Autonomous Security Layer
Inline visibility with air-gapped out-of-band communications.
Architectural principles
Designed for operationally sensitive environments.
Operational technology environments are often geographically distributed, legacy-heavy, air-gapped, and intolerant to disruption. Many critical assets operate with limited connectivity, physical exposure, and infrastructure constraints conventional cybersecurity tooling was never designed to accommodate.
P-X provides passive, infrastructure-independent visibility for environments where continuity, operational integrity, and autonomous resilience are non-negotiable.
Real autonomy is achievable
Passive by design
No agents, active polling, or intrusive deployment requirements. No increase in attack surface and no risk of interference.
Autonomous communications
Independent communications architecture designed to remain operational during outages or infrastructure disruption.
Sovereign technology stack
European-developed hardware and software with full-stack architectural control.
Infrastructure independent
Designed without dependency on cloud availability, telecom infrastructure, or shared operational networks.
Ecosystem integration
Designed to integrate with SOC, SIEM, XDR, Splunk, Azure, AWS, and related enterprise platforms.
Operational integrity
Built for environments where continuity, safety, and system integrity are non-negotiable.
Integration ecosystem
Platform & delivery
Delivered as an integrated resilience platform.

P-X combines proprietary hardware, software, and operational services into a long-term platform approach designed for continuity, lifecycle support, and operational simplicity.
Subscription-oriented delivery
Hardware, software, and operational support delivered as a long-term platform relationship.
Long-term operational partnership
Built around continuity, deployment reality, and lifecycle support rather than one-off procurement.
Lifecycle support
Designed for environments where technology lifecycles and operational lifecycles do not move at the same speed.
Low operational friction
A platform approach intended to reduce deployment complexity and avoid unnecessary changes to critical infrastructure.
Scalable deployment
Suitable for distributed operational environments, field assets, and sensitive sites.
Existing ecosystem integration
Intended to feed trusted telemetry into existing SOC, SIEM, XDR, and cloud security workflows.
Proven in practice
Operational credibility demonstrated.
Independent validation from operators and experts working with sensitive infrastructure environments.
“The system allowed us to establish monitoring capabilities without introducing additional operational risk.”
— Security Lead, National Gas Infrastructure Operator
“Maintaining separation from operational infrastructure was a fundamental requirement.”
— CISO, European Water Authority
“Infrastructure independence during outages and crises was a key differentiator.”
— Programme Lead, National Bridges & Lock Infrastructure
10+ Years Development
A long-term engineering trajectory across multiple hardware generations, software components, and operational validation contexts.
NIS2 & CRA Relevance
Relevant to organisations facing increasing European requirements for resilience, accountability, supply-chain control, and risk-based security.
International Patents
Internationally recognised intellectual property supporting the uniqueness of the P-X architecture.
Certification References
Relevant standards and certification references across hardware, safety, electromagnetic compatibility, and cybersecurity assurance.
Sovereign Technology
European-developed hardware and software with architectural control over the technology stack and supply-chain visibility.
Use Cases
Validated in critical operational environments.
P-X technology has been validated in operationally sensitive environments where continuity, safety, and infrastructure resilience are fundamental requirements.
Nuclear environments
Nuclear environments require deterministic operations, strict segregation and absolute control over change.
Conventional security tooling often conflicts with air gaps, certification requirements and operational integrity. P-X provides passive, independent observability without introducing additional attack surface or interfering with critical systems.
Water infrastructure
Water infrastructure consists of geographically distributed operational assets with limited visibility and fragile communications.
Remote sites are often physically accessible, while disruption can impact flooding control, drinking water availability and critical mobility infrastructure such as bridges that emergency and security services depend on during crises.
P-X enables autonomous local monitoring, even in isolated operational environments.
Gas distribution
Gas distribution environments require deterministic behaviour where interruptions or instability can trigger emergency shutdown procedures with operational and economic consequences that can outlast the shutdown window itself.
Operational sites are geographically dispersed, physically accessible and often dependent on isolated or legacy infrastructure.
P-X enables passive visibility inside segmented operational networks without introducing additional operational risk.
Manufacturing
Modern manufacturing depends on continuous operations where disruption to a single production environment can impact entire supply chains.
Many plants operate fragmented or inherited technology landscapes with isolated machine networks, legacy systems and limited central connectivity.
P-X provides protocol-agnostic visibility across distributed operational environments without requiring extensive infrastructure changes or additional cabling.
Offshore infrastructure
Offshore assets are remote, difficult to access and often minimally staffed.
When systems fail, determining whether the cause is malfunction, connectivity loss or cyber compromise can take significant time and cost.
P-X enables independent monitoring through its own autonomous communications, relaying operational status between nearby assets or directly back to shore.
Hospitals and laboratories
Hospitals and laboratories contain extremely dense operational technology environments where disruption can directly impact patient safety and continuity of care.
Many medical systems are certified devices that cannot easily accommodate embedded cybersecurity tooling or disruptive updates.
P-X adds passive, and optionally active, independent protection around critical systems without interfering with their operational or certification requirements.
