Generating much excitement back in 2018 was bpfilter for the potential to better Linux's firewall and packet filtering by making it more robust and performance. Recently work on this BPF-based firewall solution was renewed and the performance potential over iptables and nftables is looking very good for the future with more feature work planned around new matches and targets, containers integration, in-place upgrades support, privilege separation, and BPF code optimization support.

It's no doubt that one of the leaders for network equipment is Cisco Systems. Newer Cisco devices are starting to use what Cisco calls its "IOS-XE" operating system, which is a customized flavor of GNU/Linux. Yes, GNU/Linux, which should not come as any surprise as GNU/Linux is used on countless high level appliances and security devices.

Fwbuilder is a unique graphical firewall tool that allows the user to create objects and then drag and drop those objects into firewalls, to build a powerful security system for a single PC or a network of PCs. Fwbuilder supports a wide range of firewalls (Cisco ASA/PIX, Linux iptables, FreeBSD's ipfilter, OpenBSD's pf, and more), so its rules can be deployed on multiple platforms.

Traditional firewalls might not be enough, argues Palo Alto Networks founder Nir Zuk. The world is very different from the days when email ruled the roost and Yahoo, not Google, was the first search engine name that rolled off your tongue.
