Little Snitch is an application firewall and network monitor from the Austrian company Objective Development. It exposes application network connections and lets a user allow or block traffic through rules and lists.
The tool improves endpoint visibility and control. It reports destinations, not payloads, and a compromised endpoint stays compromised behind it. Rules also require maintenance because blocking an unfamiliar dependency can break legitimate functions.
Swedish and EU privacy suppliers treats Little Snitch as a possible European digital lead. Any resale arrangement needs direct permission, territory, refund, and support terms.
