In advance of surveillance, an activity check can uncover information pertaining to a subject's known physical activities at distinct periods of time, determining when

surveillance will be most successful. Divorce and Widow Checks are designed to ensure that subjects and/or widows are receiving benefits, as well as noting any changes in medical condition. Our field investigators are professional and courteous and represent our clients with an emphasis on integrity. 


Whether it is for a personal matter or employment. We can assist with looking up criminal, civil, commercial, or financial records.


Our team of full-time researchers is trained and proficient in examining digital footprints with cutting edge technology. Masterchek Inc can provide a cloud-based threat hunting and incident response platform that leverages live memory analysis and forensic triage methods to independently inspect and analyze hosts (workstations and servers, both physical and virtual). The data collected is enriched by software reputation and threat intelligence sources and enables investigative workflows to detonate suspicious threats for a deeper analysis.

We provide a comprehensive picture of the state of endpoints - within minutes.

This process is called Forensic State Analysis (FSA). Evidence from computer forensic investigations is usually subjected to the same guidelines and practices as other digital evidence. This evidence has been used in several high-profile cases and is becoming widely accepted as reliable within U.S. and European court systems. Studies show that businesses that face a data breach can end up losing a significant amount of revenue. Masterchek Inc can offer a real-time forensic threat detection service with on-demand incident responses. We provide a proactive approach for our clients with the

ability to expose, isolate and eliminate threats, risks, and vulnerabilities that your

prevention tools can miss.




With the current COVID-19 pandemic, finding where it started and how it is spreading is an integral part of the safety and security of where you live and the country around you. While many government and health agencies are doing their best, many have reached out to investigative agencies to help in their contact tracing efforts. 


What is Contact Tracing? Contact tracing is a control measure employed by health department personnel. It’s been used for decades and is a pivotal strategy to help prevent COVID-19 from spreading any further. As the COVID-19 virus spreads quickly, many communities need to train a larger workforce within the public and even private agencies to halt the continued transmission of the COVID-19.

Contact us regarding your DOT screening exams. We are able to conduct these exams in our office or at your facility if needed. Go to the home page and schedule your appointment.

There is nothing more unsettling than not knowing about a potential witness that the other side is calling or a juror that is on your panel. We can assist with finding out if the person is biased in any way. Investigators play a major role in many investigations. In cases that

involve criminal, domestic, civil investigations, etc, once the case reaches trial the legal team may hire an investigator to assist in preparation. Trial preparation is the gathering and preparing of information for a court case or hearing. Effective preparation help to give a

judge or jury a better understanding of the facts being presented in a lawsuit. Effective trial preparation can be essential to winning a case, so it should never be ignored.


Trial preparation includes the following:

  • Evidence gathering

  • Forensic investigation

  • Private investigations

  • Evidence analysis

  • Preparing witness testimony

  • Creation of investigation reports

  • Medical investigations

  • Criminal investigations

  • Scene Reconstruction
