Only successful scans count against your license quota.

If the scan fails due to any reason, the failed scan does NOT count towards the license usage. While the scan is running you will see the license count decrease, but eventually if a scan fails, the count will increase.

Asset Based License

Asset based license allows you to scan the same asset multiple times over the license period. 
Example, If you have 5 Asset based licenses you can scan those 5 IPs N number of times till license period.
The table below summarizes the license usage for various types of scans (Domain, Database etc. ) for Asset Based license type.

Scan Type Asset Based Licenses License
Domain Machines 1 Domain IP = 1 asset license
Regardless of any number of drives on that computer		 F
Database Servers 1 Database Instance* = 1 asset license S
Exchange Servers 1 Mailbox server = 1 asset license E
Unix/MAC/AIX/Linux 1 IP = 1 asset license F
Office 365 Email 1 Email address = 1 asset license M
Office 365 OneDrive 1 OneDrive mailbox = 1 asset license D
Office 365 SharePoint 1 SharePoint mailbox = 1 asset license P
Amazon S3 1 S3 Bucket = 1 asset license F
On Premises SharePoint 1 Home URL = 1 asset license S
IMAP Email 1 Email address = 1 asset license F
File Share 1 File Share = 1 asset license F


Database Instance

  1. An instance could mean a Server or IP address.
  2. If 1 IP address/Server hosts 1 database instance, it counts as 1 scan/asset.
  3. In case of multiple database instances running on 1 IP/Server, each instance counts as a scan/asset.
    For e.g. let’s assume that on one host (10.84.222.1) running 2 named instances “application1” and “application2”, then each will require a separate scan or asset based licenses.

Exchange Server

You need 1 license per Exchange Mailbox server regardless of number of mailboxes present on the server.

Office 365 Email Scan

For Office 365 email scanning, each email scanned consumes one asset-based license

Office 365 OneDrive Scan

In the case of Office 365 OneDrive scanning, each Drive uses one asset-based license.

Office 365 SharePoint Scan

In the case of Office 365 SharePoint scanning, each URL uses one asset-based license.

File Share Scan scenarios:

There are various ways to scan a File Server where the one physical server or SAN or NAS may contain various Windows or CIFS file shares.

If you have a File Server or File Share which provides multiple shares to connect (either based on User share or Department shares) and you use the File Share scanning method to scan the individual file shares, each share and scan will count as 1 scan or asset license against your license quota.

1 UNC – 1 Scan or 1 Asset license

e.g.

\\server1\share1 = 1 Asset license

\\server1\share1\subshare1 = 1 Asset license

\\server1\share2 = 1 Asset license
