Firewall Scudo 3.0.4 for Mac
Scudo is a hybrid macOS firewall by Murus that combines inbound network-layer filtering with outbound application-layer control in one lightweight interface.
What Scudo does
Scudo helps protect Mac network services (for example sharing-related services) from unwanted remote access while also controlling which local apps are allowed to connect to the internet. When configured in interactive mode, it can prompt you to allow or deny connections on the fly; in quieter modes, policies run with less user interaction.
Rules can be broad or granular: allow/deny by app, IP, IP range, hostname, domain, and service definitions. The app also supports global block lists (IP/CIDR), temporary or persistent rules, and profile switching for different environments (home, office, public Wi-Fi).
Security workflow highlights
Scudo includes location-aware behavior for untrusted hotspots, so inbound access can be blocked automatically on less trusted Wi-Fi networks. It also provides per-app policy management and a setup assistant to help non-expert users get started quickly.
Version 3.0.4
The Mac App Store entry for version 3.0.4 (dated 18 Oct 2023) lists one explicit update note: added compatibility with macOS Sonoma. Public vendor pages describe Scudo 3 feature set in general, but do not publish a detailed itemized changelog specifically for every 3.0.x patch on-page.
Requirements and licensing
Scudo 3.0.4 requires macOS 11.3 or later and runs natively on both Intel and Apple Silicon Macs. The app is available in Web and Mac App Store editions with small licensing/update differences documented by the vendor; App Store edition supports Apple Family Sharing and automatic updates through the App Store.
