Sectigo Email Signing certificate

Assert Sender Identity

When you sign your emails, that signature is hashed and the hash value included in the certificate that is presented along with your email. 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 these kind of spearphishing attacks is to ensure that every person in your company has an email certificate and is signing every email they send. And unsigned email is an untrusted one.
