AdGuard

AdGuard is a popular suite of ad-blocking and privacy protection software originally founded in 2009. The brand was initially established in Moscow, Russia, but later relocated its headquarters and operations entirely to Cyprus to better serve its global user base under EU jurisdiction.

The software provides tools for blocking ads, preventing tracking, and filtering web content across various operating systems, including Windows, macOS, Android, and iOS. Ownership remains under AdGuard Software Ltd, which operates as a private independent entity headquartered in Limassol, Cyprus.
