See below for the official notification from Cylance Support.

CylancePROTECT® and macOS Mojave
What: The macOS CylancePROTECT Agents version 1494 and lower are not compatible with macOS 10.14 (Mojave). Systems running macOS 10.14 and Agent 1494 (or lower) will experience a deadlock.

During testing and evaluation of CylancePROTECT for the upcoming macOS 10.14 release, Cylance found a change in the libraries that CylancePROTECT uses to integrate into the operating system. This change can cause a deadlock in the operating system.
When: macOS Mojave is scheduled to be released on Monday, September 24, 2018.
Affects: macOS CylancePROTECT Agents version 1494 and lower.
Recommendation: Do not upgrade systems to macOS 10.14 until CylancePROTECT Agent 1500 is released.
CylancePROTECT Agent 1500 is scheduled to be Generally Available (GA) in late October 2018.
