Compare features, ratings, integrations, and community reviews side by side to find the best api security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Contrast Application Detection and Response (ADR)
Security teams protecting APIs and microservices in production will get the most from Contrast Application Detection and Response because it detects and blocks exploits in real time at the code level, which means you stop attacks without waiting for patches. The tool's continuous vulnerability monitoring combined with inline blocking addresses the gap most organizations face between detection and response, covering NIST DE.CM through RS.MI. Skip this if you need broad infrastructure visibility beyond applications; Contrast is application-focused and won't replace your CNAPP or network detection layer.
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.
