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.
CVE Triage Is Broken. Here's a Better Workflow.
Most enterprise CVE queues are noise. KEV plus EPSS plus reachability plus policy-as-code cuts the real actionable list to a manageable few percent.
How to Respond When a CVE Drops in a Package You Ship
A working playbook for the day a CVE lands in your dependency tree: confirm exposure with SBOM queries, judge real exploitability, patch or mitigate, then prove it and publish VEX.
KEV, EPSS, CVSS: Which Signal Should Drive Patching?
CVSS measures severity, EPSS predicts exploitation, KEV confirms active exploitation. Each answers a different question, and patching policy should use all three.
The End of CVSS-Only Prioritization
A single static severity score cannot tell you which vulnerability to fix first. Modern prioritization is a function of reachability, exploitability, and business context — and CVSS is only one input.
What is Risk Scoring
Vulnerability risk scoring ranks flaws by real exploitability and exposure, not just CVSS severity. Here's how it works and why it matters.
Security Vulnerability Remediation: Process, Prioritization, and SLAs
Finding vulnerabilities is the easy half. A working remediation program needs ownership, evidence-based prioritization, and SLAs that engineering teams can actually hit.
