Getting started with Web Control

Page updated

April 17, 2024


Latest changes

With the April 2024 release, we've released a major update that our customers have been asking for. Web Control no longer requires Real Site to filter browser traffic (the devices must run AV and agent versions 24.2 or later).

If you choose to turn off Real Site, your DNS requests will be resolved according to your standard network settings, and your managed devices will be able to access domains on your internal network.

Additionally, compatibility with Avast VPN has been vastly improved, and Web Control can now be used with Avast VPN enabled.

About Web Control

Web Control is our latest managed web content filtering solution available in the Avast Business Hub. It operates on two distinct levels:

  1. Web content filtering: Administrators can define web content categories, as well as specific domains and subdomains, to regulate access from their managed devices. This feature helps prevent users from browsing or downloading content that's unrelated to work, or content that's potentially dangerous, inappropriate, or harmful. Moreover, it assists in stopping the upload of sensitive data to file-sharing web services.
  2. An additional layer of security: Web Control acts as an added layer of security during web browsing. It blocks devices from accessing malicious domains* even before the standard Web Shield protection activates.

* As determined by Avast’s web categorization engine.


🚀 Quick start guide

You can start using Web Control right away, provided your devices run Premium or Ultimate Business Security. Please follow the steps below:

Before you start, please make sure that Web Shield is enabled in the policy applied to the particular device. Also, upgrade Avast Antivirus on your devices to version 24.2 or later.
Go to Devices (if you don't see the Web Control column in the Device list, click on the icon on the right side of the table header and tick the box to show 'Web Control').
Select devices where you want Web Control to be installed.
Select ⠇ More › Manage services › Enable Web Control.
Restart the devices (this requirement will later be removed).


Service components 
Policies Reports Devices

Under the Settings tab within each policy, there's a new tab labeled Web Control. It gives the admin the following options:

  • Allow or block certain categories
  • Allow or block certain domains/subdomains
  • Check how a particular domain is categorized
  • Add contact details to the block page displayed to end users, should the user feel they should be allowed to access certain websites

Your reports page (site view for multi-tenant Hubs) now contains the new Web Control report. It provides insight into the browsing behavior of the managed devices.

  • The history of requested domains remains accessible for 90 days (rolling)



A new column labeled Web Control shows the status of the service on each device.

  • Click on a specific device to see the device detail. There's a section called Web Control. 

ℹ️ Please be aware that each access to the device detail is logged, and there's a UI prompt informing you about this. Ensure that you are legally permitted to view the browsing details under your local laws.

This protects you in case authorities require you to demonstrate that you haven't invaded privacy of people using the endpoint devices beyond what the applicable law permits.

Alerts Dashboard Block page

Admins can choose to receive an alert when a malicious website has been blocked by Web Control.

Web Control alerts can be accessed from Hub UI. Email alerts will be added soon.

The Web Control dashboard widget is displayed on any site dashboard where Web Control can be activated.It shows the number of requests blocked, either based on your rules or because the particular domain has been tagged as dangerous by us.


When a user tries to visit a blocked site, a block page loads in their browser instead. The admin can add their contact info to the block page ('Customize your block page' section in Web Control policy settings) and give users the chance to contact them in case they feel the particular page shouldn’t be blocked.


System requirements
  • Avast Premium Business Security or Avast Ultimate Business Security subscription managed from Business Hub
  • Endpoints running Windows 7 or later 
  • Endpoints running Avast Business Antivirus 23.10 or later, agent 23.6 or later
  • Web Shield active
  • Real Site active (not required with AV and agent 24.2 or later)
  • Firewall – Enabled UDP 53 DoH, TCP 80, TCP/UDP 443, TCP 7500; *, *

Unsupported systems

  • Mac – coming later
  • Server systems


💡 Good to know:

  • Web Control works with many major browsers: Chrome, Firefox, Edge, Internet Explorer, Opera, Waterfox, Hero Browser, QQ Browser, Yandex Browser, Spark, Maxthon, Vivaldi, Brave, Sogou (+ partial support of Avast browsers, due to them using their own DNS and built-in VPN)
  • Web Control works in browsers and doesn’t block connections initiated by other applications
  • We recommend password-protecting your endpoint Avast installations. Otherwise the end user can turn Web Shield and/or Real Site off locally and circumvent Web Control


Good to consider
  • Domain filtering: Websites visited by your users may ping additional domains in the background. We're working to filter these out from your reports as effectively as possible. Please tell us how it works for you.
  • VPN compatibility: Avast VPN may interfere with Web Control efficacy.
  • Real Site: Web Control doesn't require Real Site to deliver its web filtering functionality anymore, provided your devices run Avast Antivirus and Business Hub agent 24.2 or later.

Do you encounter any issues deploying Web Control? Below are a few points you might want to check. Again, we're keen to hear your feedback

  • The target device runs AV 23.10 or later
  • The target device has Web Shield turned on
  • The allow/block definition may not apply instantly. Ensure your browser cache has had sufficient time to clear. A device restart may help.
