Citect SCADA supports two different software licensing models:
Never trust client‑side data. All validation must be re‑checked on the server.
The tool gained significant popularity among the cybersecurity community for its simplicity and effectiveness. When active, Tamper Data prompts the user with a dialog box every time the browser attempts to communicate with a server. This pause gives the user the opportunity to examine the request details and alter them. For example, a tester might change a price value in a hidden form field or modify a session cookie to see how the server responds to unexpected input. tamper data

FLEXERA Softkey Licensing
The FLEXERA softkey solution stores license information on a FlexNet Enterprise License Server. The Citect SCADA client process will retrieve licenses from this server as required by the Citect SCADA system. To activate and administer licenses, you use the Floating License Manager (see Activate Licenses Using the Floating License Manager).
In both cases, Citect SCADA uses a Dynamic Point Count to determine if your system is operating within the limitations of your license agreement. This process tallies the number of I/O device addresses being used by the runtime system.
A point limit is allocated to each type of license included in your license agreement. These license types include:
A special OPC Server License is also available if you want to run a computer as a dedicated OPC server. For more information, contact Technical Support.
If required, you can specify how many points will be required by a particular computer (see Specify the Required Point Count for a Computer).
Note:
• There is no distinction between a Control Client and an Internet Control Client.
• There is no distinction between a View-Only Client and an Internet View-Only Client.
