Well, I guess technically MARS doesn't need anybody anymore, since Cisco is in the slow process of killing it.
Cisco Security Monitoring, Analysis and Response System (MARS) is a SIEM product, and by many accounts, well-liked. As early as 2008, however, rumors of trouble in Cisco-MARS-land began to surface. The actual announcement about End of Sale / End of Life (EOS/EOL) came from Cisco on December 3,2010. Now, the last date of support is not until June 30, 2016, but most people who were using MARS are actively looking for a replacement.
