What patch compliance rate should organizations target?

Industry benchmark: 95%+ of critical patches applied within 24 hours, 99%+ within 7 days. PCI DSS requires critical patches within 30 days. HIPAA: within 60 days. Zero-day patches: emergency change within 4 hours for internet-facing systems.

How do you automate patch compliance at scale?

Use automated patch management: AWS Systems Manager Patch Manager, Red Hat Satellite, or Ansible. Define maintenance windows per tier (dev: weekly, staging: bi-weekly, prod: monthly). Automate compliance reporting against CIS benchmarks and track MTTP per severity tier.

How It Works

Calculate patch compliance rate across your server fleet. Measure mean time to patch critical CVEs and exposure window against active exploitation

Each component has a specific meaning:

Server fleet — The server fleet recorded for the patient or scenario being assessed.

Note: Interpret the patch compliance result against the clinical thresholds and context described above.

How to Use

Enter the server fleet for the patient or scenario you are assessing. Calculate patch compliance rate across your server fleet. Measure mean time to patch critical CVEs and exposure window against active exploitation. Use the patch compliance result to inform your clinical assessment.
