Multiple destinations
Rules can cover a list of multiple hostnames, domains or arbitrary IP address ranges, helping you to simplify your ruleset.
A firewall protects your computer against unwanted guests from
the Internet.
But who protects your private data from being sent out?
Little Snitch protects your privacy!
As soon as you’re connected to the Internet, applications can potentially send whatever information they want to wherever they want. Sometimes they do this for good reason, on your explicit request. But often they don’t.
Little Snitch intercepts these unwanted connection attempts,
and lets you decide how to proceed.
Network Monitoring Redefined.
Take a look under the hood to see at a glance who talks to whom. The Little Snitch Network Monitor raises the bar of network traffic monitoring to an entirely new level. The realtime diagram provides fine grained traffic information, combined with powerful yet simple options for analyzing bandwidth, traffic totals, connectivity status and much more.
- Detailed traffic history of the last hour, separate for each process, server, port and protocol.
- Display of total traffic amounts, peak traffic, average bandwidth, etc.
- Variable zoom from one hour down to one minute time range.
- Filtering by process name, server, port, etc.
- Versatile grouping and sorting options.
- “Show Corresponding Rule” quickly shows why a particular connection was allowed or denied.
- Display of system events (app launch or termination, sleep) to see network activity in its context.
- Indication of connections denied by Little Snitch.
- Capture network traffic in PCAP format.
- Save Snapshots for later analysis.
Take back control of your system.
Whenever an application attempts to connect to a server on the Internet, Little Snitch shows a connection alert, allowing you to decide whether to allow or deny the connection. Your decision gets stored as a rule which will automatically be applied to future, similar connection attempts from the same application.
Silent Mode – Decide Later
There are times where you don’t want to get interrupted by any network related notifications. With Silent Mode you can quickly choose to silence all connection warnings for a while. You can then later review the Silent Mode Log to define permanent rules for connection attempts that occurred during that time.
Research Assistant
Have you ever wondered why a process you’ve never heard of before suddenly wants to connect to some server on the Internet? The Research Assistant helps you to find the answer. It only takes one click on the research button to anonymously request additional information for the current connection from the Research Assistant Database.
Automatic Profile Switching
Rules can be arranged in different profiles like “Home”, “Office” or “Mobile Internet”. This allows you to use different sets of filter rules depending on the network you are currently connected to.
Profiles can be activated either manually from the status menu, or automatically, whenever you join a network that’s associated with one of your profiles.
Firewall for incoming connections
Little Snitch not only reveals any outgoing network connection attempt to make sure that sensitive data doesn’t leave your computer without your consent. The inbound firewall in Little Snitch provides you with the same level of control for incoming connections.
And so much more…
Temporary rule options
Various rule lifetime options allow you to create rules that are effective only for a limited time.
System Process Rules
Rules are created for a specific process owner, making it easier to define rules for system level processes such as web servers.
Rule Suggestions
Rule suggestions are based on your previous network usage profile and can be turned into permanent rules with just a single click.
Ask Rules
This rule type enforces connection alerts for particular connections, even if some other, more general rule would already allow or deny these connections.
Ruleset Analyzer
Little Snitch automatically analyzes your ruleset and shows any redundant, overlapping or invalid rules, helping you to keep your ruleset simple and clean.
Domain based rules
Rules that are effective for an entire domain can be created right from within the Connection Alert.
Improved status menu
Quickly switch between profiles, turn on Silent Mode, access your rules, and see a summary of current network activity.
