CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams managing API sprawl across multiple gateways should buy Imperva API Security for its agentless shadow API discovery, which catches undocumented endpoints that application teams hide in production. The platform scores strongest on ID.AM and DE.CM (asset discovery and continuous monitoring), mapping every API and flagging anomalies without requiring agents on every gateway. Skip this if you need shift-left scanning to block vulnerabilities before deployment; Imperva's testing capability exists but isn't its competitive edge against dedicated SAST tools.
Teams managing APIs at scale across multiple regions need Fastly API Security because it discovers and protects undocumented APIs in real time at the edge, catching shadow APIs before they become breach vectors. The platform covers all six OWASP Top 10 API risks and integrates DDoS and bot mitigation without requiring separate tools, reducing alert fatigue from fragmented stacks. Skip this if you're looking for API governance and compliance workflow automation; Fastly excels at runtime detection and threat response, not policy enforcement or change management.
