Lakera Guard
Depot pick for a dedicated prompt-injection firewall in front of any LLM. NeMo when you need programmable rails; OpenAI Moderation for free taxonomy flags. Check Point acquisition is real — product still has a public API. Strengths: Purpose-built prompt-injection / jailbreak / leakage API with sub-50ms narrative; Real
Strengths

- Real free Community tier for eval
- EU-native residency on the free plan
Weaknesses
- Paid SKU is sales-gated (no Pro list price)
- Post-Check Point packaging/quote path may slow indie procurement
- Not a full policy engine like NeMo Guardrails
NVIDIA NeMo Guardrails
When OpenAI Moderation taxonomy is not enough and you need programmable rails. Host Llama Guard on Groq for the cheap classifier leaf. Strengths: Programmable Colang/rails policy engine; Composes with Llama Guard / NIM models; Serious production guardrail toolkit.
Strengths
- Programmable Colang/rails policy engine
- Composes with Llama Guard / NIM models
- Serious production guardrail toolkit
Weaknesses
- Ops-heavy vs free OpenAI Moderation
- DX steeper than drop-in classifiers
- Hosted packaging split across NIM/microservices
