DekkoCORE is a more Efficient Way to Share Securely

When you’re sharing sensitive information, encrypting a file yourself and relying on the recipient to handle decryption might seem safe enough. But imagine repeating that process with dozens of users, hundreds of files and no central visibility or control. It quickly becomes risky, inconsistent and unmanageable!

DekkoCORE is a fully end-to-end encrypted file sharing and collaboration platform that handles all of this for you.

Fast, automated encryption with zero user training

Share with externals without exposing your systems

Share, sign, message and collaborate in one app
