We love the power PDFfiller gives us to export data filled in to be exported to Excel and manipulated. For the most part, it is a very intuitive program. There are some aspects of set up that are confusing, but customer support is GREAT, QUICK, and seemingly PATIENT. We are very happy so far with its performance.

It's easy to work with. Wish there was a "clear all" button so that I wouldn't have to close and open back up to start a new form, but overall, great product

Application control is a security practice that blocks or restricts unauthorized applications from executing in ways that put data at risk. Application control includes completeness and validity checks, identification, authentication, authorization, input controls, and forensic controls, among others.
Application security is the process of making apps more secure by finding, fixing, and enhancing the security of apps. Much of this happens during the development phase, but it includes tools and methods to protect apps once they are deployed.
Application controls can be classified into three major categories, processing controls and output controls.
On the whole, general controls apply to all computerized applications and consist of a combination of hardware, software, and manual procedures that create an overall control environment. Application controls are specific controls unique to each computerized application, such as payroll or order processing.
