Personal Authentication Certificates are a 3-in-1 solution that provide the following benefits:

Private and secure email

Personal Authentication Certificates provide true 'end-to-end' message encryption between you and your contacts. Signed and encrypted mail cannot be intercepted and decrypted by man-in-the-middle attackers, packet-sniffers or https proxies.

Digitally Sign Email

Authenticate yourself as the sender and make it impossible for anyone to alter its contents without alerting your recipient.

Encrypt Email

Guarantee privacy by ensuring your message cannot be intercepted and read by anybody except the intended recipients.

Digital Signature Email Encryption

Digitally sign office documents

Personal Authentication certificates allow you to sign important documents to prove they have not been tampered with since they were signed.

  • Attests to identity of document signer and proves authenticity and integrity
  • Can be used in tandem with or to replace the visible signature feature in Microsoft® Office products
  • Ensure compliance with industry directives and policy frameworks which require digitally signed documents
  • Migrate from ink and paper workflows on items like contracts, document sign-off, archiving and internal request forms

Digital Sign

Authenticate who logs into your website

Personal authentication certificates allow businesses to set up bank-standard two-factor authentication of users that login to their websites.

Once installed on a computer or mobile device, the certificate will be seamlessly requested and verified by your web-server before a user is allowed access to their account.

Authentication is transparent to end-users so they won't experience any disruption to their standard process of entering their username and password.
