API Security Assessments That Shut Down Supply‑Chain Breaches
Modern apps run on APIs—and attackers know it. InfoSight’s API security assessment combines automated fuzzing with manual API penetration testing to expose logic flaws, broken authentication, and hidden injection paths across micro‑services and third‑party integrations. Mapped to OWASP API Top 10 and NIST 800‑53, our deliverables give you a clear, prioritized remediation plan before a single record leaks.
Download Assessment Overview 
The Challenge
APIs now move more data than web browsers. Weak authentication, over‑privileged tokens, and vulnerable open‑source libraries let threat actors weaponize a single endpoint into full‑stack compromise. AI‑powered scanners magnify the risk—probing millions of routes per hour and automating exploit development faster than your team can patch.
How We Solve It
Certified testers decompile Swagger/OpenAPI specs, reverse‑engineer undocumented calls, and fuzz every parameter with dynamic and static analyzers. We chain vulnerabilities—Broken Object Level Authorization, mass assignment, injection—to simulate real‑world data theft. Each finding is ranked by CVSS, business impact, and mapped to mitigating OWASP controls, then pushed into Jira or ServiceNow for instant tracking.
The Outcome
70%
fewer exploitable endpoints after first remediation sprint.
<24 h
mean time‑to‑verify fixes via complimentary re‑test.
Zero
critical OWASP API Top 10 gaps in 90‑day follow‑up audit.
Key Security Tests
Authentication
Verify tokens, MFA flows, and OAuth/OIDC scopes to block stolen‑credential replay and brute‑force abuse.
Error Handling
Trigger verbose errors to harvest stack traces, internal IPs, and dependency versions for recon weaponization.
Authorization
Exploit BOLA/BOPLA to access cross‑tenant data, privilege‑escalate roles, and inject forged object IDs.
Logging & Monitoring
Confirm API gateways emit structured logs and raise real‑time alerts on anomalous spikes.
Session Management
Inspect cookie flags, rotation intervals, and refresh‑token revocation to prevent session hijacking.
Encryption
Assess TLS configs, certificate pinning, and payload encryption to stop MITM and replay attacks.
Data Validation
Fuzz path, query, and JSON bodies for injection, XXL payloads, and deserialization attacks.
