Sarus SarusLLM is a commercial ai model security tool by Sarus. Witness AI for Employees is a commercial ai model security tool by WitnessAI. Compare features, ratings, integrations, and community reviews side by side to find the best ai model 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 teams fine-tuning LLMs on sensitive data will find real value in SarusLLM's differential privacy approach, which lets data scientists build custom models without exposing raw datasets to the training process. The platform's DP-SGD implementation and zero-trust data access model directly address NIST PR.DS (Data Security) requirements that most LLM workflows ignore entirely. Skip this if your org needs to fine-tune at scale without GPU infrastructure constraints; SarusLLM's on-premises deployment and orchestration overhead make it a poor fit for teams wanting minimal operational lift.
Mid-market and enterprise security teams dealing with shadow AI sprawl should start here; Witness AI for Employees maps employee LLM usage across your org and blocks prompt injection and jailbreak attempts before they become incidents. The platform covers ID.AM and PR.AA across the NIST CSF 2.0 framework, meaning you get real asset discovery of AI tools plus enforced access controls tied to actual policy, not just detection logs. Skip this if your org hasn't yet standardized on which AI tools employees can use; you'll need that baseline before Witness can protect it.
