A Site/Lab License is usually limited to a single facility within a company. A Site license utilizes a network hardware key (HWK or dongle) and is limited to a number of runtime licenses (minimum of qty 10). The hardware key is placed on a secure server, and up to the license limit of computers can launch the product(s) simultaneously.
Alternately, a Corporate License does not use a hardware key, and includes many more features, a custom build for the company, specific customization to the corporate build of SCSItoolbox, onsite training, and much more.
