CylanceV network requirements
CylanceVdoes not require a fixed IP address.
CylanceVcan use a local model (DSC file) and not require an Internet connection to run threat analysis (but does require an Internet connection to validate the license). If the local model is not used, then

Cylancecloud model. Using the cloud model requires either HTTP over port 80 or HTTPS over port 443. The DNS name for the
Cylancecloud model is api2.cylance.com.
It is highly recommended to allow HTTPS traffic to the
Cylancedomain or to *.cylance.com over port 443. Contact support with any questions.

CylanceVexecutable is stopped and then restarted or the device running
CylanceVis turned off and then back on. An authorization failed message displays when launching the
CylanceVexecutable if it cannot connect to the Internet and validate the license. To resolve this issue, ensure the device can connect to the Internet and then re-launch the
