This is good stuff. The 4 products Adam mentioned perform Network Behavioural Anomaly Detection (NBAD). NBAD is an added layer - complimentary to NIDS/NIPS. This is a very good article for those interested: http://www.networkmagazine.com/shared/article/showArticle.jhtml?articleId=163700677&pgno=1 Despite the marketing pitch, MARS is not an NBAD product and should not be in the NBAD quadrant when Gartner puts it together. Aggregation and correlation tools like Protego (sorry Cisco..) MARS look at a bunch of different information and assess the importance of events - a good NBAD product should profile the behaviour of the network in real time and not wait for devices to start hinting at issues. I have questions about products that depend on flow info from routers etc - if you are being badly DDoSed then I am not sure that these devices will be accurate in providing the necessary intelligence for accurate mitigation. In fact Netflow is widely considered to be inaccurate at times ( I can reference examples of 200% utilisation reporting etc...), a serious issue for UBB etc, and as we all know when the bad stuff happens the availability and integrity of the information is extremely important. Hence why most of the NBAD platforms can gather information from the wire independent of Net/c/sflow via SPAN/tap etc. Also Cisco are investors in Arbor and have incorporated Riverhead. The Riverhead stuff is very good at dealing with anomalous traffic, and they are also pushing MARS as some kind of anomaly detection solution. I have also heard that there is some protocol anomlay detection in Cisco IDS. As a representative of Cisco Gary, perhaps you could let us all know what Cisco's roadmap is for these supposedly competing products they have invested in? I am confused!

That list is handy, but incomplete. Cisco MARS should be added. MARS is a SIM product that receives log information from various sources (firewalls, routers, switches, IDS/IPS, host logs, antivirus, and more). It also receives netflow, and can provide very useful security-related information based on it.
