Detect Tor exit nodes online for free

The Tor network is made up of volunteer-operated computers that enable users to browse the web anonymously. When data leaves the Tor network to access websites, the website only sees the exit node IP address (as opposed to the original user’s), which helps protect privacy. However, malicious actors can still monitor Tor exit nodes and deanonymize users.

Detect Tor exit nodes online nodes is one way that organisations can better defend against these threats. To help with this, WatchGuard offers a free online tool that lets you check whether an IP address is listed as a Tor exit node. This service enables you to verify up to 50 IP addresses at once, and leverages public lists that are frequently updated by the Tor Project.
