Real-time AI threat protection

Antivirus for
the AI era.

Your AI assistant can be turned against you. AEGIS catches the attack and stops your data from leaking, before it ever leaves your machine.

On-device scanning Nothing leaves your computer Built for AI, not retrofitted
The threat nobody else stops

A hidden instruction can hijack your AI.

Open a web page, a document or an email, and an attacker can plant invisible instructions that hijack ChatGPT, Claude or Copilot, making your own AI read your files, leak your data, or act without your consent. It's called prompt injection, and classic antivirus can't see it.

AEGIS reads what's about to be sent, catches the injection on your device, and blocks it, showing you exactly what it found.

AEGIS blocking a prompt-injection attempt
Smart, not annoying

It knows the difference between you and an attacker.

What you type stays yours, AEGIS never blocks your own words. Only instructions that arrive hidden in untrusted content (a page, a doc, a tool's output) get stopped. So you're protected without the false alarms.

Desktop App

Guards the whole machine, beyond the browser: malicious AI processes, AI-driven intrusion, and non-browser AI tools like local models and coding assistants. Needs OS-level access a browser extension can't have.
