Compare EncryptPro vs. Proton Drive

Right-click a file to encrypt it for yourself, or for someone you're sharing it with — same menu, same two clicks. Shared files carry no password, no key management, and no email addresses — so the channel you share it over doesn't matter. Windows encryption with no containers, vaults, or drives to mount. Encrypt any file type. Double-click to open and edit it in its native application — changes save straight back to encrypted. Streaming decryption means a 10GB video plays within seconds while the rest decrypts in the background — no extract, no wait, no re-compress. Files stay where they are. Originals are overwritten with zeros, then random data, across multiple passes before deletion — unrecoverable even to forensic tools. Security groups organize encrypted files under separate passwords, so you unlock only what you're working on. Explorer icons show group and lock state at a glance, even when EncryptPro isn't running. Sharing runs on PGP-style key pairs generated once per connection. Keys never travel with the file — email it, put it on a public link, it makes no difference. C2 connections give teams one encrypt operation and universal member access, with no per-recipient steps. Only the creator needs a paid plan, so an entire team runs on one subscription. Keys derive from a master password we never receive, so your data is unreadable to us. There is no password recovery — any vendor offering account recovery necessarily holds something recoverable. We hold nothing readable. You can't be locked out of your data. Viewer Only Mode authenticates offline against your device. Expired subscription, no internet, our servers down, the company gone — your encrypted files still open. Windows only. Free version permanent, no credit card. Paid from $4/month.
