Network Access Control
| Segmenting networks by software allows for better enforcement of security policy. Endpoints should be classified by their identities rather than just their IP addresses. You can restrict access by assigning different roles, locations, and permissions for each device, which helps contain suspicious devices and give the right level of access to the correct people. |

| Industrial network security is an extension of network segmentation, which provides additional visibility into industrial control networks. |
