I D C O P I N I O N Network access control (NAC) is seen by many IT professionals today as the most mo promising network security innovation enabling IT to enhance overall network security c.cd and health. i.www IT professionals who have the resources to pilot, beta, and roll out NAC solutions for 5 their enterprises, are gaining valuable early experience and insight to assist them in 104. addressing many of their network security needs. 539.80 Early NAC evaluation trials and experiences are providing enterprise IT with practical 5.F insight into critical business factors, including their return on investment and total cost 0 of ownership, while assessing the overall effectiveness of NAC's ability to provide 028 enhanced network health and security. .278.8 For many companies, however, NAC remains out of reach for practical, financial, 05.P business, and technical reasons. At the present time, main adoption barriers for NAC A continue to exist, including the following: SU 10 ! Lack of a clear and consistent definition for NAC 710 A ! Need for potential large capital and staff investments M ,mah ! Lack of a NAC standard among the vendors gnimar ! Limited vendor interoperability in available solutions F teert ! Mixed reviews of early NAC deployment results S neep Although NAC vendors are slowly addressing several of these adoption issues, such S 5 obstacles continue to be the root cause of a slow adoption rate across the enterprise :sr spectrum. As these adoption barriers are addressed and as more businesses across etra the industry spectrum establish clear and demonstrable successes, IDC anticipates uqd the adoption of NAC to broaden across the spectrum of enterprise sizes. aeH la We are already beginning to see reports of major successes in NAC rollout projects. bolG With adoption barriers addressed and/or minimized and with NAC providing a broader scope of integrated security features, IDC forecasts that the NAC market will continue to grow from its current size of $802 million to $3.8 billion by 2011.
Filing Information: December 2007, IDC #209613, Volume: 1 Enterprise Network Admission Control Survey 2007: Special Study S u m m a r y R e s u l t s
When the results of this survey are examined, we see that nearly 75% of IT professionals representing very large enterprises have already deployed NAC, are in the evaluation process, or are planning to deploy NAC within the next 24 months.
Nearly 60% of large companies reported the same NAC rollout plans as very large organizations.
At the same time, however, this survey report quantitatively shows that as many as 53% of IT professionals in small and midsize businesses participating in this survey have no immediate plans to deploy NAC.
