Creating responsive, secure application for field agents

The SES Investigator application is a tool developed to allow law enforcement investigators to store case information in a central repository that is accessible and shared with other investigators in the task force. The main reasons that lead for the development of this new version of the Investigator application was the requirement to move from a single user version to a multi-user version that would also allow the system to be used while still in the field.

The first version of the application was a standard ASP.NET application, using heavy UI controls from Infragistics and Developer Express. While this found to be a great solution on the LAN, when the application was used in the field, it became completely unusable. After the first two versions of the SES Investigator Internet application that used standard ASP.NET and ASP.NET AJAX did not provide good enough performance over the web, the team looked for a new technology and Visual WebGui was chosen.

Using Visual WebGui enabled the SES Investigator application to finally reach the most important requirement of usability and performance in the field. "With Visual WebGui the application runs with excellent performance while under even the tightest of bandwidth constraints. Additionally, Visual WebGui's unique architecture and protocol provides secure by design applications which is extremely important when connecting via cell phone modems," said Robert Johnson, SES Investigator Project Manager.
