FinOps, short for Financial Operations, is a set of practices that brings together finance, technology, and operations teams to manage and optimize cloud spending. In cybersecurity, FinOps ensures that cloud investments are secure, cost-effective, and aligned with organizational goals. By improving collaboration and transparency, FinOps helps organizations monitor cloud usage, prevent unnecessary expenditures, and implement security controls for financial data. This approach supports decision-making through real-time data, enabling teams to balance performance, cost, and security. FinOps is essential for businesses adopting cloud services, as it helps maintain financial accountability and control over cloud resources, while also addressing potential security risks associated with cloud environments.
