This tool simplifies keeping up-to-date with vulnerabilities in the National Vulnerability Database (NVD, formerly ICAT)
. Note that Secunia terminated our feed on October 28, 2014 after a change of ownership, so we are not able to keep you up-to-date on Secunia advisories anymore. Instead of manually repeating your searches, Cassandra does the work for you. It works by saving lists of products, vendors and keywords into "profiles". Whenever new information is available, Cassandra can notify you by email. You can create as many profiles as you want, for networks, typical installs, important hosts, or simply areas of interest to you. The important thing is that you should get emails only for things that are relevant to you, so you don't have to scan every message on various mailing lists.
Please see my blog entry
on new features in Cassandra, and some notes on the limitations of the service.
