The EOL/EOS notice has me wondering about Cisco’s commitment to Network Modules and also the viability of NAC. EOL/EOS for the Cisco NAC Network Module [Cisco NAC Appliance (Clean Access)] – Cisco Systems: “”
Makes me wonder if Cisco’s commitment to Network Modules is a thing of the past. I would think that the cost of appliances is cheaper and easier to build (because of merchant silicon/commodity hardware whereas the ongoing development of the modules would be relatively difficult.
May also suggest that Cisco’s ability to manufacture products cheaply and quickly is worse than I previously thought. The value of Network Modules is that they drives sales of bigger and more expensive routers by making them useful for more than just routin. If the Security BU is turning away from their own manufacturing so they can progress products faster, then that will impact the sales of core products. In which case acting individually is damaging to whole company.
Alternatively, and much more likely, is that NAC is not selling well and this is a signal that Cisco needs to reduce costs in the NAC division to wring some profits out of the product line. I haven’t heard much about NAC since it’s brief burst of glory a couple of years. The only discussion I’ve seen is how difficult and expensive it is to use and maintain. That’s isn’t Cisco’s problem, but the challenges of putting a security layer over Microsoft Windows. That would be enormously difficult and probably impossible.
Overall, good for customers. While NM’s have their place, I’ve never bought any and never plan to. NAC continues to be a niche product, and with Cisco moving to embed security into the network equipment (if that is what I understand SecureX strategy to be) then NAC is less core to the business overall.
