A few great things about NPM - NetPath, Network Insight for Cisco, F5, Palo Alto, Dynamic Maps, Layer 2 and Layer 3 topology discovery.. NetPath is a great hop by hop analysis tool and very useful for troubleshooting network delays, configuration issues, packet drops along the path taken to reach a particular service being served at a TCP port level. Network InSights for various devices are adding more value - eg. Cisco ASA HA topology, Cisco stackable switches, Site-to-Site VPN's, F5 load balancing. Dynamic Maps 2.0 are much better than the erstwhile Network Atlas.

It allows you to track any devices that connect to your network so you have visibility of the assets in your network. It can even block suspicious users by checking the connection information

This allows IT to connect with users to assist with programs. It gives the user the ability to work directly in another OS, which compared to others, is just as good.
