NETASQ provides security appliances (Firewall-VPN-IPS) since 1998, which are based on FreeBSD. After a brief presentation of what thos devices provides to customers, we'll see how it has been possible to provide those products using OpenSource components for some parts, specific developpements for others, how some features evolved from one to the other. We'll also see how the R&D team works with the OpenSource community, from minor patches/bugs reports to becoming one of the maintainers of an OpenSource project used in the appliances (ipsec-tools).
Yvan VANHULLEBUS works as an R&D security engineer for NETASQ since 2000, where he works on FreeBSD OS. He started to work on KAME's IPSec stack in 2001, provided many patches for various parts of the stack, then became one of the maintainers of ipsec-tools project, a fork of KAME's userland daemon. He became a NetBSD developper when ipsec-tools was migrated to NetBSD's CVS.
