Internet access is essential to the productivity of most organizations—but not everything on the Internet is work-appropriate or safe. From time-wasting sites to phishing domains, employees can unintentionally expose your company to productivity loss, legal risks, or cyber threats just by visiting the wrong webpage. And before you think it couldn’t happen to you or your team—even the most cybersecurity aware can be duped by emerging threats like fake CAPTCHAs or phony unsubscribe links.
That’s why blocking unwanted websites on your company network is a critical step in your cybersecurity strategy. But how can you do it without over-restricting employees or overloading your IT team?
Let’s explore the most effective and scalable ways to block unwanted websites—without the headaches.
Blocking specific websites isn’t about micromanaging employees—it’s about managing risk. Here are just a few reasons to implement web filtering:
Not all “unwanted” sites are created equal. Whether you only want to block threats, or you want to have stricter restrictions on employee Internet access, it’s important to define which categories or URLs pose a risk to your organization. Commonly blocked content categories include:
The above is not a comprehensive list of content and threat categories to block, but a great place to start thinking about the types of content you’d like to limit access to. Find a more complete list of content category options on the DNSFilter Help Center.
There are multiple ways to block websites on a company network. Here are the most common approaches:
DNS filtering blocks access to unwanted websites at the DNS level—before the connection is even established.
Benefits:
Traditional firewalls can block domains or IP addresses, but they often lack the context or categorization needed for nuanced filtering.
These can offer site blocking on specific devices but require extensive setup and maintenance. They’re also easier for savvy users to bypass.
Web content filtering isn’t one-size-fits-all. Different departments might have different needs. For example, your marketing team might need access to social media while the accounting department doesn’t.
With DNSFilter, you can create custom filtering policies to block employee access to content by:
Beyond just filtering by content or threat category, Allow and Block lists allow you to create granular policies down to the domain, subdomain, or TLD.
This customization allows you to strike the perfect balance between security and productivity.
Blocking sites isn’t a “set it and forget it” task. Threats evolve, and so do your employees’ needs.
Use your content filter’s analytics and reporting tools to monitor:
With this insight, you can fine-tune your policies and stay one step ahead of risks.

It’s important that employees understand why certain sites are blocked. Transparency builds trust and helps prevent accidental policy violations. Additionally, it’s important to give your users a way to submit requests to access content that has been unnecessarily or incorrectly blocked.
Ensure that feedback is a two-way street between your Security team and the rest of the company’s users. Provide a clear Acceptable Use Policy and include messaging in customizable block pages to let users know when and why a site is restricted, and also how to submit their requests for a site to be unblocked or recategorized.
Blocking unwanted websites doesn’t have to mean locking down your network or frustrating your users. With intelligent, AI-powered DNS filtering, you can protect your business from threats, enforce policies, and ensure a more productive digital environment.
