Frequently asked questions
DNS filtering is a security method that blocks access to unwanted or harmful websites at the DNS level. When a user tries to visit a site, the DNS request is checked against filtering rules, and access is allowed or blocked based on policy.
When you type a website address, DNS translates it into an IP address. DNS filtering intercepts this request and blocks it if the domain matches a restricted or malicious category, preventing the connection before any data is exchanged.
DNS filtering protects against malware, phishing, and ransomware, while also giving organizations control over employee internet usage. It reduces risk, improves productivity, and helps with compliance.
DNS filtering is the broader framework — it blocks or allows domains at the network level. Content filtering is more specific, focusing on categories of content such as adult, gambling, or streaming. Together, they provide layered control.
Yes. By blocking known malicious domains before they load, DNS filtering prevents users from reaching phishing pages, malware download sites, or command-and-control servers.
Absolutely. Cloud-based DNS filtering covers employees anywhere — in the office, at home, or on public Wi-Fi — without needing hardware appliances.
Control D offers category-based rules, service-level filtering for 1,000+ apps, and custom domain rules. Policies can be applied per network, device, user, or department.
Yes. Many regulations require organizations to control access to certain categories of content. DNS filtering helps demonstrate compliance with standards in finance, healthcare, education, and other regulated industries.
