Quantum computers work differently
Experts expect a capable machine in the 2030s. Once it arrives, data encrypted today can be decrypted looking backwards. What looks safe now may not survive the decade.
The plain-language guide
We find the encryption your business relies on — and check if it will survive the next ten years.
Quantum computers are coming, and they will break much of today's encryption. Kvantis helps you discover where you're exposed — and build a practical plan to fix it. No jargon required.
The problem
The locks on your digital doors were not built for tomorrow's computers.
Almost every business uses encryption to protect customer records, contracts, payments and internal messages. That encryption relies on maths today's computers can't solve fast enough — but tomorrow's can.
It isn't science fiction
Governments, banks and technology companies are already preparing. In August 2024, NIST finalised three post-quantum standards: ML-KEM, ML-DSA and SLH-DSA.
It isn't about today
A quantum computer doesn't need to exist yet to put you at risk. Attackers can steal encrypted data now and wait until they can read it — a tactic called "harvest now, decrypt later."
It's a business problem, not just a tech one
If your data must stay confidential for ten years, you are already on the clock — whether or not anyone in the building works in security.
Why this matters
If you keep sensitive data for years, this affects you.
Customer data
Personal details, accounts and transaction history stored under today's encryption could be decrypted later.
Contracts & deals
Long-term agreements, M&A documents and strategic plans may need to stay confidential well past 2035.
Health & HR records
Medical files, payroll and employee records have long confidentiality lifetimes and high regulatory stakes.
Payment systems
Card data, transaction logs and banking integrations use encryption that will need upgrading in the coming years.
Operational technology
Factories, power grids, transport and medical devices often run older cryptography that is hard to find and replace.
Regulatory exposure
DORA and NIS2 already require regulated organisations to document and manage their cryptography. A policy alone is not enough.
The hidden risk
Stolen today.
Decrypted later.
This is the part most people miss. An attacker doesn't need a quantum computer today to hurt you tomorrow. They just need patience.
Today
Attackers copy encrypted data they cannot yet read, and store it.
Est. 2029–2035
Quantum computers may reach the strength needed to break today's encryption.
The exposure
Everything taken in the meantime is decrypted retroactively — all at once.
The fix isn't to wait for quantum computers to arrive. It's to find your weak encryption now and start replacing it in a controlled, business-safe way.
What we do
We scan your systems, find the weak spots, and give you a plan.
Kvantis is an independent security service — no software to subscribe to, and we never move your data to our cloud. We run a structured audit and hand you a clear, evidence-based report.
Discovery
We map every place you use cryptography — websites, servers, apps, network devices, certificates and third-party services. Most teams are surprised how many they have.
Risk scoring
We score each finding by business impact, regulatory relevance and how long it takes to fix — so you see what matters first, not a long list of warnings.
Migration plan
We build a practical, phase-by-phase plan to replace weak encryption with modern, quantum-resistant alternatives — without breaking your systems.
Evidence pack
You get a signed, verifiable report you can show auditors, supervisors, insurers and your board. Every claim traces back to a real finding.
Who it's for
Anyone holding sensitive data for the long term.
Banks & insurers
Payment data, customer records and trading systems all carry long-term confidentiality obligations.
Healthcare
Patient records, clinical systems and medical devices must stay confidential for decades.
Energy & infrastructure
Power grids, transport networks and industrial control systems depend on encryption that is hard to upgrade.
Government & defence
Classified and citizen data need cryptographic evidence that will stand up to future scrutiny.
Law firms & professional services
Client files, contracts and M&A documents often need to stay confidential well beyond 2035.
SaaS & technology vendors
Customer backups, vendor integrations and product data can live in old encryption longer than expected.
It isn't only for regulated giants. A law firm with long-term client files, a SaaS company holding customer backups, or a manufacturer with devices in the field can all have exposure they haven't mapped yet. The audit scales to the size of the organisation.
Why Kvantis
Independent, EU-hosted, no lock-in.
We don't sell software
Many vendors want you on their platform for years. Kvantis delivers a service — we find the problem, document it, and help you fix it. You keep the outputs.
Your data stays with you
The audit runs inside your own infrastructure. Nothing is uploaded to our servers — which matters for banks, hospitals and anyone with strict data-residency rules.
We speak both languages
The same audit gives your board a plain-language summary and your engineers the technical detail. No translation layer needed.
We're built for this transition
The post-quantum standards are already published. The question is no longer "if" but "when and how" — and we help you answer it without disrupting operations.
