How Client Certificates Work

Client Authentication Certificates

Generally, Client Certificates (authentication certificates) are used for two-factor authentication. Once a server is configured for client certificate authentication, it will only grant user access to it if the client presents the correct client certificate. When using a web browser to connect to the server, without the correct client certificate, the client cannot even access the credentials page.

Email Client Certificates

Email client certificates have a public/private key pair. Your private key stays with you and is used to sign outgoing emails and decrypt incoming emails encrypted with your public key. Your public key is used to verify your signature and encrypt emails sent to you.

Client certificates allow you to secure your network, applications, and interfaces, only permitting access from authorized individuals.

S/MIME is a standard technology for email encryption. Use a client certificate to achieve one of the most important parts of enterprise data security.

Digital signatures allow the senders and recipients of email communications to verify that the content they are sharing is legitimate.
