APIs connect applications, users, services, and critical business systems, making them a core component of modern digital infrastructure. Poor authentication, broken authorization, excessive data exposure, insecure configurations, and business logic flaws can expose sensitive information and critical functionality.
Our API Security Testing services identify vulnerabilities across REST, SOAP, GraphQL, and other API architectures through automated analysis and expert-led manual penetration testing.
Overview
We evaluate APIs from an attacker's perspective, testing authentication, authorization, input validation, business logic, data exposure, rate limiting, configuration, and API workflows.
Our API Penetration Testing helps organizations discover vulnerabilities that could allow attackers to access unauthorized data, manipulate transactions, bypass security controls, or abuse critical business functionality.
Scanning tools surface breadth; our experts go deep with manual exploitation of every API endpoint.
Every API finding manually validated before it reaches your team — no unverified false positives.
Unlimited retests for 90 days — we verify every finding is closed after remediation.
Assessments structured around OWASP API Security Top 10 and recognized industry standards.
What We Offer
Six focus areas designed to secure APIs across authentication, authorization, data protection, business logic, and infrastructure.
Perform comprehensive security testing of APIs to identify vulnerabilities that could enable unauthorized access, sensitive data exposure, privilege escalation, transaction manipulation, or abuse of business functionality.
Assess API authentication mechanisms, tokens, OAuth implementations, JWTs, API keys, session management, and authorization controls to identify weaknesses that could allow unauthorized users to access protected resources.
Test object-level and function-level access controls to identify vulnerabilities where users can access resources or functionality outside their intended privileges — the most critical OWASP API risks (BOLA / BFLA).
Assess API parameters, request bodies, headers, query strings, and other inputs for injection vulnerabilities, improper validation, malformed input handling, and unexpected application behavior.
Analyze API workflows and business processes to identify logic flaws, transaction manipulation, replay attacks, parameter tampering, workflow bypasses, and other application-specific vulnerabilities.
Evaluate API security configurations, error handling, excessive data exposure, rate limiting, HTTP methods, security headers, documentation exposure, and other configuration weaknesses.
Our Advantage
Six outcomes your organization gains from a Woollemia API security assessment.
