Blocking whatsapp web fortigate

[CyberInfra2024]

Hi everyone,

We want to block all connections to WhatsApp web in Fortigate. We tried to block them by blacklist, but the problem is that when we create the FQDN with the WhatsApp web url, and we apply it to the black list, it's not working.

Our temporary solution was to block the public IP of the WhatsApp web url, but it changes quite fast.

Any ideas?

Thanks in Advice

You can use Internet Service Database on Firewall Policy with Action Deny.

You may also block using Application Control
