Security Hardening

Security Hardening: make your environment demonstrably safer

A penetration test reveals vulnerabilities. Hardening fixes them. ZETA assesses and strengthens your systems based on CIS Benchmarks, from Windows servers to Microsoft 365 and Azure.

What do we harden for you?

From operating systems to cloud platforms, based on CIS and Microsoft Secure Score

CIS Benchmark assessment

Measurement of your current configuration against CIS Level 1 and Level 2 standards. A clear score per system with prioritization of vulnerabilities.

Microsoft 365 Hardening

Email, SharePoint, Teams and Entra ID configured according to Microsoft Secure Score and the CIS M365 Benchmark. Phishing-resistant MFA, secure sharing permissions and mail flow protection.

Azure Security Baseline

Storage accounts, virtual machines, networks and identity settings configured in line with the Azure Security Benchmark and CIS Azure Foundations.

Windows & Linux Hardening

OS configuration, disabling unnecessary services, minimizing permissions, securing remote access and setting up audit logging. For servers and workstations alike.

Firewall & network review

Review of firewall rules for redundant access, open ports and legacy rules. Including recommendations for segmentation and least-privilege access.

Reporting & roadmap

An audit-ready document with findings, risk classification, priorities and an implementation roadmap. Usable for NIS2 evidence, ISO 27001 and your cyber insurer.

Our approach

Structured, from baseline measurement to a demonstrably secure configuration

1

Baseline measurement

Automated CIS Benchmark scan of your systems. The result: a score per component and a list of deviations from the standard.

2

Prioritization

Together with you, we determine which findings pose the greatest risk and should be addressed first, without unnecessary disruption.

3

Implementation

We implement the hardening measures in your environment, or guide your own IT team through the execution.

4

Reporting

A final report with a before/after comparison, residual risks and recommendations, usable as evidence for NIS2, ISO 27001 or your insurer.

Do you know how your systems score on the CIS Benchmark?

Most organizations have dozens of open vulnerabilities in their base configuration. ZETA maps them out and fixes them, demonstrably and documented.

  • Windows, Linux, M365 and Azure
  • Based on the CIS Benchmark & NIST
  • NIS2 and ISO 27001 reporting
  • Implementation by ZETA or guidance for your own IT
