Last update April 10, 2013

I have put no ads on this page and I am not affiliated with any of these tools.

Over the years, I've looked across the internet for interesting and useful networking tools and I've noticed that searching by search engine generally gives up the same "old" results. Like things from 4 or 5 years ago that aren't useful or updated any more.  (How many times do you see the sectools list of best security software *from 2003*?)

I decided to make this list to help out. Some of these programs are not new, some are not free (most are) and some are even included in Windows or Linux. Most have descriptions, some do not, I hope to add descriptions to all of them, but it takes time that I do not have.

Shoot me an email at boardstretcher (gmail) if you have anything you think should be added.
