API Penetration Testing by Penti
Penti uncovers exploitable weaknesses that often lurk in applications by employing rapid, AI-powered pentesting with human security validation.
Penti’s platform provides ongoing API application penetration testing, which pinpoints real-world attack paths, logic flaws, and authorization failures that can put your organization’s sensitive data and business operations at risk.
API Penetration Testing Overview
APIs are now the largest and fastest-growing attack surface for modern applications. Penti’s platform delivers a comprehensive API pentest experience that combines agentic security testing with expert validation, accelerating the time typically spent on pentesting.
With our API penetration testing tool, Penti continuously evaluates API endpoints across environments, detecting security issues that traditional point-in-time assessments miss. Penti’s platform supports modern development workflows and integrates directly into CI/CD pipelines, enabling continuous testing throughout the API lifecycle.
Penti’s API pentesting tool uses agentic tools to surface common and advanced weaknesses, while certified penetration testers validate findings, uncover business logic flaws, and reduce false positives.
What Penti Helps You Achieve
APIs evolve quickly, and so do security threats. Penti ensures that your company’s targeted security testing aligns with business priorities.

FAQ
What is API penetration testing?
API penetration testing evaluates APIs for exploitable weaknesses by simulating real-world attacks to identify security vulnerabilities.
How is Penti different from traditional API testing?
Penti combines agentic AI penetration testing with expert validation, delivering continuous security insights instead of one-time assessments.
Does Penti support modern API architectures?
Yes. Penti supports REST and SOAP APIs, API specifications, and complex authentication flows.
Can Penti identify business logic flaws?
Yes. Manual testing focuses on business logic, authorization bypasses, and misuse scenarios automated tools can overlook.
How does Penti help with compliance?
Penti supports compliance efforts by providing evidence of ongoing, rigorous security testing and identifying vulnerabilities aligned with OWASP API risks.
Will Penti find undocumented APIs?
Yes. API discovery identifies undocumented and legacy endpoints that increase exposure.
How often are APIs tested?
Testing is continuous, allowing teams to catch new vulnerabilities as APIs change.
Is Penti suitable for fast-moving development teams?
Absolutely. Penti integrates into CI/CD workflows and supports rapid development without adding friction.
