Harden Your Infrastructure Against Real-World Threats
Default configurations are almost never secure. Misconfigured servers, open firewall rules, weak authentication, and unpatched systems are among the most common entry points for attackers. System hardening closes these doors — systematically reducing your attack surface.
Our system security service assesses your current infrastructure configuration, identifies specific hardening opportunities, and implements the controls needed to protect your systems against the threats your organisation actually faces — from ransomware and phishing to insider attacks.
Services tailored to your organisation
Server & Endpoint Hardening
CIS benchmark-aligned hardening of Windows, Linux servers, and endpoints — removing unnecessary services and locking down configurations.
Automated hardening scripts, Group Policy configuration, and before/after CIS-CAT benchmark scoring for auditability.
Access Control & MFA
Implement multi-factor authentication, privileged access management, and least-privilege access controls across your environment.
Covers Entra ID / Active Directory hardening, MFA rollout, Conditional Access policies, and privileged access workstation setup.
Security Monitoring & SIEM
Deploy centralised security event logging, alerting, and monitoring to detect threats before they cause significant damage.
Includes SIEM configuration, alert rule development, log retention policy, and integration with your incident response process.
Email & Phishing Protection
Harden your email environment with SPF, DKIM, DMARC, advanced threat protection, and anti-phishing controls.
Microsoft Defender for Office 365 or equivalent configuration, safe links, safe attachments, and user awareness simulation.
System Security Implementation
From current state assessment to hardened, monitored infrastructure
Security Assessment
Comprehensive review of your current security configuration against CIS benchmarks and Cyber Essentials requirements.
Hardening Implementation
Implement prioritised security controls — hardening configurations, deploying MFA, and tightening access controls.
Monitoring & Validation
Deploy monitoring infrastructure, validate all hardening changes, and document the improved security posture.
Measurable outcomes that drive real value
Dramatically Reduced Attack Surface
CIS benchmark hardening closes the configuration vulnerabilities that attackers consistently exploit for initial access.
Threats Detected Faster
Centralised logging and alerting means security incidents are detected in hours — not the industry average of months.
Cyber Essentials Ready
Our hardening work aligns with Cyber Essentials and Cyber Essentials Plus requirements — supporting government contract eligibility.
