What is a realistic approach to preventing all threats cost-effectively?

A realistic approach to preventing all threats cost-effectively is indeed an impossible task. The essence of risk management lies in understanding that while measures can be implemented to mitigate risks, achieving absolute prevention of all potential threats is unfeasible.

In the context of businesses and organizations, threats can vary in nature—ranging from cybersecurity threats to operational risks—and typically require different strategies and resources to address. Realistically, organizations must prioritize their resources toward the most likely and potentially damaging threats rather than attempting to eliminate every conceivable risk.

Cost-effectiveness comes into play when considering the balance between the costs of implementing security measures and the value of the assets being protected. As a result, organizations often adopt a targeted approach focused on major threats—rather than an all-inclusive prevention strategy—which ultimately reinforces the idea that complete prevention of all threats is not achievable.

Understanding this limitation helps businesses to develop more effective risk management strategies by accepting that risk can be mitigated but never fully eliminated.
