Securing a Multi-Site Manufacturing Operation: ISA/IEC 62443 Implementation
Sites:
12 facilities
Timeline:
8 months
Devices:
450+ OT devices secured
The Challenge
A national food manufacturing company with 12 production facilities needed to achieve ISA/IEC 62443 compliance while maintaining 24/7 production schedules. Legacy OT systems dating back 15+ years presented unique security challenges.
Our Solution
Intrix deployed a phased network segmentation strategy aligned with the Purdue Model, implementing industrial firewalls and passive OT monitoring across all sites. We developed site-specific security zones while maintaining production continuity.
Measurable Results
Secure model development practices
Detected and remediated 3 previously unknown vulnerabilities
Improved incident detection time from days to minutes
Achieved ISA/IEC 62443 Security Level 2 across all critical zones
Reduced cyber insurance premiums by 25%
Retail
Preventing Payment Card Breach: Multi-Channel PCI DSS Implementation
stores:
85 locations
Timeline:
6 months to compliance
scans:
340+ quarterly scans annually
The Challenge
A retail chain with 85 stores and growing e-commerce operations struggled with PCI DSS compliance. They had experienced a minor card data exposure incident and needed immediate remediation plus ongoing compliance support.
Our Solution
Intrix implemented our PCI DSS Compliance-as-a-Service program, conducting an initial gap assessment, deploying quarterly vulnerability scans, implementing network segmentation between POS systems and corporate networks, and providing policy documentation support.
Measurable Results
Achieved full PCI DSS 4.0 compliance within 6 months
Implemented continuous monitoring of all 85 POS environments
Created sustainable compliance program with ongoing quarterly scans
Passed acquiring bank audit with zero findings

The Challenge
A regional bank needed to achieve compliance with APRA CPS 234 information security requirements while simultaneously upgrading legacy core banking systems. They required a risk management framework that balanced security with digital transformation.
Our Solution
Intrix partnered with the bank to develop a comprehensive information security program aligned with CPS 234, including risk assessments, third-party risk management, incident response planning, and board-level reporting frameworks.
Measurable Results
Full CPS 234 compliance achieved and maintained
Implemented third-party risk program covering 120+ suppliers
Zero material cyber incidents reported to APRA

Secure SDLC: DevSecOps Transformation for SaaS Platform
vulnerabilities:
78% reduction
Speed:
40% faster delivery
certification
SOC 2 Type II
The Challenge
A fast-growing Australian SaaS platform serving enterprise clients needed to embed security into its software development lifecycle without slowing delivery velocity. The engineering team was shipping code weekly but had no automated security testing, no secrets management, and a growing backlog of unpatched vulnerabilities flagged during a pre-SOC 2 readiness assessment.
Our Solution
Intrix partnered with the engineering and product teams to implement a DevSecOps programe covering automated SAST and DAST integration into CI/CD pipelines, secrets management, container image scanning, and developer security training. We ran a parallel SOC 2 Type II readiness programe, mapping security controls to Trust Services Criteria and supporting evidence collection throughout the audit period.
Measurable Results
78% reduction in open vulnerabilities within six months of pipeline integration
40% faster delivery cycle through automated security gates replacing manual review bottlenecks
Achieved SOC 2 Type II certification on first audit attempt
Zero critical findings in penetration test conducted post-implementation
Security training completed by 100% of engineering staff
SOCI Act Readiness: Energy Sector Risk Management Program
SOCI Act certified
Timeline:
9 months
Status:
Zero deficiencies in audit
The Challenge
A national energy infrastructure operator was required to comply with the Security of Critical Infrastructure Act 2018 within a defined regulatory timeframe. The organisation lacked a documented risk management programe, had limited visibility into third-party supplier risk, and had not conducted any formal cyber incident response exercises.
Our Solution
Intrix delivered a structured SOCI Act readiness programe covering Critical Infrastructure Risk Management Programe development, asset register compilation, third-party supplier risk assessments, and incident response plan development aligned with ASD reporting requirements. We facilitated tabletop exercises and provided board-level governance uplift through to the regulatory audit.
Measurable Results
Full SOCI Act compliance achieved within 9 months
Critical Infrastructure Risk Management Programe developed and approved by the board
Zero deficiencies identified during the regulatory audit
Incident response capability tested and validated through tabletop exercises
Board-level cyber risk reporting framework established
