WireCee
A personal firewall for Windows and Linux that shows what every program is talking to, and lets you stop it.
WireCee reads the real connection tables itself, enforces its own rules through the Windows Filtering Platform (nftables on Linux), and can filter DNS for the whole machine. The window and the command line use the same engine, so they never disagree.
What it does
Allow, block or ask
Per application. Ask refuses a new program until you decide, so nothing new gets out unnoticed.
Rules that scale
By address, port, protocol and direction, with lists of hundreds of addresses in one rule.
Known C2 servers blocked
A built-in rule blocks known malware command-and-control servers, from the TweetFeed list.
DNS filtering
Your own blocklist for the whole machine, with a guard so programs cannot go around it.
Data usage
Per day and per application, with a monthly limit and alerts.
Local network devices
See what is on your network and give devices names you recognise.
Tamper alerts
Changes to the hosts file, DNS servers and proxy settings, incoming Remote Desktop and modified executables.
Command line
wirecee connections, block, usage, devices, alerts, dns and more. Query commands need no administrator rights.
