Free IDE extension for risk-free vibe coding — keep secrets out of AI.
Comparison
Apache-2.0 · Python + Colang DSL · NVIDIA NIM / Triton ecosystem
NeMo Guardrails scripts what your bot is allowed to talk about. SoterAI decides what data and actions are allowed to move — at the input, the output, the retrieved context, and the tool call.
NVIDIA NeMo Guardrails models conversational safety as a state machine written in Colang, a purpose-built DSL. That design is excellent for dialog control: topic fencing, canned refusals, fact-checking rails, and multi-turn flow management, all tightly integrated with NVIDIA NIM and Triton. SoterAI takes the opposite approach — no DSL, no dialog authoring. It is a security control layer you drop in front of an existing app: classify the prompt, scan retrieved documents, redact secrets and Indian PII from the response, and authorize agent tool calls against a reversibility model before they execute. If your problem is 'keep the conversation on-topic', NeMo is the right shape. If your problem is 'stop injection, leakage, and rogue agent actions', SoterAI is.
NeMo Guardrails is the most capable open-source tool for scripted conversational control. Colang gives precise, auditable dialog state machines; the NVIDIA ecosystem integration (NIM, Triton) is deep; it is Apache-2.0; and it has NVIDIA's engineering weight and enterprise support behind it.

Choose SoterAI when
You have an app, a RAG pipeline, or an agent already built, and you need a security layer in front of it in an afternoon — covering injection, leakage, Indian PII, and agent action approval, with signed logs and no new language to learn.
Choose NVIDIA NeMo Guardrails when
You are building a conversational product where the exact dialog path matters, you want to declare that path explicitly and auditably, and you are already standardized on the NVIDIA inference stack.
Fire a prompt-injection or PII attack in the live playground and watch SoterAI block it in under 50ms.
