07 Remediation

Palo Alto Networks is currently working to improve our inspection engines by adding a URL filtering policy check on both the TLS SNI field and the HTTP Host and URL headers for decrypted HTTPS transactions. Apply any of the workarounds to completely mitigate the risk of evasion. There are currently no PAN-OS updates available for this issue.
