Google is updating Gmail to allow enterprise users to send encrypted messages to any inbox in just a few clicks. Google says it’s developed a new encryption model that, unlike the current encryption feature on Gmail, doesn’t require senders or recipients to use custom software or exchange encryption certificates.

Although the encryption is for business customers, regular consumers on both Gmail and non-Gmail accounts can receive the encrypted emails.

Google LLC today introduced a new end-to-end email encryption solution for Gmail designed to reduce the friction and complexity typically associated with secure enterprise messaging.
