Definitely, Security in nowadays, is a lifetime "must-haves", in our capital expense budget. Security is a big issue for anyone. Individuals, small, medium or large businesses, Research & Design environments (even if we have a air-gap network), Industries with PLCs or PACs based in a SCADA architecture, etc. But, thanks Cisco, through its continuous innovation, in the software or hardware, customers could find an adequate solution,to their particular needs or requirements. My personal slogan, shared with my colleagues and some blog post is: "In Cisco We Trust", as a seal of proof. Thank you for sharing your insights regarding this important theme. Deeply appreciated, with my respects.
