Cyphora cryptographically binds your files to trusted apps. Ransomware and info-stealers can run — but your files remain ciphertext. They can't encrypt what they can't write to, and they can't steal what they can't read.
Modern threats don't just encrypt your files — they steal them too. And they're getting faster.
Attackers steal your data before encrypting it, then threaten to leak it publicly. Backups don't undo a data breach.
Info-stealer malware silently exfiltrates credentials, session tokens, crypto wallets, and sensitive files. You may never know it ran.
Encryption finishes in minutes. By the time your EDR alerts you, your files are already gone — or your data has already been exfiltrated.
Restoring from backup doesn't undo a leak. If attackers exfiltrated your client files, legal documents, or private keys, the damage is done.
Instead of trying to identify every possible threat, Cyphora ensures only trusted apps can ever see your files.
Select the applications you use to create and edit files — Photoshop, Blender, VS Code, Office, and more.
Files created by sealed apps are transparently encrypted. The apps work normally. Everything else sees ciphertext.
Ransomware and info-stealers can run on your machine, but your files are ciphertext. The kernel driver blocks writes from untrusted apps, so ransomware can't encrypt files for ransom. And exfiltrated ciphertext is useless — no data breach.
Each file is encrypted independently with its own authenticated encryption context. A kernel mini-filter redirects protected I/O to a user-mode encryption engine that encrypts before data touches disk and decrypts transparently on read. Apps see plaintext; the filesystem stores only ciphertext.
Most cloud services hold the keys to your data — which means they can access it, and anyone who compromises their servers can too. Cyphora takes the opposite approach: your encryption keys never leave your device. No third party — not Cyphora, not anyone with access to our servers — can decrypt your files. Nothing stored on our infrastructure is sufficient to unlock your data.
Sealed applications run inside a hardened execution boundary that blocks unauthorized code and module loading. Child-process and script abuse controls prevent sealed apps from being hijacked.
Run any app in two modes at once: a regular instance for everyday use and a sealed instance where everything you create is encrypted and protected. For example, use Edge for everyday browsing while a sealed Edge handles crypto transactions — both running side by side on the same desktop. Lock files, temp paths, and configs stay isolated so they never collide.
Whether you're an artist, a trader, a researcher, or a team lead — your work deserves to survive.
Protect client work, portfolios, and asset libraries. Whether you're a designer, video editor, or YouTube/TikTok creator, your content is your livelihood — keep it safe from ransomware and info-stealers.
Secure wallets, transaction signing, and private keys. Stop clipboard hijackers and info-stealers from intercepting your assets.
Shield research, legal documents, and confidential reports. Your intellectual property is ciphertext to everyone except the apps you trust.
Shared encrypted workspaces with policy enforcement and audit logs. Collaboration without compromise.
Ransomware needs to encrypt your files. Info-stealers need to read them. Cyphora blocks both.
No account required for basic protection. Download, seal your first app, and your files are safe. It's that simple.
