How PKI keeps your email secure

DigiCert PKI for email validates the identity of email users, encrypts email information so it can’t be read by anyone who doesn’t have authorization, and provides an extra layer of security for both the sender and the recipient. This is especially important given the steady rise of phishing and spear-phishing attacks. Because both sides of a given communication are identified with a unique private key, messages can’t be altered, intercepted or spoofed in transit.
