Terma Meridian Defence – Military and Critical Infrastructure Security

Cyber Defence Through Network Visibility and Control

Detect Threats Immediately. Keep the Mission Running

Real-time Network Monitoring for Defence and Critical Infrastructure Security

A perimeter-based cyber defence of your system, relying on firewalls and router protection, is no longer sufficient for modern threats. Advanced attacks, insider activity, and supply‑chain compromises often bypass the perimeter and operate silently inside the network. When something suspicious happens; a strange connection, a data spike, or an unauthorized attempt to access resources, Terma Meridian Defence triggers an alert before the issue spreads.

Detect early. Continuous monitoring and behavioral baselining surface abnormal behavior before it escalates into an incident.

Act Confidently. Prioritized, tailored alarms highlight critical events to support better decision-making and faster response.

Monitor Without Disruption. Deep packet inspection with no impact on network speed or throughput, and no blocking.

Operational Technology Cybersecurity for Defence Platforms and Critical Infrastructure

Terma Meridian Defence is designed for closed networks where system availability is critical for mission success, and where a cybersecurity tool must never become the point of failure.

It brings critical infrastructure cybersecurity and cyber network observability to variety of systems, including:

Naval command and control systems
Radar installations
Integrated air and missile defence
Critical infrastructure protection sites
Counter-unmanned aircraft systems (counter-UAS)
Radio dispatch and control room systems

Benefits

Early detection

Behavioral baselining and known threat patterns surface abnormal behavior before it becomes an incident.

Alarms you can trust

Native knowledge of operational system behavior keeps false positives to a minimum.

Zero impact on the mission

Deep packet inspection without blocking, delaying or affecting throughput.

Guided by standards

Developed with consideration for NATO CIS security requirements, NWS5 and the EU NIS2 Directive, with automatic event logging for audit and reporting.

Designed for ease of use

Real-time dashboard, geo-mapping and guided workflows for non-specialist operators.

Evidence at hand

Integrated forensics and one-click export packages for your SOC or accreditation authority.

Technology

Deep Packet Inspection Without Delay

Terma Meridian Defence acts as a 24/7 security monitor for your operational system providing early warning. It continuously analyzes all network activity, looking for signs of intrusion, misuse, or malicious behavior. Terma Meridian Defence is specifically designed to deliver deep packet inspection (DPI) without influencing network speeds or data throughput.

Visibility

Real-time security overview

All detected activity is transformed into clear, real-time security insights through an intuitive dashboard. Events, anomalies, and network behavior are visualized as they happen, giving you a live view of your operational environment. The system supports API integrations, allowing you to connect third-party tools, dashboards, or sensors. A modular widget-based layout lets you tailor the interface to your specific needs, ensuring relevant information is always front and center.

Response

From Alarm to Decision in One Click

When suspicious activity is detected, Terma Meridian Defence generates structured, actionable alarms designed to prompt immediate and coordinated response. Each alert is enriched with context and presented within a clear hierarchy, helping you quickly assess severity and relevance. Alarms are organized to support efficient collaboration, ensuring the right people can take the right actions at the right time.

Investigation

Forensic Event Analysis

Terma Meridian Defence provides forensic capabilities for post-incident analysis. You can quickly get an overview of connected nodes, communication patterns and network activity. Through deep inspection of captured data and event timelines, the system helps trace incidents back to their origin, understand their progression, and document findings with precision. With a single click generates an export package with key context and raw data, ready to share with a SOC or security experts for investigation.

Reliability

Monitoring Without Disruption

Built for sensitive operational environments, Terma Meridian Defence delivers continuous network visibility without blocking traffic or impacting performance, ensuring availability where uptime is critical. With NATO CIS accreditation, deployment is fast and frictionless, while the intuitive interface enables your team to adopt it with minimal training. Combined with streamlined incident response capabilities, Terma Meridian Defence helps you detect, understand, and act on threats before they escalate.

Efficiency

Efficient Incident Response

Terma Meridian Defence supports fast, action-oriented decision-making in operational environments. Clear traffic light indicators provide immediate status awareness, helping operators quickly identify and prioritize issues. Alarms include precise contextual information, including the physical location of affected network components such as switches. This enables efficient response, coordinated on-site intervention, and reduced disruption to mission-critical operations.

Strengthening Network Security and Compliance

Terma Meridian Defence helps meet network monitoring and security requirements defined in NATO CIS (AC/322-D/0048-REV3) and the EU NIS2 Directive. Supporting compliance with these frameworks strengthens visibility, resilience, and control across sensitive infrastructures. This alignment demonstrates the system’s robustness while enabling faster integration into high-security environments, helping organizations reduce approval timelines and deployment risks in mission-critical networks.
