Domain monitoring

Know about a blacklist before your customers do

A block from a security vendor or a spam blacklist rarely announces itself. Visitors see a warning, emails go to spam, and you find out days later. Monitoring checks your domain on a schedule and tells you when something changes.

What domain monitoring covers

Your domain has two reputations: one with security vendors that decide whether browsers, antivirus and firewalls let people visit your website, and one with spam blacklists that decide whether your email reaches the inbox. Good monitoring watches both.

  • Security vendors

    Browser warnings, antivirus blocks and firewall categories from 90+ security vendors, such as Google Safe Browsing and Fortinet FortiGuard.

    Website blacklist removal
  • Spam blacklists

    Domain and URI blacklists that mail servers check, such as Spamhaus DBL and URIBL, across 20 lists.

    Email spam blacklists
  • Regular checks and alerts

    Your domain is checked on a schedule, and you get an alert when a new listing appears, so you can fix the cause and ask for removal quickly.
