Security posture thinking

Practitioner writing on CVE prioritization, CVSS contextualization, CISA KEV correlation, remediation SLA enforcement, and attack surface scoring — from engineers who ran these workflows manually before building Vendrsec to automate them.

The Vulnerability Noise Problem: Why Your Scanner Is Not Broken

Security teams treat high finding volume as a scanner accuracy problem. It isn't. Here's why prioritization, not detection, is the unsolved challenge.

CVSS 3.1 Scores Were Never Designed to Set Remediation Priority

CVSS measures exploitability and impact in isolation from your environment. Understanding what the score actually tells you — and what it deliberately leaves out.

Building an Asset Criticality Model That Reflects Business Risk

How to go from a flat asset inventory to a weighted criticality map that tells your scanner's findings where they actually matter.

Network Reachability Analysis: The Missing Variable in Vulnerability Prioritization

A CVSS 9.8 on an air-gapped dev server is not the same risk as a CVSS 7.2 on your public API gateway. Building the reachability graph that makes this systematic.

CISA KEV, NVD, and Threat Intel Feeds: What to Trust for Exploit Prioritization

Not all exploit intelligence sources are equal in timeliness, coverage, or signal-to-noise ratio. A practical guide to which feeds matter.

Alert Fatigue in Vulnerability Management Is a Prioritization Failure

When every finding is labeled Critical, nothing is. How tool over-alerting creates the conditions for the findings that matter to slip through.

What a Good Remediation Ticket Actually Contains

Most security tools hand engineers a CVE ID and a link to NVD. We looked at what information actually gets a ticket closed quickly.

CISOs and Engineers Speak Different Risk Languages. Here's the Translation Layer.

CISOs want exposure reduction in business terms. Engineers want specific fix instructions. The gap between these audiences is where programs stall.

EPSS vs CVSS for Vulnerability Prioritization: Using Both Without Double-Counting
