Beyond the conversation

ZoneAlarm by Check Point

Your digital world deserves another layer of protection.

QuantumChat protects your conversations. ZoneAlarm by Check Point extends the offering to your device: browsing, networks, apps and files. Complementary areas of security, a broader perspective.

ZoneAlarm Mobile Security

Protection for iOS and Android against fraudulent links, risky Wi-Fi networks and other mobile threats.

ZoneAlarm Extreme Security NextGen

Multi-device protection for computers and mobile devices, with features that vary by operating system.

Both products will be offered alongside QuantumChat. Plans, licences, devices and activation will be detailed at launch. Features vary by system. This does not replace conversation encryption or guarantee absolute protection.
