Infrastructure Security

Organizations whose IT infrastructure grew over time without a coherent security architecture — no segmentation, an Active Directory that was never hardened, or backups that were never actually tested.

Last updated — August 22, 2026

The problem this solves

A compromised workstation spreads across the entire information system for lack of segmentation, and the backups meant to enable recovery have often never been tested through an actual restore — the day they're needed is not the time to find out.

What's included

Network segmentation and VLAN implementation

Active Directory and group policy hardening

Privileged access management

Backup security and restore testing

Logging architecture

System hardening per CIS Benchmarks

Frameworks applied

Knowledge transfer to internal teams

6 to 12 weeks depending on the size of the environment and the number of migration phases

Typical duration

Client prerequisites

  • Administrator access to the relevant systems during the engagement phases
  • Availability of a maintenance window for structural changes
  • Designation of the internal teams receiving the knowledge transfer

Frequently asked questions

Does securing the infrastructure require shutting down the information system?

Structural changes (segmentation, AD hardening) are planned in phases and carried out within maintenance windows agreed jointly, specifically to limit impact on business operations.

What happens after the engagement ends?

Knowledge is transferred to the designated internal teams, along with operational documentation. Day-to-day operation of the secured infrastructure then returns to your teams, unless a separate service contract is set up.

How are hardening priorities chosen?

Gaps identified against the CIS Benchmarks are ranked by actual exposure and potential impact on your environment, to build a phased migration plan rather than an unprioritized list of recommendations.
