⚠️ Your browser is now the biggest GenAI risk.

Every day, workers paste code, emails, and files into AI tools—right inside the browser. That data can leak, get stored, or even shared outside your company.

The fix isn’t banning AI. It’s securing how it’s used—in the browser session itself.

⚡ Your SaaS wasn’t hacked. It was impersonated via the browser.

Attackers ran clean, verified Chrome and Edge extensions for years. Millions of installs. One silent update flipped them into spyware.

Not a device attack. Not a cloud breach. Both at once. The browser sat in the middle, unseen, holding the keys.

FreePBX’s worst flaw isn’t a bug — it’s a legacy setting.

If AUTHTYPE is set to webserver, attackers can fake a login header and get admin access. From there, they can add their own user and run code on the system.

Default configs are safe. Old tweaks aren’t.
