Beta · Now live · May 2026
Today we’re opening Hyperfence Beta to teams building the next generation of AI products.
Every team shipping AI is one bad prompt away from a serious incident. Prompt injection, jailbreaks, off-topic abuse, and token cost overruns are not theoretical risks. They are production problems that happen every day, and the tools to prevent them have too often been too slow, too inaccurate, and too expensive.
That’s what Hyperfence is here to fix.
Hyperfence is a real-time AI safety layer that sits between your application and your LLM. It classifies and blocks harmful, off-topic, or malicious inputs before they ever reach the model. With sub-200 ms latency, it is effectively invisible to your users.
What makes Hyperfence different?
Unlike guardrail products that rely on a second AI model to judge the first, Hyperfence uses a deterministic vector geofencing approach. Mathematical vector boundaries classify inputs precisely, without hallucination risk, added model cost, or probabilistic guesswork.
The result is a security guarantee rather than a security estimate.
- Blocks prompt injection, jailbreaks, and off-topic queries in real time
- Full analytics dashboard including usage patterns, topic drift, injection attempts, token savings
- Zero data retention - inputs are never written to disk, never stored, never accessible after classification
- Simple, fast, affordable proxy layer that works with OpenAI, Anthropic, Gemini, Perplexity, DeepSeek, and more
Free core protection starts now
We’re launching in beta, and free accounts are live right now. We want developers to get hands-on, try it out, and tell us what matters. Beta users will shape what Hyperfence becomes, and your feedback will be invaluable.
Sign up, integrate in minutes, and start seeing exactly what’s hitting your AI in production and what we’re stopping for you.
Coming soon
We have a lot more in the pipeline, and we’ll be shipping quickly, including Custom Hyperfences with topic boundaries tailored to your environment.
Watch this space… the next few months are going to be busy.
