Nine months after it acquired Funk Software for $122 million, Juniper Networks (Quote, Chart) is rolling out network access control (NAC) security products based on Funk’s technology. OAC is an 802.1x supplicant, which is defined a piece of software that provides access to an 802.1x- enabled network. Oliver Tavakoli, vice president of engineering at Juniper (and the former CTO of Funk Software), explained that 802.1x helps a network figure out at a port-by-port level who is accessing the network and what kind of access to allow.
