Why Subsea Cable Security Matters

Submarine cables are among the most critical yet least visible infrastructure assets. A single cable disruption can affect millions of users, disrupt financial markets, and compromise national security communications.

Global Communications Backbone

Subsea cables carry the vast majority of international internet traffic, voice communications, and data transfers. Disruption creates immediate, widespread impact across multiple sectors and nations.

Energy Interconnections

Power interconnector cables enable cross-border electricity trading and grid balancing. As renewable energy grows, these links become essential for energy security and decarbonisation goals.

Financial Infrastructure

Global financial markets depend on low-latency subsea connections. Trading systems, banking networks, and payment infrastructure rely on cable availability and integrity.

Government & Defence

Diplomatic communications, intelligence sharing, and military coordination increasingly traverse commercial submarine cable networks, creating national security dependencies.

Cloud & Digital Services

Cloud computing, streaming services, and enterprise applications depend on subsea capacity. Regional cable outages can disrupt services for entire continents.

Limited Redundancy

Despite their importance, many regions have limited cable diversity. Concentrated landing points and shared routes create single points of failure that adversaries may exploit.

Threat Landscape

Subsea cable infrastructure faces a unique combination of physical and cyber threats that require specialised understanding and integrated security approaches.

Critical

Cable Landing Station Intrusion

Landing stations are attractive targets where cables transition from sea to land. Threat actors seek access to network management systems, traffic monitoring capabilities, and physical cable termination points.

Critical

Network Management System Compromise

Sophisticated actors target the systems that monitor and manage cable networks. Compromising these systems could enable traffic interception, service disruption, or intelligence gathering.

High

Supply Chain Vulnerabilities

Cable manufacturing, installation, and maintenance involve global supply chains. Component compromise or malicious modifications during production or repair create persistent risks.

High

Reconnaissance Operations

Increased observation of cable routes, landing stations, and repair operations suggests systematic mapping of vulnerabilities by sophisticated actors for potential future action.

Our Services

Comprehensive cyber-physical security services designed specifically for subsea cable operators, owners, and the critical infrastructure they support.

Cable Landing Station Security Assessment

Comprehensive evaluation of physical and cyber security controls at landing stations. We assess perimeter security, access controls, network segmentation, monitoring capabilities, and resilience against targeted attacks. Deliverables include prioritised findings and practical remediation guidance.

Network Management System Security

Security review of the systems that monitor, manage, and control submarine cable networks. We evaluate authentication mechanisms, access controls, logging and alerting, and the security of interfaces with operational technology and third-party systems.

Threat Intelligence & Monitoring

Curated threat intelligence focused on risks to submarine cable infrastructure. We track threat actor activity, emerging vulnerabilities, and geopolitical developments relevant to cable security. Includes integration support for your existing security operations.

Incident Response Planning

Development and testing of incident response procedures for cyber and cyber-physical events affecting cable operations. We help you prepare for scenarios ranging from network intrusion to coordinated attacks on multiple landing stations.

Supply Chain Security Review

Assessment of cybersecurity risks across the cable supply chain, from equipment manufacturers to installation contractors and maintenance providers. We help identify and mitigate risks from third-party relationships.

Regulatory Compliance Support

Guidance on meeting cybersecurity requirements under NIS2, national critical infrastructure regulations, and sector-specific obligations. We help produce audit-ready documentation suitable for regulatory discussions.

Our Approach

We combine deep understanding of submarine cable operations with cybersecurity expertise to deliver practical, implementable security improvements.

1

Understand Your Environment

We begin by understanding your cable network architecture, operational processes, existing security controls, and the threat landscape specific to your routes and landing locations.

2

Assess Current State

Structured assessment of security controls across physical, network, and operational domains. We identify gaps against industry frameworks and threat-informed requirements.

3

Prioritise Based on Risk

Not all gaps carry equal risk. We help you prioritise improvements based on threat likelihood, potential impact, and operational constraints.

4

Implement & Validate

Support implementation of security improvements and validate effectiveness through testing. We help build sustainable security capabilities, not just point-in-time compliance.
