/// Denuvo (https://irdeto.com/denuvo/) is a family of DRM originally created in 2014 by Denuvo Software Solutions, which was acquired by Irdeto in 2018 (https://www.gamesindustry.biz/irdeto-acquires-denuvo-in-bid-to-beef-up-security-in-the-games-industry).
/// Denuvo Anti-Tamper (https://irdeto.com/denuvo/anti-tamper/) is the most common, preventing game files from being modified and requiring online activation of games.

/// Denuvo Anti-Cheat (https://irdeto.com/denuvo/anti-cheat/) is a form of anti-cheat, though information on what games use it is rather sparse.
/// It was used briefly in Doom Eternal Update 1 (https://store.steampowered.com/news/app/782330/view/2187005925152148469), before being completely removed in Update 1.1 (https://store.steampowered.com/news/app/782330/view/2187006557874536446).
/// It's somewhat difficult to find other games that may use this, as quite a few sources seem to erroneously refer to Anti-Tamper as Anti-Cheat.
