We use Sonicwall Products extensively as we think they do the job well for a reasonable price but whilst poking around the interweb I found an interesting report from last June 2010.

It appears that the Giant Canadian Teachers Pension Fund who are I believe one of the largest in the world and most profitable were trying to buy them out lock stock and two smokin....

They pulled out after there bid of $11.50 CDN was turned down but clearly fund managers globally still see the Internet Security Market as a good place to invest...

I'm thinking of setting up a new SIP and focusing just on Internet Security companies, are there any financially astute Edugeekers out there willing to make a few suggestions of companies I should consider adding to my Internet Security Portfolio assuming they are Publicly Listed.
Does anyone already have any such companies in a SIP and how have they performed in the last few years?
