OS imaging & hardening,
built once, kept compliant.

Standardised, hardened operating system images for Windows and Linux endpoints — deployed across your fleet, and kept that way.

Overview

One trusted image. Every endpoint.

Every endpoint that drifts from its standard build is a support ticket, an audit finding or an open door. Hand-built images, one-off fixes and inconsistent patching make fleets harder to secure and slower to recover.

We engineer golden images for Windows 10, Windows 11 and Linux — including thin-client estates — harden them against a defined security baseline, and automate deployment and re-imaging across your fleet. AI-assisted validation checks every build against the baseline, and drift detection flags endpoints that fall out of line.

The result is a fleet that is consistent, quick to rebuild and straightforward to evidence for audit.

Who it's for

A good fit if…

  • —You manage desktops, laptops or thin clients across multiple sites
  • —You are moving from Windows 10 to Windows 11
  • —Endpoints drift from their standard build over time
  • —You run kiosks, shared workstations or thin clients that must be locked down
  • —You need to evidence endpoint hardening for an audit or compliance framework
Outcomes

What you can expect

  • —One standard image per device role, built the same way every time
  • —Faster provisioning and recovery through automated re-imaging
  • —A smaller attack surface on every endpoint
  • —Continuous visibility of drift, patch and compliance status
Scope

What's included

01

Golden Image Engineering

Role-based master images for Windows 10/11 and Linux, produced by a scripted, repeatable build rather than by hand — so every rebuild is identical and every change is traceable.

  • —Role-based image design
  • —Scripted, version-controlled builds
  • —Application & driver packaging
  • —AI-assisted build validation
02

Fleet Deployment & Re-imaging

Automated rollout of images to new and existing devices, integrated with the endpoint management tools you already use, with staged deployment and rollback.

  • —Zero-touch & network-based deployment
  • —Staged rollouts with rollback
  • —Bulk re-imaging & recovery
  • —Works with your existing management stack
03

OS Hardening

Endpoint lockdown aligned to a defined security baseline, from firmware to user session — drawn from our Windows 10/11 and Linux thin-client hardening practice.

  • —BIOS-level lockdown
  • —Registry & GPO policy enforcement
  • —Unified Write Filter & kiosk / zero-footprint mode
  • —USB & removable-media control
  • —Attack-surface reduction
04

Patch, Driver & Firmware Management

Centralised, tested updates that keep images and deployed endpoints current without breaking the baseline.

  • —Patch testing & staged rollout
  • —Driver & firmware lifecycle
  • —Scheduled image refresh
  • —Compliance validation pipelines
05

Drift Detection & Compliance

Continuous comparison of every endpoint against its hardened baseline, with AI-assisted triage that separates meaningful drift from noise.

  • —Baseline drift detection
  • —AI-assisted triage & remediation
  • —Compliance reporting
  • —Audit-ready evidence
Engagement

How it works

01
Assess

We inventory your hardware, operating systems, applications and management tooling, and agree the security baseline.

02
Engineer

Golden images are built, hardened and validated for each device role, with every step scripted and versioned.

03
Deploy

Pilot groups first, then a staged rollout across the fleet with rollback ready at every stage.

04
Maintain

Patching, image refresh and drift detection keep the fleet aligned with its baseline.

Deliverables

What you receive

  • —Documented security baseline and hardening checklist
  • —Automated deployment and re-imaging workflows
  • —Patch and image refresh process
  • —Drift and compliance reports
  • —Runbooks and handover to your IT team
FAQ

Common questions

Which operating systems and devices do you cover?

Windows 10, Windows 11 and Linux, across desktops, laptops and thin clients. Tell us about your fleet and we'll confirm fit during the assessment.

Will this replace our endpoint management tools?

No. We work with the tools you already use and automate around them. Where there are gaps we recommend options, but you're not locked into anything of ours.

How is AI used in OS imaging?

AI assists with validating builds against the baseline, triaging drift and spotting anomalies across large fleets. Every change to an image or baseline is still reviewed and approved by an engineer.

Can you harden devices that are already deployed?

Yes. We can apply the baseline to existing endpoints in place or re-image them, depending on their current state and how much downtime you can accept.
