Protect
Real-time hallucination & threat firewall
Stop prompt attacks, data leaks, and hallucinations in
< 200ms, powered by Luna-2.
Catch failures before users do
AI systems can misbehave at any step, leaking PII, hallucinating answers, or accepting hostile prompts. Still, most teams rely on DIY feature flags or heavyweight LLM judges that are too slow and expensive for real-time use.
Protect gives you an enterprise-grade firewall that intercepts risky inputs and outputs before damage is done.
Powered by Luna-2, Protect
Scores each input and output against advanced guardrail metrics
Blocks risky content on the fly
Lets you refine rules without redeploying code

How Protect works
Configure rulesets
Define metrics and actions either in code or the UI.
Monitor & alert
Live dashboards surface every trigger with latency stats.
Iterate & version
Tweak rules safely; Protect keeps history and rollbacks.
After configuring your rules, Protect does everything else, turning configuration into always-on defense and rich observability, including:
Proactive Interception
Block prompt injections, toxic text, PII, and more before they hit your model.
Central Rule Management
Create, test, and version rules in a no-code UI or via API.
Action Engine
Choose what happens on breach: override, redact, or fire a webhook.
Hallucination Control
Override or redact off-brand, fabricated answers automatically.
Luna-2
Real-time protection
Our Luna-2’s SLMs are purpose-built for always-on evaluations.
Multi-headed Small Language Models evaluate 10-20 guardrail metrics at once with sub-200 ms latency and ~97 % lower cost than GPT-style judges, making always-on protection affordable at scale.
Root cause, in one click
Open a session and get a live tree of every step, including protect stages, tool calls, and LLM responses. The tree is color-coded by guardrail outcome and built with a simple interface for rapid debugging. The right panel reveals the input, guardrail config, triggered rule, and redacted or overridden output, plus system metrics like latency.
