Why we are called Qopanza

Today's encryption has an expiry date

The maths protecting your traffic — RSA, elliptic curve — is safe against ordinary computers and breakable by a large enough quantum one. That machine does not exist yet. The deadline for replacing the maths does.

Which makes it a problem now, not later

Encrypted traffic can be recorded today and unlocked years from now. Anything that has to stay private for a decade — health records, contracts, anyone's identity documents — is already exposed to whoever is patient enough to keep a copy.

And the fix starts with a list

New standards were finalised in 2024, and the deadlines run to 2033. Every plan for meeting them begins the same way: know which cryptography you have and where it lives. Almost no organisation does. Building that list is the other half of what we do.

The same scan that reads your bundle can list the cryptography your app depends on. One is urgent today; the other has a date on it.

What this scan does, and does not do

We read only what your site already sends to anyone who visits it. We do not log in, do not touch your servers, and never store your source code. It needs your web address and nothing else.
