NeMo Guardrails + Agent Action Firewall
NVIDIA NeMo Guardrails controls LLM conversations. Agent Action Firewall controls what agents do. Combine them for comprehensive AI safety.
Conversation Safety vs Action Safety
NeMo Guardrails is excellent for keeping LLM conversations on-topic and safe. But conversations are just the beginning—what about the actions agents take?
NeMo Guardrails
“Is this conversation safe?”
- • Topic control (stay on-topic)
- • Jailbreak prevention
- • Dialogue flow management
- • Colang programming language
- • Open source (Apache 2.0)
Agent Action Firewall
“Should this action execute?”
- • Action policy enforcement
- • Human approval workflows
- • Cryptographic audit trails
- • OPA/Rego policies
- • Enterprise SaaS
The Action Gap
NeMo Guardrails can ensure your bot doesn't discuss prohibited topics. But it doesn't control what happens when the bot decides to take action.
Example: Customer Service Bot
“I can only help with account-related questions. I cannot provide medical advice.”
Bot wants to issue $5,000 refund → Requires manager approval via Slack before processing
