Infrastructure HardeningClose the open doors before they are found

Hardening reduces your attack surface by fixing configurations, removing unnecessary services and enforcing strict controls. Where a pentest finds the weakness, hardening closes it for good.

Approach

Three Layers of Hardening

From the OS to the access layer, each layer is hardened separately.

OS & Servers

Applying CIS-based secure baselines, removing unused services, kernel hardening and patch management.

Network & Perimeter

Segmentation, firewall rule review, closing unnecessary ports and Zero Trust architecture design.

Identity & Access

Least-privilege enforcement, stale account removal, MFA enforcement and Active Directory hardening.

Our Process

01

Baseline Assessment

Reviewing current configuration against a standard baseline to find gaps.

02

Baseline Design

Designing a secure configuration tailored to your operational needs.

03

Implementation

Phased rollout with rollback plans and zero service disruption.

04

Validation Testing

Ensuring hardening has not broken any functionality.

05

Documentation

Delivering secure-configuration documents for maintenance and audits.

06

Compliance Monitoring

Periodic checks to detect configuration drift from the baseline.
