How Risk Scoring Models Differ Across AppSec Platforms
CVSS, EPSS, SSVC, and vendor priority scores all measure vulnerability risk differently. Here's how they diverge, with real numbers, and how reachability analysis cuts through the noise.
EPSS Meaning: The Exploit Prediction Scoring System Explained
EPSS is a daily-updated probability that a given CVE will be exploited in the next 30 days. Here is what the score means and how to use it.
What Is a Risk Score in Vulnerability Management?
A risk score turns raw severity into a prioritized number by factoring in exploitability, exposure, and business context. Here is how to read and build one.
CVE scoring inconsistencies across vulnerability databases
Why the same CVE can carry three different severity scores across NVD, GitHub, and vendor advisories — and how to prioritize anyway.
Vulnerability Prioritization in 2025: EPSS, VEX, and the End of CVSS-Only Triage
CVSS scores alone cannot tell you what to patch first. EPSS exploit prediction and VEX documents are reshaping how mature security teams prioritize vulnerabilities at scale.
Vulnerability prioritization: moving beyond CVSS scores
CVSS scores flood teams with thousands of "Critical" findings, but fewer than 5% of CVEs are ever exploited. Here's how reachability and exploit data fix triage.
Risk-based vulnerability management explained
Why CVSS severity alone fails to prioritize vulnerabilities, how Trivy's default scoring falls short, and how EPSS, CISA KEV, and reachability data cut remediation backlogs by 95%+.
Reachability Analysis vs EPSS vs CVSS: Prioritization Showdown
CVSS scores severity, EPSS predicts exploitation, reachability proves applicability. A spec-level comparison of the three signals — and the order to apply them.
What is EPSS (Exploit Prediction Scoring System)
EPSS scores every CVE's real-world exploit probability. Here's how the FIRST.org model works, how it differs from CVSS, and how to use it to triage faster.
What is an Exploit
An exploit is code that weaponizes a vulnerability. Learn how exploits differ from CVEs, how attackers acquire them, and how to prioritize real exploitation risk.
CVSS vs EPSS vs KEV: A 2026 Prioritization Guide
How CVSS, EPSS, and CISA KEV combine into a defensible vulnerability prioritization model for 2026, with concrete thresholds and operational guidance.
How to Prioritize a 10,000-Finding Vulnerability Backlog
A five-digit backlog is not a ranking problem, it is a filtering problem. Here is the funnel that turns 10,000 findings into a few hundred that deserve engineering time.
