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.

One view, total visibility

Aggregate sessions → traces → spans in a single, filterable view. 

Scan thousands of calls with instant cues, “Good,” “Triggered,” or “Timeout,” and see the exact rule that fired, the action taken, and the average latency in real time. Click any row to pivot deeper or export the evidence for audits.

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.
