Latest Cybersecurity Blog Posts from Root Evidence

We are drowning in confident conclusions built on shaky assumptions. This post shows how applying first principles thinking cuts through bad data, false causation, and noisy vulnerability scores to focus security decisions on what actually leads to real breaches.

This blog challenges the belief that patch management alone reduces risk, arguing that blindly fixing millions of vulnerabilities without adversary context often wastes time and resources. It makes the case for prioritizing patches based on how attackers actually operate, not on raw vulnerability counts.

Infosec is still playing the wrong game, trusting expert intuition, CVSS scores, and tradition instead of outcomes that actually prevent loss. This post argues for an Infosec Moneyball approach that replaces security theater with rigorous, dollar-driven decisions focused on what truly reduces breach and business impact.

This blog uses a surprising deck of cards analogy to expose a critical misunderstanding in cybersecurity: why CVSS scores measure severity, not risk. Learn how separating impact from likelihood leads to smarter vulnerability prioritization and better business aligned security decisions.

Are your vulnerability management and external attack surface programs actually working, or just reporting success? This post challenges conventional security metrics and argues that only warranties and real accountability can prove whether risk is truly being found, prioritized, and reduced.

Evidence’s first year charts its evolution from an idea into a movement, redefining vulnerability management through evidence-based prioritization, community collaboration, and real-world results. Read how practitioner insight, design partners, and a focus on measurable risk shaped the product and what comes next.

Read about why CVSS 4.0 struggles to gain real adoption, how its added complexity can reduce practical scoring resolution, and why base scores continue to undermine meaningful risk prioritization. This post breaks down the technical, philosophical, and incentive-driven reasons CVSS V4 has not fixed the problems it set out to solve.

Read why traditional EASM approaches fail to deliver a reliable picture of what organizations actually expose to the internet and why accurate, real-time asset inventory is becoming a prerequisite for both security and cyber insurance decisions.

Read about how cyber insurance carriers actually evaluate risk, losses, and security controls, and why many long-held infosec assumptions don’t match actuarial reality. This post breaks down how insurers really think about premiums, breaches, and which controls truly reduce financial loss.

A practical guide to using ROSI math to prioritize vulnerabilities based on real financial impact, not guesswork or compliance-driven patching.

A look at how history, and cybersecurity, keep proving that rational assumptions can still be wrong, and why the future of vulnerability management depends on evidence, not theory.

Rapid scanning and shared intelligence can shrink attacker dwell time, disrupt post-compromise movement, and meaningfully reduce breach impact.

Discover why AI is set to dramatically increase CVE volume and how this shift will force security teams to rethink prioritization, triage, and long-term risk strategy.

Security theatre gives organizations the illusion of safety. Shifting to true visibility and context-driven prioritization is what actually reduces real-world risk.

Cyber insurance is reshaping security. Vendors must deliver real efficacy and lower unit costs as market forces finally enforce accountability.

Trace the evolution of vulnerability management from early scanners to evidence-based security. Learn how forensics and actuarial data are redefining prioritization and shaping the next generation of risk reduction.

Explore why most vulnerability management efforts waste time and resources on low-impact flaws, and how a rational, evidence-based approach focused on real-world exploitation can redefine what “effective security” really means.

CVSS Base Scores were never meant to measure real risk. This post explains how their misuse distorts prioritization and why context (not convenience) must define vulnerability management.

Expose why CVSS misleads: inconsistent math, context-free scores, poor correlation to real exploitation and loss, and version/data flaws. Then, replace it with evidence-based, loss-driven prioritization and ROSI-focused metrics.

The Epoch Theory of Cybersecurity explains how attackers and defenders evolve through distinct eras, from manual exploits to scalable automation and, soon, AI-driven complexity. By understanding these epochs, organizations can anticipate shifts in attacker behavior, invest strategically, and force adversaries to spend more time and money, turning defense into an economic advantage.

Explore the coming “post-VM warranty world,” where vulnerability management shifts from empty promises to accountability. As vendors begin offering warranties, only those that back limited, high-impact vulnerabilities with real financial risk will align with customer success.

Expose the illusion of “fixing everything.” VM programs measure success by volume (tickets closed, vulns patched) but those metrics don’t reduce risk. True ROI comes from prioritizing exploited vulnerabilities and measuring avoided loss, not activity for activity’s sake.

Discover the concept of “nulns”: non-exploitable vulnerabilities often mistaken as risks. Learn why most security flaws may never lead to real-world breaches.

Vulnerability management is broken. 100+ security pros reveal why CVEs, bad tooling, and poor risk context are overwhelming teams.

Learn about “Stoplight Infosec”: color-coded scoring systems that masquerade as math but mislead security priorities. Replace arbitrary grades with better metrics that quantify real risk and ROI.

Master evidence-based vulnerability prioritization with the Triangle model. Focus on exploitability, adversary activity, and losses to reduce breaches effectively.

Understand the difference between vulnerability exploitation and actual financial loss in cybersecurity. Discover why not all exploits lead to breaches and how to focus on real risks.

Does prioritizing EPSS make sense in vulnerability management? Analyze the debate, FIRST guidance, and best practices for effective risk prioritization. Read the full analysis.

Find the remediation cut-off in vulnerability management. Compare models and cyber-insurance insights for defining when to stop patching.

Why zero-days are irrelevant in vulnerability management discussions. Focus on known CVEs for enterprise risk & separate myths from effective strategies.

Post-breach, how will you justify your vulnerability prioritization strategy? Learn defensible approaches using KEVs, compliance, and risk assessment to explain decisions to stakeholders.

Discover the missing KPI in vulnerability management: Forcing adversaries to innovate. Analyze data showing only 1.3% of CVEs are exploited and how to shift attack economics.

Uncover paradoxes in vulnerability management: Does fixing flaws always reduce risk? Explore scenarios, costs, and alternatives for smarter remediation strategies.

Debunk the myth of objective security scoring like CVSS and EPSS. Learn why subjectivity persists and how to validate models with real-world breach data.

Explore why financially motivated hackers rarely innovate, reusing known vulnerabilities for efficiency. Data from VulnCheck and reports reveal only 1.1% of CVEs are exploited. Learn more.

Embrace security optimism: Focus on evidence-based fixes for known vulnerabilities. Raise attack costs and protect against breaches with actionable strategies.
