API Penetration Testing
BOLA, token confusion, the endpoint that shouldn’t accept that payload, the workflow you can break by reordering two calls — the kind of API bugs that turn into an incident on a Sunday.
What we’ll look at
- Broken object-level authorization testing
- Token and session handling review
- Rate limiting and abuse controls
- Payment workflow manipulation attempts
- Mass assignment and schema abuse
- Sensitive data leakage testing
What you get
- Endpoint risk summary
- Validated exploit scenarios
- Request and response evidence
- Remediation guidance for developers
- Retest-ready finding register
Why teams book it
- Find authorization gaps before launch
- Protect partner and payment integrations
- Improve confidence in API changes
Common questions
Anything else, just drop us a line.
Yes — a scope and rules of engagement. It covers what’s in, what’s off limits, the test window, and the phone numbers to call if anything looks off mid-test.
In most cases. We write findings so your QSA can map them back to controls, and we’ll join the call if it helps. We can’t sign the RoC ourselves — that’s their job.
Yes. Either include it in the original scope or come back to us once the fixes are in. We re-run the same tests and write up what closed.
