Capabilities
Deployment-Ready Platform

A deployment-ready cyber range platform designed to support both cloud and on-premise isolated environments, enabling rapid setup and operational use across defense and high-assurance contexts.

Military-Focused by Design

The platform is military-focused by design, reflecting real operational constraints, force structures, and mission-driven training requirements.

Technical Domains Covered

Our cyber range solution supports a broad set of technical domains commonly encountered in military and critical infrastructure environments, including the following:

  • Active Directory and enterprise identity infrastructure
  • Operational Technology (OT) environments
  • ICS / SCADA systems
  • Web application exploitation
  • Reverse engineering and malware analysis
  • IoT and embedded system exploitation
Scenario Design & Progression

Training and exercise scenarios are mapped to established frameworks such as the MITRE ATT&CK matrix, enabling structured execution, assessment, and reporting.

Scenarios span from beginner to advanced levels, supporting progressive skill development for operators with varying experience levels, from foundational training through complex, multi-stage operations.

Realism & Fidelity

Our cyber range is designed with high fidelity, informed by real-world military experience and operational expertise, to ensure scenarios reflect realistic adversary behaviour, system complexity, and mission pressure.

This Live, Virtual, and Constructive (LVC) enabled approach enables meaningful training, validation, and rehearsal under conditions that closely resemble live operational environments.

Services
  • Cyber training and mission rehearsal
  • Capability validation and readiness assessment
  • Joint and multi-domain exercise support
  • Operational experimentation and scenario execution
Capabilities
Adversary Emulation & Campaign Design

Sophisticated adversary emulation against command systems, platforms, and mission networks, reflecting advanced and persistent threat behaviour across military-relevant environments. Engagements are designed as objective-based campaigns, replicating realistic attack progression and operational constraints.

Targeted R&D on Mission Technologies

Targeted research and development activities focused on priority technologies, protocols, and mission-critical systems to identify exploitable weaknesses ahead of adversaries, and to understand how vulnerabilities translate into operational impact.

Operator Training & Enablement

Training activities focused on adversary tradecraft, tools, and procedures relevant to evolving threat pictures, supporting readiness across different skill levels.

Services
  • Red Teaming: Full-scope adversary emulation and objective-based attack paths (end-to-end).
  • Adversary Simulation & Emulation: Threat-led campaigns aligned to relevant tactics, techniques, and procedures, including realistic ransomware and data theft scenarios.
  • Purple Teaming: Joint offensive–defensive exercises enabling detection and response tuning.
  • Penetration Testing: Comprehensive testing across a range of environments and attack surfaces, including:
    • External network testing
    • Internal network testing
    • Web applications and APIs
    • Mobile applications and thick clients
    • Cloud environments and container/Kubernetes platforms
    • Wireless networks and IoT systems
    • Social engineering
    • Physical security assessments
  • Attack Path & Exposure Analysis: Attack path mapping and breach & attack simulation to validate exposure and defensive coverage.
Capabilities
Contested & Degraded Operations

Defensive cyber operations designed for mission-critical networks operating in contested and degraded environments, combining rapid incident response with proactive threat hunting and intelligence-led defence.

Strategic & Tactical Incident Response

Strategic and tactical incident response spanning from first notification through containment, eradication, recovery, and post-incident validation. Support includes operation in austere and high-risk environments, with structured escalation and playbook-driven response.

Cyber Threat Intelligence

Strategic, operational, and tactical cyber threat intelligence focused on military-relevant and state-sponsored threat activity, supporting defensive prioritisation, response planning, and mission-aware risk management.

Threat Hunting & Compromise Assessment

Proactive threat hunting across enterprise, operational technology, and mission systems to detect adversary presence before operational impact. Includes environment-wide compromise assessment and post-incident clean-up validation.

Detection Engineering

Detection engineering, gap analysis, and tuning activities, including ATT&CK-aligned coverage mapping to improve detection fidelity and response coordination over time.

Services
  • Incident Response: Ad-hoc response and retainer-based IR options, with active playbooks and structured escalation.
  • Digital Forensics & Root Cause Analysis: Investigation support to understand scope, cause, and operational impact.
  • Threat Hunting & Compromise Assessment: Proactive hunts and environment-wide compromise assessment, including post-incident validation.
  • Cyber Threat Intelligence: Strategic, operational, and tactical intelligence support tailored to military-relevant threats.
  • Detection Engineering: Detection development, gap analysis, tuning, and ATT&CK-aligned coverage mapping.
  • Blue & Purple Teaming: Joint offensive–defensive exercises to harden the defensive posture against realistic adversary tactics, techniques, and procedures.
