It is very stable. I've been comparing it with quite a number of other solutions. I also have seen , RSA Live , Cisco Threat Grid among others. RSA has a very interesting platform  called the RSA Live, which also provides threat protection feeds, warning feeds, and API integrations, like what X-Force does.

Basically, X-Force gives me a lot of comfort. I can quickly do my threat hunting activities in a few minutes and am able to find  relevant threat details to help me understand a possible threat and the associated risk.

There is very good stability.

It has a lot of stability.
