API Security Audit

API security testing that ends in proof, not a checklist.

Authorization gaps, tenant-isolation breaks, and OWASP API Top 10 risks — found, proven, and validated closed. For REST, GraphQL, and AI-agent tool APIs.

What gets tested

Where APIs actually fail

Authentication is rarely the problem. Authorization, tenant boundaries, and sensitive-action protection are where modern APIs leak — and where Telhawk focuses.

Authorization & object access

Broken object-level authorization (BOLA), broken function-level authorization, IDOR, and missing ownership checks on every endpoint.

Tenant boundaries

Multi-tenant isolation across reads, writes, exports, webhooks, and admin paths — including the endpoints customers don't know exist.

Auth model & session hygiene

Token issuance, scope handling, refresh, revocation, key rotation, and the gap between authentication and authorization.

Sensitive actions & rate limits

Money movement, data exports, admin operations, and AI-agent tool calls — plus rate limiting, abuse protection, and audit logging.

Coverage

OWASP API Security Top 10, end to end

Every Telhawk API security audit maps findings to the OWASP API Top 10, so security review boards and procurement teams see the coverage they expect.

API1 — Broken Object Level Authorization
API2 — Broken Authentication
API3 — Broken Object Property Level Authorization
API4 — Unrestricted Resource Consumption
API5 — Broken Function Level Authorization
API6 — Unrestricted Access to Sensitive Business Flows
API7 — Server Side Request Forgery
API8 — Security Misconfiguration
API9 — Improper Inventory Management
API10 — Unsafe Consumption of APIs
Why Telhawk

API penetration testing with proof attached.

Authorization-first
BOLA, BFLA, and tenant-isolation are the breach pattern. We start there, not at the login page.
Reproducible findings
Every finding is a request you can paste into curl. No vague "could be exploited" language.
Validated fixes
We retest after remediation. The engagement closes when the paths actually close.
Deliverables

What you get from a Telhawk API audit

Endpoint-by-endpoint findings with reproducible requests
Tenant-isolation evidence for every multi-tenant path
OWASP API Top 10 coverage map
Remediation guidance keyed to your framework
Validation round confirming each fix closes the path
FAQ

Common questions about API security testing

How is this different from a generic web pentest?

Web pentests probe pages and forms. An API security audit follows authorization, tenant boundaries, and sensitive actions across machine-to-machine traffic — the layer where the worst breaches happen.

Do you need a staging environment?

A separate, data-realistic environment is strongly preferred. Telhawk can also work against production with safety boundaries when staging isn't representative.

What about AI agent tools and MCP servers?

Same model. An agent tool is an API call with a model in front of it. We test the underlying authorization, scope, and abuse paths the same way we'd test any sensitive endpoint.

Ready for an API security audit with proof?

Telhawk tests APIs the way real attackers reach data — through authorization gaps and tenant-boundary breaks — and proves every finding.
