Built for when "basic" isn't enough
Free protection is good at stopping known threats. The hard part is everything in between: the odd process, the file that isn't on any list yet, the alert nobody understands. That's where CitadelFrame is focused.
AI-assisted analysis
Suspicious files and behaviour are analysed using scan and behaviour details and file hashes, to separate real threats from noise.
Plain-language answers
Instead of a cryptic alert, you get what was found, how sure we are, and what to do next.
Reports to your IT team
For managed businesses, a limited security status goes to CitadelGate so your IT provider can act on it.
Protection health
Checks that every layer of Windows protection is working, not just switched on.
Privacy first
File hashes and metadata, never your file contents. No remote control through Frame.
Made for Windows
Designed for Windows laptops and desktops, at home and at work.
