Project Security Integration
The situation
DeltaPAE is a coal mine and power station on the NSW Central Coast with 350+ employees. New ownership arrived with an aggressive technology transformation agenda — cloud migration, new operational technology systems, and a modernisation programme running across multiple simultaneous projects.
The internal security team was two people. Enterprise-level security demands were arriving faster than a small internal team could address them. New ownership needed confidence that security was being embedded across every project — not checked at the end.
The challenge wasn't finding vulnerabilities. It was building a security function capable of keeping pace with a fast-moving transformation programme, without the time or budget for additional permanent headcount.
What Cliffside did
Cliffside became DeltaPAE's embedded security office — operating as an extension of their internal team rather than an external consultant. We steered the security roadmap, pressure-tested vendor proposals, validated cloud architecture decisions, and provided the security leadership function that the internal team couldn't resource alone.
Every major project — cloud migration, OT modernisation, infrastructure refresh — had Cliffside security input from architecture through to delivery. No surprises at go-live. No security findings that delayed projects. No expensive rework.
What we delivered
- Embedded security function operating as an extension of the internal team
- Security architecture input across all simultaneous technology projects
- Vendor assessment and pressure-testing for all major procurement decisions
- Cloud migration security architecture and validation
- OT/IT convergence security framework for mining and energy operations
- Board-level security reporting and risk visibility
- Security awareness programme for operational staff
- 200% effective increase in security team capacity — zero additional headcount
The outcome
Enterprise-level security capability, from day one of the engagement. A 2-person security team operating with the reach and effectiveness of a security function four times that size — steering a multi-programme transformation without a single project delayed for security reasons.
