Reinventing cyber budgeting: From legacy spend to quantified risk

Published on
May 27, 2026

Cyber risk is rising while budgets remain constrained.

That tension is now visible across most organisations. Investment in cyber has plateaued, yet the threat landscape continues to expand in frequency, sophistication, and impact. Despite this, many organisations continue to budget in the same way – rolling forward prior spend, adjusting incrementally, and reinforcing existing control environments.

This creates an inherited structure that reflects past decisions more than current exposure. A CISO we worked with described it simply: “We spend weeks building the numbers, then an hour deciding them. Nothing material changes.”

The model is under strain — and leaders are feeling it

Several structural pressures sit behind this.

Large organisations are now managing extensive portfolios of cyber vendors, often with overlapping capabilities across multiple areas such as identity, endpoint security, and network protection. Each control serves a purpose, but assessing them collectively and challenging their value vs the current risk picture is often a gap in the budgeting process.  

Budget cycles can involve months of preparation, yet executive discussions are often limited and too often the right expertise to discuss inevitable trade-offs isn’t in the room. In that environment, meaningful reallocation becomes difficult, and existing spend persists.

This creates two challenges for leadership teams:

  1. Lack of clarity: When every control appears essential, prioritisation becomes difficult and the link between investment and risk reduction remains unclear.
  2. Credibility: During periods of cost pressure, each function in an organisation is expected to respond and to “do their bit” but often the cyber capability feels it can’t, particularly when the implications of change cannot be clearly articulated. This can affect how cyber is perceived in wider business discussions.

External pressure is also increasing. Regulatory expectations are also changing, in particular boards are expected to be able to show evidence of the process behind decision making and are taking on more accountability.  Leaders are being asked to explain how cyber investment translates into reduced exposure, operational continuity, and preparedness. Where that link is unclear, scrutiny increases.

A more disciplined approach to investment

Some organisations are beginning to address this by making cyber investment decisions more explicit and outcome-led.

We believe cyber risk quantification (CRQ) can play a central role in that shift. Modelling realistic threat scenarios and understanding their most likely financial and operational impact delivers a clearer view of exposure. CRQ also provides visibility over the effect investment in different controls can have over that financial an operational impact.

One global manufacturer used this approach to review its identity environment. Over time, multiple tools had been deployed to address specific issues. When mapped against quantified risk scenarios, a smaller number of controls accounted for a disproportionate share of risk reduction. Others had limited impact relative to their cost.

The outcome was a reallocation of investment towards areas with the greatest effect on overall exposure.

This approach introduces greater discipline into decision-making. It allows leaders to understand where investment has the most material impact, support trade-offs with evidence, and demonstrate how spend aligns with risk. For leadership teams, the question centres on whether investment is clearly linked to the risks that matter most, and whether that link can be communicated with confidence to the board and external stakeholders.

Reinventing cyber budgeting: A wake up call for leaders

Cybersecurity has entered a new phase. Budgets are flattening while cyber risk accelerates. Yet most cyber budgeting still relies on rolling forward last year’s spend, adjusting at the margins, and defending what’s already in place. It feels safe, but it locks organisations into historic decisions that no longer reflect today’s risks. So, what do leaders need to do to stay ahead?

A risk-based approach to cyber budgets

Cybersecurity budgets are often poorly aligned with the actual level of risk to the organisation. Such misalignment can be driven by local challenges measuring and quantifying cyber risk, but it is compounded by the challenge of mapping perceived risk levels to security staff levels, controls, and approaches to risk mitigation. This article suggests a practical framework for leaders on how risk can become the driver of budgeting decisions.

Healthcare in the crosshairs: we’ve come a long way

Ransomware is now in healthcare’s “blast radius”, exposing underinvestment and rising risk. Cyber incidents now directly affect patient care - not just IT. The challenge is decision-making. Leaders struggle to quantify risk and prioritise spend. So how can they stay ahead?
