Network Access Control
Nothing goes unnoticed

NAC - Network Access Control

Network access control (NAC) systems provide special methods for detecting deficiencies in network configuration and end devices.

They are not necessarily at the top of the list when selecting new IT infrastructure - for this reason, they are especially mandatory for CRITIS institutions, quasi as a back-band control of a possibly too fast and only performance-oriented planning of infrastructure.

SerNet opts for the completely license-free PacketFence. We provide you with in-depth advice and integrate the open source NAC into your infrastructure!


SerNet recommends PacketFence as a trusted, free and open source solution for network access control (NAC). Its impressive feature set can be used to effectively secure small to very large, heterogeneous networks.

  • centralized, wired or wireless management,
  • 802.1X support,

  • integration with the Network Intrusion Detection System (NIDS) Snort and the Nessus vulnerability scanner.
