Why URL Filtering Matters

Threats Hide Inside Everyday Browsing

Data threats have become smarter than ever — residing within malicious websites designed to expose data assets, leak them, or encrypt them for ransom. Users spend increasing time on the web for both personal and business use, and unfettered web activity exposes organisations to security and business risks: malware propagation, data loss, and compliance gaps.

Productivity Drain

Hours per employee per day on non-business sites — entertainment, social media, shopping. Real impact on output, especially on shift-based or operational teams.

Inappropriate Content

Workplace exposure to objectionable content creates HR risk and compliance exposure, especially for regulated industries with mandatory acceptable-use policies.

Bandwidth Strain

Streaming, video, P2P traffic chokes business-critical bandwidth. Shift bandwidth back to applications that actually drive revenue.

Hosted Malware

Modern malware hides in compromised legitimate sites. Phishing pages mimic banks and brands. URL category filtering catches these patterns before users click.

How It Works

85+ Categories, Updated in Real Time

URL Filtering works by maintaining a highly categorised database of websites at the GajShield Threat Lab — allowing or disallowing access either at all times or on time schedules. Policies are configured through GajOS Bulwark's easy policy interface.

A website can sit in a single category or multiple categories. Block sites categorised as sports or gambling, allow Business or Productive categories — all in one policy rule. Categorisation happens in approximately 100 milliseconds, with local databases automatically updated alongside the central database.

Categorise

Domain identified, mapped to one or more of 85+ categories within ~100ms.

Apply Policy

Allow, block, or rate-limit based on user, group, time of day, file size restrictions.

Log Everything

GajOS Bulwark logs every URL access decision — for audits, investigations, and compliance.

Key Capabilities

Five Pillars of URL Filtering

01

Allow or Block by Category

URL filtering identifies the domain and categorises it for action based on your policy set. One rule covers thousands of sites in a category.

02

Custom Categorisation

Custom filtering by keyword and domain name. Create your own categories to allow or restrict specific sites for specific business needs.

03

Real-Time Categorisation

URL filtering categorises websites in approximately 100 milliseconds. Local databases update automatically alongside the central database.

04

Multi-Protocol & MIME Support

URL filtering supports HTTP and HTTPS protocols, MIME type filtering, and file extension blocking — complete control over what enters via web traffic.

05

Complete Visibility

GajOS Bulwark maintains a complete log of all URL filtering activities and actions taken — with user and contextual information for investigation.

All Capabilities

In One Policy Framework

Same policy editor handles URL filtering, application filtering, DLP, and IPS — one place to define, one place to audit.
