Open FAIR (Factor Analysis of Information Risk) is a standardized framework designed to help organizations quantify and analyze information security and operational risk in financial terms. Developed by The Open Group, Open FAIR enables businesses to make informed decisions by providing a consistent methodology for assessing the probable frequency and impact of risk events. This model uses factors such as threat event frequency, vulnerability, and loss magnitude to calculate risk, helping organizations prioritize investments and communicate risk to stakeholders in a language they understand - money. Open FAIR is widely adopted for its ability to translate complex cybersecurity risks into clear, actionable insights that align with business objectives.
