Network Access Control (NAC) and segmentation help organizations regulate who and what can access network resources. By segmenting networks, they limit the spread of threats and protect sensitive data within defined boundaries.

Network Access Control (NAC) enforces security policies by verifying devices and users before granting access to the network. Combined with network segmentation dividing the network into isolated zones, it restricts unauthorized access and reduces potential attack surfaces. This layered approach minimizes the impact of breaches by containing threats within specific segments, improving visibility, compliance, and overall network security posture. Effective NAC and segmentation are critical for safeguarding sensitive data, maintaining operational continuity, and enhancing defense-in-depth strategies.
