Zero Trust has moved from a strategic framework to an operational necessity.

Forescout’s Vedere Labs research shows that exploits are increasingly moving from the network perimeter into internal infrastructure; with attackers leveraging vulnerabilities in Citrix, Cisco, and other widely deployed network devices to establish footholds and move laterally before detection.

The blog makes the case that perimeter security is no longer sufficient and that the window between initial network access and lateral compromise is shrinking. For organisations with legacy NAC on-premise and ZTNA only at the remote edge, it surfaces the enforcement gap that most Zero Trust programmes leave open and why closing it has become a matter of urgency rather than a long-term roadmap item.

Read the research to understand how the threat landscape has shifted and what it means for organisations still relying on perimeter-based enforcement models.
