The coverage gap
A passing functional test is not a security test
Traditional tests follow expected paths. Attackers look for undocumented endpoints, inconsistent authorization, writable sensitive properties, and differences between a specification and the running API.
- Undocumented endpoints
- Authorization gaps
- BOLA, BFLA, and BOPLA
- Business-logic abuse
- Spec/runtime differences
- Misconfigured authentication

API security testing FAQ
What is API security testing?
API security testing exercises an API's endpoints, authentication, authorization, inputs, and business behavior to find weaknesses before attackers do.
Does ApyGuard require an OpenAPI specification?
OpenAPI is one supported starting point. Teams can also build an inventory from source with APIScout or from observed browser traffic, then bring that surface into ApyGuard.
Can ApyGuard test authenticated APIs?
Yes. ApyGuard supports authenticated testing using configured credentials and request context.
Does ApyGuard test BOLA/IDOR?
Yes. Authorization testing includes BOLA/IDOR, BFLA, and BOPLA scenarios.
Can I use it in CI/CD?
Yes. ApyGuard supports CI/CD-integrated security scans for release workflows.
Can I try ApyGuard without a credit card?
Yes. The 7-day trial requires no credit card and currently includes one lifetime scan.
