Improve the security of your S/MIME usage

S/MIME (Secure/Multipurpose Internet Mail Extensions) is a universal standard for securely signing and encrypting email to help protect information and maintain privacy.

Allowing the encryption of an email’s content provides proof that the email was authenticated as coming from the authorized source.

S/MIME security risks

Identity validation is always part of a message sent using S/MIME, whereas message encryption is optional. Because message encryption is voluntary, there is the potential for sensitive information within emails to be leaked.

How can Keyfactor help ensure S/MIME security?

  • Issue certificates to users on Windows, Windows Phone, iOS, Mac, Android, and Linux devices
