Post-quantum readiness
Quantum computers will break the encryption you use today.
The fix already exists. The hard part is knowing where your cryptography actually lives. Type in a domain and see which of its connections a quantum computer could open.
It reads only what's already public.
How it works
Everything happens from the outside, the same way a browser sees your site. No agent, no access to your systems.
Discover
We read the public Certificate Transparency logs to find every hostname a domain has certificates for, including the ones people forgot about.
Test
We open the same TLS handshake your browser makes and offer each endpoint only post-quantum key exchange. If it accepts, it is safe. If it refuses, it is not.
Inventory
Everything is compiled into a cryptographic inventory with a grade, exportable as a CBOM, the file format the US government told CISA to define.
Why it is already urgent
Harvest now, decrypt later
Attackers do not need a quantum computer today. They can record your encrypted traffic now, sit on it, and decrypt it the moment one arrives. Anything that has to stay private for a decade is already at risk. That is the part you can close today, and it is the first thing we check.

Standards are landing and deadlines are being set. We track what changes and what it means for the companies that have to answer for it.
- An AI found a weakness in a post-quantum candidate. The standards you use are fine.
- The post-quantum transition has a meeting point: Amsterdam, this December
- The government is starting to quantum-proof its ID cards
