I don't know of a service specifically designed for hosting companies to detect Content Violations. However, regular manual audits of server activities by your team can help in detecting any unauthorized distribution of copyrighted content.
cPFence Owl does an excellent job of detecting resource-intensive processes and promptly notifying the admin. Additionally, you have the option to add suspected users to the blacklist, and the Owl module will automatically halt these processes for you. Moreover, the Owl module provides round-the-clock monitoring of your server for any CPU, RAM, IO, or disk space issues. You can tailor these features to your requirements by adjusting the configuration file.
Additionally, the IPDB and DDoS protection module provide a solid layer of protection for blocking port scans and probing activity.
You can monitor the blocked attacks by cPFence IPDB by running the following command:
sudo tail -f /var/log/syslog | grep -E 'cPFence Blocked:|cPFence DDoS Protection:'
cPFence typically blocks 5 to 10 IPs per minute for engaging in port scanning or DDoS attacks on average. By following recommended security practices and securing your WordPress installations on the server using our new WordPress Security Tools, you can significantly enhance your security posture without the need for additional services.
