Much of my older blog entries are still here, but I have moved to a Blogger-based blog. Over time all entries on this site will be moved there.

The TIS FWTK was delivered via FTP to DARPA 15 years ago today. The next day we delivered it to DUNSnet. We did change the firewall industry with its delivery. And then we changed firewall pricing as Steve Walker and I, doing a "back of the envelope" SWAG decided on $15K for software only, $18K with hardware. Other vendors, with pricing at over $50K dropped their prices within a week.

Best wishes to its daddy, Marcus Ranum.

It's still the most fun I had in a job, my own consulting gig a close second. Read something historic at Firewall TookKit.

As early as v1.0, the firewall toolkit had "application intelligence," also known as "application awareness," and "deep packet inspection." We just weren't marketing guys.
