Considering TCO helps in understanding what about a security control?

Total Cost of Ownership (TCO) provides a comprehensive view of the total costs associated with implementing and maintaining a security control over its lifecycle. This includes not just the initial purchase price or setup expenses but also accounts for ongoing costs such as maintenance, support, training, and any potential operational disruptions caused by the implementation of the control.

When evaluating TCO, understanding the recurring expenses is crucial as it allows organizations to assess the long-term financial implications of their security investments. This holistic approach facilitates better budgeting and more informed decision-making regarding resource allocation for security measures. By focusing on all costs associated with a control, rather than just a single aspect, organizations can gain insight into the actual financial burden or value that a security control brings over time, ensuring that they make strategic choices that align with their risk management objectives.
