Missing role-based access controls
Key endpoints lacked privilege checks, allowing operations that should have been restricted to elevated roles.
Case Study / API security assessment
300+ APIs, one structured assessment
An enterprise survey platform runs its core services across more than 300 APIs spanning multiple microservices. The API estate had grown without a formal security review — sensitive data volume had not. We were engaged to assess the full surface.
Enterprise SaaS platform · 300+ APIs
What we found
Weak input validation
Parameter validation was thin across endpoint groups, creating injection and data-manipulation risk.
Internal API exposure
Frontend JavaScript unintentionally disclosed private endpoints — expanding the reachable attack surface beyond anything documented.
Ungoverned API sprawl
With 300+ endpoints across microservices and no security testing history, no one could say with confidence what was exposed.
How we worked
Complete endpoint discovery
Systematic mapping of all 300+ APIs — documented and undocumented — including relationships and access patterns between services.
OWASP API Security Top 10
Assessment structured against the OWASP API Top 10, covering authorization, authentication, injection, and resource-abuse classes.
Hybrid testing
Manual testing, open-source tooling, and custom scripts — the combination needed to find both misconfigurations and deep logic flaws.
Chained exploit demonstration
Real attack paths shown end to end — e.g., a public API leak escalating into broken authorization — so priorities set themselves.
What changed
- The client received a prioritized, developer-ready remediation guide with code-level examples.
- Knowledge-transfer workshops raised the engineering team's API-security baseline.
- The platform gained its first complete, security-reviewed API inventory.
Client identity is confidential by agreement. Findings are published with the client’s engagement anonymized; we never publish metrics we didn’t measure.
