API Penetration Testing
Application Programming Interfaces (APIs) are a set of rules or protocols that allow for disparate software applications to seamlessly communicate with each other to exchange data, features and functionality.
APIs can present a security risk for several reasons including, but not limited to:
- Exposure of sensitive data
- Broken object-level authorization
- Broken authentication
- Excessive data exposure
- Lack of resource and rate limiting
- Security misconfiguration
Canary Trap’s API penetration testing is aligned with achieving the following goals and objectives:
Security Assurance: Helps to ensure that your APIs are secure from potential attacks.
Data Protection: APIs can often be a gateway to sensitive data. We will ensure the data within the in-scope APIs are protected from unauthorized access or security breaches.
Compliance: Many industries have regulations that require regular security testing, including APIs, to protect consumer data.
Trust: By securing your APIs, you build trust with your customers and partners who rely on the integrity of your systems.
Penetration testing will identify weaknesses that exist within your security model. Committing to undertake regular offensive security (penetration) testing will help to ensure that your organization can remain vigilant and resilient to new and emerging cyber threats. Undertaking API penetration testing can assist with improved planning when it comes to business continuity and disaster recovery.
Canary Trap combines human expertise with sophisticated tools, proven methodologies and, where appropriate, threat intelligence to ensure a thorough, in-depth approach to security testing and assessments.

FAQs
What is API Penetration Testing?
API Penetration Testing is a security assessment that identifies and exploits vulnerabilities in Application Programming Interfaces (APIs). It simulates real-world attacks to ensure APIs that connect your applications, services, and users are secure against unauthorized access and data breaches.
Why is API penetration testing important for my organization?
APIs often handle sensitive data and are a common target for attackers. Testing helps prevent data exposure, validates authentication and authorization mechanisms, ensures compliance with standards like PCI-DSS and GDPR, and strengthens trust in your digital services.
What types of vulnerabilities are commonly found in APIs?
Our assessments often uncover:
- Broken authentication and authorization
- Excessive data exposure
- Injection flaws (SQL, NoSQL, command injection)
- Insecure direct object references (IDOR)
- Rate limiting and throttling weaknesses
- Misconfigured CORS (Cross-Origin Resource Sharing) policies
How often should APIs be tested?
We recommend testing before every major release and at least annually for production APIs. Frequent updates, integrations, and evolving threats make regular testing essential to maintaining security.
What deliverables will Canary Trap provide after the test?
You’ll receive a comprehensive Findings Report that includes:
- Executive summary for leadership teams
- Detailed technical findings with severity ratings
- Proof-of-concept exploits (where applicable)
- Actionable remediation guidance for developers
- Findings review meeting with our security experts
