What is RBL Monitoring?

We check your IP addresses and domains against the most frequently used blacklists, DNS filters, and threat exchanges.

How it Works​

Enter Your IPs & Domains​

Getting up and running is as simple as giving us a list of IP addresses and domains that you’d like us to keep an eye on, and we’ll get right to work!

  • You can list individual IP addresses (IPv4 and IPv6), domains, IP ranges, CIDR blocks, or use our simple bulk loader.
  • For more advanced configurations, you can manage your hosts and contacts by integrating directly with our REST API.

We Monitoring Hundreds of Data Sources​

We continually monitor the most commonly used RBLs, URIBLs, DNS filters, and Social Media threat exchanges.

  • You have full control over which data sources we monitor, how frequently, as well as when and how we send you alerts, letting you customize your experience.
  • Our system reduces false positives and filters out noise.

We Send Your Alerts When Your Get Listed​

We’ll send you alerts as soon as an issue is found with any of your hosts- so you know about issues before your customers do!

  • Select from over a dozen different ways to receive event notifications, each with customizable contact groups and scheduling settings.
  • Integrate RBL Monitoring into your existing monitoring process by using our REST API, or using our API call-back feature.
