Essential Eight case study: mining tender readiness

This Essential Eight case study follows a 12-week security uplift for an Australian mining services contractor. Compuloop strengthened access, devices and site networks, then built the evidence needed for a tender review.

The starting point

The business challenge

The contractor had grown from a two-crew operation into a $60M contractor in eight years. IT grew reactively with it. When the business tendered for a major expansion project, the client's pre-qualification pack included a 40-question cybersecurity section on identity, patching, backup, incident response and supply chain risk. The contractor could answer perhaps six with confidence.

The submission came back non-compliant on security. Pricing was never opened. For a business whose growth model depended entirely on winning Tier 1 work, this was an existential commercial problem being managed internally as an IT annoyance.

What the assessment found

MFA on 6 of 180 users. Fourteen accounts with tenant-wide admin. One shared local administrator password across four offices and three mine sites. Two Windows Server 2008 R2 hosts still in production. Patch compliance at 34%. No incident response plan, no asset register, default 90-day audit retention.

Why it mattered

Three risks dominated. The shared local admin credential meant one infected site laptop could pivot into estimating, payroll and contract data. Unpatched internet-facing services had been exposed for 18 months — which triggered an emergency change on day three. And most at once damaging, the contractor could not evidence its controls, which is what actually lost the tender. Its security was better than its records. The client bought the records.

Network security, made visible

A firewall is one part of the wider network design. Segmentation, access rules and ongoing management matter alongside the hardware.

Identity decisions before access

Microsoft Entra Conditional Access evaluates signals and applies access controls. It helps explain the identity controls described in these projects.

The implementation

How this essential eight case study was delivered

01

Weeks 1–2 · Assess and prioritise

Essential Eight maturity assessment against ML1, asset discovery, identity audit, and a risk register ranked by commercial impact rather than technical severity.

02

Weeks 3–6 · Identity and email first

Entra ID P1, conditional access, MFA with number matching. Admin roles cut from 14 to 3 with separate privileged accounts. Legacy authentication blocked. DMARC to p=reject with DKIM and SPF corrected.

03

Weeks 5–9 · Endpoints and patching

Intune enrolment across 180 endpoints, update rings replacing ad-hoc WSUS, 2008 R2 hosts retired by migrating file shares to SharePoint and Azure Files. SentinelOne across all endpoints and site servers.

04

Weeks 8–11 · Site and network hardening

FortiGate policy review, LAPS, USB control, segmented site networks separating office, day-to-day technology and guest. Managed UniFi Wi-Fi with per-site isolation.

05

Weeks 10–12 · Evidence and assurance

Incident response runbook, asset register, 12 months of centralised logging, and a 26-page evidence pack mapping each control to the client questionnaire with live setup exports.

Practical obstacles, handled in stages

  • MFA on sites with poor mobile coverage. SMS MFA failed repeatedly in the remote sites. We deployed FIDO2 keys for 40 site staff and configured conditional access for defined offline windows.
  • Legacy estimating software requiring local admin. Packaged and published through Intune, with an elevation approval workflow for the two staff who genuinely needed it.
  • Cultural resistance. Site supervisors saw MFA as head-office overhead. We ran 20-minute toolbox talks on site, in work time, framed around tender eligibility — the thing they already cared about.

Controls that stay in place

The project also established repeatable processes. These controls support ongoing operation after the initial rollout.

  • Intune update rings — patching continuous, no monthly manual cycle
  • LAPS password rotation on all 180 endpoints
  • Conditional access enforced at every sign-in
  • FIDO2 key registration and self-service password reset
  • Phishing simulation on a rolling schedule with automated reporting
  • Evidence pack generated from live setup exports

Lessons for your business

  • Pre-qualification security questions are a procurement gate, not a technical exercise. Evidence is a deliverable from day one.
  • Identity is the fastest risk reduction per dollar. Fix MFA and admin sprawl before buying anything else.
  • Build the evidence pack once and maintain it. The second tender should take a day, not a quarter.
