About Quantum Security, PQC & Risk Services
Quantum computing is not a theoretical risk for someone else to worry about later. For any organisation that relies on public‑key cryptography, long‑lived data or widely connected infrastructure, it is now a strategic security concern.
The problem is two‑sided:
- Existing public‑key schemes will eventually be breakable by large‑scale quantum computers, creating “harvest now, decrypt later” risk today.
- The programmes needed to address this – PQC migration, crypto‑modernisation, crypto‑agility – are some of the largest and most complex transformations many CISOs and CTOs will oversee.
At the same time, new quantum technologies themselves – QKD links, quantum networks, sensing platforms – introduce fresh architectures and interfaces that must be secured from day one, often in environments already under regulatory and operational pressure.
Applied Quantum’s Quantum Security, PQC & Risk services focus on this entire landscape:
- understanding your true exposure to quantum threats, across IT, OT and products
- mapping and modernising your cryptographic estate and key management
- designing and governing PQC and crypto‑agility programmes that can actually be delivered
- validating and securing emerging quantum systems and networks
- translating evolving standards and regulatory expectations into practical policies and roadmaps
- giving CISOs, boards and regulators clear, defensible evidence of progress and risk reduction
We work with banks, FMIs, telecoms, critical‑infrastructure operators, technology vendors and government departments to move from generic “quantum risk” slides to concrete portfolios of work with owners, budgets and measurable risk reduction.
How we work
In security, PQC and risk engagements we treat quantum as a cryptographic, architectural and governance problem, not just a math problem. The goal is not a perfect future state: it’s a sequenced, defensible journey that regulators, boards and engineers can all live with.
Establish a Quantum‑Security Baseline
We start by understanding your current posture: how and where cryptography is used today (and how visible that is); which data, systems and interfaces are at risk from long‑term decryption or protocol breakage; what regulators, customers and counterparties already expect from you. This normally involves a mix of quantum readiness assessment, cryptographic inventory/CBOM work and risk assessment, resulting in a clear view of exposure and priorities.
Design And Sequence Your PQC & Security Programme
With a baseline in place, we help you design a roadmap, not just a list of scary problems: target architectures for PQC and hybrid cryptography; timelines that line up with regulation and your own technology cycles; programmes and workstreams that cut across IT, OT, products and vendors. We focus heavily on crypto‑agility and governance, so the move to PQC doesn’t become a one‑off project you have to repeat every time algorithms or requirements change.
Support Execution, Assurance And Adaptation
As you start implementing, we stay involved as an independent advisor and assurance partner: reviewing designs and implementations; providing quantum‑focused threat intelligence and inputs for risk committees; validating quantum systems and products. This gives CISOs, CTOs and boards a way to get fast, opinionated feedback as the landscape shifts – and to show regulators and auditors that decisions are anchored in a coherent, risk‑based approach.
Quantum Security Education
We design and deliver role‑specific quantum‑security education so that boards, executives, CISOs, security teams and architects share a common understanding of the risk and the plan. The focus is on your actual systems, regulations and timelines – not generic quantum talks – so people know what decisions they need to make and why.
- Tailored sessions for boards, executives, security leaders and technical teams, grounded in your sector and architecture.
- Scenario‑based workshops that connect quantum threats, PQC migration and crypto‑agility to real incidents, regulations and programmes.
- Reusable materials, narratives and Q&A support so your leaders can communicate confidently with regulators, partners and internal stakeholders.
Quantum Security Strategy
We help CISOs, CTOs and risk leaders define a coherent quantum‑security strategy that brings together PQC migration, crypto‑agility, key‑management, OT/IT integration and emerging quantum systems into one governed programme. The goal is a direction of travel that boards can approve, regulators can understand and engineering teams can execute against.
- Clarify strategic objectives, scope and risk appetite for quantum security across IT, OT, products and data.
- Define the structure of your quantum‑security and PQC programme: workstreams, governance, funding and accountability.
- Align technical roadmaps (PQC, CBOM, key management, system hardening) with regulatory timelines and broader cyber‑resilience initiatives.
Quantum Security & Resilience / PQC
We work with security and technology leadership to define your overall quantum security posture and strategy. That means understanding realistic quantum timelines, identifying critical domains (payments, identities, OT, products, interconnects), and designing quantum safe reference architectures that guide subsequent projects and investments.
- Clarify how quantum risk intersects with your existing cyber, resilience and digital strategies.
- Define target architectures for PQC, hybrid crypto and quantum‑safe patterns across IT and OT.
- Prioritise domains, systems and programmes for early action versus watch‑and‑wait.
Quantum Readiness Assessment (PQC & Cryptographic Risk)
This assessment focuses on post quantum cryptographic exposure: where and how vulnerable public key cryptography is used across your estate, how long data and systems need to remain secure, and how prepared your organisation is to manage the transition.
- Assess cryptographic posture, long‑lived data and “harvest now, decrypt later” exposure.
- Evaluate governance, processes, skills and vendor dependencies for PQC and crypto‑agility.
- Deliver a clear readiness baseline and prioritised set of remediation and planning actions.
Cryptographic Inventory & CBOM
Most organisations do not have a reliable picture of which algorithms, key sizes, protocols and libraries they rely on. We help you build that picture and turn it into a living Cryptographic Bill of Materials (CBOM) that can be used for PQC migration, vendor management and ongoing risk management.
- Discover and catalogue cryptographic usage across applications, infrastructure, products and OT.
- Design and implement CBOM data models, processes and ownership.
- Link inventory outputs to PQC prioritisation, procurement and change‑management workflows.
PQC Design & Implementation
We help you move from theory to concrete PQC deployments: designing hybrid and future proof architectures, selecting algorithms and parameter sets, and integrating them into infrastructure, applications, protocols and products.
- Design PQC and hybrid schemes appropriate to your use cases, risk profile and performance needs.
- Support pilots and phased rollouts in selected systems, products or connectivity domains.
- Provide guidance on interoperability, migration patterns and avoiding premature lock‑in.
Crypto-Agility Consulting
Even the best PQC choices today will evolve. Crypto agility is about designing systems and governance so you can change algorithms, key sizes, parameters and libraries with minimal disruption. We work with architects and engineers to bake this into your future state.
- Identify where rigid cryptographic design and technical debt block agility today.
- Define architectural patterns, interfaces and abstractions that support algorithm agility.
- Align processes, policies and ownership so changes can be made safely and repeatably.
Quantum Risk Assessment
A Quantum Risk Assessment is a business centric view of quantum threats. We connect technical cryptographic issues to real processes, services and regulatory consequences, identifying where quantum really matters and where it’s background noise.
- Map how quantum attacks could impact critical services, customers, markets and safety.
- Identify long‑lived data, systemic choke points and cross‑organisational dependencies.
- Prioritise risks and scenarios that should drive your PQC and quantum‑security roadmap.
Quantum Compliance & Regulatory Advisory
Regulators are increasingly explicit about PQC, crypto agility and long term confidentiality. We help you interpret these expectations, align internal policies and controls, and communicate your approach to supervisors, auditors and stakeholders.
- Map relevant PQC and quantum‑security expectations across jurisdictions and sectors.
- Align policies, standards and control frameworks with emerging regulatory language.
- Support interactions with regulators and auditors, including documentation and evidence.
Quantum Safe Key Management & Audits
Key management will make or break many PQC projects. We review and design KMS/HSM architectures, processes and controls for a world of hybrid algorithms, longer keys and potentially higher key rotation demands.
- Assess current key‑management practices, architectures and integrations for quantum readiness.
- Design enhancements to KMS/HSM, lifecycle processes and access controls to support PQC and hybrid schemes.
- Run targeted audits and reviews of key‑management domains to uncover and remediate weaknesses.
Quantum Threat Intelligence
We provide focused quantum related threat intelligence, not generic feeds: what matters for your sector, your tech stack and your regulatory context. That includes developments in attack techniques, HNDL activity, standards progress and the vendor/solutions landscape.
- Track quantum‑related developments relevant to your assets, geographies and counterparties.
- Translate technical and ecosystem changes into clear implications for your risk posture and plans.
- Provide regular briefings and scenario inputs for CISOs, risk committees and boards.
Quantum Systems Validation & Verification
As quantum systems and quantum enabled networks come online, they must be assessed and validated like any other critical infrastructure – with attention to classical–quantum interfaces and long term security assumptions.
- Design validation and test approaches for quantum systems, networks and “quantum‑safe” products.
- Assess security, reliability and performance, with emphasis on integration points and key‑management.
- Provide independent opinions on readiness for pilot, scale‑up or regulatory exposure.
