Net Present Value (NPV) is a financial metric used to evaluate the profitability of an investment or project by calculating the present value of expected future cash flows, discounted at a specific rate. In cybersecurity, NPV helps organizations assess the financial impact of security investments, such as new technologies or risk mitigation strategies. By comparing the NPV of different projects, decision-makers can prioritize initiatives that offer the greatest return on investment, factoring in both costs and anticipated benefits over time. A positive NPV indicates that the projected earnings exceed the costs, making the investment financially viable.
