Unidirectional systems
data diodes, unidirectional gateways, and architectures for controlled one-way transfer between security domains, including unidirectional applications within cross-domain solutions.
The headline remains visible. The six original Jadebrain arrows separate to reveal six technologies, then reassemble into the logo while the technology labels remain. The supporting heading appears as the logo returns.
Jadebrain helps you assess architecture options, solve complex integrations, and develop new unidirectional capabilities with specialist consulting and engineering support.
Industrial experience. Architectural depth.
We are a specialist consulting and engineering company focused on unidirectional technologies, with deep experience in industrial and operational technology (OT) environments. We design, integrate, and validate unidirectional systems that protect critical operations while preserving the data flows they require.
Our core capabilities
data diodes, unidirectional gateways, and architectures for controlled one-way transfer between security domains, including unidirectional applications within cross-domain solutions.
physical separation, integration of unidirectional boundaries into segmented architectures, and analysis of how compromise can propagate through alternate connections and administrative paths.
independent integrity monitoring, hardware roots of trust, trusted platform modules (TPMs), attestation, and hardware-assisted mechanisms for protecting and assessing systems.
Critical systems must exchange data with monitoring platforms, business systems, and external services without exposing sensitive operations to unnecessary risk. In industrial, government, and other high-assurance environments, conventional perimeter controls may need additional isolation or hardware enforcement.
The challenge is to preserve required information flows while restricting the paths through which a connected system could affect critical operations.
Unidirectional technologies enforce one-way transfer between security domains. Where reverse communication is not required, they can remove the return network path through that connection while supporting the outward flow of operational data.
Making this work requires an in-depth understanding of protocols, data flows, failure behaviour, and any alternate connections or access paths. We help operators make sound architectural decisions, vendors solve difficult integration problems, and technology teams develop and validate new unidirectional capabilities.
From a decision to a working system
For operators, vendors, integrators, and technology teams.
Architecture options, data-flow designs, and transition plans for unidirectional systems, including physical isolation and the treatment of required inbound communication or remote-access paths.
Architecture options · Data-flow design · Transition plan
Discuss your architectureTechnical requirements, vendor evaluations, procurement criteria, and acceptance requirements for unidirectional security technologies. Test plans, technical evaluations, and acceptance criteria for directionality, data completeness, failure behaviour, security assumptions, and alternate paths across the boundary.
RFP requirements · Vendor evaluation · Acceptance criteria
Discuss your requirementsIntegration designs, feasibility studies, prototypes, and experiments for unidirectional systems, industrial protocol adaptation, and supporting hardware-backed security mechanisms.
Integration design · Bounded prototype · Validation findings
Discuss your technologyFocused technical workshops, design reviews, and ongoing advisory on unidirectional technologies and their application for engineering, security, product, and leadership teams.
Translate applicable ISA/IEC 62443, NIS2, NIST SP 800-82, and NIST Cybersecurity Framework requirements into unidirectional architecture decisions, technical specifications, and validation evidence.
Recommendations start with the operation: required connectivity, failure behaviour, maintainability, and the consequences of compromise.
We make security assumptions explicit and define how they will be tested, with clear acceptance criteria and documented limitations.
We assess options across vendors and technologies. If a data diode or hardware mechanism does not fit the requirement, we say so.
Bring an architecture, an RFP, an integration obstacle, or a research question. We will define the decision, identify the evidence required, and structure a focused engagement around clear technical deliverables.
