Symantec Advanced Threat Protection (ATP) consists of the following control points: network, endpoint, and email. Your organization can purchase one, all, or any combination of these control points that meet your needs. Install the control points that your organization purchased to have access to that functionality. For more information about licensing or purchasing additional control points, see your Symantec sales representative.
When your organization purchased ATP, Symantec sent your organization an email with the license file attached in .slf format. Click Browse to locate and upload this license file. Each standalone appliance and CIU requires a license. A CIU distributes the license to each of the scanners it manages. You must install a valid license to proceed with installation.
Only license files with the .slf extension are supported.
Symantec Advanced Threat Protection: Network 1.0 licenses are not supported.
You can view the license status on the Settings > Global Settings page in ATP Manager.
