Start a Post-Quantum Cryptography Migration Consultancy

1. 1

   Learn the standards and the real deadlines

   Study the NIST post-quantum algorithms (ML-KEM, ML-DSA and companions) and the transition guidance that deprecates RSA and ECC around 2030 with full disallowance by 2035, plus the sector rules flowing from EU and national roadmaps that start the clock in 2026. Your pitch is not quantum hype; it is a published compliance timeline with dates a CIO can be audited against.

2. 2

   Make cryptographic inventory your entry product

   Over 90 percent of enterprises cannot list where their cryptography lives: TLS endpoints, VPNs, code-signing, embedded libraries, hardware modules, vendor products, and long-lived archived data. Sell a fixed-scope discovery that produces a cryptographic bill of materials with an owner and an algorithm for every entry. This document is the prerequisite for everything else, and almost nobody has it.

3. 3

   Rank by harvest-now-decrypt-later risk

   The honest urgency argument: data stolen today can be decrypted later once quantum machines mature, so secrets with a shelf life of a decade (health records, financial data, government material, trade secrets) need quantum-resistant protection soonest. Rank the inventory by data lifetime and exposure, and let that ranking set the migration order instead of a vague everything-at-once plan.

4. 4

   Write phased roadmaps, not rip-and-replace plans

   Real migrations run through hybrid modes, library upgrades, certificate lifecycle changes, and vendor dependency chasing over multiple budget years. Deliver a roadmap with phases, cost bands, and decision points, and be honest that some legacy systems will be replaced rather than migrated. Cryptographic agility, building systems that can swap algorithms, is the durable recommendation to leave behind.

5. 5

   Target the buyers with auditors

   Banks, insurers, healthcare systems, defense suppliers, and government contractors will be asked about quantum readiness before anyone else. Speak at their industry events and write plainly about the timelines. One anchor client in a regulated vertical makes you the specialist that peers then call.

6. 6

   Stay in scope and partner for the build

   Position yourself as the assessment and roadmap layer, and partner with implementation teams and vendors for the heavy engineering. Advisory scope keeps your startup cost near zero and your margin high, and it keeps you credible: nobody believes one consultant re-encrypts an enterprise alone.
