Today, I have found this exciting research project called Project Turris from Czech Republic’s domain registry CZ.NIC. In a nutshell, it seems to be an opensource firewall which is based on OpenWrt Linux. Hardware design is also open. Security component is called distributed adaptive firewall. Security fixes are also distributed to the nodes from the Turris central. I have already registered to get one box but not sure if I can get one as priority seems to be given to those living in the Czech Republic. I was thinking of testing but apparently contract requires to share some data. I need to read what is really shared though. If anyone manages to get one, I would love to hear feedbacks!
