StackHawk API Discovery vs TeejLab API Discovery Manager: Side-by-Side Comparison (2026)

StackHawk API Discovery

Platform and product security teams managing microservices across multiple repositories need StackHawk API Discovery to stop shipping undocumented APIs into production; it's the only tool that maps your attack surface directly from code commits and flags shadow endpoints before they become breach vectors. The AI-generated OpenAPI specs and continuous inventory updates mean your API catalog stays in sync with actual deployments, which NIST ID.AM asset management requires but most teams skip entirely. Skip this if your APIs are mostly monolithic REST services behind a single gateway,you'll pay for microservices and serverless detection you don't need.

TeejLab API Discovery Manager

Mid-market and enterprise security teams drowning in shadow APIs and undocumented integrations should start with TeejLab API Discovery Manager because it finds what you don't know exists through repository scanning and network traffic analysis, then maps compliance gaps against actual API behavior. The platform covers NIST ID.AM and ID.RA thoroughly, giving you the asset inventory and risk visibility needed before you can govern, plus it integrates directly into CI/CD pipelines so discovery happens continuously, not as a quarterly audit exercise. Skip this if your API surface is small or your APIs are predominantly third-party managed; the value compounds only when you have dozens of internal and inherited services that nobody fully owns.
