Secure Email - Digitally Sign & Encrypt Emails

GlobalSign PersonalSign Certificates use S/MIME technology to allow users to digitally sign and encrypt email.

Digitally signing an email proves authorship and prevents tampering, assuring the email recipient that the email came from you, not an imposter, and that the content of the email has not been altered in transit.

Encrypting email ensures message privacy and keeps sensitive information from falling into the wrong hands. With S/MIME encryption, only the intended recipient can access email contents.

Secure Email is achieved using GlobalSign's Digital Certificate solution called PersonalSign. PersonalSign Certificates are cryptographic signing certificates that bind your verified, physical identity to the certificate so recipients of email messages can verify that the email actually came from you.

How it Works - Using the S/MIME Protocol

GlobalSign's PersonalSign Certificates employ the Secure/Multipurpose Internet Mail Extensions (S/MIME) protocol to digitally sign or encrypt emails. S/MIME Encryption provides message integrity, authentication, privacy via data encryption, and non-repudiation via digital signatures.

Most mail clients support S/MIME, such as Microsoft Outlook, Thunderbird, Apple Mail, Lotus Notes, and Mulberry Mail. For most clients, digitally signing and/or encrypting an email is as simple as clicking a button. Many clients also offer the option to automatically do this for all outgoing messages. For more information on how S/MIME works, please see our introductory eBook Email Security Using Digital Signatures & Encryption.
