REAL-TIME CONTROL FOR AI APPLICATIONS

The semantic firewall for AI

Businesses have rules. AI doesn’t know what they are.
Moonbounce sits between your AI, your users, and the real world and decides — in real time — what’s allowed.

Businesses have rules.
Models don’t know what they are.

FINANCIAL AGENT

No personalized investment advice without a suitability check. No tax advice without disclosure.

INTERNAL ASSISTANT

No salary data to non-managers, no M&A material outside the deal team.

SUPPORT AGENT

No refunds without appropriate cause. No commitments the company hasn’t approved.

DATING APP

No soliciting payment, no off-platform contact push, no harassment in an opener.

Moonbounce turns the rules you already have into real-time controls.

ONE FIREWALL AROUND EVERY EXCHANGE

Understand. Decide. Enforce.

THE SURFACE

Every exchange your AI has — with a user, a document, a tool, another system. Prompts, outputs, and tool calls, whether that means text, image, audio, or video.

THE DECISION

What the content and the action actually mean, judged against your policy — not keywords, not the model provider’s rules.

THE ENFORCEMENT

Inline, in under 300ms: allow, block, rewrite, escalate, or label — before the output reaches a user or the action executes.

REWRITE

Don’t just block—transform an off-policy output so it complies and then let the interaction continue.

DECISION MEMORY

Better with every decision

DEFINE

→

DEPLOY

→

CORRECT

→

IMPROVE

Moonbounce isn’t a static classifier. Every correction your team makes — and the reason behind it — is kept as precedent, so enforcement bends toward your judgment and keeps improving. How the loop works →

What is a semantic firewall?

–

A policy engine that sits between your AI and the real world, reasoning over the meaning and intent of every prompt, output, and tool call — and deciding, against your policy, whether it’s allowed. Read the full explainer on our Semantic Firewall page.
