SG210 with Firmware: 9.411-3 most of the time at 90%+ CPU usage

Hello,
Since yesterday our Firewall is at 90%+ CPU usage. We already stopped the Services which generate the most but the Firewall is still at 90%+. Usually it was around 50-70% and worked without Problems. We didnt install anything new but the Problem suddenly appeared. Does annyone have any Idea why this Problem could still be there and knows of a way to fix it ?

  • According to I understand sg210 it supports 50 users because so few if in the part of specifications are quite high

    As I base to size then because I find very low the number of users supported

  • Web protection and IPS (part of network protection) are the most resource consuming processes on the UTM. WAF, depending on your profiles, number of requests served and hosts protected can also severely impact sizing. That's why although SG210 has a massive throughput, when using those features the number of users supported are greatly reduced.

    If you were using only firewall, sure, SG210 would suffice. But, for your scenario, you should consider an SG310 for some room to grow or, at the very least, an SG230.

  • I have to side with Giovani's view on this.  If this is still the first 30 days, get Sophos to take it back and sell a 230 at least.

    An experienced UTM installer might be able to help if you're stuck with that device.
