API Security Scanner for Testing APIs Before Production
Use ApyGuard as an authenticated API vulnerability scanner to discover what your application exposes and test authorization, OWASP API Security Top 10, and business-logic risks before release.

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

Configure
Set target environments, authentication, and the request context the API expects.
Test
Exercise endpoints for authorization, OWASP, and business-logic weaknesses.
Review & ship
Review reproducible findings, remediation guidance, and bring scans into CI/CD.
What this API vulnerability scanner tests
Test weaknesses that emerge across identities, objects, properties, functions, and unexpected request sequences—not only isolated payloads. Unlike a generic signature scanner, ApyGuard uses API schema and authentication context to build requests for the target being tested.

API security scanner FAQ
What is an API security scanner?
An API security scanner sends controlled requests to API endpoints and evaluates authentication, authorization, input handling, configuration, and business behavior for exploitable weaknesses. A useful scanner supports authenticated, multi-user testing rather than checking only public endpoints and generic payloads.
Is an API vulnerability scanner the same as an API security scanner?
The terms are commonly used for the same category. The important difference is depth: basic scanners look for signatures and malformed-input failures, while API-focused security testing also validates object, function, property, and workflow authorization across identities.
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 API surface into ApyGuard.
Can ApyGuard test authenticated APIs?
Yes. ApyGuard supports authenticated testing using configured credentials and the request context required by the API.
Does ApyGuard test BOLA and IDOR?
Yes. Authorization testing includes BOLA and IDOR, BFLA, and BOPLA scenarios across endpoint, object, and property boundaries.
Can I use ApyGuard in CI/CD?
Yes. ApyGuard supports repeatable API security scans and release gates in CI/CD workflows.
Can I try ApyGuard without a credit card?
Yes. The 7-day trial requires no credit card and currently includes one lifetime scan.
