Sophos Web Appliances

Sorry, this product is no longer available, Please contact us for a replacement.


Our purpose-built secure web gateway appliance makes web protection simple. It provides advanced protection from today's sophisticated web malware with lightning performance that won't slow users down. And you get full control and instant insights over all web activity on your network.

  • Protect users from new zero-day threats
  • Be up and running in just 10 minutes
  • Easily accommodates user requests and custom policies
  • Extend protection to offsite users easily
  • Email scheduled reports directly to managers
  • Deploy hardware or VMware-Ready appliances

Advanced protection from web malware

Our advanced web protection engine intelligently scans web content and blocks the latest web threats. We accomplish this by using advanced techniques like JavaScript emulation, behavioral analysis, context-sensitive inspection, and dynamic URL analysis for both HTTP and HTTPS traffic. And unlike other web gateways, you get all this protection without sacrificing any performance.

The new Sophos Sandstorm* enhances targeted attack protection, visibility, and analysis. Sandstorm complements our advanced web protection engine to quickly and accurately detect, block, and respond to evasive threats using powerful cloud-based, next-generation sandbox technology.

Granular web controls

You'll be up and running in minutes with safe web browsing policies that minimize legal and workplace concerns around inappropriate content. With just a few additional clicks you can enforce browsing quota times. And, our new granular controls for social web applications like Facebook or YouTube let you disable specific features such as chat, games or comments.

Stop rogue users and enforce safe search

In addition to blocking common anonymizing proxy sites, we also dynamically identify proxy abuse in real-time, helping you put a stop to rogue users trying to bypass corporate policy. You can also activate safe search and monitor inappropriate search terms to keep your environment safe.

Rich reporting provides unrivalled insight

Detailed reporting is standard, stored locally with no separate database servers or appliances required. Whether you need standard user-activity reports or custom reports with extensive drill down for deep forensic investigations, the Sophos Web Appliance has you covered.

Extend your protection everywhere

Add Sophos Endpoints to extend your protection everywhere users go. The endpoint provides full web protection and policy enforcement off the network, with no need to backhaul traffic or use a VPN. Policy and reporting logs sync automatically via the cloud with your web appliance, so it's like they never left the office.


Dedicated or UnifiedDedicated or Unified

With Sophos, you have your choice of a dedicated purpose-built web appliance, or a secure web gateway integrated into your UTM.

Our Sophos Web Appliance is ideal if you want an appliance dedicated to web security with streamlined workflow and policy tools. However, if you’re interested in consolidating your network security into a single appliance, our UTM with integrated web protection is for you.

Both offer all the great features below, including our unique Web and Endpoint integration to provide complete web protection everywhere.

Advanced Threat Protection

Advanced Threat Protection

With our Secure Web Gateway, you get the most advanced web threat protection:

  • Our high-performance web malware engine inspects all web traffic in real-time
  • Advanced techniques like JavaScript emulation block the latest web threats before they reach the browser
  • SophosLabs continuously updates our threat intelligence via the cloud, keeping you ahead of new and emerging threats

Real-Time Reputation FilteringReal-Time Reputation Filtering

SophosLabs identifies over 30,000 newly infected websites daily. You’re protected from all of them.

Real-time reputation filtering protects you from newly infected websites as soon as they come online. We do this using our ever-growing, cloud-hosted database of malicious sites.

Customizable Web Filtering

Customizable Web Filtering

Select from billions of sites in 56 categories to create safe web browsing policies. You can minimize legal concerns around inappropriate content and maximize productivity.

You can set policy by users and time, using a variety of authentication options including IP Address, Active Directory SSO, eDirectory SSO and LDAP.

Dynamic App ControlDynamic App Control

With our UTM web protection, you get complete control to block, allow, shape and prioritize web applications like file sharing, IM clients, streaming media and games.

Deep Layer-7 inspection identifies over 900 applications. And, you'll get feedback on unclassified applications too.

Monitor your web traffic in real time. In just a couple clicks you can maximize the bandwidth for what’s important, and minimize it for what’s not. For example, you can control YouTube and Facebook while accelerating Salesforce.

Protection Everywhere

Our endpoint protection integrates with both our Sophos Web Appliances and UTMs, providing a unique and elegant solution for protection everywhere.

We’ve integrated the full power of our web protection into our endpoints. When users leave the office, they’re fully protected on the web without having to backhaul or use a VPN to get online safely.

Policy and reporting syncs through the cloud, so it’s like they never left.

Simple ManagementSimple Management

At Sophos, simplicity is our mantra. You’ll have complete control over all the security features you need all in one place, with none of the complexity.

We've invested heavily in streamlining our interface. This way you won't have to reach for the manual every time you need to update a policy or change a setting. So you're never more than a couple clicks from completing your task.

Complete On-Box Reporting

Complete On-Box Reporting

Our built-in reporting means you’ll know exactly what's happening with your users. Fix problems fast and shape your policies, keeping your users secure while boosting network performance. And, you get detailed reports as standard, stored locally with no separate tools required.

At-a-glance flow graphs show usage trends with predefined and customizable reports, providing key web activity. Report anonymization hides user names, requiring the four-eyes-principle to unhide them.

Flexible DeploymentFlexible Deployment

Both our Sophos Web Appliances and UTMs are available as a virtual appliance or in a full range of hardware models to fit any business.

Install your dedicated or UTM secure web gateway as an explicit proxy or in transparent mode with easy Active Directory or eDirectory integration.
