CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams deploying multiple LLM models across production workloads need CloudMatos Prompt Firewall to stop prompt injection and data exfiltration at inference time, not after the fact. The tool's zero-trust prompt filtering and real-time jailbreak signature detection address DE.CM and DE.AE functions that most guardrails treat as afterthoughts, while multi-model compatibility means you're not locked into OpenAI. Skip this if your LLM use is experimental or limited to a single vendor's API; the policy enforcement overhead assumes mature, compliance-driven deployments where audit trails matter as much as blocking attacks.
Teams deploying LLMs into production at scale need DeepKeep LLM because it catches prompt injection and data leakage simultaneously, which matters when a single misconfigured model can expose customer PII to attackers in seconds. The platform covers all four NIST CSF 2.0 Detect and Protect functions and supports vision and multimodal models alongside text LLMs, addressing the messy reality of modern AI stacks. Skip this if your LLM use case is narrow and internal; DeepKeep's value compounds with deployment complexity.
