Cybersecurity’s Hidden Flaw: Chasing Numbers Instead of Reducing Risk
After more than two decades of securing Fortune 500 environments, cybersecurity veteran Jason Fruge issues a stark warning: most cybersecurity teams are measuring the wrong things. Behind the dashboards, KPIs, and daily patch reports, there’s a dangerous illusion—one that can make an organization appear secure while leaving critical systems wide open.
In an era of increasing sophistication in cyber threats, Fruge argues that traditional vulnerability management metrics—like patch counts, scan coverage, and mean remediation times—have become vanity metrics. These metrics make security teams look busy but fail to deliver real insight into risk. The result? Misplaced confidence, wasted resources, and exposures that threat actors are only too ready to exploit.
Vanity Metrics: The Cost of Looking Secure
1. What Are Vanity Metrics?
These are numbers that look impressive in reports but don’t actually reflect improved security outcomes. They include:
– Volume metrics: How many patches were applied or vulnerabilities scanned.
– Time-based metrics: MTTD or MTTR, with no context of risk or impact.
– Coverage metrics: Like “95% scanned,” ignoring which 5% were missed.
2. The Problem with These Metrics
- Misallocated Effort: Teams spend energy fixing easy problems to check boxes.
- False Confidence: Leadership feels reassured by numbers that don’t reflect actual risk.
- Broken Prioritization: Without context, critical threats get buried in noise.
- Strategic Stagnation: Activity is rewarded over results, and innovation suffers.
3. Real-World Consequences
Breaches have occurred in environments that seemed well-secured on paper, highlighting that these traditional KPIs can be dangerously misleading if not tied to actual threat relevance.
Transitioning to Metrics That Matter
To truly reduce risk, organizations need to replace vanity metrics with meaningful security metrics that provide real-time, contextual insight:
- Risk Score Tied to Business Impact: Combines likelihood, exploitability, and asset value. Reflects actual risk, not just activity.
- Critical Asset Exposure Over Time: Focuses on how well the organization is protecting its crown jewels.
- Attack Path Mapping: Identifies how attackers could chain exposures to reach valuable targets.
- Exposure Class Breakdown: Shows what types of vulnerabilities dominate (e.g., identity, misconfigurations, etc.).
- MTTR for Critical Exposures Only: Targets high-risk vulnerabilities tied to real attack paths.
These metrics empower both technical and business leaders to speak a common language: risk. They help shift conversations from “How many patches did we apply?” to “Are we safer today than we were last quarter?”
Strategic Shift with CTEM
Fruge recommends frameworks like Continuous Threat Exposure Management (CTEM) to implement this transformation. CTEM allows organizations to move from static vulnerability lists to a dynamic model that continuously maps threats, prioritizes actions, and validates improvements. According to Gartner, by 2026, CTEM adopters could reduce breaches by up to two-thirds—a compelling case for rethinking what we measure.
What Undercode Say:
At Undercode, we’ve watched this debate evolve for years—and Fruge’s call for action hits the bullseye. Let’s break it down analytically:
1. Cybersecurity Metrics ≠ Security
The biggest flaw in current infosec operations is the confusion between measuring effort and measuring results. Just like DevOps had to evolve past deployment counts to actual system reliability (SRE), cybersecurity must evolve past patch counts to actual risk posture.
2. Vanity Metrics are Operational, Not Strategic
Metrics like MTTR and coverage are great for tracking the efficiency of security operations—but only if paired with risk relevance. A fast patch on a low-priority asset doesn’t move the needle on actual security.
3. Organizations Still Reward Motion Over Progress
Dashboards tend to favor upward trends. That’s dangerous. We’ve seen firms with 90% scan coverage still fall to ransomware because that missing 10% included high-privilege domain controllers.
- The Illusion of Control is a Risk Multiplier
Vanity metrics lull leadership into a false sense of security. This becomes a strategic liability when budgets are allocated based on “green” dashboards rather than actual threat exposure.
5. Real Metrics Demand Contextual Intelligence
Attack path analysis, business-critical asset mapping, and contextual risk scoring require deeper integration between vulnerability management, identity systems, and asset inventories. It’s harder—but also smarter.
6. MTTR Alone Is Dangerous
A low average MTTR can mean
7. CTEM Is the Future (But Needs Investment)
Undercode has covered CTEM extensively, and we see it as the future of modern cybersecurity programs. The shift from reactive patching to proactive exposure management is crucial—but tooling and cultural change are prerequisites.
8. Risk Reduction Is a Business Function
CISOs must increasingly speak the language of business. Framing metrics in terms of potential loss, financial exposure, and operational disruption helps bridge that gap and drives executive buy-in.
9. Boards Must Be Educated on Metric Maturity
One key role of security leaders is teaching boards the difference between activity and effectiveness. Without that, even the best metrics can be misunderstood—or weaponized.
10. What You Don’t Measure Can Hurt You
Just as important as selecting the right metrics is recognizing what you’re not measuring. Shadow IT, insider threats, and third-party risk often live outside current reporting—and that’s a blind spot threat actors love.
Fact Checker Results:
- True: Vanity metrics like patch count and scan volume are commonly misused in reporting.
- Supported: Gartner does predict CTEM will significantly reduce breach frequency by 2026.
- Valid: Attack path mapping and asset criticality are proven methods for contextual risk evaluation.
