Mac application firewall to monitor and control connections



Outbound is an outbound application firewall designed for macOS that monitors which applications communicate over the internet. Updaters, telemetry services, crash reporters, and analytics trackers frequently transmit data in the background without user intervention. Outbound reveals these connection attempts, showing the originating program, remote destinations, transfer volumes, and the reason traffic was permitted or blocked.
When software attempts to reach a new address, Outbound prompts the user to either approve or deny the request. Rather than displaying vague connection strings, the app identifies developer certificates, flags whether destination servers belong to the application maker, and can quote stated developer policies. Users can apply actions permanently or across several temporary durations.
Unlike tools that send activity logs to remote infrastructure, Outbound keeps all network monitoring data, history, and filtering rules directly on the local machine. It uses an offline geographic database to map connection routes across 2D maps and 3D globes without transmitting search queries off the Mac.
Outbound is built for Mac users who require strict visibility and authority over background network activity, including:
A user discovers background analytics or telemetry pinging third-party servers while running teleconferencing software. Outbound detects the remote hostname and lets the user deny telemetry specifically while keeping primary call functionality fully operational.
A developer testing application updates wants to verify that network calls target the intended staging API and do not send unnecessary data. Using the Network Monitor, the developer filters by application name to measure transmitted bytes and confirm the exact port and protocol in real time.
A remote worker frequently switches between public and private networks. Outbound applies localized profiles, preventing unapproved utilities from broadcasting data over insecure Wi-Fi without explicit user authorization.
Outbound uses a paid licensing model with no recurring subscription fees. A founding offer provides licenses for $29 for the first 50 purchases, followed by a regular one-time purchase price of $39. Each license permits activation on up to two Macs. There is no account sign-up required to use the software.
Outbound serves as an alternative to Little Snitch and LuLu. While those tools also manage outbound macOS traffic, Outbound differentiates itself with a native 3D globe and 2D geographic monitor powered by an offline database, built-in process folding for multi-process apps, and a flat one-time pricing model without recurring fees.
What are the system requirements for Outbound?
Outbound requires macOS 14 or later and runs natively on both Apple silicon and Intel Mac hardware.
Does Outbound require an account or subscription?
No account creation is needed, and the software is sold as a one-time purchase without recurring subscription charges.
