We create technology solutions for clients and on one project we were requested to use Fortify on Demand after the client had read a good report about it. They sent us the report and recommended its use.
In this case, we were using Java to program the client's solution and so we used Fortify on Demand alongside our Java development operations, for the purpose of improving the application's security.
The work we were doing for the client involved creating a billing system that they would use to manage payments and taxes for other companies in Chile. We've only used Fortify on Demand for this one client so far.
Because Fortify on Demand was so new to us, we decided to go with the trial version first and figure out the costing at a later stage.
