Security error budgets: gating risk instead of blocking everything
Google's SRE teams have spent an error budget on reliability since 2016 — applying the same model to security turns blanket blocking into risk-weighted gating.
Using EPSS scores for vulnerability remediation prioritization
EPSS predicts exploitation probability for every CVE on a 0-1 scale, updated daily. Paired with CVSS, it turns a 1,000-ticket backlog into a short, defensible list.
CVSS 4.0 vs. 3.1: what actually changed, and why your priority list should too
CVSS 4.0 killed the Scope metric, added Attack Requirements, and split scoring into CVSS-B/BT/BE/BTE labels — here's what that means for triage.
CVSS, EPSS, and KEV Explained: A Prioritization FAQ
CVSS measures severity, EPSS estimates exploitation likelihood, and CISA KEV lists what is actively exploited. Here is how the three differ and how to use them together.
Understanding CVSS Scores
CVSS turns a vulnerability's characteristics into a number from 0 to 10 and a severity label. Here is what the score actually measures, how the metrics combine, and why the number alone should never drive your patching.
Cost-Per-Verified-Finding: How Agentic AI Breaks Vulnerability Triage
Agentic AI can generate findings faster than any team can read them. The metric that survives that flood isn't cost-per-finding, it's cost-per-verified-finding. Here's why verification is now the bottleneck.
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.
Best Vulnerability Management Tools in 2026: An Honest Buyer's Guide
An honest guide to the best vulnerability management tools in 2026 — from broad asset scanners like Tenable, Qualys, and Rapid7 to cloud-native Wiz and reachability-driven SCA from Snyk and Endor Labs — with a clear 'best for' for each and where Safeguard fits.
The Economics of Vulnerability Backlogs
A vulnerability backlog is an inventory problem with interest payments. Triage costs, carrying costs, and why fixing by EPSS beats fixing by CVSS on pure ROI.
Understanding CVSS scoring for vulnerabilities
CVSS scores run 0-10, but a 9.8 doesn't always mean patch tonight. Here's how base scores are calculated and why context beats the number.
CVSS scoring explained, and where severity scores go wrong
CVSS score explained through a real case where CVSS, EPSS, and KEV disagreed, showing why severity alone misleads prioritization decisions.
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.
