Secure/Multipurpose Internet Mail Extensions (S/MIME) is a standard for digital signature and public-key encryption of all kinds of data.
Digital signatures authenticate your identity and prevent tampering. This gives your recipients confidence that the email came from you and that the email’s content has not been altered in transit.
Email encryption keeps sensitive information from falling into the wrong hands. With S/MIME encryption, only the intended recipient can access the contents of your email.
Emails are not as private as you think
Did you know that the emails you send and receive through Gmail or Outlook are easy to read and manipulate? At least to hackers who know what they are doing.
Emails are bounced around through a series of servers and across the internet. Without encryption combined with a means to verify the sender and the integrity of the data, your emails are not secure. This can put you and your company at risk.
Advanced email security and fraud protection
Malicious parties have become increasingly sophisticated at targeting organizations via email.
Their methods include intercepting messages to view sensitive information and email spoofing with the intent of pushing users to phishing sites or triggering malware downloads.
With a PersonalSign S/MIME certificate, you can digitally sign and encrypt emails and ensure only intended recipients can access email content. It’s easy to verify the origin of an email, and you shut out malicious parties.
In essence, total email security.
End-to-End Encryption (E2EE)
Unlike virtually other “secure email” solutions, email certificates offer real end-to-end encryption.
Security professionals and privacy experts largely agree that end-to-end encryption is superior when protecting your data from hackers and other parties who may want to spy on you.
When you allow the data transmitter – your existing email service provider – to decrypt your messages, you’re leaving a significant potential security hole that could cause problems if the server is compromised.
