Scudo overview

Scudo is a hybrid firewall for macOS that combines an inbound network-layer packet filter with an outbound application-layer firewall. Scudo helps protecting your Mac’s network services from unwanted connections from remote computers and improves your privacy and security controlling all apps network activities, allowing you to choose which app is allowed to connect to the network. Everything is controlled in a single window, its usage is really simple and safe. Scudo uses a new technology to identify processes and apps: signature fingerprint. Because of that you are always sure that only genuine apps are allowed to connect. Should an authorized app be modified, hacked or tampered with, Scudo will notify it an block it. Additionally, a real-time apps connections monitor allows you to check all network activities of your Mac. A detailed PDF manual is included in the package. Scudo is derived from Murus and Vallum, and is a simpler and friendlier alternative to them.

Key features:
  • Easy to install and use
  • Protect your shared documents and network services monitoring open ports
  • Protect your privacy blocking apps connections on the fly with live notification alerts
  • Identify processes and apps by their signature, verify signature and certificates validity and integrity
  • Protect your network from well-known dangerous hosts using on-line blacklists
  • Monitor real-time apps connections and bandwidth usage
  • Per-app bandwidth throttle: give each app its own dedicated bandwidth limits

Scudo is really simple. One click to install, it runs automatically at user login, it stays in a corner in the macOS menu bar, near the clock. It does not need any kind of configuration or maintenance as everything is automated. Scudo can be used as a completely silent firewall or can be setup to require user interaction when a new open port is found or when an app attempts to connect to the network. It's usage is much simpler than Murus or Vallum, all features and controls are grouped in a single window where both inbound and outbound firewall rules are displayed. All changes are applied immediately. Scudo is able to securely identify processes and apps by their signature fingerprint instead of absolute path. Additionally, Scudo allows you to assign each app a maximum download and/or upload bandwidth. Scudo Package includes an uninstaller and a detailed PDF manual

This is an excellent program. Easy to install and use. It can give control similar to Little Snitch, but much easier (using the "Ask" option). I'm hoping it would catch any ransomware trying to phone home before my anti-virus finds it for instance; Scudo seems to be catching everything so far. The asks from using the Ask on Everything profile requires a few hours of usage until most of the asks are done. Once "broken in", name and save your profile. Lots of pre-made profiles to choose from, though. There is a nice little traffic monitoring window you can open to watch your trafic should you choose. If you happen to over-restrict, just open up the configuration window, enter the admin. password to unlock, and click the "pass" option for the restriction. I opted to have little windows open, with a little ding sound, to let me know a new connection is being attempted. Right there, click pass or block, and how long .. easy. Hard to go wrong, especially for $10.

Scudo 1.0.1 Awesome app. Little Snitch and Hands Off! start to look around nervously. Many thanks to the developer for his generosity. An application of this level and for such a ridiculous price is something new. From now on, Scudo is on my list of Mac OS app favorites. I hope the application will not be abandoned and will only improve. Hats off to the developer.

(Beta 8) Installs like a charm, setup wizard clear and concise, as far as I can tell after a few days it does what it says and says what it does. In comparison to others, Scudo is faburama. Full 5 stars.

Wow, this is great and I love it. Easy to install and easy to use. Thank you very much.
Very good control over ingoing and outgoing traffic and a good network monitor and the ability to take snapshots. IPs can be banned via lists. There's a live view of what's being blocked or passed behind the scenes within Scudo. Very nice interface and you can choose either dark or light or same as OS. A lock is shown at the bottom to prevent changes. That's a good idea! If you have Murus like me remember to uninstall the pf-scripts before installing Scudo. There is also good documentation as a PDF so you can get the most out of this.
There's even more to explore. I think it's great and worth 5 stars. I hope this gets further development! ???

So if I understand well, when murus and Vallum are already present this is unnecessary, As per dev infos : "Scudo is a hybrid firewall for macOS that combines an inbound network-layer packet filter with an outbound application-layer firewall." = Murus + Vallum
Is he trying somehow to kill its 2 others creations? whats up?
whats the point?
