The Cybersecurity Budget Trap: Are We Funding the Biggest Risks or the Loudest Ones?

Imagine a company spending ₹50 lakh on a new security tool because a vendor promises better threat detection. Meanwhile, a critical business application remains exposed because nobody has allocated funds to fix an outdated system.

Is the organization investing in cybersecurity—or simply buying the appearance of security?

This hypothetical example highlights a challenge many security leaders face: limited budgets, competing priorities and constant pressure to adopt new technologies.

As cybersecurity leaders, we must look beyond the number of tools deployed and ask a more important question: Which investment will reduce our most significant business risks?

Consider three hypothetical situations.

Scenario 1: The expensive tool :- A company considers buying another security platform. Before approving the investment, the CISO discovers that existing tools already provide similar capabilities, but they are poorly configured. Improving the current setup may deliver better protection at a lower cost.

Scenario 2: The overlooked vulnerability :- A critical vulnerability affects an old application supporting an important business process. Fixing it is expensive and disruptive. Rather than prioritizing solely by its technical severity score, the security team assesses exploitability, business impact, exposure and available compensating controls to determine the appropriate response.

Scenario 3: The third-party risk:- A supplier connects to a critical business system. The company has already invested heavily in endpoint protection, yet the supplier's access remains poorly governed. Strengthening access controls and monitoring may reduce a more immediate business risk than purchasing another security product.

These examples illustrate why cybersecurity investment should follow risk—not vendor pressure, fear or technology trends.

The NIST Cybersecurity Framework 2.0 and NIST's enterprise risk-management guidance support a risk-based approach: identify what matters, assess potential business impact, prioritize responses and communicate risk in terms leadership can act upon.

Before approving a significant cybersecurity investment, I believe leaders should ask five questions:

What business risk are we addressing?

What evidence shows that the risk is significant?

Can existing controls or process improvements address it?

How will we measure the expected risk reduction?

Who owns the outcome, and when will we review it?

The objective is not to spend less on cybersecurity at any cost. Underinvestment can be just as dangerous as wasteful spending. The objective is to allocate resources where they deliver the greatest defensible reduction in risk.

For CISOs, this also means moving beyond technical justifications. Executives need to understand the business exposure, available options, trade-offs and consequences of delaying action.

My view: the strongest cybersecurity investment is not necessarily the newest or most expensive. It is the one that addresses a meaningful business risk and delivers a measurable improvement.

For fellow CISOs, CIOs and security leaders: How do you decide which cybersecurity investments deserve funding when the budget cannot cover everything?

I'd welcome your perspectives.
