Please note: This is NOT a duplicate of earlier questions of this sort. As of 2017, market landscape has changed; most solutions historically recommended got discontinued or made paid only.
So. After spending the whole yesterday fixing the consequences of a Comodo Firewall update, I decided to look for an alternative. What I need is:
Something able to run on Windows 7 SP1 64-bit.
Free. I'm not paying my bucks for a tool that can break any moment like Comodo did.
Alerts and rules for incoming and outgoing connections. Glasswire won't do; its free version is merely a traffic indicator.
Not just an UI for the built-in Windows firewall.
Supported. This part rules out Outpost, Privatefirewall and many other once great solutions.
Not overly worried about HIPS and such. Can live with a complicated interface. Resource consumption is not an issue - it's an i7 rig. Any suggestions?
