The CIS Critical Security Controls are a prioritised, prescriptive set of cybersecurity best practices developed by the Center for Internet Security. They’re designed to answer a simple question: if you can only do a few things, what should you do first?
The controls are organised into three Implementation Groups:
IG1 — essential cyber hygiene for smaller organisations with limited resources
IG2 — for organisations with more complexity and dedicated IT staff
IG3 — for organisations facing sophisticated threats or regulatory requirements
What makes CIS Controls practical is their focus on actions that actually stop attacks. They’re based on real-world threat data and updated regularly to reflect the current landscape. CyberNow helps you assess your environment against the controls and build a roadmap that’s right for your size and risk profile.
