Antivirus for
the AI era.
Your AI assistant can be turned against you. AEGISITE catches the attack and stops your data from leaking, before it ever leaves your machine.
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.
AEGISITE reads what's about to be sent, catches the injection on your device, and blocks it, showing you exactly what it found.
It knows the difference between you and an attacker.
What you type stays yours, AEGISITE 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.
