Case Studies

Shaping a national quantum‑security and PQC strategy - For a government agency, we developed a quantum‑security strategy covering critical infrastructure, public services and national cryptographic policy. This included threat and impact assessment, sector‑by‑sector prioritisation, reference architectures for PQC adoption, and stakeholder playbooks for regulators, operators and vendors.

Designing a cryptographic modernisation roadmap - We supported a global financial institution in building its quantum‑security strategy: inventorying cryptographic assets across thousands of applications and systems, defining CBOM standards, assessing “harvest now, decrypt later” exposure, and designing a multi‑year PQC migration and crypto‑agility roadmap aligned with regulatory timelines.

A decentralized finance (DeFi) platform confronted a forward-looking challenge. The platform had seen rapid adoption, securing a significant value of cryptocurrency in its contracts, and its governance was managed by a decentralized community of token holders. The platform’s developers and community members started discussing the implications of quantum computing.

A national law enforcement agency realized that advances in quantum computing could jeopardize its sensitive data, communications, and digital evidence. The agency relies on encryption for everything from radio communications and surveillance data to case files and witness information. Leadership was concerned that a future quantum-equipped adversary might decrypt intercepted communications or access confidential records.

A cryptocurrency exchange, facilitating millions of trades per day and storing cryptocurrency on behalf of users, recognized a looming strategic threat: the advent of quantum computing. The exchange’s security team understood that if quantum computers reach a certain scale, the cryptographic underpinnings of blockchain and internet security could be undermined.

A financial firm specializing in digital asset custody was increasingly worried about the implications of quantum computing on its core business. As a custodian, the firm’s credibility rests on its ability to safeguard private keys that control digital assets worth billions; if those keys are compromised, the assets could be irreversibly stolen. They knew that most cryptocurrencies rely on cryptographic algorithms that could be broken...

A large healthcare provider network (spanning multiple hospitals, clinics, and research centers) handles millions of patient records and relies on a vast array of digital systems and medical devices. Patient privacy and safety are non-negotiable: health data must remain confidential for the lifetime of the patient (often decades), and critical medical systems (like surgical equipment, diagnostic machines, and monitoring devices) must be secure from tampering. The organization’s CIO and CISO had become aware of the looming quantum computing threat...

A national defense organization (comprising military and defense ministry stakeholders) recognized that quantum technologies could both threaten and enhance national security. On one hand, adversaries are pouring resources into quantum computing, which could eventually crack the encryption protecting military communications, classified data, and weapons systems.

A major metropolitan mass transit authority, operating an extensive rail and subway system, recognized that its ongoing digital modernization brought with it new cybersecurity challenges – especially with the looming prospect of quantum computers. Modern rail systems depend on secure communication: signaling systems send commands to trains, positive train control systems prevent collisions, and operational data about train positions and speeds flow constantly.

A pharmaceutical company, known for its innovative R&D pipeline, was looking for ways to maintain a competitive edge in discovering new drugs. The buzz around quantum computing’s potential in chemistry and material science had grown significantly. Executives were hearing that quantum computers might one day simulate complex molecular interactions far better than classical supercomputers – potentially shortening drug discovery times and uncovering novel therapies.
