API Security Testing
— ISO 27001 Control Readiness
API Security Testing engineered for the ISO 27001 Control Readiness threat landscape. Every finding is backed by proof-of-concept evidence.
Free Scoping CallISO 27001 Control Readiness Control and Evidence Readiness
Pre-audit technical validation of ISO/IEC 27001 Annex A controls and evidence readiness.
The ISO 27001 Control Readiness control areas most relevant to API Security Testing:
Access Control Policy (A.8.2-8.5)
Validating role-based access, least privilege, and MFA enforcement across APIs and administrative interfaces.
Asset Inventory and Classification (A.5.9-5.13)
Checking that the information-asset inventory and classification labels match live system state, not a stale spreadsheet.
Cryptographic Controls (A.8.24)
Reviewing encryption standards, key management, and TLS configuration for data at rest and in transit.
Supplier Relationship Security (A.5.19-5.23)
Assessing third-party software dependencies and CI/CD integrations for supply-chain risk.
Information Security Incident Management (A.5.24-5.28)
Evaluating detection, classification, and response maturity against logging and traceability infrastructure.
Expected Evidence Examples
- Asset inventory reconciled against live scan results
- Access matrix and MFA coverage report
- Incident-response drill timeline

Frequently Asked Questions
What methodologies do you use?
We base our testing on OWASP Testing Guide, PTES, NIST SP 800-115, and OSSTMM frameworks.
Can we review previous work examples?
Due to NDA constraints we cannot share client names, but we can provide redacted sector-specific case studies and proof summaries.
Do you test remotely or on-site?
Most tests are conducted remotely via VPN. For internal network and physical security tests, we deploy on-site teams.
