Advanced API security & performance testing
Protect your digital infrastructure with a modular assessment of your APIs — security, performance, documentation and compliance — and a clear, prioritised report.
APIs are the new attack surface
Security risks
Poorly secured APIs expose sensitive data and business logic, and are a primary vector for data breaches.
Performance issues
Slow or unreliable APIs hurt user experience and operations, and increase costs.
Documentation gaps
Incomplete or inconsistent documentation slows integrations for your team and partners.
Compliance
APIs must align with standards such as GDPR, HIPAA, PCI-DSS and OWASP guidance.
Four modules, one report
Security analysis
- Detect vulnerabilities and attack vectors (OWASP API Top 10)
- Evaluate authentication, authorisation and token security
- Examine CORS configuration, input validation and data exposure
Performance testing
- Measure response times under different load conditions
- Load, stress and spike testing
- Identify constraints and bottlenecks
Performance testing is available on request.
Documentation & data quality
- Assess clarity, consistency and completeness of API docs
- Evaluate data-model quality and standards compliance
- Recommendations to improve documentation
Compliance & protocol
- Check alignment with regulatory standards and OWASP recommendations
- Protocol-level optimisation checks
- HTTP/2 support, caching and compression analysis
From specification to action plan
- 1 · Specification analysisExtract endpoints, data structures, security requirements and metadata to build a complete API model.
- 2 · Security analysisAuthentication, authorisation, injection, rate limiting, data exposure, CORS and input validation checks.
- 3 · Performance testingResponse time, steady-load, increasing-load and endurance testing.
- 4 · Documentation analysisCompleteness, clarity and consistency, plus data-model quality.
- 5 · ReportingDetailed findings with actionable recommendations for security, performance and compliance.
Where the API Analyzer helps
Payment APIs before launch
Validate token security, rate limiting and error handling of a payment-processing API before it goes live, and document the fixes for auditors.
Healthcare data exchange
Check a patient-data API for sensitive data in error messages, access-control gaps and missing audit logging as part of a HIPAA readiness review.
