<\/div>\n

Whenever people click a link, open an app, or visit a website, the very first thing their device does is ask the Domain Name System (DNS) for directions. Protective DNS turns that humble step into an early-warning radar, stopping malicious traffic before it ever reaches your network. In plain language, Protective DNS checks every domain request against constantly updated threat intelligence. If a request points to ransomware, phishing, or any other malicious destination, the connection is blocked instantly and the user is steered to safety.<\/p>\n

<\/p>\n

How Protective DNS Works in Three Simple Steps<\/strong><\/h3>\n
    \n
  1. \n

    Intercept<\/strong><\/span> \u2013 Devices send DNS queries to a recursive resolver you control.<\/p>\n<\/li>\n

  2. \n

    Inspect<\/strong><\/span> \u2013 The resolver compares each domain against real-time threat intelligence curated by ThreatSTOP\u2019s Security, Intelligence, and Research (SIR) team.<\/p>\n<\/li>\n

  3. \n

    Protect<\/strong><\/span> \u2013 Malicious or policy-violating domains are returned as \u201cblocked,\u201d preventing any connection. Legitimate requests pass through without delay.<\/p>\n<\/li>\n<\/ol>\n

    Because DNS resolution happens before web, email, or API traffic flows, Protective DNS neutralizes threats earlier than any traditional firewall or endpoint agent can.<\/p>\n

    Why We Outperform the Competition<\/strong><\/p>\n

    ThreatSTOP ships more actionable protections than anyone else<\/span>. Administrators can enable over 770 discrete threat categories and policy toggles, compared to just 126 offered by our nearest competitor. Need to block a specific collaboration tool, social-media app, or cloud storage service? Our optional App Control bundle lets you do exactly that, aligning security with business policy at the click of a checkbox. More choices mean tighter policies, fewer false positives, and broader coverage against emerging threats.<\/p>\n
