Crypho vs Eleven for Business

Crypho is an end-to-end encrypted communications service for chat, file sharing, and video conferencing. Persistent group chats include a shared file folder and are available only to invited members. The service supports encrypted calls and video calls, guest access, and apps for Android, iOS, macOS, Windows, and the web. It uses TOTP two-factor authentication, with tokens available by SMS or mobile app, and offers Norwegian BankID identification for company and customer processes. Crypho lists authenticated AES with 256-bit keys in CCM mode, El-Gamal elliptic-curve 384-bit encryption, and scrypt among its cryptographic methods. The company says user data is hosted on dedicated servers in Norway, without cloud services. The free plan is for personal use, limited to one group and files up to 3 MB. Pro costs €379 a month and allows up to 25 team members, 100 groups, and files up to 100 MB. Enterprise pricing is available by contacting Crypho; listed features include files up to 2 GB, unlimited groups, and an optional on-premise server.

Eleven for Business is encrypted group chat for small businesses that want to keep conversations off another party’s servers. It supports spaces, groups, direct messages, file sharing, reactions, replies, threads, GIF search, and link previews. Spaces also offer scheduled reminders, morning summaries, and a helper that can answer questions and build small apps. The service works in a browser and has native Mac and iPhone apps; its business page also says it runs on warehouse Android devices. Businesses can invite clients by link and remove them when a job ends without provisioning guest accounts. Messages and attachments are encrypted on devices, while the server stores and relays ciphertext it cannot read. Self-hosting is available at no charge with the same apps and features. The Free plan costs nothing and includes every feature, up to three spaces, and 1 GB of files per space. Business costs €11 a year, billed annually, and provides 11 GB of storage per person, pooled for the space.
