About the studio
Security you can check.
Matrix CR Studio finds the cryptography that quantum computers will break and helps regulated organizations replace it, with a record they can check.
Founded by Pablo Ramirez in Costa Rica. We work in English and Spanish, in Latin American and European time zones.
How we work
Five rules, each with something you can check.
We run the hardware we model
We run our own quantum circuits on IBM Quantum hardware instead of quoting someone else's threat model. 500 jobs are on record in our account, each listed with its ID. IBM job pages are visible only inside our account, so the list is a record we cannot edit, not a page you can open.
See the job ledgerWe correct ourselves in public
When one of our results does not hold, we say so on the site. 6 of our published claims are marked corrected, including results from March 2026 that turned out to have been computed on a simulator.
Read the claims registryYou can check our records without us
Our assessment tooling writes signed, linked records of its steps, and a free checker verifies them on your own machine, with no account and no network calls.
How Counterfoil worksWe measure systems people depend on
We look for failures in public infrastructure and report them where the maintainers work. 4 findings so far, each with a link you can open.

PQC-Scout, which finds post-quantum exposure in a codebase, is published under the Apache 2.0 license. Read it before you trust it.
PQC-Scout on GitHubWhat we will not do
Four lines we do not cross.
Touch your systems without written permission
Before an engagement we read only what is public. Anything that probes, scans or tests your systems starts after you authorise it in writing, and not before.
Sell offensive tooling
We build attack tooling to test our own defences. It is never a product and never leaves the studio.
Call a guess a finding
A result that has not been checked is labelled as such. When one of ours fails a check later, it is marked corrected on the claims registry, next to the original.
Give legal or investment advice
We produce evidence and assessments. Legal conclusions belong to your counsel, and nothing we publish is a recommendation to buy, sell or copy anything.
Who is accountable
A name on the work.
Pablo Ramirez founded the studio and answers for what it delivers. His background is network and systems engineering in healthcare, enterprise support and data-center operations. Security problems with anything we publish can be reported through our security contact, and we answer them in English or Spanish.
