How does a cloud security solution achieve visibility into TLS/SSL-protected Web traffic?

 TLS/SSL Inspection:

Cloud security solutions achieve visibility into TLS/SSL-protected web traffic through a process known as TLS/SSL interception or inspection.

 How It Works:

The security solution acts as an intermediary (man-in-the-middle) during the TLS handshake.

When a user initiates a connection to a TLS/SSL-protected website, the security solution intercepts this connection.

It completes the TLS handshake with the user's device using its own certificate, and simultaneously performs the handshake with the destination website.

 Certificate Replacement:

The security solution decrypts the traffic, inspects it, and then re-encrypts it before forwarding it to the destination website.

The user’s browser trusts the security solution’s certificate, which replaces the original website's certificate.

 Security Implications:

This method allows the security solution to inspect encrypted traffic for threats or policy violations while maintaining secure communication.
