What Our Linux Security Hardening Service Covers

Security Posture Review

Understand your risk position

We assess your current Linux environment, identifying misconfigurations, outdated packages, insecure protocols, and weak access controls.

Access & Identity Controls

Limit access, increase accountability

We review and enhance user permissions, SSH configurations, and authentication methods – enforcing the principle of least privilege across your systems.

Patching & Vulnerability Management

Stay protected against known threats

We ensure systems are up to date with security patches, and implement repeatable processes for identifying and remediating vulnerabilities.

Configuration Hardening

Best-practice Linux security, implemented

From disabling unused services to securing default settings and logging, we harden your systems in line with CIS benchmarks and industry best practice.

Firewall & Network Lockdown

Control what gets in and out

We audit firewall rules, restrict unnecessary ports and services, and help you build a secure network perimeter around your Linux estate.

Custom Hardening for Your Environment

Security that fits your setup

No two environments are the same. We tailor our hardening to suit your architecture, compliance needs, and operational demands.
