Most likely, there has been security events relating to your IP address which has caused you to hit a bad reputation. Please review your network and confirm that you have no infected devices. Once that has been confirmed, the IP reputation will naturally improve.
If for any reason the IP reputation score increases again, the likelihood is that you still have something which is infected on your infrastructure.
Often this is caused by:
- Computer/IoT device infected with malware or some kind of virus.
- Scripts or bots (e.g., scrapers) carrying out automated tasks across sites.
This Community Tip has other suggestions to review. Our IP reputation is sourced from multiple places including Project Honey Pot.
