Is Cisco Back (as an enterprise security leader)?
It wasn't too long ago that Cisco was a dominant force in information security technology. The company was a market leader in firewalls, IDS/IPS, and email security and was actively pushing products for endpoint security and SIEM as well as security "blades" for Catalyst switches. Heck, Cisco even articulated a bold vision of "self-defending networks" with security policy, enforcement, and intelligence all baked into the network.
Since then, Cisco, like Microsoft has seen hard times in terms of security. But maybe that's changed - check this out http://www.networkworld.com/community/blog/cisco-back-enterprise-security-leader?source=NWWNLE_nlt_security_2014-05-23
