Best for	Security teams needing continuously updated, model-agnostic runtime protection for GenAI apps	Developers building conversational LLM apps who need programmable dialog rails and topic control
Limitations	Now part of Check Point, so roadmap and packaging may shift toward that portfolio; focused on security rather than broad GRC/compliance workflow tooling	Colang has a learning curve; primarily developer-facing with limited built-in GRC/compliance reporting; best value realized within the broader NVIDIA ecosystem

Which should you shortlist?

Choose Lakera if security teams needing continuously updated, model-agnostic runtime protection for GenAI apps

Choose NVIDIA NeMo Guardrails if developers building conversational LLM apps who need programmable dialog rails and topic control

Neither is a substitute for a governance program. Whichever you pick, you still need people who can define the policies the tool enforces.
