Latest Cybersecurity Blog Posts from Root Evidence

Explore how subrogation lawsuits are reshaping cyber insurance into a powerful force for accountability, turning security marketing claims into measurable, outcome-driven proof. This blog explains why insurers may become the industry’s most effective regulators and what that means for underwriting, vendor risk, and security investment decisions.

Companies are overwhelmed by vulnerabilities, yet still qualify for cyber insurance. This blog explores what actuarial data reveals about which vulnerabilities actually lead to financial loss and why most don’t matter as much as we think.

Evidence has launched the enterprise preview of Evidence Scan, a scalable vulnerability scanner designed to identify the risks that truly matter. Learn how it helps security teams cut through vulnerability noise and focus on the issues most likely to cause real-world financial loss.

We’ve spent years refining the math of loss. Now, we’re making that same "Loss-First" intelligence available directly to security teams. We are officially launching the Enterprise Preview for Evidence Scan: the first tool designed to let you see exactly which of your vulnerabilities could lead to breaches or real-world financial loss.

Cyber insurance is won or lost in the gap between CVSS “severity” and real-world financial exposure. This post explains why pricing and remediation should be driven by empirically exploited loss drivers, not theoretical scores, and how that shift sharpens underwriting and portfolio performance.

Organizations are reporting tens or even hundreds of millions of vulnerabilities, yet few appear to translate into real-world attacks or losses. This piece explores that contradiction and asks an uncomfortable question: if these flaws rarely change outcomes, why are vulnerability counts still used to define risk?

Not all threat intelligence feeds are created equal. This post explains why high-fidelity data built on direct observation of real compromises delivers clearer, more actionable security insight than rule-based feeds full of noise.

A sharp examination of the opposing incentives between vulnerability management vendors and cyber insurers reveals why counting vulnerabilities is a poor proxy for real risk. By reframing evidence around actual loss instead of noise, this piece argues for a more honest way to measure what truly changes security outcomes.

A compelling analogy between dark energy and orphaned, internet-facing systems reveals how forgotten assets quietly expand enterprise attack surfaces. It shows why unmanaged infrastructure becomes an invisible but powerful breach vector, and why exposing and eliminating these hidden systems is critical to preventing real-world compromises.

Cybersecurity is broken less by attackers than by the incentives shaping our tools, teams, and decisions. This post breaks down why risk based security is mostly a myth, how volume and fear replaced insight, and what it will take to realign the industry around outcomes that actually reduce loss.

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.
