Endpoint hardening using CIS Benchmarks for UK SMEs

This article offers practical guidance for UK SMEs on applying CIS Benchmarks to endpoint hardening: selecting appropriate baselines for Windows, macOS and Linux; limiting local admin rights; enforcing patching and application controls; tightening browser, scripting and macro settings; enabling disk encryption, secure boot and endpoint protection; validating configurations and monitoring for drift; and rolling out changes via pilots and documented exceptions. It emphasises balancing security with usability and maintaining a repeatable, monitored baseline rather than treating hardening as a one-time project.
