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.

Just days after Google confirmed it is bringing its next AI upgrade to Gmail, with major privacy implications, there’s more good and bad news for the 3 billion users relying on Google to deliver secure, spam-free email to their phones and computers. It turns out that a dangerous email attack has operated under the radar for years — until now.
