Cloudflare API Shield is a commercial api security tool by Cloudflare, Inc.. Wallarm API Security is a commercial api security tool by Wallarm. 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:
Mid-market and enterprise security teams with distributed APIs will get immediate value from Cloudflare API Shield because shadow API discovery removes the guesswork about what you're actually protecting. The platform's ML-driven endpoint detection finds undocumented APIs that manual inventory never catches, and OWASP Top 10 API coverage plus schema validation enforces a positive security model without requiring teams to maintain separate API gateway tooling. Not ideal for organizations still mapping their API surface or those needing deep integration with non-Cloudflare infrastructure; you'll get the most ROI when APIs already route through Cloudflare's network.
Mid-market and enterprise teams operating microservices architectures need API inventory and threat detection that actually works without manual specification writing, and Wallarm API Security builds that inventory automatically from live traffic while enforcing OWASP API Top 10 controls in real time. The platform covers NIST ID.AM (asset discovery), ID.RA (continuous API risk assessment), and DE.CM (anomaly detection) across your API estate, with native integrations to PagerDuty and Jira that keep findings actionable. This isn't the tool for organizations that have already locked down APIs with hardened specifications and rarely deploy new endpoints; Wallarm's automation advantage disappears when your API surface is static and well-documented.
