I have blocked some Applications (like youtube, facebook etc in PAN-OS9.0.0), But employees are still able to access these applications while using VPN (Like ibvpn, purevpn).

If anyone have solution please let me know, how to block that traffic,

Hi @shafi.md ,

Have you tried blocking the proxy-avoidance category ? Both of the vpn tools that you mention fall under that URL category.

If that doesn't work for you then you might want to consider blocking ipsec based on users. For example creating a security policy based on user instead so you can allow certain users to have vpn tunnels while denying everyone else.

Using an application filter you can control all vpn/encrypted tunnel applications which will automatically contain all applications that create encrypted tunnels, and use that in a security policy to control access to these applications :

Hello,

Agreed on the URL blocking and application blocking. Worst case you can block the port that those applications use.
