Changelog

Hyperfence now catches more of what it should block and stops less of what it should allow.

The improvements apply automatically to every Hyperfence. There is nothing to update or redeploy.

Try Hyperfence directly in your browser now. No signup, API key, or setup required.

The demo runs a live model behind a real Hyperfence instance so you can watch inspection, analysis and enforcement happen in real time.

Hyperfence is now in open beta.

Hyperfence sits between your application and your LLM provider. It inspects every prompt and response, enforces content and security policies deterministically, and adds milliseconds of latency, removing the need for a second guard model in the loop. Integration is a simple base URL change and a token; no SDK, no changes to your existing stack.

The beta includes preset Hyperfences and full platform access, including usage and token stats and a blocked event log.
