Our verdict on InterSafe WebFilter
InterSafe WebFilter is an on-premises web and URL filtering product for businesses, government organizations, and educational institutions. It controls client web access through proxy or ICAP deployments and a categorized URL database. Administrators can apply category-based and URL-based rules, create custom categories, enforce SafeSearch, schedule filtering actions for users and groups, restrict search and web-posting keywords, decode HTTPS traffic, and retain access logs. It is designed for Windows Server and Red Hat Enterprise Linux environments, with support for Chrome, Microsoft Edge, proxy, and ICAP environments.
Its strongest fit is an organization that needs policy control tied to existing directory and proxy infrastructure. The published integrations include Active Directory, Oracle Directory Server, OpenLDAP, Blue Coat Systems SGOS, Squid, A10 Thunder, and BIG-IP. That combination supports deployments where filtering policies need to reflect user or group identity rather than only device or network location. The product also offers multiple deployment modes and user-defined URL rules, giving administrators room to tailor controls beyond the categorized database. Buyers should assess their current proxy and directory architecture before choosing it, because its value is closely tied to that environment.
Pricing is paid and organized around 1–5-user contracts with one-year, two-year, three-year, and five-year terms. The one-year plan includes the software, URL database use and updates, and support; the longer plans show a multi-year contract price per year. The product page advertises a 5-year contract discount. InterSafe WebFilter suits organizations that prioritize on-premises filtering, directory integration, scheduled policies, and HTTPS inspection. It is less suitable for buyers seeking a free plan, AI features, or more extensive activity reporting, or for teams that prefer a cloud-first filtering service.
