치하십시오.
+선호하는 도구:
+
+```bash
+uv add galileo 
+```
+
+### 2단계: [CrewAI 빠른 시작](/ko/quickstart.mdx)에서 .env 파일에 추가
+
+```bash
+# Your Galileo API key
+GALILEO_API_KEY="your-galileo-api-key"
+
+# Your Galileo project name
+GALILEO_PROJECT="your-galileo-project-name"
+
+# The name of the Log stream you want to use for logging
+GALILEO_LOG_STREAM="your-galileo-log-stream "
+```
+
+### 3단계: Galileo 이벤트 리스너 추가
+
+Galileo로 로깅을 활성화하려면 `CrewAIEventListener`의 인스턴스를 생성해야 합니다.
+다음을 통해 Galileo CrewAI 핸들러 패키지를 가져옵니다.
+main.py 파일 상단에 다음 코드를 추가하세요.
+
+```python
+from galileo.handlers.crewai.handler import CrewAIEventListener
+```
+
+실행 함수 시작 시 이벤트 리스너를 생성합니다.
+
+```python
+def run():
+    # Create the event listener
+    CrewAIEventListener()
+    # The rest of your existing code goes here
+```
+
+리스너 인스턴스를 생성하면 자동으로
+CrewAI에 등록되었습니다.
+
+### 4단계: Crew Agent 실행
+
+CrewAI CLI를 사용하여 Crew Agent를 실행하세요.
+
+```bash
+crewai run
+```
+
+### 5단계: Galileo에서 추적 보기
+
+승무원 에이전트가 완료되면 흔적이 플러시되어 Galileo에 나타납니다.

+title: Redação de PII para Traces
+description: "Redija automaticamente dados sensíveis de traces de execução de crews e flows"
+icon: "lock"
+mode: "wide"
+---
+
+## Visão Geral
+
+A Redação de PII é um recurso do CrewAI AMP que detecta e mascara automaticamente Informações de Identificação Pessoal (PII) nos traces de execução de crews e flows. Isso garante que dados sensíveis como números de cartão de crédito, CPF, endereços de e-mail e nomes não sejam expostos nos traces do CrewAI AMP. Você também pode criar reconhecedores personalizados para proteger dados específicos da sua organização.
+
+
+<Info>
+  A Redação de PII está disponível no plano Enterprise.
+  A implantação deve ser versão 1.8.0 ou superior.
+</Info>
+
+
+<Frame>
+  ![Visão Geral da Redação de PII](/images/enterprise/pii_mask_recognizer_trace_example.png)
+</Frame>
+
+
+## Por Que a Redação de PII é Importante
+
+Ao executar agentes de IA em produção, informações sensíveis frequentemente fluem através das suas crews:
+
+- Dados de clientes de integrações CRM
+- Informações financeiras de processadores de pagamento
+- Detalhes pessoais de envios de formulários
+- Dados internos de funcionários
+
+Sem a redação adequada, esses dados aparecem nos traces, tornando a conformidade com regulamentações como LGPD, HIPAA e PCI-DSS desafiadora. A Redação de PII resolve isso mascarando automaticamente dados sensíveis antes de serem armazenados nos traces.
+
+## Como Funciona
+
+1. **Detectar** - Escanear dados de eventos de trace para padrões de PII conhecidos
+2. **Classificar** - Identificar o tipo de dado sensível (cartão de crédito, CPF, e-mail, etc.)
+3. **Mascarar/Redigir** - Substituir os dados sensíveis por valores mascarados com base na sua configuração

+Redigido: "Entre em contato com <EMAIL_ADDRESS> ou ligue para <PHONE_NUMBER>"
+```
+
+## Habilitando a Redação de PII
+
+<Info>
+  Você deve estar no plano Enterprise e sua implantação deve ser versão 1.8.0 ou superior para usar este recurso.

+<Steps>
+  <Step title="Navegue até Configurações da Crew">
+    No painel do CrewAI AMP, selecione sua crew implantada e vá para uma de suas implantações/automações, depois navegue até **Settings** → **PII Protection**.
+  </Step>
+
+  <Step title="Habilitar Proteção PII">
+    Ative **PII Redaction for Traces**. Isso habilitará a varredura automática e redação de dados de trace.

+
+    Configure os seguintes campos:
+    - **Name**: Um nome descritivo para o reconhecedor
+    - **Entity Type**: O rótulo da entidade que aparecerá na saída redigida (ex.: `EMPLOYEE_ID`, `SALARY`)
+    - **Type**: Escolha entre Padrão Regex ou Lista de Negação
+    - **Pattern/Values**: Padrão regex ou lista de strings para corresponder
+    - **Confidence Threshold**: Pontuação mínima (0.0-1.0) necessária para uma correspondência acionar a redação. Valores mais altos (ex.: 0.8) reduzem falsos positivos, mas podem perder algumas correspondências. Valores mais baixos (ex.: 0.5) capturam mais correspondências, mas podem redigir em excesso. O padrão é 0.8.

+  </Step>
+
+  <Step title="Salvar">
+    Salve o reconhecedor. Ele estará disponível para habilitar em suas implantações.
+  </Step>
+</Steps>
+
+### Entendendo os Tipos de Entidade
+
+O **Entity Type** determina como o conteúdo correspondido aparece nos traces redigidos:
+
+```
+Entity Type: SALARY
+Pattern: salary:\s*\$\s*\d+
+Entrada: "Salário do funcionário: $50,000"
+Saída: "Salário do funcionário <SALARY>"
+```
+
+### Usando Palavras de Contexto
+
+Palavras de contexto melhoram a precisão aumentando a confiança quando termos específicos aparecem próximos ao padrão correspondido:
+
+```
+Context Words: "project", "code", "internal"
+Entity Type: PROJECT_CODE
+Pattern: PRJ-\d{4}
+```
+
+Quando "project" ou "code" aparece próximo a "PRJ-1234", o reconhecedor tem maior confiança de que é uma correspondência verdadeira, reduzindo falsos positivos.
+
+
+## Visualizando Traces Redigidos
+
+Uma vez que a redação de PII está habilitada, seus traces mostrarão valores redigidos no lugar de dados sensíveis:
+
+```
+Task Output: "Cliente <PERSON> fez o pedido #12345.
+E-mail de contato: <EMAIL_ADDRESS>, telefone: <PHONE_NUMBER>.
+Pagamento processado para cartão terminando em <CREDIT_CARD>."
+```
+
+Os valores redigidos são claramente marcados com colchetes angulares e o rótulo do tipo de entidade (ex.: `<EMAIL_ADDRESS>`), facilitando entender quais dados foram protegidos enquanto ainda permite depurar e monitorar o comportamento da crew.
+
+
+
+## Melhores Práticas
+
+### Considerações de Desempenho
+
+<Steps>
+  <Step title="Habilite Apenas Entidades Necessárias">
+    Cada entidade habilitada adiciona sobrecarga de processamento. Habilite apenas entidades relevantes para seus dados.
+  </Step>
+
+  <Step title="Use Padrões Específicos">
+    Para reconhecedores personalizados, use padrões específicos para reduzir falsos positivos e melhorar o desempenho. Padrões regex são melhores para identificar padrões específicos nos traces como salário, ID de funcionário, código de projeto, etc. Reconhecedores de lista de negação são melhores para identificar strings exatas nos traces como nomes de empresas, codinomes internos, etc.
+  </Step>
+
+  <Step title="Aproveite Palavras de Contexto">
+    Palavras de contexto melhoram a precisão acionando a detecção apenas quando o texto circundante corresponde.
+  </Step>
+</Steps>
+
+## Solução de Problemas
+
+<Accordion title="PII Não Está Sendo Redigido">
+  **Possíveis Causas:**
+  - Tipo de entidade não habilitado na configuração
+  - Padrão não corresponde ao formato dos dados
+  - Reconhecedor personalizado tem erros de sintaxe
+
+  **Soluções:**
+  - Verifique se a entidade está habilitada em Settings → Security
+  - Teste padrões regex com dados de amostra
+  - Verifique logs para erros de configuração
+</Accordion>
+
+<Accordion title="Muitos Dados Estão Sendo Redigidos">
+  **Possíveis Causas:**
+  - Tipos de entidade muito amplos habilitados (ex.: `DATE_TIME` captura datas em todos os lugares)
+  - Padrões de reconhecedor personalizado são muito gerais
+
+  **Soluções:**
+  - Desabilite entidades que causam falsos positivos
+  - Torne padrões personalizados mais específicos
+  - Adicione palavras de contexto para melhorar a precisão
+</Accordion>
+
+<Accordion title="Problemas de Desempenho">
+  **Possíveis Causas:**
+  - Muitas entidades habilitadas
+  - Entidades baseadas em NLP (`PERSON`, `LOCATION`, `NRP`) são computacionalmente caras pois usam modelos de machine learning

+
+## Exemplo Prático: Correspondência de Padrão de Salário
+
+Este exemplo demonstra como criar um reconhecedor personalizado para detectar e mascarar informações de salário em seus traces.
+
+### Caso de Uso
+
+Sua crew processa dados de funcionários ou financeiros que incluem informações de salário em formatos como:
+- `salary: $50,000`
+- `salary: $125,000.00`
+- `salary:$1,500.50`
+
+Você deseja mascarar automaticamente esses valores para proteger dados sensíveis de remuneração.
+
+### Configuração
+
+<Frame>
+  ![Configuração do Reconhecedor de Salário](/images/enterprise/pii_mask_custom_recognizer_salary.png)
+</Frame>
+
+| Campo | Valor |
+|-------|-------|
+| **Name** | `SALARY` |
+| **Entity Type** | `SALARY` |
+| **Type** | Regex Pattern |
+| **Regex Pattern** | `salary:\s*\$\s*\d{1,3}(,\d{3})*(\.\d{2})?` |
+| **Action** | Mask |
+| **Confidence Threshold** | `0.8` |
+| **Context Words** | `salary, compensation, pay, wage, income` |
+
+### Análise do Padrão Regex
+
+| Componente do Padrão | Significado |
+|----------------------|-------------|
+| `salary:` | Corresponde ao texto literal "salary:" |
+| `\s*` | Corresponde a zero ou mais caracteres de espaço em branco |
+| `\$` | Corresponde ao sinal de dólar (escapado) |
+| `\s*` | Corresponde a zero ou mais caracteres de espaço em branco após $ |
+| `\d{1,3}` | Corresponde a 1-3 dígitos (ex.: "1", "50", "125") |
+| `(,\d{3})*` | Corresponde a milhares separados por vírgula (ex.: ",000", ",500,000") |
+| `(\.\d{2})?` | Opcionalmente corresponde a centavos (ex.: ".00", ".50") |
+
+### Resultados de Exemplo
+
+```
+Original: "Registro do funcionário mostra salary: $125,000.00 anualmente"
+Redigido: "Registro do funcionário mostra <SALARY> anualmente"
+
+Original: "Salário base salary:$50,000 com potencial de bônus"
+Redigido: "Salário base <SALARY> com potencial de bônus"
+```
+
+<Tip>
+  Adicionar palavras de contexto como "salary", "compensation", "pay", "wage" e "income" ajuda a aumentar a confiança de detecção quando esses termos aparecem próximos ao padrão correspondido, reduzindo falsos positivos.

+title: Galileo Galileu
+description: Integração Galileo para rastreamento e avaliação CrewAI
+icon: telescope
+mode: "wide"
+---
+
+## Visão geral
+
+Este guia demonstra como integrar o **Galileo**com o **CrewAI**
+para rastreamento abrangente e engenharia de avaliação.
+Ao final deste guia, você será capaz de rastrear seus agentes CrewAI,
+monitorar seu desempenho e avaliar seu comportamento com
+A poderosa plataforma de observabilidade do Galileo.
+
+> **O que é Galileo?**[Galileo](https://galileo.ai/) é avaliação e observabilidade de IA
+plataforma que oferece rastreamento, avaliação e
+e monitoramento de aplicações de IA. Ele permite que as equipes capturem a verdade,
+criar grades de proteção robustas e realizar experimentos sistemáticos com
+rastreamento de experimentos integrado e análise de desempenho -garantindo confiabilidade,
+transparência e melhoria contínua em todo o ciclo de vida da IA.
+
+## Primeiros passos
+
+Este tutorial segue o [CrewAI Quickstart](pt-BR/quickstart) e mostra como adicionar
+[CrewAIEventListener] do Galileo(https://v2docs.galileo.ai/sdk-api/python/reference/handlers/crewai/handler),
+um manipulador de eventos.
+Para mais informações, consulte Galileu
+[Adicionar Galileo a um aplicativo CrewAI](https://v2docs.galileo.ai/how-to-guides/third-party-integrations/add-galileo-to-crewai/add-galileo-to-crewai)
+guia prático.
+
+> **Observação**Este tutorial pressupõe que você concluiu o [CrewAI Quickstart](pt-BR/quickstart).
+Se você quiser um exemplo completo e abrangente, consulte o Galileo
+[Repositório de exemplo SDK da CrewAI](https://github.com/rungalileo/sdk-examples/tree/main/python/agent/crew-ai).
+
+### Etapa 1: instalar dependências
+
+Instale as dependências necessárias para seu aplicativo.
+Crie um ambiente virtual usando seu método preferido,
+em seguida, instale dependências dentro desse ambiente usando seu
+ferramenta preferida:
+
+```bash
+uv add galileo 
+```
+
+### Etapa 2: adicione ao arquivo .env do [CrewAI Quickstart](/pt-BR/quickstart)
+
+```bash
+# Your Galileo API key
+GALILEO_API_KEY="your-galileo-api-key"
+
+# Your Galileo project name
+GALILEO_PROJECT="your-galileo-project-name"
+
+# The name of the Log stream you want to use for logging
+GALILEO_LOG_STREAM="your-galileo-log-stream "
+```
+
+### Etapa 3: adicionar o ouvinte de eventos Galileo
+
+Para habilitar o registro com Galileo, você precisa criar uma instância do `CrewAIEventListener`.
+Importe o pacote manipulador Galileo CrewAI por
+adicionando o seguinte código no topo do seu arquivo main.py:
+
+```python
+from galileo.handlers.crewai.handler import CrewAIEventListener
+```
+
+No início da sua função run, crie o ouvinte de evento:
+
+```python
+def run():
+    # Create the event listener
+    CrewAIEventListener()
+    # The rest of your existing code goes here
+```
+
+Quando você cria a instância do listener, ela é automaticamente
+registrado na CrewAI.
+
+### Etapa 4: administre sua Crew
+
+Administre sua Crew com o CrewAI CLI:
+
+```bash
+crewai run
+```
+
+### Passo 5: Visualize os traços no Galileo
+
+Assim que sua tripulação terminar, os rastros serão eliminados e aparecerão no Galileo.
+
+![Galileo trace view](/images/galileo-trace-veiw.png)
+  
+## Compreendendo a integração do Galileo
+
+Galileo se integra ao CrewAI registrando um ouvinte de evento
+que captura eventos de execução da tripulação (por exemplo, ações do agente, chamadas de ferramentas, respostas do modelo)
+e os encaminha ao Galileo para observabilidade e avaliação.
+
+### Compreendendo o ouvinte de eventos
+
+Criar uma instância `CrewAIEventListener()` é tudo o que você precisa
+necessário para habilitar o Galileo para uma execução do CrewAI. Quando instanciado, o ouvinte:
+
+-Registra-se automaticamente no CrewAI
+-Lê a configuração do Galileo a partir de variáveis de ambiente
+-Registra todos os dados de execução no projeto Galileo e fluxo de log especificado por
+  `GALILEO_PROJECT` e `GALILEO_LOG_STREAM`
+
+Nenhuma configuração adicional ou alterações de código são necessárias.
+Todos os dados desta execução são registados no projecto Galileo e
+fluxo de log especificado pela configuração do seu ambiente
+(por exemplo, GALILEO_PROJECT e GALILEO_LOG_STREAM).
