CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams deploying large language models or AI agents in production need DeepKeep AI Firewall to prevent prompt injection and policy violations at runtime, where traditional API gateways fail to inspect semantic content. The tool covers three NIST CSF 2.0 functions,Platform Security, Continuous Monitoring, and Adverse Event Analysis,with particular strength in real-time content redaction and custom policy enforcement across hybrid cloud setups. Skip this if your primary concern is securing third-party AI APIs rather than your own AI systems; DeepKeep is built for organizations running their own models.
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.
