Your AI is live.
Is it safe?

Hyperfence blocks attacks, enforces your rules, and shows you exactly what users are asking. Ship with confidence, not hope.

Hyperfence uses deterministic methods to move your AI from "probably safe" to provably safe.

Users will try to manipulate your AI

Prompt injection is the most common attack on generative AI. Users craft messages designed to override your instructions, extract private data, or make your bot say things it should not. This is not theoretical. It happens daily in live products.

Prompt injection blocked before it reaches your model Jailbreak attempts caught on every message Works even when attacks are disguised or rephrased

Every business has topics its AI should not discuss

A customer service bot discussing competitor pricing. A support bot getting drawn into political debates. A retail assistant giving medical advice. Generic content filters cannot reflect your specific rules. Custom vector Hyperfences let you define exactly what is in and out of bounds using plain examples, not code.

Define allowed and blocked topics specific to your business Rules hold even when users rephrase or try different languages No ML expertise required - give examples, we handle the rest

What your LLMs or agents say can affect your brand

LLMs can still surprise you. A bot that generates harmful, offensive, or completely off-brand content, even once, creates reputational and legal risk.

Relying on the model to police itself is not enough, and adding a second AI to check the first is expensive and slow.

Built-in rules: profanity, adult content, hate speech, self-harm Checks both what users send and what your model replies No second LLM. Purpose-built classifiers with under 200 ms latency

Works with your existing setup

Hyperfence is a transparent proxy. It sits between your app and your LLM provider. You simply change the base URL and add your token. That's it. No SDK to integrate, no code changes, and no redeployment of your chatbot logic.


It works with OpenAI, Anthropic, Gemini, and most other providers out of the box.

Full protection, zero cost.
