How to Block a Website on Your Office Network

Knowledge Base · 2026-03-23 · by Cybergate Technology

Use your firewall

A business firewall (such as Fortinet) can block sites by category or URL for the whole network, with reporting. This is the most robust and manageable method.

DNS filtering

Services like a DNS filter block sites by category (gambling, adult, malware) before they load, and are quick to set up across the network.

Router-level blocking

Many business routers allow basic URL or keyword blocking - useful for small offices but less granular than a firewall.

When you need help

For consistent, reportable web filtering across the office and remote staff, Cybergate configures firewall and DNS-based filtering as part of managed IT.
