Frequently asked questions

Content filtering is the practice of controlling access to certain types of online content, such as adult material, gambling sites, or malicious domains. It helps organizations maintain security, productivity, and compliance.

DNS content filtering blocks unwanted websites before they load by stopping DNS requests to restricted domains. This makes filtering faster, more reliable, and harder to bypass than browser plug-ins or endpoint-only solutions.

The terms are often used interchangeably. Content filtering focuses on blocking categories of online content (adult, gambling, malware), while web filtering typically refers to broader control over internet access, including URL- and service-level rules.

Without content filtering, employees and guests can accidentally (or intentionally) access inappropriate or dangerous content. This increases the risk of malware infections, compliance violations, bandwidth waste, and productivity loss.

Yes. In addition to category-based blocking, Control D offers service-level filtering with over 1,000 popular apps, tools, and platforms you can block, allow, or redirect.

By blocking distractions such as streaming platforms, social media, and gaming sites during work hours, employees stay focused on business-critical tasks, boosting overall productivity.

Absolutely. Control D allows admins to create policies for different groups — for example, strict filtering on guest Wi-Fi while giving the marketing team access to social media.

Yes. Many industries (finance, healthcare, education) require controls to prevent access to inappropriate or non-compliant content. Control D's policies help organizations meet regulatory and internal compliance standards.

Not easily. Because filtering occurs at the DNS level and is managed via the cloud, it’s much harder to bypass than browser extensions or endpoint tools. Admins maintain centralized control.

Deployment takes minutes, not days. With no hardware or complex setup required,Control D works across your network, remote teams, and guest Wi-Fi right out of the box.
