The network access control (NAC) market has evolved rapidly in recent years and is seen as the core, integrating element of corporate IT security if deployed in the right circumstances, as explained by John Carney in a recent blog post, "Not just NAC".
The explosion of Bring-Your-Own-Device (BYOD) policy requirements with the advent of smartphones formed a substantial part of the NAC evolution, but it goes much further than this with John Carney describing NAC policy servers as being "warehouses of context" in which fine-grained policy enforcement is a key outcome of integration with other security tools that analyse and disposition connected endpoints.
With the imminent Internet of Things (IoT) explosion, smart and automatic decision making at the stage when a device is trying to connect is a vital requirement to maintaining secure networks.
To achieve this, endpoint visibility and platform based integration are necessary factors which can't be compromised if security problems are to be avoided. This is the way NAC is going - beyond Network Access Control.
