Quantum Resilience

Cryptography quietly underpins everything your organisation does, and today's encryption has a publicly-confirmed migration deadline. Rossnet helps CTOs, CISOs, and Heads of Risk understand real exposure and build a realistic migration plan, grounded in the actual timeline rather than the vendor sales pitch.

The Quantum Resilience Gap

Planned Everywhere. Deployed Almost Nowhere.

Organisations know post-quantum migration is coming — few have started, and fewer still have a defined plan.

No Cryptographic Inventory

Most organisations cannot say where or how cryptography is used across their estate, which makes migration planning impossible to start, let alone sequence.

Harvest-Now, Decrypt-Later Exposure

Data with long confidentiality requirements — health records, IP, financial data — collected or intercepted today can be decrypted retroactively once cryptographically relevant quantum computing arrives.

Supply Chain & Procurement Risk

Regulated sectors, government, and defence-linked supply chains are beginning to require quantum-safe procurement; unprepared suppliers risk exclusion from future contracts.

Migration Timelines Are Longer Than Assumed

Realistic PQC migration runs an estimated 5–7 years for small enterprises, 8–12 for medium, and 12–15+ for large organisations with legacy complexity — not a short project.

The Regulatory & Standards Landscape

The migration timeline is now fixed

The technical standard is finalised and the national roadmap has dates attached.

NIST PQC Standards (FIPS 203, 204, 205)

The finalised international technical benchmark for quantum-resistant encryption and digital signatures, published August 2024 after an eight-year standardisation process. Already the reference point enterprise clients and regulators expect suppliers to work towards.

UK NCSC Migration Roadmap

The UK's three-phase national timeline: complete cryptographic discovery and a migration plan by 2028, execute priority upgrades by 2031, complete migration across all systems by 2035.

Sector & Supply-Chain Mandates

Mechanisms such as the US NSA's CNSA 2.0 (2030 deadline for National Security Systems) and emerging quantum-safe procurement requirements are already reaching UK organisations that sell into defence, government, or US-linked supply chains.

Investor & Board Pressure

"Harvest now, decrypt later" turns quantum exposure into a present-tense risk-disclosure issue for any board holding data with a long confidentiality shelf-life, not a future one.

Who It's For

Understanding exposure, evidencing readiness

CTOs & CISOs

Own the cryptographic estate and need a realistic, sequenced migration plan — not vendor hype or a "rip and replace" sales pitch.

Heads of Risk & Regulated Supply Chains

Need to start — or evidence — a post-quantum migration plan for board reporting, procurement requirements, or defence-linked contracts.

A discovery conversation will confirm whether a cryptographic inventory, a full migration roadmap, or board-level briefing is the right starting point.
