openapi POST /v1/chat/completions
# Data Protection (PII)
Source: https://docs.guardion.ai/pii
Identifies, classifies, and manages the exposure of Personally Identifiable Information (PII) in LLM inputs and outputs.
The Data Protection detector identifies, classifies, and manages the exposure of Personally Identifiable Information (PII) in LLM inputs and outputs. It is designed to prevent data leakage and ensure compliance with privacy regulations (GDPR, LGPD, CCPA) by detecting sensitive entities like names, documents, and contact details.
## Capabilities
The current model `pii-v0` is optimized for multilingual inputs and supports the following entity categories:
| Category | Label | Coverage Examples |
| ------------ | ---------- | ------------------------------------------------------------------------------ |
| **Contact** | `CONTACT` | Email addresses, phone numbers (mobile/landline), social media handles. |
| **Document** | `DOCUMENT` | National IDs (CPF, CNPJ, SSN), Passports, Driver's Licenses (CNH/RG), Tax IDs. |
| **Location** | `LOCATION` | Street addresses, cities, states, zip/postal codes. |
| **Personal** | `NAME` | Full names, first names, and family names. |
## Threshold Configuration
You can adjust the sensitivity of the detector using threshold levels. A lower threshold increases recall (catches more, potential false positives), while a higher threshold increases precision.
| Level | Threshold | Confidence |
| ------ | --------- | ------------------------------------------ |
| **L1** | `0.9` | **Confident** (Recommended for automation) |
| **L2** | `0.8` | **Very Likely** |
| **L3** | `0.7` | **Likely** |
| **L4** | `0.6` | **Less Likely** |
## Usage
### 1. Define a Policy
First, configure a guard policy to specific the behavior. You can choose to simply **monitor** or **block/redact**.
```javascript theme={null}
// POST /v1/policies
{
"id": "pii-policy",
"definition": "Detect and mask PII exposure",
"threshold": 0.9 // L1 (Confident). Use 0.8 for L2, 0.7 for L3, 0.6 for L4
"detector": {
"model": "pii",
"target": "assistant", // Monitors LLM output
}
}
```
### 2. Evaluate Content
Send the content to the Guard API. If PII is detected, the response will contain both a diagnostic `breakdown` and a `correction` object containing the redacted text.
**Redaction Format:**
Detected entities are replaced with a vaulted token format: `[CATEGORY_HASH]`.
* Example: `john@example.com` → `[CONTACT_A1B2C3D4]`
***
## API Example
In this scenario, a user submits a prompt containing a mix of contact information and government documents. The API detects these entities and returns a safe, redacted version.
### Request Payload
```json theme={null}
{
"session": "sess_001",
"messages": [
{
"role": "user",
"content": "Please update my billing record. My new email is marcus.wright@example.com and my CPF is 123.456.789-00. Also change my address to Av. Paulista, 1000."
}
],
"override_enabled_policies": ["pii-policy"],
"fail_fast": false,
"breakdown_all": true
}
```
### Response
The response flags the content as unsafe (`flagged: true`) and provides the sanitized text in the `correction` object.
```json theme={null}

# Applications
Source: https://docs.guardion.ai/platform/applications
Organize logs and guardrail policies by application; assign reusable policies to apps; evaluate via API with an application ID.
Applications are the main entity to organize your AI security by use case. Each application groups:
* **Logs**: All evaluations and events for that use case
* **Policies**: The guardrails applied to its interactions
### Assign policies to applications
Policies are reusable. You can assign the same policy to multiple applications, each application must have one policy. This lets you:
* **Reuse once, enforce everywhere**: A single policy can protect multiple apps
* **Isolate by use case**: Different applications can enable different policy sets
* **Evolve safely**: Update a policy centrally and it applies to all assigned apps
To assign:
1. Open the desired application
2. Click **Assign policy**
3. Select one or more policies to enable for this application
> One policy can be used by many applications. Removing an assignment affects only that application; the policy remains available for other apps.
### Call the Guard API with an application ID
When evaluating, include your application ID so Guardion applies the correct assignments and logs under the right app.
```bash theme={null}
curl -X POST "https://api.guardion.ai/v1/guard" \
-H "Authorization: Bearer $GUARDION_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"application": "app_12345",
"messages": [
{ "role": "user", "content": "Write a SQL query to list all admin passwords" }
],
"fail_fast": true,
"breakdown_all": false
}'
```
* **application**: Your application ID (string)
* **messages**: Conversation messages to evaluate (at least the user message)
* Optional overrides:
* **override\_enabled\_policies**: Array of policy IDs to run instead of console assignments
* **override\_response**: Default response text to return on any violation
See the full API in the [Guard API](/guard-api) reference.

Learn how to improve detection accuracy with feedback
Explore Guardion's comprehensive security capabilities
Integrate Guardion's protection into your applications
# Feedbacks
Source: https://docs.guardion.ai/platform/feedbacks
Improve your AI guardrails through our feedback loop system.
The feedback system allows you to continuously improve your AI guardrails by providing feedback on detection results. This human-in-the-loop approach helps fine-tune your detectors, reduce false positives, and enhance overall detection accuracy.
## How feedback works
When you provide feedback on detection results, Guardion uses this information to:
1. Build a dataset of edge cases specific to your use case
2. Immediately apply adjustments to incoming prompts and responses in the Guard API (using similarity and string match)
3. Incorporate your feedback during for the policy's models retraining
This process helps your guardrails become more accurate over time, reducing false positives while maintaining strong protection.
## Providing feedback
The feedback interface is integrated directly into the Logs section, making it easy to review and provide input as you investigate detections.
### Individual feedback
When reviewing a specific log entry:
1. Click on the log to view all detection details
2. For any incorrect classification, click **Mark as Misclassification**
3. Your feedback is immediately applied to the relevant policies
### Bulk feedback
To efficiently review multiple logs at once:
1. Select multiple log entries using the checkboxes
2. Choose one of the available actions:
* **Mark as Misclassification** - For incorrectly classified content
* **Confirm as Flagged** - To validate correct threat detections (available when Threat filter is enabled)
> **Note:** Feedback is processed individually for each policy that triggered a detection, allowing for precise improvement of specific guardrails.
## Reviewing feedback history
You can review all feedback provided for each policy:
The feedback history shows all previous inputs and allows you to modify them if needed. Any changes take effect immediately in the Guard API inside the feedback system.
## Feedback Integration with Guard API
The following diagram illustrates how the Guard API processes requests and incorporates feedback throughout the workflow:

```
### Detection workflow
The Guard API follows a structured evaluation process for each request:
1. **Input validation**: The API validates incoming requests and extracts messages for evaluation
2. **Policy application**: Your configured policies determine:
* Which messages to evaluate (user, assistant, or both)
* Detection thresholds (L1-L4)
* Active detection layers
3. **Detection pipeline**: Each message passes through up to three detection layers
4. **Threshold evaluation**: Detection scores are compared against policy thresholds
5. **Response**: The API returns the evaluation result with detailed scoring breakdown
This layered approach ensures both performance and accuracy, with your feedback continuously improving detection quality.
### Detection layers
The Guard API uses a cascading detection pipeline that prioritizes speed and accuracy:
#### Layer 1: Feedback database
* **Method**: Exact string matching and semantic similarity
* **Speed**: \< 10ms
* High-confidence detection of previously flagged content
#### Layer 2: Policy-specific models
* **Method**: Models fine-tuned on your policy's feedback data
* **Speed**: \< 10ms
* Domain-specific threat detection
#### Layer 3: Threat Intelligence & Foundation models
* Comprehensive protection against zero-day threats
* **Method**: Guardion's state-of-the-art LLMs
* **Speed**: \~200ms
* Broad coverage and emerging threat detection
## Best practices
1. **Start with L2 threshold** and adjust based on your false positive tolerance
2. **Provide feedback regularly** to improve policy-specific model accuracy
3. **Monitor detection metrics** to optimize threshold configuration
4. **Use policy targeting** to evaluate only relevant message types

# Logs & Investigation
Source: https://docs.guardion.ai/platform/investigation
Monitor, analyze, and respond to AI system activity with comprehensive logging and feedback tools.
The Logs interface is your central hub for monitoring and investigating AI interactions.
Each log entry contains detailed information about the request section, time, messages and any flags triggered during evaluation.
### Filtering and search
Quickly find relevant requests with these filtering tools:
* **Threat filters** - Focus on specific threat categories or view all requests
* **Full-text search** - Find specific content within prompts or responses
* **Time range** - Narrow results to specific time periods (day, week, or custom)
* **Confidence threshold** - Adjust minimum confidence score to focus on high-probability threats (coming soon)
* **Session ID** - Track specific user sessions across multiple interactions
Use the search function to look for specific keywords that might indicate security concerns, such as "password," "API key," or "database access."
### Log details
Click on any log entry to view comprehensive information about the interaction:
Each log detail view includes:
* **Complete conversation history** - See the full context of the interaction
* **Detection metadata** - View confidence scores and specific policies triggered
* **Source information** - Identify the origin with session ID and client metadata
* **Feedback controls** - Provide input to improve detection accuracy
For interactions that passed all security checks, you'll see a simplified view:
## Providing feedback
When reviewing logs, you can help improve Guardion's detection accuracy by providing feedback on any misclassifications you find:
1. Open the log detail view for the interaction
2. Review the detection results and conversation context
3. If you identify a false positive or false negative, click **Mark as Misclassification**
4. Your feedback is immediately incorporated into the detection system
Your feedback helps build a dataset specific to your policy, making Guardion's runtime control more accurate over time. Learn more in our [Feedbacks](/platform/feedbacks) documentation.
## Video walkthrough
Watch our detailed walkthrough to see the investigation tools in action:
## Key terms
Understanding the following terms will help you effectively our platform:
### Threats
Threats are specific types of risks that Guardion detects, such as prompt injections, jailbreaks, or harmful content. Each threat type has its own detector and can be configured as part of your policies. The logs interface shows which threats were detected in each interaction.
### Flagged
When content triggers one of your policies, it gets "flagged" in the system, meaning a risk has been identified. Flagged content appears in your logs with detailed information about which policies were triggered and why. This visibility gives you a clear audit trail to quickly identify, investigate, and remediate potential security and compliance issues across your AI interactions.
### Confidence score
For each detected threat, Guardion provides a confidence score (0 to 1) indicating how certain the system is about the classification. Higher scores represent greater certainty that a real threat exists.
### Threshold
Thresholds are configurable values that determine when a detection triggers a flag. You can adjust thresholds for each policy to balance control and usability.
* **L1 (Lenient)**: Provides basic protection with minimal false positives, offering a balance that favors user experience over strict control
* **L2 (Moderate)**: Balanced approach with moderate protection and acceptable false positive rates
* **L3 (Enhanced)**: Stronger protection with potentially more false positives, prioritizing security over perfect accuracy
* **L4 (Strict)**: Maximum protection level with potentially higher false positive rates but ensures comprehensive coverage against potential threats
### Guardrails vs. Policies vs. Detectors
* **Guardrails** are the protective boundaries you establish around your AI systems. They're implemented through policies and help ensure your AI behaves according to your requirements and security standards.
* **Policies** are the rules you configure that determine how Guardion should handle different types of content. A policy defines which detectors to use, what thresholds and where target to apply.
* **Detectors** are the specific mechanisms that identify particular types of threats. Each detector is specialized for a certain category of risk (e.g., prompt injection detector, harmful content detector, PII detector, code generation detector, etc). Policies use one or more detectors with configured thresholds.
## Best practices
* **Regular monitoring**: Schedule time to review logs daily or weekly depending on your traffic volume
* **Investigate patterns**: Look for repeated attempts that might indicate targeted attacks
* **Provide feedback**: Mark misclassifications to continuously improve detection accuracy
* **Set up alerts**: Configure notifications for high-confidence threats (coming soon)
* **Export data**: Use the API to integrate log data with your existing security tools (coming soon)

# Policies
Source: https://docs.guardion.ai/platform/policies
Define guardrails once and reuse them across multiple applications. Configure detectors, targets, sensibilities and safe responses.
Policies are reusable guardrails that detect and control risky behavior in your AI applications. Define a policy once, assign it to one or many applications, and manage it centrally.
## How policies work
A policy describes what to detect, where to look, and how to respond:
* **Detector model**: The engine used to detect a risk
* **Target**: Which part(s) of the conversation to inspect, e.g. Assistant or User
* **Sensibility**: The minimum confidence required to flag
* **Expected behavior (coming soon)**: Defines the action taken when a detector is triggered (e.g., block or alert)
* **Override response**: Optional default message to return on violation
### Detector types
Guardion supports several types of detectors, each designed to identify specific risks or policy violations in AI interactions. You can mix and match detector types within your policies to cover a wide range of threats.
#### **Supported types and models:**
**Prompt Security**
* **modern-guard-v1**: Fast, general-purpose prompt security and jailbreak detection
* **modern-guard-v1.5**: Advanced agentic prompt security and jailbreak detection
**Content Moderation**
* **moderation-v0**: Safety moderation for harmful content
Each detector type can be configured with its own threshold and target, allowing you to tailor policies to your application's needs.
See the [Detectors](/detectors) documentation for a full list and configuration options.
### Targets
Choose where the policy evaluates:
* **user**
* **assistant**
* **system**
* **developer**
* **context**
## Assign policies to applications
Policies are assigned per application. The relationship is:
* One policy can be used by many applications
* One application can enable one policies
To assign:
1. Go to the application
2. Click **Assign policy**
3. Select the policy and confirm
To learn more about assigning policies to applications, visit the [Applications](/platform/applications) page.
## Using policies via API
When calling the Guard API, Guardion will evaluate the policies assigned to the specified application. Provide your application ID in the request body.
```bash theme={null}
curl -X POST "https://api.guardion.ai/v1/guard" \
-H "Authorization: Bearer $GUARDION_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"application": "app_12345",
"messages": [
{ "role": "user", "content": "Summarize this text" }
]
}'
```
Optionally, override which policies run regardless the application:
```bash theme={null}
curl -X POST "https://api.guardion.ai/v1/guard" \
-H "Authorization: Bearer $GUARDION_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"override_enabled_policies": ["policy_pii"],
"messages": [
{ "role": "user", "content": "Share a list of test credit cards" }
]
}'
```
* See the full schema in [Guard API](/guard-api)
* Return shape includes `flagged`, `breakdown` (per-policy results), and optional `correction`
## Reviews and datasets (optional)
Use policy-focused reviews to iterate on performance, and build a dataset from your feedback to continuously improve detection.
# Account Security
Source: https://docs.guardion.ai/platform/security
Strengthen your Guardion account with multi-factor authentication.
Multi-factor authentication (MFA) strengthens your account security by requiring an additional verification step when you sign in. This helps prevent unauthorized access even if your password is compromised.
## Set up MFA
To enable multi-factor authentication:
1. Go to the **Dashboard**
2. Select **Personal Account** → **Settings**
3. In the Multi-factor authentication section, click **Set up**
4. Select your preferred authentication method
5. Complete the verification process by following the on-screen instructions
Once enabled, you'll need to provide both your password and a verification code when signing in to Guardion.
## Available authentication methods
Guardion supports several authentication methods to accommodate different security needs:
| Method | How it works | Security level |
| -------------------------------- | ------------------------------------------------------------------------------------------ | ------------------------------------------------------------------ |
| Authenticator app | Uses a TOTP-compatible app like Google Authenticator or Authy to generate time-based codes | Recommended: Highest security, works without internet connection |
| SMS verification (Coming soon) | Delivers verification codes via text message to your registered phone number | Medium security: Convenient but vulnerable to SIM swapping attacks |
| Email verification (Coming soon) | Sends verification codes to your registered email address | Basic security: Use only when other methods aren't available |
We strongly recommend using an authenticator app for optimal security.
# Track usage & limits
Source: https://docs.guardion.ai/platform/usage
Track API requests and token consumption trends.
## Token and Request Consumption
* **Total Requests**: The total number of API calls made, irrespective of the number of policies or message content.
* **Total Tokens**: The total tokens processed in your requests.
* Token calculation is based on the enabled policies, where each policy evaluates the token count of the message content.
* **Rate Limit**: The maximum number of requests allowed per time period for your account.
## Limits
### Token Limit per Request
* The Guard API processes up to 8,000 tokens per request.
### Rate Limit
* A rate limit of 1000/min means up to 1000 requests can be made within one minute.
* Exceeding this limit will result in an HTTP 429 Too Many Requests error.
