Emails pass through many different computer systems without your knowledge. Formidable CA Personal Certificates let you sign your email digitally to prove that the message and attachments actually came from you.



Non-encrypted emails can be easily intercepted and read by someone without your authority. Others can even snoop on your email Inbox, or intercept messages, as you check your mail wirelessly on your laptop or mobile phone. Formidable CA Personal Certificates allow you to encrypt your email easily and ensure that the messages and attachments can only be read by the intended recipients.




Regular, unsecured email can easily be faked and messages can be produced and distributed that look like they were prepared and sent by you when the truth is that you may never know anything about them. By digitally signing your emails with a Personal Certificate, no-one else can alter the contents of your mail without the recipient being alerted.




Formidable CA Personal Certificates are fully trusted by 99% of email clients including:


  • Microsoft® Outlook Express
  • Microsoft® Outlook®
  • Microsoft® Entourage
  • Apple Mail
  • Mozilla Thunderbird
  • Or any other S/MIME compliant software


You have a right to expect that no-one is reading your mail or using your identity and your contacts and clients quite reasonably expect that no-one else is reading emails (and attachments) meant for them nor accessing the often sensitive information therein.
