Arcjet is a commercial api security tool by Arcjet. Cequence API Security is a commercial api security tool by Cequence Security. Compare features, ratings, integrations, and community reviews side by side to find the best api security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Developers building APIs and web services need bot and rate-limit protection that doesn't require security expertise to deploy, and Arcjet's SDK-first approach means you configure rules in code rather than wrestling with WAF consoles. The WebAssembly-based local execution runs decisions at the edge without sending traffic to external services, cutting latency and keeping you compliant with data residency constraints. Skip this if your primary concern is legacy OWASP Top 10 coverage on existing monolithic applications; Arcjet is built for modern application stacks, not retrofitting old infrastructure.
Teams managing sprawling API ecosystems without visibility into shadow or third-party APIs should start with Cequence API Security; its automated discovery and ML-based risk categorization catches what manual inventories miss, and native integration with CI/CD pipelines means you can shift left without rearchitecting your pipeline. The platform maps to NIST ID.AM and DE.CM, giving you both asset visibility and continuous monitoring from day one. Skip this if your organization has fewer than 50 APIs or you need a WAF replacement; Cequence assumes you're already past the "do we have APIs" phase and moving toward "which ones are actually exposed.
