How to choose browsers & extensions tools
Browsers and extensions cover the software people spend most of their working day in, with a focus on privacy, tab organisation and blocking ads, trackers and malicious content. For IT teams the browser is also a managed application that needs policies, extension control and updates. This category sits apart from password managers and endpoint security, even though browsers increasingly overlap with both through built-in protections.
Who uses these tools
- IT admins standardising browsers across managed devices
- Privacy-conscious users reducing tracking and ads
- Knowledge workers juggling many tabs and workspaces
Capabilities to compare
- Built-in tracker, ad and fingerprint blocking
- Filter list support and custom blocking rules
- Workspaces, vertical tabs and split views
- Enterprise policies and extension allowlists
- Sync of bookmarks and settings across devices
Operating considerations
- Rendering engine compatibility with internal web apps
- Extension permissions that can read every page
- Central policy management for fleets
- Update cadence and security patch speed
Selection checklist
- Test your internal and line-of-business web apps in the browser before allowing it company-wide.
- Check which enterprise policies can be enforced through your device management system.
- Review each extension's requested permissions and allow only those your security team has approved.
- Confirm how quickly security updates ship and whether they can be enforced automatically.
What belongs in this category: A product fits here when it is a web browser or a browser extension whose main purpose is privacy, content blocking or browsing productivity, rather than a standalone security agent.

Typical use cases
- Blocking ads and trackers across an organisation's browsers
- Organising research tabs into separate workspaces
- Reducing malvertising risk on shared support workstations
- Standardising one managed browser on new laptops
Trade-offs to model
- Privacy-first browsers block more by default, but some sites and internal apps break until exceptions are added.
- Content blocking in an extension works across browsers, while built-in blocking avoids extension permission risks.
Common mistakes
- Allowing users to install any extension, including ones that later change owners and turn malicious.
- Rolling out a new browser without checking single sign-on and web apps that depend on a specific engine.
