OpenGRC is a cyber Governance, Risk, and Compliance web application intended for use by small businesses and teams. This is not intended to replace large-scale GRC Platforms, but it just might for your usecase. OpenGRC provides a resource for those who need to manage a security program but can't manage the price tag and complexity of alternatives.
Above all, OpenGRC is written to solve cyber compliance headaches that tend to be caused by complex enterprise solutions. It doesn't have to be that hard!
