API Security
Threat modeling, authentication and authorization audits, and OWASP API Top 10 coverage for your API surface.
Secure Your API Surface
APIs are the primary attack surface for modern applications — they expose business logic directly, operate at scale, and are frequently deployed faster than security reviews can keep pace with. Common failures are predictable: broken object-level authorization, missing rate limiting, excessive data exposure, and authentication gaps. The OWASP API Security Top 10 describes the pattern set that attackers exploit consistently.
Jacobian's API security engagements combine threat modeling with technical testing. We review authentication and authorization design, test for the OWASP API Top 10, evaluate rate limiting and abuse prevention controls, and assess API documentation and versioning practices for unintended exposure. Output is a prioritized finding set with remediation guidance implementable by your development team.

OWASP API Top 10 Coverage
Systematic testing against the documented failure modes most commonly exploited in API breaches, not ad hoc testing against a custom scope.
Auth Design Review
Authentication and authorization are evaluated at the design level, not just tested for obvious bypass — catching structural problems that testing alone may miss.
Developer-Usable Output
Findings include specific, actionable remediation guidance written for developers, not just security generalists.
Our API Security Process
From discovery to remediation support.
API Inventory and Threat Modeling
Document the API surface, authentication flows, data exposed, and consumer trust boundaries; identify high-risk areas to prioritize.
Technical Testing
Test against OWASP API Top 10 categories, validate rate limiting and abuse controls, and evaluate authentication and authorization implementation.
Findings Report and Remediation Support
Deliver prioritized findings with remediation guidance; available for remediation review to confirm fixes before re-test.
