Field Search


The National Law Enforcement and Corrections Technology Center (NLECTC) has released Field Search.

Design and development of Field Search was initially funded by NLECTC,  a branch of the National Institute of Justice. It is now a cooperative volunteer project between KBSolutions, Silent Shield, and NLECTC. The software is a FREEWARE product available to justice system agencies and is officially distributed through the National Law Enforcement and Corrections Technology Center - Corrections Center of Excellence. . 

Field Search Software was developed by Jim Persinger of Silent Shield. with design consultation by KBSolutions. The software is specifically designed for Probation and Parole Officers to conduct fast and meaningful exams of offender’s computers in the field. Given changes that accompany the Vista/7/8/10® environment, Field Search may also be a viable tool for First Responders. The easy to use software comes with an 109 page manual to assist field officers in using the application. 

While designed to complement classes taught by Certified Field Search Instructors(CFSI), the software can be used by non-technical officers who have not attended the class yet wish to quickly and efficiently search an offender’s computer.
