* **Phase 1:** Development starts with the first available dev build
* **Phase 2:** Early Availability clients within 3 weeks of OS GA
* **Phase 3:** GA release within 2 months of OS GA
**Disclaimer:** In cases where changes introduced by the OS vendor (Microsoft or Apple) prevent the existing solution from providing parts of its functionality Check Point will work with the OS vendor on restoring the capabilities, while providing full transparency to the field. No time limitations will apply in this case, as Check Point cannot control the third party.
