PQC Migration
We upgrade the encryption that protects your data to new, quantum-safe methods, so it stays private even when powerful quantum computers arrive.
What is PQC migration?
Almost everything you do online, from logging in and paying to sending email, is protected by encryption: maths that scrambles data so only the right person can read it.
Today’s most common encryption relies on maths problems that normal computers would take thousands of years to solve. A large quantum computer could solve some of them far faster. Post-quantum cryptography (PQC) is a new set of encryption methods, published as standards by the US National Institute of Standards and Technology (NIST) in 2024, designed to stay secure even against quantum computers.
PQC migration simply means swapping your old encryption for these new methods, carefully and without breaking anything.
It’s like changing the locks on your house before a master key is invented. The new locks look and work the same for you, but the coming master key won’t open them.
Why this is worth your attention
Data stolen today can be read tomorrow
Attackers can copy encrypted data now and simply wait until quantum computers can unlock it. This is known as “harvest now, decrypt later”.
Deadlines are already set
NIST plans to phase out today’s vulnerable encryption from 2030 and disallow it by 2035. Upgrades across a business take time, so starting early matters.
Customers and partners will ask
Regulators, banks and large customers are beginning to ask suppliers how they plan to handle the quantum risk.
Four simple steps
-
01
Find
We locate where encryption is used across your apps, servers, cloud services and suppliers.
-
02
Prioritise
We rank what to fix first, based on how sensitive the data is and how long it must stay secret.
-
03
Plan
We choose the right quantum-safe methods for each system and write a step-by-step upgrade plan.
-
04
Upgrade & test
We help your team make the changes, starting with a small pilot, and check that nothing slows down or breaks.

Questions people often ask
Do quantum computers that can break encryption exist today? add
Not yet. But many experts expect them within the next decade or so, and data stolen today could be unlocked then. That is why preparation starts now.
Will this disrupt my systems? add
We plan changes in small steps and test each one first. Often the new methods run alongside the old ones during the switch, so nothing stops working.
Do I need to buy new hardware? add
Usually not. Most upgrades are software changes. We will flag any older devices that may need replacing.
