Network Segmentation is a cybersecurity strategy that divides a network into smaller, isolated segments to limit traffic flow and reduce security risks. By separating systems based on function, trust level, or sensitivity, segmentation minimizes the attack surface and prevents unauthorized lateral movement within IP infrastructures. It is particularly critical in IP-based broadcast and media environments, where control systems, media flows, and management interfaces must remain protected and resilient.
What Nevion Does
Nevion integrates network segmentation principles into its software-defined media networks. Through solutions such as VideoIPath, broadcasters can logically separate media transport, orchestration layers, and management domains. This structured approach enhances security in SMPTE ST 2110 and distributed production environments while maintaining operational flexibility and performance.
Additionally, Nevion Virtuoso supports deployment in a network-segmented architecture. The Virtuoso IPME media function specifically provides segmentation-related controls such as network isolation, VLAN support, and WAN/LAN separation, further strengthening the security and resilience of IP-based media networks.
Beyond network-level controls, VideoIPath extends the principle of segmentation to the orchestration layer through two key capabilities: multi-tenanting, which provides restricted, role-based access for specific departments or external organisations so that each tenant only sees the resources it has been granted, and federation, which allows autonomous VideoIPath instances, at different sites or within different areas of a facility, such as ingest, production, and playout, to collaborate while keeping each site’s resources isolated and under its own control. Together, these capabilities reinforce segmentation across distributed and multi-organisation production environments.
Benefits & Advantages of Network Segmentation

Common Questions
Q: Is segmentation only physical?
A: No, it can be logical or virtual.
Q: Does it affect performance?
A: When properly designed, performance remains unaffected.
Q: Is it necessary for broadcast networks?
A: Yes, especially in IP and cloud-enabled systems.
