Introducing DNS filtering by Control D

Teams that want to block malicious, phishing, or unwanted destinations can set up DNS filtering rules in Control D and apply those rules to any groups, tags, or devices in their tailnet with a simple access control list (ACL) integration. And starting today, you don’t have to go through another procurement process to do so.

How it works

Add Control D as a nameserver in the Tailscale admin console, and head over to your Control D dashboard to find a default security rule (or create a custom rule). In your Tailscale ACL, map the users, groups, or devices to the Control D rule. Your devices will then send DNS queries through Control D over encrypted DNS, applying the filtering ruleset you’ve just set up.

{
  "nodeAttrs": [
    {
      "target": ["group:employees"],
      "attr": [
        "controld:o13v9z7zns",
      ],
    },
  ],
}

Tailscale will bill you for the number of users you need DNS filtering for. No need to predict how many devices, serverless nodes, or other infrastructure you’re going to have. Just let us know the size of your organization, and we’ll send you a simple user-based bill at the end of the month.

You still manage DNS filtering rules inside Control D, whether through the Dashboard or API.

Why Control D?

Control D is one of the fastest and most reliable DNS filtering services we’ve tried out (under 7 ms in North America). We already have customers using their service, and when we met the team behind Control D, we knew they were onto something great.

Control D blends threat feeds, malicious domain and IP detection, and machine learning to block malware, phishing, and suspicious domains. It’s consistently ranked as one of the top DNS malware blockers. Control D lets you filter by content categories, choose from a maintained list of over 1,000 services and apps, and write custom rules to block, allow, or redirect anything else. It gives you the same kind of straightforward control over the public Internet that Tailscale gives you inside your tailnet. Filter by recognizable domains and write custom rules to block, allow, redirect, or reroute traffic using Control D managed domain lists.
