About this tool
Vulnerability SLA Compliance Calculator
The Vulnerability SLA Compliance Calculator computes on-time remediation rate by severity tier with remediation velocity and MTTR trend.
• Calculate vulnerability SLA compliance for a security metrics dashboard
• Identify which severity tier has the worst compliance for remediation focus
• Track SLA compliance improvement after a vulnerability management initiative
• Report vulnerability remediation compliance to a compliance auditor

FAQ
What does this tool tell you?
The Vulnerability SLA Compliance Calculator computes on-time remediation rate by severity tier with remediation velocity and MTTR trend.
What affects the result most?
SLA compliance = vulns_patched_within_SLA / total_vulns × 100, computed per severity tier and combined for overall. Critical SLA 24–72 hrs: internet-facing systems or CISA KEV-listed. High SLA 7 days: standard production. Medium SLA 30 days: internal systems with limited exploitability. Target thresholds: ≥95% Strong, ≥80% Needs improvement, <80% Below target. Common industry benchmark for mature programs; calibrate to your regulatory or contractual baseline.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
