Email Certificates (S/MIME)

If you don’t encrypt email communications, a malicious attacker can intercept all your correspondence and make it public or blackmail you. Your business could lose clients if hackers steal and expose private data.

An email certificate prevents all these gloomy scenarios by keeping data safe and confirming the sender’s identity.

When you add a digital signature to your emails, the recipient can verify that the email came from you, not a phisher pretending to be you. Secure email converts the plain text data into an indecipherable string of characters, allowing only the recipient to access it.

Similarly to SSL certificates, encrypted emails use asymmetric encryption to protect the content and attachments. The sender encodes the email with a public key, while the recipient decodes the message with the matching private key.

When you hit “send” in your Microsoft Outlook or any other email client, a S/MIME certificate applies the digital signature to verify your identity and encrypts the plaintext, including any attachments. The secure email goes from your server to the recipient via the Internet. Once it arrives at the intended destination, the encrypted email is automatically decrypted with its matching private key.

Email certificates offer robust benefits and features for both personal and corporate clients. Best of all, SSL for email is affordable for any budget. Here’s what an encrypted email brings:

Email Signing Certificates Prevent Phishing and MITM attacks

An email signing certificate is the best remedy against phishing and man-in-the-middle attacks. By encrypting plaintext data and authenticating the sender, a S/MIME certificate eliminates the two most common and dangerous threats affecting thousands of email accounts daily. Secure email is a must for businesses of all niches, and email security should be everyone’s priority in today’s digital world.

Full-scale browser and server compatibility

An SSL certificate for email, as some users call it, is fully compatible with most browsers and email clients, including Microsoft Outlook, Mozilla Thunderbird, The Bat 1+, and many more. You can install secure email certificates on any system of your choice and have peace of mind that your recipients open email communication in any browser, including legacy versions.

Email SSL Certificates enable two-factor authentication

A digitally signed email comes with two-factor authentication out of the box, further improving security. You can enable it on all your employees’ accounts, and ensure the protection of all your sensitive data. Secure email runs as a second authentication element and stops attackers from getting remote access to your usernames and passwords.

S/MIME certificates are FDA ESG compliant

If you’re doing business with the FDA (Food and Drug Administration), encrypting your emails is a must. The FDA has a dedicated platform called ESG (Electronic Submission Gateways), which processes all incoming emails and documents. The ESG verifies the senders’ identity before dispatching the information to the relevant FDA office. Secure Email SSL certificates ensure that your communication with the FDA is smooth and safe.

Email certificates are affordable
