Strengthen Your Foundation 

System hardening prevents misconfigurations and secures systems from day one, minimising early risk and building long-term resilience across your IT and OT environments. By strengthening your systems through trusted security standards, removing unnecessary components, and addressing vulnerabilities, we help you establish a hardened baseline that reduces downtime, audit findings, and operational risks.

Whether you’re managing legacy infrastructure or scaling in the cloud, our system hardening services cover the full technology stack.

What Benchmarks Do We Follow?

Our system hardening approach is rooted in compliance and global best practices: 

  • CIS Benchmarks: Detailed configuration standards that secure operating systems and applications by reducing vulnerabilities.
  • DISA STIGs: Security technical implementation guides that enforce strict controls in high-assurance environments.
  • ISO/NIST Mapping: International framework alignment providing guidelines for information security management and risk control. 
  • Vendor Best Practices: OEM-recommended controls from Microsoft, Red Hat, and other platform vendors to ensure secure and supported configurations.

 

Quadron System Hardening: What We Deliver 

 

  • Configuration Reviews: In-depth assessments to uncover misconfigurations and reduce the attack surface by eliminating insecure defaults and unnecessary components. 
  • Remediation Plans: Prioritised, actionable guidance tailored to reduce risks and aligned with compliance requirements.  
  • Optional Fixes: Hands-on support or automated solutions to accelerate remediation and strengthen protections.  
  • Documentation & Policy Support: Audit-ready hardening guidelines and policy documentation.
  • Knowledge Transfer Workshops: Practical sessions to upskill client teams and embed secure configuration practices.

We can support your team during audits, integrate with DevSecOps pipelines, or deploy custom CI/CD policies for continuous system hardening.
