Zyxel atp 500 very high CPU level

Pietro

I have a Zyxel ATP-500 at my company. For about a month now, the CPU usage has been stuck at a high 90-99% as traffic increases. This prevents anyone connected to the VPN from working, and the internal LAN has been performing poorly. Where can I start checking to see what's causing the CPU usage to increase? Last Firmware. I have active:

Web Filtering, AppPatrol,SecuReporter,Sandboxing,Reputation Filter,Collaborative Detection & Response,Application Security,Intrusion Prevention.

Thanks for your help

Hi @Pietro

Could you help to provide us the HTTPS web GUI access to your firewall to investigate this issue?

I will also send you a private message, so you can share the IP and account (for investigation use) with us.
