Web content filtering is a necessity in the enterprise. It’s a second line of defense if a false-negative message reaches a user’s inbox.
Must-Have Features in a Web Content Filter Solution
Before choosing a solution, it’s important to have specific features that effectively block malicious websites. Administrators must be able to configure the solution so that they can whitelist specific websites in case it’s necessary for job productivity. Most solutions have their own value-added proposition, but without the necessary features, a solution can be unreliable and won’t fit into your organization’s culture.
A few necessary features every web content filtering solution should have:
- Phishing and social engineering security: A good content filtering system blocks websites known to be a part of common attacks and owned by known cyber-criminal groups.
- Compliance: Depending on your industry, the organization is bound by specific compliant regulations. The web content solution you choose should be compliant with local laws and regulations.
- Follows company policies: The solution that you choose should fit into your corporate culture and security policies to avoid interruption of user workflows.
- Block streaming services: Most organizations do not want to allow streaming while working, so administrators must be able to block common sites.
- Torrent blocking: Administrators should be able to configure a solution to block content browsing and illegal file-sharing sites.
- Adult content blocking: Whether it’s illegal content or inappropriate content, administrators must be able to configure a solution to block content based on categories.

Types of Web Content Filters
Not every web content filter is built the same, and one distinguishing factor is the way a solution is deployed. If you choose the wrong type of solution, it can be difficult to deploy or may take additional resources and costs to support it. The types of web content filters are based on where the solution is installed.
The four types of web content filters are:
- Client-based: Administrators install the solution on the local client machine, and it runs when the user connects to the network. Although this is not a good enterprise strategy, it’s best for small offices that don’t have the IT staff to support other types.
- Server-based: The solution is installed on a central server, and all web traffic is first routed to the server and validated with the content filter database. It’s beneficial for mid-sized offices where administrators prefer local hosting instead of cloud-based solutions.
- Gateway-based: Similar to a server-based solution, a central gateway server hosts the web content filtering solution where client internet traffic exits the network.
- Cloud-based: This deployment solution is the most preferred by managed service providers and enterprise organizations. Web content filters are provisioned to the cloud where DNS lookups are performed and domains blocked.

Common Business Requirements for Web Content Filters
Features are important, but businesses also have their own specific requirements. Some requirements are common across all industries, and your organization likely has the same concerns.
A few common business requirements:
- Pricing: Although the cost of a solution is not often a top priority, it still must fit into your IT budget.
- Scalability: Your organization might have only a few dozen employees now, but it could have hundreds in a few years. Web filtering solutions should be able to scale with your growing company, or you must spend money to replace it in the future.
- Flexibility: Not every organization has the same requirements, so a web content filter must provide configurations to make it flexible for any organization. The solution should include access controls, granular configurations, and custom whitelists and blacklists.
- Compatibility: A cloud-based solution is generally compatible with any environment, but any solution you choose should have the ability to incorporate seamlessly into your own environment.
- Dynamic database updates: Every day, new threats are created on the internet. A web content filter should have the ability to update frequently to include the latest threats detected in the wild. These updates should be automatic without administrator intervention.
- Easy to manage: Too much administrator overhead puts stress on IT staff and costs money in lost productivity. Your chosen solution should be easy for administrators to maintain and continue to configure as the business environment changes.
- Reporting: Stakeholders need to know that their investment is giving them a return on their investment. Administrators should be able to run reports and review them for any possible targeted attacks on the organization.
