Sectigo Email Signing certificate

Summary

Assert Sender Integrity

When you sign your emails, your signature undergoes a hashing process, and the resulting hash value is incorporated into the email signing certificate. The recipient's email client then performs that same hash function to verify the matching values and authenticate the signature, thus protecting employees against spoofed emails. The recipient's email client then performs that same hash function to ensure the values match and the signature is authentic, thus preventing spoof emails from getting past your employees.

Ensure Message Integrity

After your email is signed, it's hashed along with the signature and sent along to the recipient. Because even the tiniest alteration to the data being sent will result in a different hash value when the recipient's client repeats the hash function, it acts as an instant indicator if anything is amiss.

Stop Spoofing

Each year business email compromises account for greater and greater losses. The only way to prevent this kind of spear phishing attack is to ensure that every person in your company has an email certificate, signs every email they send, and treats unsigned emails as untrusted ones.
