Application security / Authorized assessments
Make sure your API checks permission—not just identity.
A user being signed in does not mean they can access every record. Review authorization boundaries, sessions, token handling and tenant isolation with testable, owner-authorized scenarios.
Quotes and timelines follow scope review. Please do not send credentials or confidential data through public forms.

Trace + retest
Change the account, tenant or object ID in an authorized test and inspect the server decision.
Example security review with controlled test identities.
Common problems
Object-level or function-level authorization weaknesses
Cross-tenant access and mistaken role boundaries
Session/token rotation, expiry and revocation issues
Inconsistent permission checks between mobile and backend
How we approach the work
A written review scope identifying API hosts, test identities, tenant fixture boundaries, access approvals, test windows and safe evidence handling.
01 / Authorize
Confirm owner-approved scope and non-production fixtures.
02 / Model
Document identities, resources, trust boundaries and permission expectations.
03 / Test
Reproduce allowed and denied paths without accessing third-party data.
04 / Verify
Review remediations, retest negative cases and report residual risk.
Typical deliverables
- API permission and trust-boundary matrix
- Reproducible authorized test cases
- Prioritized findings with impact and assumptions
- Remediation retest and handoff notes
Written authorization is required. A scoped review is not a certification, blanket penetration test or promise of zero vulnerabilities.
