Secure by Design. Resilient by Nature.
At Quad, security isn't just a feature—it's foundational. We build enterprise systems with robust security, privacy, and compliance built into every layer, ensuring your operations remain protected and resilient.
Secure
An agentic trade-and-tax platform built by Quad and deployed into production at HMRC to process live declarations.
The first system of its kind to receive formal regulatory clearance for autonomous compliance decision-making in the UK.
Most firms talk about responsible AI. We have systems regulators have formally recognised.
There is a meaningful difference between a vendor that has built an agentic prototype and a vendor that has shipped agentic systems into a regulator's own infrastructure. The HMRC case is that difference made concrete.
Architecture review
Layered AI walked through with regulator architects. Evidence schema and policy codification scrutinised against statutory expectations.
Pilot integration
Direct submission pipeline established. Sample declarations submitted, reconciled, and audited against ground truth.
Formal recognition
Examination of operating practice, incident handling, and audit trail completeness. Recognition granted for full production submission.
Multi-state rollout
EC integrations extended into additional member states. Pattern proven across jurisdictions and regulatory regimes.
Quad is the UK R&D Lead for the European Commission's EUREKA OpenLogistics initiative — shaping the global infrastructure that supply chains, customs and regulatory compliance will run on.
Active applied R&D — not advisory. Producing the open standards and open-source tooling that the next generation of regulated logistics infrastructure will be built on.
EUREKA is an intergovernmental R&D and innovation network of 48 countries and the European Commission. Quad holds the United Kingdom R&D Lead position for the OpenLogistics initiative — active, funded applied research and development with global implications for how supply chains, customs, taxation and regulatory compliance infrastructure are designed, standardised and operated.
This is not standards-committee attendance or advisory engagement. It is active R&D at the frontier — producing reference implementations, open-source tooling, and open standards that any operator globally can adopt. Quad brings its Layered AI architecture and its live HMRC / EC deployment experience directly into this context.
The implications reach beyond trade: the open standards emerging from this work will shape how AI-driven regulatory compliance is implemented at a global scale, across taxation, customs, trade facilitation, and the interoperability of national regulatory systems.

Global collaboration & innovation
Multi-nation R&D driving cutting-edge innovation across trade, logistics and compliance technology.
Your AI should run on infrastructure your regulator can examine — not a hyperscaler's black box they cannot.
Sovereign AI is not a marketing term. For a regulated firm, it is a risk management position: who controls the compute, where does the data reside, what happens when your infrastructure provider changes its terms, and can your regulator actually inspect what is running? Quad has the architecture, the infrastructure partnerships, and the deployment experience to answer all four questions cleanly.
What "Sovereign AI" actually means for a regulated firm.
Most enterprises that deploy AI agents do so on public hyperscaler infrastructure, under shared tenancy, with contractual terms that can change unilaterally, in data centres whose location is determined by the provider's commercial optimisation — not by your GDPR obligations, your FCA requirements, or your DORA resilience posture.
For a firm in financial services, healthcare or global trade, that is not a technology choice. It is a compliance exposure. Your regulator cannot inspect infrastructure they do not have jurisdiction over. Your evidence substrate cannot satisfy data-residency obligations if it sits outside your designated jurisdiction. And your operational resilience posture is only as strong as an SLA your hyperscaler can terminate.
Quad builds and operates Layered AI deployments on sovereign, dedicated, bare-metal infrastructure — physically located in your jurisdiction, exclusively tenanted to you, with no shared-compute exposure. We work with advanced infrastructure partners that operate interconnected, carrier-neutral data centres across the UK and EU, enabling low-latency sovereign AI deployments that sit inside your regulatory perimeter, not outside it.
Data residency by architecture
Every data store in the polyglot evidence substrate is physically located in your designated jurisdiction — UK, EU member state, or both. Not configured in a console. Enforced by infrastructure.
Dedicated, bare-metal compute
No shared tenancy, no noisy-neighbour risk, no hyperscaler dependency. Your agents run on dedicated hardware in interconnected, carrier-neutral facilities with direct cross-connects to your existing infrastructure.
Regulator-inspectable by design
Your infrastructure configuration, your audit records, and your operational controls are yours to present to an examiner. No referral to a third-party cloud provider's compliance team. No shared-responsibility gap.
Model portability & independence
Foundation models are a swappable component in Layered AI. Your sovereign deployment is not locked to a single model vendor. When a better model emerges, or a model is deprecated, you move — the architecture stays.
DORA-grade operational resilience
Interconnected, multi-site sovereign infrastructure designed to DORA operational resilience expectations — RTO, RPO, and ICT third-party risk obligations met by infrastructure design, not SLA hope.
- Shared-tenancy compute — no hardware exclusivity
- Data residency configured in a console, not enforced by infrastructure
- Contractual terms subject to unilateral change
- Regulator examination requires hyperscaler cooperation
- Operational resilience bounded by shared-infrastructure SLA
- Model lock-in — switching costs are architectural, not just commercial
- Jurisdiction determined by provider's commercial infrastructure map
- Dedicated bare-metal compute — exclusively tenanted to you
- Data residency enforced at the infrastructure layer — UK or EU by design
- Infrastructure under your contractual control, portable to alternative facilities
- Regulator can examine your infrastructure directly — no third-party in the chain
- DORA-grade resilience by architecture, across interconnected sovereign sites
- Model portability built into Layered AI — swap without re-engineering
- Jurisdiction determined by your regulatory obligations, not our convenience
Compliance is not a checklist we wave at procurement. It is the architecture.
Quad holds and aligns to the frameworks below at the organisation level — and bakes their requirements into every Layered AI deployment. Held means a current attestation. Aligned means operating to the standard with evidence on request. Ready means controls operating, formal step pending.
SOC 2 Type II
Independent attestation of security, availability, processing integrity, confidentiality and privacy controls — operating over a period.
ISO/IEC 27001
Information security management system certified to the international standard. Annual surveillance, three-year recertification.
UK GDPR • GDPR
Data controller and processor obligations fully implemented. DPO appointed. DPIAs run at deployment design-time.
Cyber Essentials Plus
UK government-backed cyber hygiene certification with independent technical verification of controls.
EU AI Act
Operating to high-risk system obligations: risk management, data governance, transparency, human oversight, accuracy & robustness, logging.
HIPAA
Administrative, physical and technical safeguards mapped. Business Associate Agreement available for in-scope deployments.
DORA
Operational resilience controls aligned to the Digital Operational Resilience Act — ICT risk, incident reporting, third-party risk management.
FCA • PRA SS1/23
Model risk management framework operating to PRA Supervisory Statement 1/23 expectations — inventory, validation, monitoring.
MHRA • EMA • ICH
Pharmacovigilance and clinical operations aligned to ICH-GVP, ICH-GCP and equivalent UK/EU regulator expectations.
PCI DSS
Controls mapped to PCI DSS v4.0 for deployments handling cardholder data, with scope minimisation by architecture.

ISO/IEC 42001
AI management system controls designed and operating — certification audit pathway initiated. Internal evidence available on request.
How each framework lands on a specific layer.
Compliance is an emergent property of the architecture — not a deliverable bolted on afterward. Each regulation maps to a specific Layered AI tier, and the evidence to satisfy it is produced as a continuous by-product of operation.
If a regulator asks for evidence, we can produce it from the evidence substrate, by design — not after a frantic week of forensic reconstruction.
Evidence layer — EU AI Act Art. 12 (logging) • GDPR Art. 30 • SS1/23 model inventory
The polyglot evidence substrate satisfies logging and record-keeping obligations across multiple frameworks. Structured audit records, object storage, versioned policy state, and lineage graph — one model, many regulators.
Guardrail layer — EU AI Act Art. 10 (data governance) • GDPR Art. 5 (accuracy) • MHRA E2B
Authoritative retrieval from government corpora enforces data quality and provenance obligations. Source attribution is mechanical, not editorial.
Policy layer — EU AI Act Art. 9 (risk management) • Consumer Duty • ICH-GVP • AML
Statutory rules codified as machine-checkable constraints. Continuous update flow as regulation moves — same-day reflection of regulator change.
Action layer — EU AI Act Art. 14 (human oversight) • DORA incident response
Traced, attributed, reversible actions. Human approval gates where statute or risk demands. Every action written to the evidence substrate before confirmation of effect.
Five principles on every engagement. No exceptions.
Data residency by design.
Deployments default to UK / EU data residency enforced at the infrastructure layer — not configured in a console where it can be changed. No cross-border data flows without contractual and architectural basis.
The model is rented. The substrate is yours.
Foundation models are a swappable component. The evidence substrate, policy modules, and agent contracts are durable assets owned by you — portable across model vendors and infrastructure providers.
Human oversight is engineered, not assumed.
Approval gates, intervention points, and reversibility are designed in at L04. Not implemented as a wrapper on an autonomous loop that runs unchecked until something breaks.
No training on customer data.
Customer data is not used to train any model. Prompt content, retrievals, and outputs remain inside your tenancy. Contractually guaranteed and architecturally enforced.
Honest about limits.
We refuse engagements where Layered AI is not the right answer. We are happy to point clients toward narrower tools — or away from agentic AI entirely — when that serves them better.
Regulator-ready by construction.
If a regulator asks for evidence, we produce it from the substrate, by design. Not after a frantic week of forensic work. Not with a referral to a third-party cloud provider's compliance team.
"The difference with Quad is they show up with the evidence pack already drafted. Most vendors arrive with a demo. Quad arrive with the audit trail."
