Is a hardware firewall designed for PCIe available?
There are solutions that combine hardware security features with PCIe connectivity, offering enhanced online protection. Devices like Ubiquiti Unifi Security Gateway or Firewalla can be adapted into PCIe cards, providing firewall capabilities similar to wireless security hardware. Such setups allow integration into systems for improved online safety.
Your router should already do all this, you only need to firewall between the Internet and the LAN. Granted if you're connected to public WiFi there may be merit there, but even then the benefits of a separate box vs the software firewall within your OS is questionable. If you're paranoid then a router that can connect to WiFi (not sure any can at stock, but any that support OpenWRT firmware can) could provide that additional isolation, it wouldn't make much sense to do this on a PCIe card as there is simply no market for it.
