From 2000 to 2003, computer worms such as Code Red, Sasser, Blaster, Sobig, SQL Slammer and ILOVEYOU wreaked havoc on enterprise computer systems. Worms are computer viruses with the ability to rapidly propagate across networked computers without human interaction.

Enterprises were challenged to protect their networks from malware because a single infected computer could act as an entry point for a rapidly spreading worm. The concept of network access control was announced by Cisco in 2004 as a means to stop such threats. Currently, NAC products secure networks by ensuring that all endpoints are compliant with predetermined policies prior to granting access. NAC customers can set requirements for endpoint security posture and control access to resources based on user identity and role.

NAC is able to solve glaring security challenges. Without NAC, enterprises lack visibility into the network and attached systems. Unauthorized users can access the network and certain systems by simply connecting to an Ethernet port or to a wireless access point (WAP). NAC offers many other benefits for businesses. Therefore, NAC initially represented a potentially lucrative and rapidly-growing market.
