CIS Critical Security Controls v8.1 Poster
Published on March 4, 2026
The CIS Critical Security Controls® (CIS Controls®) are a prioritized and prescriptive set of cybersecurity best practices that help organizations defend against the most common and impactful cyber threats. They are used by thousands of security practitioners worldwide to strengthen and maintain their cybersecurity posture.
Developed in partnership with the SANS Institute, the CIS Controls v8.1 Poster provides a clear, visual overview of how organizations can use the CIS Controls to build and sustain effective cyber defense. It highlights all 18 Controls and outlines the supporting tools and resources from CIS that guide implementation, measurement, and continuous improvement. The poster also shows how the CIS Controls help organizations build stronger defenses and maintain informed, resilient operations.
