API Security
Enterprise API Security
Discover, monitor, and protect your APIs from abuse and data exfiltration.
The Challenge
APIs often expose sensitive data and are difficult to secure due to complex business logic and frequent changes (Shadow APIs).
The ZTLayer Solution
Continuous API discovery, schema validation, and behavioral monitoring to detect vulnerabilities like BOLA/IDOR and mass assignment.
Architecture
Our edge nodes parse incoming traffic against uploaded OpenAPI schemas. Deep packet inspection identifies sensitive data (PII) in responses, while behavioral analysis flags abnormal access patterns.
Best Practices
- Upload and enforce OpenAPI schemas for all production endpoints.
- Enable strict content-type validation to prevent parsing attacks.
- Monitor endpoints for excessive data exposure (BOLA).
Enterprise Use Cases
- Protecting mobile app backend APIs.
- Securing B2B partner integrations.
- Meeting PCI-DSS requirements for API data protection.
