CylanceV operating modes
CylanceVrequires a license key. There are two types of license keys: online and offline.
This license key requires an Internet connection so
CylanceVcan validate the license. Once the online license key has been validated, the Internet connection is no longer needed so long as the system is not shutdown or restarted. An Internet connection is required to revalidate the license if the
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
This license key does not require an Internet connection for validating the license. In offline mode,
CylanceVcan use a local model (DSC file) to run threat analysis. This allows
CylanceVto be used completely offline. Offline license keys will expire on a set date. After this date, a new offline license key is required.
For version 2.9, the offline license keys will expire on December 31, 2024. If you are using a previous version of
CylanceVas of December 31, 2022, you will receive a notification that your license has expired and the
CylanceVagent will not run. For more information, see KB 66137.
CylanceVdoes not require a fixed IP address. If the local model is not used, then
CylanceVwill require an Internet connection to use the
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.
