This server is operated by Artikel10 e.V. as part of the Tor network, which is dedicated to keeping Internet users safe.
While Tor is not designed for malicious computer users, it is true that they can use the network for malicious ends. In reality however, the actual amount of abuse is quite low.
If abusive traffic is being sent through this Tor Exit node, we can block access to affected IP addresses that you own from our Tor relay. Please contact us with the necessary information, if you would like us to do so.
The best ways to improve your security posture are completely unrelated to Tor. For example, keeping your systems patched and implementing multi-factor authentication will do more to prevent intrusions than blocking Tor users ever could.
If you still feel that traffic from Tor users is a higher risk than the rest of the Internet, a nearly real-time source for Tor Exit IP addresses is available here:
But please note that blocking Tor Exit nodes might put your own users at risk, when they are using Tor for private and secure communication.
