Based on the TLS handshake shown, what can be inferred about the client?

In modern TLS handshakes (starting with TLS 1.3), the Client Hello packet includes a specific extension called supported_versions. This extension lists all the TLS versions the client is capable of using. Typically, a client supporting TLS 1.3 will also list TLS 1.2 for backward compatibility to ensure it can successfully negotiate a secure connection with servers that have not yet upgraded. When both versions are present in the supported_versions field, it signifies that the client is capable of both TLS 1.2 and TLS 1.3 . This is a critical component for FortiGate when performing deep SSL/TLS inspection, as the firewall must understand the negotiated version to decrypt the traffic for security analysis.
