CIS offers a variety of audit tools for assessing compliance with CIS Benchmarks.
CIS offers its members the CIS Configuration Audit Tool (CIS-CAT)—A Java-based tool that compares the configuration of target IT systems to CIS Benchmarks and reports conformance scores on a scale of 0-100. CIS-CAT is a SCAP-validated FDCC Scanner.
CIS-CAT gives IT and security professionals a fast, detailed assessment of target systems' conformance to CIS Benchmarks. By discovering any lack of conformance to CIS Benchmarks, CIS-CAT offers enterprises a powerful tool for analyzing and monitoring the security status of information systems and the effectiveness of internal security processes.

Using CIS-CAT, CIS Members can:

CIS-CAT is a host-based configuration assessment and audit tool. It includes both a command-line interface (CLI) and a graphical user interface (GUI). To support the broadest possible portability, CIS-CAT is a Java application and requires JRE v1.5 or later.
CIS-CAT and its JRE can reside on a target system or on any network drive or removable drive that has network access to the target system being assessed.
CIS-CAT currently supports the following Benchmarks:
CIS-CAT can read customized input files to allow members to compare the configuration of their systems with both the CIS Benchmarks and their customized configuration policies. This feature is enabled by user modification of the Benchmark XCCDF files.
CIS-CAT has been awarded NIST Security Content Automation Protocol (SCAP) Validation as a Federal Desktop Core Configuration (FDCC) Scanner. It supports the following content distributed from the NIST FDCC Repository:
