It's good and I recommend to anyone just running windows firewall. Fourthly, allows you to set profiles on the fly with a click in the system tray and finally allows you to review all connection attempts, inbound and outbound. Thirdly, it adds little things like context menu items where you can just click on a file and allow or block as opposed to having to open up windows firewall and adding manual entries. Secondly that it will not allow a connection to home base to try and download additional components or send your information to God knows who. Secondly, if you have inadvertently installed a piece of malware on your computer, it may do damage locally, but firstly you'll be aware of it maybe a bit sooner because you'll get notifications that something is trying to connect outbound and it will be blocked. Biggest need number one is to control the biggest piece of spyware on your computer. I use it constantly so there is definitely 'a need'. Windows firewall is very good as far as protection, just lacks certain basics. This software just adds that extra control over the existing windows firewall instead of having to install an entirely new firewall software.

as far as 'the need' it's to allow you to control outbound connections in the firewall and be notified, which normal windows firewall lacks badly. Nicely designed, non-invasive and the developer is very responsive to questions. Couldn't ask for a better piece of software. I've been using since before it became part of Malwarebytes and it's awesome.
