In a nutshell, we found that adoption took these cutting-edge companies longer than expected, and what they're getting out of NAC is slightly different from what they had planned. Moreover, with upward of 20 companies still calling themselves NAC providers, the market is ripe for consolidation. This year already we've seen three vendors exit the space, but even as they go, a few startups are entering.
What they'll find is a skeptical consumer base: Two years ago, 50% of companies said they were deploying NAC. Now just 22% make that claim. Those hardy souls still evaluating NAC face a spotty track record; a long implementation cycle; and, depending on their requirements for control at the network edge, an eye-popping price tag. Add to that the continued evolution of just what this technology does, and you've got a recipe for disillusionment.
For organizations that can sit tight, delay may not be a bad thing. Relying on edge switches to serve as enforcers leaves NAC vendors to concentrate on policy engines, management interfaces, and reporting systems that meet regulatory compliance needs. And while you've lingered, the love/hate struggle that exists among Cisco, Microsoft, and the Trusted Computing Group--home to more infrastructure vendors--will have worked itself out a bit.
