A legacy OS is one that no longer receives support from the manufacturer.
CylancePROTECT installed on a legacy operating system does not receive product feature enhancements, bugfixes and security updates from the BlackBerry Engineering team.
The reasons for this are as follows:
· Technological burden: These operating systems are old and no longer support the necessary framework or technologies that BlackBerry requires to continue improving and innovating the product.
· Manufacturer Deprecation: The operating system is no longer supported by the manufacturer. This lack of support could expose serious security flaws or bugs that will not be addressed by the manufacturer.
