Secure Email Certificates

Publically trusted secure email certificates

Also known as S/MIME (Secure / Multipurpose Internet Mail Extensions) Certificates, Secure Email Certificates provide the strongest levels of confidentiality and security for your electronic communications.

Entrust Secure Email Certificates allows you to digitally sign and encrypt your mail and attachments. Encryption means that only your intended recipient will be able to read message, while digitally signing it allows them to confirm and verify that you sent the message and it was not tampered with.
