What is CIS-CAT Pro Assessor?

CIS-CAT Pro Assessor is a specialized configuration assessment tool developed by the Center for Internet Security (CIS). Its core purpose is to provide cybersecurity professionals, auditors, and system administrators with an automated method to evaluate the security settings of operating systems, software applications, and network devices against the globally recognized CIS Benchmarks. These benchmarks are consensus-based, best-practice security configuration guidelines. Instead of manually checking hundreds of settings, CIS-CAT Pro scans your environment, compares configurations to the benchmark recommendations, and produces detailed reports highlighting compliance gaps and specific remediation steps. It's the bridge between theoretical security guidelines and practical, enforceable system hardening.

Key Features of CIS-CAT Pro Assessor

Automated CIS Benchmark Assessment

The tool automatically scans target systems and applications, checking their configuration against the latest CIS Benchmark recommendations. This eliminates human error and saves countless hours compared to manual audits, ensuring consistent and thorough evaluations every time.

Detailed Compliance Reporting

Generate comprehensive, easy-to-understand reports that detail pass/fail status for each benchmark recommendation. Reports include severity levels, technical details of non-compliant settings, and specific instructions for remediation, making them invaluable for both technical teams and management.

Support for Diverse Technologies

CIS-CAT Pro Assessor supports a wide range of platforms including Windows Server, Windows 10/11, major Linux distributions (RHEL, Ubuntu, SUSE), databases, cloud environments (AWS, Azure, GCP foundational benchmarks), and network devices, providing a unified assessment tool for heterogeneous environments.

Content Update Subscription

With a subscription, users receive continuous updates to the assessment content as new CIS Benchmarks are published and existing ones are revised. This ensures your assessments always reflect the most current security guidance and threat landscape.

Who Should Use CIS-CAT Pro Assessor?

CIS-CAT Pro Assessor is essential for any professional or organization responsible for system security and compliance. Primary users include Cybersecurity Analysts and Engineers who need to proactively harden systems; IT Auditors and Compliance Officers who must provide evidence for frameworks like NIST, ISO 27001, or PCI DSS; System and Network Administrators tasked with maintaining secure configurations; and Managed Security Service Providers (MSSPs) who deliver configuration assessment as a service to clients. It's particularly valuable in regulated industries like finance, healthcare, and government.
