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 are usually subjected to the same guidelines and practices of 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.
