What is a Build Review?
A Build Review is a detailed assessment of how securely your operating systems, servers, and desktop environments are configured before and after deployment. It evaluates security baselines, patch levels, access controls, and configuration policies against recognised best-practice frameworks.
For executives and IT leaders, this service provides assurance that your organisation’s foundational systems are resilient from day one. Poorly configured builds often serve as entry points for attackers — introducing unnecessary risk and non-compliance with standards such as ISO 27001, CIS Benchmarks, NIST CSF, and DORA.
Why Your Business Needs a Build Review
Even the most advanced security controls can fail if the underlying systems are insecure. Weak configurations, unnecessary services, and default credentials can all lead to breaches, ransomware, or compliance failures.
A Build Review ensures your operating systems — whether Windows, Linux, or macOS — meet security expectations before being rolled out to production. For regulated sectors, it provides documented evidence of due diligence and strengthens audit readiness.
Benefits of a Build Review
- Validate server and desktop configurations against CIS and NIST benchmarks
- Detect misconfigurations, insecure services, and unpatched components
- Demonstrate compliance with ISO 27001, NIST CSF, and DORA
- Reduce the likelihood of privilege escalation and malware infection
- Improve operational efficiency through standardised, hardened builds
- Strengthen governance and investor confidence in IT resilience
How Rexon Cyber Delivers
Rexon Cyber’s consultants perform a comprehensive review of system images, build templates, and configuration baselines. Using both automated assessment tools and manual verification, we benchmark against recognised frameworks such as CIS Level 1/2 and Microsoft Security Baselines.
We evaluate:
- User and privilege management
- Patch and update processes
- Logging and auditing configurations
- Service and process hardening
- Encryption and endpoint protection policies
Each engagement concludes with a technical findings report, an executive summary highlighting business impact, and a remediation roadmap prioritised by risk severity.
