What The Experts Are Saying

  • The CIS Controls® take the background and knowledge of cybersecurity experts literally around the world and help focus efforts on things that are of most value. Directly impacting the adversaries and challenges we face today on our networks.
    Harley Parkes
    Director, ACD (Integrated Adaptive Cyber Defense)
  • Without this resource, the hardening of our devices would have taken a lot longer and required many meetings between IT and Security to debate which configuration settings to change and the impact they could have. The CIS Benchmarks™ provided the necessary information to alleviate many of the fears IT may have had with changing specific settings.
    Adam
    Banking Information Security Engineer
  • We work with sensitive information on a daily basis. The CIS Controls® along with CIS-CAT® Pro, a proven and indispensable tool, helps us to evaluate and maintain a security baseline for our IT infrastructure.
    Sasawat Malaivongs
