Cyphora is building the prevention layer that the security industry has been missing. Not detection. Not response. Prevention by design.
The security industry has spent decades building better detection. Better signatures. Better heuristics. Better AI models. And yet ransomware attacks keep increasing — faster, stealthier, and more destructive every year.
The problem isn't that detection isn't good enough. The problem is that detection is the wrong strategy. When ransomware can encrypt files in minutes and info-stealers exfiltrate data silently, reacting to an alert — even an instant one — is already too late.
Cyphora takes a fundamentally different approach. Instead of asking "is this process malicious?" we ask "is this application trusted to access these files?" It's the difference between trying to spot every possible thief and simply keeping valuables where thieves can't reach them.

If you discover a security vulnerability in Cyphora's products, please report it to us through our coordinated disclosure program.
Your encryption keys are derived and stored locally. Our servers store only encrypted blobs we cannot decrypt. Even if our infrastructure is compromised, your data is meaningless ciphertext.
We collect minimal data — only what's necessary to provide the service. No behavioral tracking, no usage analytics beyond what's needed for license enforcement, and no data resale. Ever.
Core protection works entirely offline. The kernel driver and encryption engine need no internet connection. Your files stay protected whether you're online, offline, or the server is unreachable.
We use battle-tested, open cryptographic primitives: authenticated encryption for files, BIP39 for recovery phrases, HKDF for key derivation, and scrypt for password hashing.
