Definition

What is system hardening?

System hardening is the process of securing a computer system by reducing its attack surface. Every program, service and default setting that is not required for operations represents a potential risk.

We go far beyond simple firewall rules. At INLYSE, hardening means deep optimization of the operating system, applications and network configuration according to the principle of least privilege.

Reduce Attack Surface

Drastically reduce the exposed attack surface through restrictive, controlled configurations.

Maintain Compliance

Support regulatory requirements such as ISO 27001, GDPR and BSI baseline protection.

Stop Lateral Movement

Hardened systems reduce the chances of lateral movement and privilege escalation.

Ransomware Protection

Limit ransomware propagation by closing common attack vectors and misconfigurations.

Our Approach

Your Path to a Hardened Environment

Our process is precise, measurable and designed to produce visible security improvements quickly.

01

Assessment and Scan

Initial audit against CIS Benchmarks with a clear picture of current control and compliance gaps.

02

Design

Tailored hardening profile designed to protect systems without disrupting business processes.

03

Hardening

Controlled rollout of the configurations with immediate reduction of exposed attack paths.

04

Validierung

Final verification, compliance evidence and complete documentation for your teams and auditors.

Deep Dive

Comprehensive protection on every layer

We do not just harden the surface. Our specialists work deep inside the architecture to make secure configuration the default state.
