Its AI-driven platform protects brands, domains, people and assets from threats outside the corporate network, including phishing, impersonation, credential theft and dark-web activity, and it also offers breach response and takedown services. Founded in 2013, it listed on Nasdaq (ZFOX) in 2022 through a SPAC and bought the breach-response company IDX that same year.
