Secure Email - Digitally Sign and Encrypt Emails

Individual Certificates

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.

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.

Digitally Signed Email:
Proves authorship & prevent tampering
Encrypted Email:

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.
