AdGuard Software Limited develops a line of ad blocking and privacy protection software for blocking pop-ups, banners, and web tracking, obscene content, malware and phishing. Some of AdGuard products are open-source, some are free, and some are shareware. Some products support Microsoft Windows, Linux, OS X, Android and iOS. A cross-platformutility, AdGuard is also available as an extension for the most widely used browsers, Firefox, Google Chrome, Opera, Safari, Yandex Browser, and Microsoft Edge.[1]


AdGuard products include:

AdGuard Home[edit]

AdGuard Home acts as a recursive DNS resolver, which responds with an invalid address for domains that appear in its filter lists quests.[2] It is analogous to Pi-hole.

AdGuard Browser extensions[edit]

The browser extension blocks video ads, interstitial ads, floating ads, pop-ups, banners, and text ads.[3] There is a possibility to handle anti-AdBlock scripts.[4] The product also blocks spyware and warns users of malicious websites. AdGuard Content Blocker is an additional browser extension for browsers Yandex Browser and Samsung Internet, which uses Content Blocker API. It downloads filter list updates and asks browsers to enforce them via Content Blocker API.

AdGuard applications[edit]

AdGuard has Windows; Android and Mac versions,[5] as well as native mobile versions for Android[6] and iOS.[7] The application sets up a local VPN, which intercepts and filters all traffic on the mobile device without sending it to a remote server.

AdGuard DNS[edit]

AdGuard hosts multiple free public DNS servers. Some of these servers provide DNS-level network filtering for blocking domains used for delivering advertisement, online tracking, analytics. The product supports encryption technologies, including DNSCrypt, DNS over HTTPS, DNS over TLS and DNS-over-QUIC.[8] AdGuard DNS also comes with an optional 'Family Protection' mode for blocking access to websites with adult content as well as enforcing safe search in search engines.[9]

AdGuard began testing DNS service back in 2016, and officially launched it in 2018.[10]


While the company's products have earned positive feedback in several industry publications,[11] a series of policies by Google and Apple app stores occurred in 2014 - 2018, which impeded user access to AdGuard's mobile applications.

Macworld mentioned AdGuard for iOS in a list of five 'best adblockers for iOS'.[12]

In April 2020, Android Central stated that AdGuard uses 'a little more processing power to do its thing than uBlock Origin', but it is 'the best all-in-one blocking tool for someone who doesn't want to use more than one extension' because it blocks cryptomining. However, Android Central recommended uBlock Origin with a dedicated cryptomining blocker over AdGuard.[13]


AdGuard developers have taken up non-commercial research in order to inform wider audiences on user privacy, cybersecurity and data protection. The following issues are notable cases involving the developers:

Adguard Ad Blocker Mozilla

  • Top-ranked websites involved in cryptojacking[14][15][16]
  • FacebookAd Network widespread distribution[17][18]
  • Fake adblockers[19][20]
  • Popular Android and iOSappprivacy issues[21][22][23][24]


  • Distribution of AdGuard for Android was discontinued by Google Play at the end of 2014. It nevertheless is still being updated and has been made available for download from the developers’ own website.[25]
  • AdGuard for iOS has not been updated since the summer of 2018 due to Apple policies against ad blocking, though it was still present in the Apple App Store.[26][27][28] In summer 2019, access to the updates of AdGuard's earlier edition for iOS was restored.[29]
  • In September 2018, AdGuard was hit by credential stuffing attack. AdGuard claims that their servers were not compromised and instead attackers used credential pairs reused by victims on other sites and stolen from those other sites. According to company spokesperson, they 'do not know what accounts exactly were accessed by the attackers', so the company had reset passwords for all accounts 'as a precautionary measure'. Also, AdGuard pledged to use 'Have I Been Pwned?' API to check all new passwords for appearance in known public data leaks. Furthermore, they implemented a more strict password security requirements.[30][31][32]

In November 2020, Microsoft Edge Store was infiltrated with fraudulent add-ons resembling add-ons for AdGuard VPN and few security products.[33]
