AutoSTIG is a suite of Open Source software developed by Netizen that drastically reduces the amount of manual work involved in verifying Defense Information Systems Agency (DISA) Security Technical Implementation Guide (STIG) compliance. AutoSTIG assesses VMWare, Windows 10, Windows Server 2016, and other systems for current STIG compliance. This tool reduces the amount of time needed to validate a target system by as much as 85% while avoiding human error and integrating seamlessly with reporting tools such as eMASS.
AutoSTIG was recognized by FedHealthIT Magazine as being a "top 5 disruptive technology" for the federal government market and was developed to support cybersecurity engineering and NIST RMF assessment efforts for the U.S. Army. It is in current use by multiple DoD components for helping achieve Authorization to Operate (ATO) in record time by reducing the time to perform STIG checks from hours to mere minutes.
