Guardian of the threshold.

Kysira builds AI-powered cybersecurity infrastructure that stops web application attacks before they reach your stack. Our reverse proxy scores every HTTP request in under 40ms and kills threats at the connection level — no code changes, no new agents, one container.

We are security engineers and AI researchers who got tired of watching the same attacks top the breach charts year after year while defenders stayed stuck in reactive mode. Kysira is our answer: move the kill decision to the machine, keep it on the hot path, and get the attacker's terminal to die mid-payload.

The name comes from the Greek Kyrios (authority over) and Thyra (door, gate) — guardian of the threshold. That is exactly what we build.
