Advanced encryption and security for M365

When email became the standard form of communication in business, government, and for stakeholder interactions, security wasn’t a priority. Today, with data protection regulations growing and evolving, organizations need to be absolutely sure their emails are protected. We’ve got you covered.

Zero-Knowledge Encryption

Many secure email providers hold the encryption keys to client data and messages. This means that data could be accessible to third parties. We don’t hold the keys to client messages, ensuring the only people who can access emails are the sender and recipient.

Two-Factor Authentication

Messages sent securely with Zivver require two-factor authentication via an SMS, an access code, or a one-click access link. 2FA controls ensure only the right people can access secure messages.
