Comprehensive API Penetration Testing

We combine advanced automated fuzzing with hands-on techniques—testing authentication, authorization, rate-limiting, schema abuse, injection vectors, and business-logic bypasses—to expose weaknesses in your APIs before attackers do. You’ll receive a detailed, proof-of-concept–driven report mapped to your compliance needs, plus complimentary retesting to confirm every remediation.

Key Benefits of API Pentesting

Secure your APIs, satisfy auditors, and stop breaches before they happen.

Audit-Ready API Security

Our assessments map directly to leading compliance frameworks—PCI DSS, HIPAA, ISO 27001, SOC 2, GDPR/CCPA—and provide exportable evidence packages and control-traceability matrices so you can demonstrate due-diligence to auditors and regulators.

Expert-Led API Analysis

Work hand-in-hand with our API security specialists, who guide you through every step—from scoping and endpoint enumeration to proof-of-concept exploit development—ensuring you fully understand each vulnerability and its remediation roadmap.

Proactive Vulnerability Discovery

We combine automated fuzzing with manual techniques to uncover injection flaws, broken authentication/authorization, rate-limit bypasses, business-logic abuse, schema manipulation (GraphQL), and other subtle attack paths—letting you neutralize risks long before real attackers strike.

Overview of API Penetration Testing

Holistic API Security Coverage

We audit every facet of your API ecosystem—from REST endpoints and GraphQL schemas to microservices and serverless functions—identifying and exploiting OWASP API Top 10 risks (injection, broken object level auth, excessive data exposure) as well as emerging threat vectors.

Realistic Attack Simulation

Using a blend of automated fuzzing, custom scripts, and manual techniques, we mimic real-world adversaries: bypassing authentication, escalating privileges, chaining multi-step attacks, abusing business logic, and stress-testing rate limits to expose hidden weaknesses.

Seamless Remediation & Validation

You’ll receive a prioritized, compliance-mapped report complete with proof-of-concept exploits and clear fix-it guidance. Throughout the engagement, our researchers provide direct feedback, and we include complimentary retesting to verify every remediation before sign-off.

Key Testing Areas

Our API penetration tests rigorously evaluate critical domains to safeguard your application’s confidentiality, integrity, and availability.

Authentication Testing

We probe your login and token-issuance flows—examining OAuth, JWT handling, and API keys—to ensure only valid credentials permit access and that brute-force, replay, and credential-stuffing attacks are thwarted.

Authorization Testing

We verify access controls at every endpoint, confirming that users cannot perform actions or view resources outside their permitted scope. This prevents both horizontal (same-level) and vertical (privilege escalation) bypasses.

Input Validation Testing

Every input vector—URL parameters, headers, JSON bodies, multipart data—is fuzzed and manipulated to detect SQL/NoSQL injection, XML bombs, command injection, and other malformed-payload exploits that could compromise your service.

Business Logic Testing

Under adversarial scenarios, we simulate multi-step workflows, race conditions, and state-transition abuses to uncover flaws that automated scanners miss—ensuring your API enforces correct order, limits, and transactional integrity.

Error Handling Testing

We trigger edge-case and error conditions to confirm that exceptions never leak sensitive data, stack traces, or internal implementation details—so attackers gain no unintended reconnaissance or attack vectors.
