One of the fastest growing (based on number of new companies, not
revenues) segment of security companies, from a product perspective, are
companies who do not have much intellectual property beyond nice web
management interfaces. To be more specific it is the huge growth in
companies who have built security "appliances", web interfaces on top of
Nessus and Snort. Obviously this fast growing area of "I want to be a
security company to" has died down a bit as investors have started to
realize you need more than pretty reporting on top of someone else's
open source project. There are obvious exceptions though with the lead
developers/creators from both Nessus and Snort starting up their own
companies based off the open source projects they work on.
Some companies that start by ripping off, I mean borrowing, open source
tools eventually do try to branch out and develop their own
signatures/checks/engine moving forward. nCircle is a good example of a
company starting off as a web interface on top of Nessus. This actually
does make for an easier way to kick start your own security company.
Obviously to sit down and truly write your own IDS/IPS and Vulnerability
Scanner is a rather large task to do without any funding. However,
creating some web management off of something that already exists, and
then finding some VC who do not know any better than to hand you say 50
million, does put you in a place where you now have the money to attempt
to build your own real solution. There are all sorts of examples of this
in the Scanner/IDS space.
