Why bulk order email signing certificates?

Email signing is the most effective way to prove your emails are authentic, secure, and tamper-proof. Email signing only gives you full protection if both the sender and recipient have a certificate installed. Every single employee who sends signed emails needs their own certificate. That can snowball fast for large companies—unless you make a bulk order.

Why email signing certificates?

Email spoofing is easier than you think. Email signing lets recipients instantly verify who really sent the message. It’s cryptographic proof. A digital signature is applied to your message. That signature is hashed along with the content of the email. When the recipient opens it, their email clients check the hash and the sender’s certificate.

What is document signing?

Using document signing with your Personal Authentication Certificate (CPAC)

You can use Comodo Personal Authentication Certificates (CPAC) to sign documents, too. One certificate, double the performance. A digital signature is applied, and the data is hashed. Whoever opens your document can instantly verify that you sent it, and it hasn’t been tampered with.
