Server Hardening
Systematic reduction of attack surface on your Linux and Windows servers, removing unnecessary services, tightening configuration and applying benchmarks so servers are harder to compromise.
Overview
Why it matters
for your business.
Default server installations prioritise convenience: unused services run, root login over SSH is allowed, old protocols remain enabled and logs are minimal. Every extra open door is an opportunity for attackers. Hardening closes them deliberately. We assess your servers against CIS Benchmarks for your operating system and agree a baseline suited to each server’s role.
Changes are applied carefully to avoid breaking applications: disabling unnecessary services and ports, enforcing key-based SSH, configuring host firewalls, tightening file permissions, enabling audit logging, setting up automatic security updates and endpoint protection. We script the baseline with Ansible or similar tools, so new servers are hardened consistently from day one.
What's included
- Server inventory and CIS Benchmark assessment
- Role-based hardening baseline for each server type
- SSH, firewall and service lockdown
- Patch management and update configuration
- Audit logging and integrity monitoring setup
- Automated hardening scripts for new servers
Outcomes
What changes
for your business.
Ideal for
- Businesses hosting applications on VPS servers
- On-premises Windows Server environments
- Teams preparing infrastructure for security audits
Reduced attack surface
Unneeded services and open ports are removed, leaving fewer ways for attackers to get in.
Consistent configuration
Scripted baselines keep servers uniformly configured instead of drifting apart over time.
Better forensic visibility
Audit logging records important events, helping investigations if something does go wrong.

FAQ
Common
questions.
Something else on your mind? Ask us directly.
Could hardening break our applications?
It can if done carelessly, which is why we test changes in staging first, apply them in stages and keep rollback steps ready. We document application dependencies before disabling services and schedule production changes in agreed maintenance windows.
How do we keep servers hardened after you finish?
Configuration drifts as people make changes. We provide scripts that can be re-run to reapply the baseline, plus compliance scans with tools like Lynis or OpenSCAP that report deviations, so your team can detect and correct drift regularly.
