Experts warn that emails with sensitive data are being delivered unencrypted without notification in Microsoft 365 and Google Workspace.
Microsoft 365 sends emails in plain text when encryption fails without alerting users, while Google Workspace uses insecure TLS versions without warning senders or rejecting messages.
Default email behaviors in these platforms undermine encryption, posing serious compliance risks, especially for healthcare organizations sending Protected Health Information.
Despite warnings against outdated TLS protocols, both platforms continue to expose data, risking compliance violations and potential data breaches.
