"The recent incident of "backdoors" in Microsoft software is indicative of a fundamental problem that electronic commerce will need to address very soon," Jerry Harold, president & co-founder of NetSec [...] Even if Microsoft has stringent internal requirements for software assurance, it's very difficult to catch a backdoor that may be hidden by a single coder deep inside hundreds of thousands of lines of code," said Harold

"This is why NetSec builds its products on an operating system (OpenBSD) that has made security its number one goal," Harold told SOURCES. "The source for the operating system was re-built from the ground up for security and is publicly available. As a result, it is continuously subjected to rigorous security review by independent software engineers around the world. This has additional benefits because secure code often tends to be well designed, stable, and efficient."

(netsec being the company that worked with the fbi and employed the developer that wrote the openbsd ipsec code in question)
