Desktop security software built for privacy
Sharp#Soft protects your files, messages, and identity on Windows, macOS, and Linux — for individuals and organisations of any size. Built so that no one can read what's yours. Not an intruder, not our servers — not even us.
Private by design, not by promise.
Only you hold the keys
The keys to your data are created on your device and never leave it — not even to us. Nothing opens without the credential you keep. There's no master key and no back door, because none can exist.
Your files and messages stay yours
Documents, files, and messages are sealed so only the people you choose can open them — whether they live on your device or in the cloud. No admin override, no support team that can peek, no "trust us."
Even who you talk to stays private
Outsiders can't read your messages — or even see who you're talking to, how often, or how much. All anyone watching the network sees is sealed envelopes.
