Zero Trust Security

Data is protected even when servers, admins and passwords are breached.

All data is secured using end-to-end encryption, which means that the information is only ever encrypted and decrypted on a user’s device -never on the server. In addition, cryptographic techniques ensure that data cannot be accessed with stolen passwords nor by using a compromised administrator’s credentials.
