From the article:
"There is no replacement available for the Cisco Security Agent at this time.
Cisco's network security product portfolio has complementary security technologies, such as Cisco Intrusion Prevention Systems,Cisco ASA 5500 Series Adaptive Security Appliances, and Cisco IronPort Email and Web gateways. Please contact your Cisco account team for more information on these products. While there is no direct Cisco Security Agent replacement product from Cisco, many endpoint security products are available from a wide variety of third-party vendors. We expect that customers will want to do their own due diligence in choosing a replacement product that best meets their needs".
