Control desktop, laptop, and mobile device access to malicious and inappropriate internet domains with Comodo Dome Shield DNS filtering.

Malware and inappropriate content are just a click away.

There are links to "bad" websites everywhere, and attackers use a variety of tactics to lure people into clicking them. And there are plenty of sites that, while not malicious, are inappropriate for one reason or another. Comodo Dome Shield DNS filtering protects your users—even their mobile devices when they're on the go—from accessing these problem sites.

DNS filtering is available for homes, businesses, and MSPs. And best of all, no matter how many users you have, it's completely free.

Key capabilities

  • Flexible: Create security rules to block web threats, build your own black/whitelists, and block categories of websites.
  • Smart: Protect data when users are mobile by securing sensitive information, such as credit card numbers, when used on public networks.
  • Fast: By changing your DNS settings to Dome Shield's DNS, you can speed up browsing for your users.
  • Easy to set up: With the easiest setup available on the market, you'll be up and running within minutes.
  • Free forever: Sometimes you do get more than what than you pay for.

For the Home

Kids may be more digitally savvy than their parents, but that doesn't mean they know best when it comes to surfing the internet. Keep your family, your computers, and your mobile devices safe. DNS filtering lets you make the rules.

Secure Browsing

Comodo Dome DNS filtering makes it easy to restrict web browsing based on the category and security rules that you set.

Parental Control

It's not just about security. There are some websites you just don't want your children to be able to access. DNS filtering lets you do just that—and it provides a "teachable moment" with the ability to create block pages with customized messages telling them why they can't get to those sites.

Faster Internet

You don't just get safer browsing, you also get speedier browsing. Changing your DNS settings to Comodo Dome Shield DNS filtering will give you quicker internet access.

For the Business

Your employees are smart, but they're not all cybersecurity experts. Training is important, but it's not a silver bullet. DNS filtering keeps your users productive with safe and appropriate internet browsing.

Web access control

Blocking users from malicious—and even inappropriate or productivity-killing—sites has never been easier. The ability to create granular web access policies per device and per network keeps you in control.

Off-network protection

The endpoint agent for roaming laptops, along with mobile apps for iOS and Android, means your users are secure, even when they're on the road.
