AdGuard

AdGuard is a software brand and suite that develops ad blocking and privacy protection tools for consumers. Its products aim to block online advertisements, tracking scripts, and malicious content across browsers and apps while offering configurable filters and parental controls.

In addition to browser extensions and standalone apps, AdGuard operates AdGuard DNS and AdGuard Home, which provide network-level blocking that can be deployed on home networks or servers. Desktop applications for Windows and macOS filter traffic locally and support custom filter lists created by AdGuard or third parties. Mobile apps for Android and iOS use a system-wide filtering approach, typically via a VPN-based mechanism, to extend protection across devices.

Platforms include Windows, macOS, Android, and iOS; and the network-focused offerings AdGuard DNS and AdGuard Home.

Founded in 2009, AdGuard is developed by AdGuard Software Ltd. The company offers free versions with core blocking capabilities and paid Premium licenses that unlock advanced features such as enhanced privacy controls and family protections.

AdGuard is widely used as a complement or alternative to built-in ad blockers, and it is generally described as a comprehensive, cross-platform solution.
