Cisco have announced the End of Life for Cisco MARS.
“Cisco announces the end-of-sale and end-of life dates for the Cisco Security Monitoring, Analysis, and Response System. The last day to order the affected product(s) is June 3, 2011.”
The end of an Era, for probably the largest deployed SIEM tool out there.
I think its also important to note, Cisco’ stance on future SIEM type products from the release notes “There is no replacement available for the Cisco Security Monitoring, Analysis, and Response System at this time.”
