What is an Email Security Certificate (S/MIME) and how does it protect my emails?
An S/MIME certificate encrypts your emails and digitally signs them to verify the sender’s identity. It confirms that your messages can’t be interrupted, changed, or imitated during transmission.
Why should my business use S/MIME signing and encryption instead of relying on standard email security?
While regular email security protects the connection, S/MIME adds end-to-end encryption and digital identity verification, safeguarding sensitive information, and preventing phishing or impersonation attacks.
