Return on Security Investment (ROSI)

Definition

Return on Security Investment (ROSI) is a financial metric used to evaluate the effectiveness of security investments by measuring the anticipated or realized benefits relative to the costs incurred. This metric helps organizations determine whether their cybersecurity measures provide sufficient value in protecting their assets and reducing risks, ultimately aligning security expenditures with business goals and enhancing overall decision-making processes.
