Barry, thanks very much for your comments !

Certainly Cisco is bringing decades long experience in Enterprise Security and combining it with OT specific needs. For example Cisco's Identity Services Engine can reach deep into the network to deliver superior visibility into who and what is accessing resources. Through the sharing of vital contextual data with technology partner integrations and the implementation of Cisco TrustSec® policy for software-defined segmentation, Cisco ISE transforms the network from simply a conduit for data into a security enforcer that accelerates the time to detection and time to resolution of network threats.

Also Cisco ISA3K with Firepower delivers an integrated threat defense across the entire attack continuum — before, during, and after an attack.
It combines the proven security capabilities of the Cisco ASA Firewall with industry-leading Sourcefire® threat and advanced malware protection features in a single device. It has inbuilt SCADA Signature that can detect and prevent attack on the electrical grid.
