Quantum-Proof Encryption
Cryptographic inventory, exposure to harvest-now-decrypt-later, and a sequenced migration plan to post-quantum algorithms.
What the practice does.
Data encrypted today with RSA or elliptic curve keys can be recorded now and decrypted when a sufficiently capable quantum computer exists. If your data must stay confidential for longer than the migration will take, the exposure starts now.
The standards are settled: NIST published the first post-quantum standards in 2024, and governments have set migration deadlines. The hard part is knowing where your cryptography lives. That is where we start.
Deliverables.
Each item is something you keep: a document, a register, a plan. All of it is scoped and priced before the work starts.
Cryptographic inventory
Every place your organization uses cryptography: certificates, TLS endpoints, VPNs, code signing, HSMs, databases, backups, embedded devices and the libraries inside your software. Discovered with tooling, confirmed by hand.
Exposure assessment
Each system scored on data lifetime, algorithm, key length and the practicality of upgrade, so you know what is actually at risk from harvest-now-decrypt-later.
Crypto-agility review
How hard it is to change algorithms in your systems and vendors, and the architecture changes that make the next migration easier than this one.
Sequenced migration roadmap
What moves first, what waits, which vendors to push, and the hybrid configurations to deploy now. Mapped to the deadlines that apply to you, including Government of Canada and NIST timelines.
Vendor and procurement language
Contract clauses and questionnaire items so new systems arrive quantum-ready instead of adding to the backlog.
The four steps, applied.
The method is the same for every practice. This is what each step means here.
Systems, data classes and retention requirements in scope, plus the regulatory or customer deadlines you need to meet.
Automated discovery across networks, certificates, code and configuration, followed by manual confirmation of what the tooling found and what it missed.
A second analyst validates the inventory and the exposure scoring. Vendor claims are checked against documentation, not marketing.
The inventory as a living register, an exposure heat map, and a roadmap with sequencing, owners and cost ranges.
The situations this is built for.
You hold data that must stay secret for a decade
Health records, legal files, intellectual property, government information. If confidentiality outlasts the migration, the clock is already running.
A regulator, customer or parent company has set a deadline
Migration timelines are now written into policy and contracts. You need a plan with dates.
You are buying or building systems with a long life
Infrastructure, devices and platforms bought today will still be in service when the threat is real. Specify quantum-safe now.
Asked before most engagements.
When will quantum computers break RSA?
Nobody can give you a date, and you do not need one. The decision depends on how long your data must stay confidential plus how long migration takes. For many organizations that sum already exceeds the credible estimates.
Which algorithms should we move to?
NIST standardized ML-KEM for key establishment and ML-DSA and SLH-DSA for signatures in 2024, with further standards following. Most migrations begin with hybrid TLS and new certificate hierarchies, then move through VPNs, code signing and data at rest.
Is this only for large enterprises?
No. Smaller organizations often depend on a handful of vendors and platforms. The work is to inventory, confirm vendor timelines, and sequence the changes you control.
