Due to stricter GDPR regulations, the increase in cyberattacks, and heightened awareness of data security, email encryption is now a basic requirement for companies – especially in sectors (such as tax consulting, healthcare, legal, or insurance) where sensitive information is regularly sent via email. However, traditional S/MIME certificates must be manually renewed and reissued annually. This results in significant administrative effort and time for IT managers – especially when many user accounts must be managed simultaneously. The efficient solution: S/MIME automation with zertmail.
Advantages and disadvantages of S/MIME at a glance
Advantages:
- Maximum security thanks to secure encryption and digital signatures.
- End-to-end protection ensures only authorized recipients can read emails.
- GDPR-compliant communication with clients, patients, or business partners.
Disadvantages of traditional administration:
- High administrative overhead due to annual renewals.
- IT administrators must manually monitor and renew certificates.
- Risk of certificate expiration and subsequent communication outages.
Secure email communication with S/MIME: What to consider
S/MIME (Secure/Multipurpose Internet Mail Extensions) is one of the most secure standards for email encryption. It ensures that messages are authenticated and protected from unauthorized access. However, the following aspects should be considered when using S/MIME:
- Every employee needs their own certificate.
- Certificates expire annually and must be renewed on time.
- Manual renewals take time and tie up IT administration resources.
- Failure to update a certificate in a timely manner can lead to communication interruptions and security vulnerabilities.
These points show that the use of S/MIME in companies should be well planned to ensure security and smooth operations.
