OCSP stapling is a protocol that an internet server employs to determine the revocation status of a security certificate.

Moreover, it improves the efficiency and privacy of the online certificate status protocol (OCSP) by facilitating the server’s transmission of certificate status data to the client, regardless of the TLS handshake.

This eliminates the need for the client to independently request this information from the certificate authority (CA).
