Email Signing and Encryption Certificates

Automate email security‎ and put a stop to hackers and phishing scams

Secure your corporate email accounts by digitally signing and encrypting communications with Sectigo S/MIME email certificates.

Email under attack

Posing as legitimate employees, servers or devices, hackers can utilize email to infiltrate an organization’s digital infrastructure and wreak havoc on its business, potentially resulting in:

  • Customer data breaches
  • Theft of intellectual property
  • Capital theft
  • Brand reputation damage

S/MIME (Secure/Multipurpose internet Mail Extensions) email certificates validate the digital identity of the user and encrypt and decrypt emails and attachments. Sectigo's secure enterprise email certificates are supported by all the major email providers and mail applications, including Microsoft Outlook on the web (Outlook 365), Exchange, Gmail, popular mobile operating systems, and more.

Benefits of Sectigo enterprise S/MIME email certificates

Email signing

With S/MIME certificates, you can verify that emails and signed messages came from the intended sender and protect your business against phishing, malware, and business email compromise (BEC) attacks. A digital signature authenticates the sender and allows you to detect any modification to the email content or attachments after it’s been signed.

Email encryption

Secure email communications by enabling end-to-end encryption for email messages and attachments between you and your intended recipients. Any encrypted email cannot be intercepted and decrypted by man-in-the-middle attacks, packet-sniffers, or https proxies.

Regulatory compliance

Secure email certificates help your organization remain compliant with security and privacy requirements, including GDPR, HIPAA, DFARS, NIST & ITAR, and other U.S. federal regulations.

CA/Browser Forum compliant S/MIME certificates

All Sectigo’s S/MIME certificates are compliant with industry standards, and in accordance with the latest Certification Authority Browser Forum (CA/Browser Forum) rules. By making sure we always meet the CA/Browser Forum’s requirements, we help our customers remain compliant themselves, and it also means that our certificates are interoperable with 3rd party systems and popular email tools.

Microsoft Intune deployment

Many organizations use Microsoft Intune to manage the mobile devices and apps their employees use to securely access data and resources. Issuing digital certificates to those mobile devices provides additional protection from unauthorized access of critical business systems through Wi-Fi, VPN, and email clients. Furthermore, certificates offer a better, more secure experience for employees with seamless authentication and can replace cumbersome passwords and multi-factor authentication (MFA).

From a single dashboard, Sectigo Certificate Manager seamlessly provisions S/MIME certificates to InTune and installs them on the employees’ mobile devices. This platform then automates the entire certificate lifecycle, from issuance to renewal.

Private key backup for S/MIME

Sectigo offers a modern Key Vault service, which helps customers store their S/MIME private keys and retrieve them as and when needed. This is particularly helpful when trying to get access to old emails when the private key has been lost, or when an employee has left the organization.
