Encrypted Cloud Storage and File Sharing

Trust Nothing. Encrypt Everything. Keep The Key.

CipherLocker™ is the first encrypted file sharing, storage, and collaboration platform with a search portal on encrypted data and strong client-side data encryption. You can drag-and-drop, store, share, synchronize, and search. The cloud cannot ever access user data or searches even when compelled. Files are encrypted before they leave your computer.
