Windows Server CIS Benchmark Assessment & Remediation
Assess Windows Server configuration against the applicable CIS Benchmark, with compatibility review, documented exceptions and controlled remediation.
Secure configuration of Windows Server requires more than applying a hardening template.
Security settings must be evaluated against server roles, application dependencies, operational requirements and the risk of disrupting production workloads.
This assessment evaluates Windows Server security configuration against the applicable CIS Benchmark, identifies gaps and develops a controlled remediation path.

Example public finding

WSCIS-031 — Security baseline control is not consistently enforced across member servers
Observation
A security configuration expected for the selected server baseline is applied inconsistently across the assessed server estate.
Some systems receive the intended setting through Group Policy while others retain local or legacy configuration.
Why it matters
Inconsistent configuration creates different security behavior between servers performing similar roles and makes future security validation more difficult.
It can also cause newly deployed or rebuilt systems to return to an unintended configuration state.
Recommended direction
Determine the intended baseline, identify the authoritative configuration source, evaluate compatibility requirements, and enforce the approved configuration through centrally managed policy.
Systems requiring exceptions should be explicitly documented rather than left in an unmanaged state.
Remediation approach
Remediation is not performed by blindly applying every available benchmark setting.
Each failed control is classified as:
- Remediate
- Investigate
- Exception required
- Not applicable
- Dependency prevents immediate remediation
Changes may then be delivered through:
- Group Policy
- Local security configuration
- PowerShell
- Endpoint or configuration-management platforms
- Server rebuild or modernization
- Application remediation
Production-impacting controls should be tested before broad deployment.
