Benefits of Sectigo S/MIME Email Certificates


Email Signing

Verify emails came from the intended sender to protect your business against phishing, malware, and business email compromise (BEC). Prevent data breaches of sensitive information by detecting if the webmail or attachments were modified after the digital signature/digital id.

Email Encryption

Enable end-to-end encryption for email messages and attachments between you and your intended recipients. Encrypted messages cannot be intercepted and decrypted by man-in-the-middle attackers, packet-sniffers, or https proxies.

Regulatory Compliance

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