Managed Security Services is stable. Or I should say it is stable provided that you look after the system properly. One thing that we have seen is that you need to fine-tune the system so that you do not get unwanted alarms.  

For example, if a firewall is giving out 100,000 alerts an hour, it is difficult for us to manage it efficiently at that rate of alerts. And then it will be difficult to log the visitors also. The trick there is to make sure that you have got the correct rules applied to the system to repress the unwanted alerts coming into the system. If that is done properly, then it is easy to manage and it is very stable.
