With the online-based monitoring we've set up, we've been able to watch trends of attempted attacks on our network, and we're also able to monitor our account issues internally as attackers attempt to log into our accounts.

The primary thing I use it for is monitoring IPS because we have 12 or 14 Cisco IPS devices, and the Cisco solution for monitoring that many IPS devices is hokey at best, aside from it being expensive.

There are things like dashboards and reports (pre-configured and custom) that let me know that things are operating the way they should be, and when they are not.

As we're an SMB, I would like to see different licensing options and the solution is priced out of the reach of some small businesses.

Issues that could have been resolved in 30-60 minutes sometimes took months, but they have improved.

One of the things that actually opened a ticket about (and they couldn’t help me) is when traffic is leaving our network, it’ll only report the source.

Ease-of-use for end users that do not spend every day in the product. Also, the presentation of historical and trending data in dashboards needs to be improved immensely.

The dashboards need to be improved. It gives you so much detail, but sometimes too much detail, especially to an executive, it's too much.

It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there.
