Secure the Backbone of Your Digital Applications
APIs are the invisible backbone of modern digital infrastructure - but they’re also prime targets for cyberattacks. At Specialty Experts, we offer API Penetration Testing (API-PT) to uncover and remediate security flaws before attackers exploit them. Our CREST-certified experts use real-world offensive techniques - simulating attacker behavior - to assess API logic, backend integrations, and data flows. Whether you're using REST, SOAP, or custom-built interfaces, we eliminate blind spots and harden your API ecosystem against intrusion.
Why API Security Testing Is Business-Critical ?
APIs transmit critical business data across systems - making them high-value targets. A single misconfigured endpoint can lead to data leaks, financial loss, or full system compromise.
Our API penetration tests help you:
- Detect vulnerabilities in API logic and authentication flows
- Evaluate exposure due to misconfigurations or poor access control
- Ensure compliance with security frameworks such as OWASP API Top 10, PTES, and OSSTMM
- Improve your API’s performance, reliability, and trustworthiness
What We Cover in Our API Penetration Testing?
Our testing targets both common and complex vulnerabilities, including:
Our API penetration tests help you:
- Broken authentication and token flaws
- Excessive data exposure
- Mass assignment vulnerabilities
- Insecure CORS implementations
- Missing object- or resource-level access controls
- Improper rate limiting and DoS weaknesses
- CSRF (Cross-Site Request Forgery)
- Client-side injection and XSS
Our Proven API Testing Methodology
We follow a multi-phase, zero-assumption approach to API security:
Scoping and Planning
We define clear testing objectives and identify APIs (internal, external, public, or third-party) within scope.
Reconnaissance and Enumeration
Using advanced intel-gathering techniques, we map endpoints, identify exposed functions, and detect weak authentication schemes.
Vulnerability Discovery
Both automated tools and manual exploitation are used to test business logic, abuse authorization flows, and simulate abuse scenarios.
