Create a Custom Data Type

Create custom data types for agentic-specific patterns in your organization.

Akto comes with 50+ built-in data types. Create custom types for business-specific patterns in your agent systems.

Common Agentic Custom Data Types

• Transaction IDs (e.g., "TXN_12345")

• Agent IDs or session tokens

• Custom API key formats

• Tool invocation signatures

• Context window identifiers

How to Create

1. Go to Agentic Discovery > Sensitive Data

2. Click Create Custom Data Type

3. Enter name (e.g., "AGENT_SESSION_ID")

4. Define key and value conditions

5. Save

Add Key Conditions

Define how Akto should detect the key:

• Equals to: Exact match (e.g., key = "agent_id")

• Matches regex: Pattern match (e.g., key matches agent_.*)

• Contains: Partial match

Add Value Conditions

Define how Akto should detect the value:

• Matches regex: Pattern for value (e.g., \bagent_[a-z0-9]{16}\b)

• Equals to: Exact value match

• Length: Value length constraints

AktoGPT

Use AktoGPT to generate regex patterns automatically:

1. Click AktoGPT button

2. Describe your pattern (e.g., "agent session ID with prefix")

3. Review generated regex

4. Add to Akto

Example: Agent Session ID

Key Condition: Equals to "agent_session" Value Condition: Matches regex \bagt_[a-f0-9]{32}\b

This detects patterns like: agent_session: "agt_a1b2c3d4..."

Best Practices

• Test regex patterns before adding

• Document custom data types for your team

• Review detected instances to verify accuracy

• Use AktoGPT for complex patterns
