API Penetration Testing
API Penetration Testing
API penetration testing is crucial because APIs serve as a bridge between different software systems, often handling sensitive data and critical functionalities. With the increasing reliance on APIs in modern applications, they have become prime targets for attackers. API Pen Testing helps identify vulnerabilities such as authentication flaws, data exposure, and improper rate limiting, ensuring robust security measures are in place. By uncovering these weaknesses before malicious actors can exploit them, API Pen Testing protects sensitive data, enhances application reliability, and ensures compliance with security standards and regulations.

Why API Penetration Testing?
- Many Compliance regulations demand regular Penetration Testing
- Customers and partners may require proof of regular pen testing
- What if a competitor or hacker would steal your digital assets?
- What legal consequences would a security breach have for you?
- What would be the financial implications if your systems or applications are taken down?
- What reputational damage would a breach pose to your business?
- Proactive security investment instead of reactive repair costs
- Automated scanners cannot find many modern vulnerabilities such as IDORs and business logic flaws
Service Description
This service examines APIs (Application Programming Interfaces). These APIs can range from old ones like SOAP/XML to RESTful APIs, GraphQL APIs and gRPC protbuf APIs. We closely follow the OWASP Top 10 Framework for API Testing. It involves attempts to actively exploit vulnerabilities in order to demonstrate data leakage and gaining access to API functionality (Create, Read, Update, Delete – CRUD).
Tests performed
Our testing methodologies are aligned with the OWASP Top 10 API framework. This includes Recon and Enumeration as well as testing for Broken Object Level Authorization, Broken Authentication, Broken Object Property Level Authorization, Unrestricted Resource Consumption, Broken Function Level Authorization, Unrestricted Access to Sensitive Business Flows, Server-Side Request Forgery, Security Misconfiguration, Improper Inventory Management and Unsafe Consumption of APIs.
Deliverables
- Full report (Executive summary and in-depth technical report)
- Mitigation Advice on encountered vulnerabilities
- Instant notification of critical vulnerabilities found during testing phase
- Secure report delivery by encrypted email
Flexible Options
- Black-box (from an attacker’s perspective without credentials)
- Grey-box (from a malicious user’s perspective with user credentials)
- White-box (with full admin credentials and access to source code)
- External testing (Internet facing) or internal testing via VPN
- Packages for recurring and continuous testing available
- Impact minimization by protection from malicious exploits or DDoS tests
- Fine grained scoping and testing only during agreed schedule
