FAQPage Schema
How do I automate API security testing for GraphQL and REST endpoints?

You can automate API security testing across GraphQL, REST, and WebSocket interfaces by pointing the assessment tool at your API surface to discover endpoints, map authorization, and execute vulnerability tests like BOLA and SSRF.

What types of API vulnerabilities can I test for during pentesting?

API vulnerability testing covers BOLA, IDOR, SSRF, and injection flaws across GraphQL, REST API, and WebSocket interfaces, generating structured evidence reports for security engineering and pentesting teams.

Can I use this for security assessments of cloud-native microservices in CI/CD?

Yes, this API security assessment is designed for cloud-native architectures and microservices in CI/CD pipelines, validating authentication and authorization controls while testing REST, GraphQL, and WebSocket interfaces.

How do I validate authentication and authorization controls across WebSocket APIs?

Validating authentication and authorization controls across WebSocket APIs involves mapping endpoint surfaces, testing access boundaries, and executing vulnerability tests to identify exposure in real-time communication interfaces.

Does API security testing work without external dependencies?

Yes, API security testing operates with no external dependencies, running structured vulnerability assessments and endpoint discovery natively across GraphQL, REST API, and WebSocket interfaces.
