CST VerdictShort answer
Mid-market and enterprise security teams protecting APIs and AI services need Cequence AI Gateway because it actually stops business logic abuse and account takeover attacks that traditional WAFs let through. The platform covers ID.AM through DE.CM across NIST CSF 2.0, meaning you get both attack surface discovery and continuous behavioral monitoring in one deployment. Skip this if you're looking for a lightweight API firewall; Cequence demands mature API inventory practices and assumes you're defending high-value endpoints where behavioral fingerprinting ROI justifies the operational overhead. 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.
