SMIME

QuanTrustPKI integrates seamlessly with Secure/Multipurpose Internet Mail Extensions (S/MIME) to provide end-to-end email encryption, digital signatures, and enhanced email security. S/MIME is an industry-standard protocol for securing email communications through the use of cryptographic certificates, ensuring both the authenticity and confidentiality of email messages. With QuanTrustPKI’s integration, organizations can easily deploy S/MIME certificates, enabling their employees to sign and encrypt emails effortlessly, thus safeguarding sensitive information from unauthorized access and tampering.

This integration ensures that all email communications are cryptographically protected, with digital signatures verifying the sender’s identity and email content, and encryption ensuring that only intended recipients can read the message. The solution is fully compliant with global security standards, including X.509 certificates, and supports integration with major email clients like Microsoft Outlook, Apple Mail, and others, allowing for smooth deployment across various platforms.

S/MIME Use Cases

This messaging standard inherently supports many functions that enhance and secure emails. It can be used to:

  • Create digital signatures (also known as “non-repudiation of origin”)
  • Ensure message privacy
  • Encrypt messages
  • Authenticate to the web client
  • Ensure “message integrity” (to confirm the message hasn’t been altered)

The most obvious implementation of S/MIME is as a stronger form of email encryption, but when used to its full extent, it provides critical services that go beyond simple encryption and help protect you from social engineering attacks too.

Why is S/MIME Important?

If you’re not enamored by the mere idea of using ultra-secure certificates anywhere that will support them, we’ll give you a couple reasons why you actually do need S/MIME protecting your emails.

S/MIME Prevents Phishing Attacks

A very common method of phishing is to send fraudulent emails that trick the recipient into performing a task, usually to send money or pass on credentials.
