My main use case for Cisco Crosswork Network Insights is networking across L1, L2, L3, and L4 networks.
A specific example of how I use Cisco Crosswork Network Insights for those networks is to manage a switch, and another is sending to the L4 network to share data with the management servers.
I have used Cisco Crosswork Network Insights for cybersecurity in this project for L3 and L4 networks, and we have also used it for cybersecurity purposes.
