Every deployed model is one clever prompt away from a jailbreak, and someone has to be the jailer.

The industry named the attack a jailbreak. This name is the answer.

A jailer holds the keys, watches the doors, and keeps what is dangerous contained. As LLMs ship into production, jailbreaks, prompt injection, and rogue agent behavior have become board-level risks. Jailer.ai is the rare name that states the countermeasure in one word, the layer that keeps models inside policy no matter what the prompt tries.

  • Jailbreak prevention
  • Prompt injection defense
  • LLM guardrails
  • Agent containment
  • Model red teaming
  • AI safety tooling

Jailer.ai names the layer that keeps every model inside its walls.

One keeper, every key.

Jailer is an agent noun with a single duty, containment. The industry already calls the attack a jailbreak, so the defense practically names itself. On .ai the word lands instantly with every security engineer who has watched a model slip its guardrails, and it carries a swagger that consumer security brands pay agencies to invent.

    Jailbreak is the threat, Jailer is the counter
