“LogicMonitor has the ability to gather information from a variety of enterprise systems as well as specific services on them. It provides aggregated event data from separate network and security devices, as well as application servers into comprehensive and usable information.
It has the capability to analyze and correlate information from multiple sources including firewalls, vulnerability scanners, intrusion devices, servers, and others, to help identify attack patterns and provide immediate alerts.”
