From Risk Manager to Business Enabler: How CTEM Transforms the CISO Role

Conor Heslin

CISOs face growing pressure to explain organizational risk, but traditional vulnerability management can’t keep pace with fast-moving threats or fragmented data. Continuous Threat Exposure Management (CTEM) offers a business-aligned approach that continuously identifies, validates, and prioritizes the exposures that matter most. Nagomi makes CTEM executable by unifying security data, mapping exposures to business impact, and showing clear, validated progress that boards can understand, shifting security from reactive firefighting to measurable risk reduction and strategic influence.

It’s Monday morning. The board asks: “How exposed are we to the recent scattered spider attack?” You have 73 dashboards, 22 security tools, and thousands of vulnerabilities, but no single answer. You know you’re protected in some areas. You suspect you’re exposed to others. But you can’t prove either.

Every breach puts the business at risk and the CISO in the spotlight. The 2025 Nagomi CISO Pressure Index shows how real that pressure has become:

  • Eighty percent of CISOs report high or extreme stress, 
  • Two-thirds say they feel burned out weekly or even daily. 
  • Nearly half admit that stress is already affecting their ability to prepare for incidents.

That pressure is also shifting in origin:

  • Forty-four percent of CISOs now say board and executive demands are their top source of stress, a larger driver than the threats themselves. 
  • While most CISOs feel confident they can quantify risk, more than half say they lack metrics that make sense to leadership. 
  • Many oversee more than 20 tools that fail to deliver a unified, business-level view of exposure.

And the stakes are rising. CISOs who can’t answer board questions with confidence are increasingly being replaced, or worse, held personally liable when breaches occur. The window to get ahead of exposure is closing. In 2024, the average time from vulnerability disclosure to active exploitation dropped to just 5 days, while most organizations take 30+ days to patch.
This gap between security data and business clarity is growing. Boards ask, “How exposed are we?” while CISOs lack the tools to translate fragmented data into complete answers. At the same time, attackers are moving faster with the help of agentic AI and automation, exploiting weaknesses before teams can react.

Here’s the inflection point: Either CISOs evolve how they measure and communicate risk, or they’ll continue fighting a losing battle with tools that can’t keep pace and boards that won’t wait.For many leaders, this cycle feels unsustainable. But it also creates a turning point where CISOs can move from reacting to incidents toward managing exposure as a measurable business outcome.

Why Traditional Vulnerability Management Can’t Keep Up


Traditional vulnerability management is reactive, tool-siloed, and incident-focused. Continuous Threat Exposure Management  (CTEM)  is continuous, business-aligned, and exposure-focused. It’s not an incremental improvement, it’s a fundamental shift in how security operates.

CTEM introduces a new way of working. Instead of periodic audits and reactive patching, it focuses on continuous assessment and improvement; a system infinitely more capable of answering board questions around exposure.

Gartner defines CTEM as a five-step cycle: scoping, discovery, prioritization, validation, and mobilization. The aim is to continuously evaluate and reduce threat exposure across all digital assets. CTEM does not rely on adding more tools; it connects the ones already in use to generate practical insights which can translate a noisy security stack into something business-aligned and digestible.

Leading organizations are already making the shift. Gartner predicts that by 2026, organizations prioritizing CTEM will be three times more likely to reduce breach impact. Those still running traditional vulnerability management will find themselves outpaced, by both attackers and competitors.

How CTEM Works:

  • Scoping aligns security with business-critical systems and priorities. → No more defending every asset equally. Focus protection where business impact is highest.
  • Discovery consolidates asset and control data into a single, accurate view. → One source of truth means no more conflicting reports to the board.
  • Prioritization identifies which exposures matter most based on attacker behavior and existing defenses. → Stop chasing noise. Address exposures attackers will actually exploit.
  • Validation ensures controls work as intended through continuous testing. → Prove your controls work before an incident proves they don’t.
  • Mobilization drives coordinated remediation with clear accountability and measurable progress. → Turn security from a cost center into a measurable performance function.

CTEM gives CISOs a way to show progress through evidence and results rather than impenetrable metrics or siloed dashboards.

CTEM: From Concept to Competitive Advantage

Your competitors are already moving. Organizations with mature CTEM programs are reducing breach likelihood by 50%, cutting mean time to remediation by 60%, and gaining board confidence that translates to budget approval and strategic influence. The gap between leaders and laggards is widening fast.

But here’s the challenge: many organizations align to CTEM in theory but struggle to put it into practice. Visibility is now the cost of entry. Execution is what differentiates a security team in 2025.

How Nagomi Turns CTEM into Action

Nagomi Control, powered by Exposure Lens, builds the execution layer that makes CTEM work day to day. It consolidates data from across your security stack, connecting assets, controls, vulnerabilities, and threats, to show and prioritize risk in full business context. Misconfigurations, missing controls, and excessive privileges are treated as high-priority exposures so teams can focus on what truly reduces business risk.

By continuously mapping exposures to live threats and control effectiveness, Nagomi answers the questions boards care about most:

  • Which exposures pose the greatest business risk?
  • Which controls are failing?
  • How quickly are we closing the gaps, and what progress can we prove?
  • Which exposures pose the greatest business risk?
  • Which controls are failing?
  • How quickly are we closing the gaps, and what progress can we prove?

The impact is tangible. Instead of reporting on the number of vulnerabilities fixed, security leaders can show that validated exposure across critical revenue systems has fallen by 40 percent. This reframes cybersecurity as a driver of business resilience and turns board discussions from reactive updates into conversations around continuous improvement.

Nagomi also extends accountability beyond the SOC. By connecting exposure data, control health, and threat intelligence in a unified platform, it ties remediation tasks to the right business owners and ensures collaboration across IT, operations, and governance teams. The result: shared responsibility for reducing exposure and measurable evidence of improvement.

From Pressure to Progress

CTEM won’t remove the pressures facing CISOs, but it transforms that pressure into measurable progress. Through continuous evaluation, contextual prioritization, and cross-team collaboration, security leaders can show exactly how risk is being reduced and where investment is paying off, turning security from a cost center into a business performance function.

turning security from a cost center into a business performance function.

The question isn’t whether CTEM will become the standard, it already is. The question is whether you’ll lead the shift or be left defending an outdated approach to a board that’s run out of patience.

Start measuring what matters. Turn exposure into a business outcome. Make CTEM executable.
