US digital media and internet company (formerly J2 Global, renamed 2021). Its cybersecurity arm owns IPVanish, StrongVPN, Encrypt.me, SugarSync and VIPRE, bought largely from StackPath in 2019. The same group publishes PCMag, Mashable, CNET, ZDNET and Lifehacker, which review VPNs. A strategic review launched in 2025 led to the sale of its Connectivity unit (Ookla/Speedtest) to Accenture in 2026; further divisional sales were under consideration.
Ziff Davis, Inc. owns VPNs and also 5 review sites that rate VPNs. Those sites may favour its own brands.
Court records published in 2018 showed IPVanish supplied a user's name, email, real IP and connection times to US Homeland Security in a child-abuse investigation, despite marketing itself as no-logs. This predates StackPath and Ziff Davis ownership. source
