| Quantum threat intelligence, open to everyone
SQOUT® is a knowledge base of attacks on quantum communication systems, such as quantum key distribution (QKD), and of the countermeasures against them. This open-access site shows the public part of SQOUT. You can use it without an account.
Here you can:
- browse the quantum threat matrix, which orders attack techniques by tactic,
- read each attack technique and countermeasure, with the scientific papers behind it,
- look up terms in the dictionary,
- read new analysis on the blog.
Every item on this site is released for public use.

What the full SQOUT platform adds
The full platform holds much more than this site. In October 2026, it covers 149 attack techniques, 132 vulnerabilities 194 countermeasures and 34 quantum protocols.
It also adds:
- full technique details: feasibility, required equipment, and links to hardware, software and protocols,
- vulnerabilities, products and threat actors,
- QBuilder, to model your own quantum communication device adn QNetwork to model your quantum network,
- QAnalyser, to find the weaknesses in that model automatically,
- QKill, to model attacks in several steps and calculate the risk.
