Post-Breach Technology and Security Transformation 

Overview 

Following a major cyber security breach, this maritime transport organisation needed to rebuild trust, reduce risk, and stabilise operations across both its fleet and shore-based sites. The environment was complex, with real-time, safety-critical systems that could not afford downtime. 

The Challenge 

• Outdated and inconsistent systems across ships and shore locations 
• Limited visibility of cyber threats and security incidents 
• Safety-critical systems exposed to risk 
• No formal disaster recovery or governance processes 
• Increasing reliance on operational technology without secure design 

What Was Delivered 

• Replaced legacy infrastructure with a secure, modern network across all locations and vessels 
• Introduced clear separation between corporate IT and operational ship systems 
• Designed a resilient ship-to-shore connectivity model with secure, automatic failover 
• Removed unsupported systems and built a more reliable, high-availability environment 
• Implemented disaster recovery plans and tested business continuity procedures 
• Introduced 24/7 security monitoring and improved threat detection capabilities 
• Established formal governance, compliance, and change control processes 
• Secured a wide range of operational systems, from passenger platforms to safety-critical equipment 

The Outcome 

• Significant reduction in cyber risk across both IT and operational environments 
• Improved reliability and uptime for fleet operations 
• Greater visibility and faster response to security threats 
• Standardised technology across the organisation  
• Shift from reactive firefighting to proactive security management
