IBM Quantum Safe helps you find your cryptography and plan remediation. QStrike proves what an adversary can exploit through provider-aligned validation. Offense vs. defense — here is where each approach leads.
The fundamental difference: IBM Quantum Safe is a defensive toolkit that inventories cryptography and guides remediation. QStrike is an offensive platform that demonstrates exploitability through forward-threat demonstration and provider-aligned validation.

If QStrike fails to identify any high or critical cryptographic vulnerability during a qualifying engagement, the published Challenge terms provide the program structure for qualifying engagements. We are not aware of a comparable challenge program from any competitor in this space.

Start with a QScout assessment intake to identify your quantum risk. Then let QStrike demonstrate what an adversary can actually exploit — through provider-aligned validation, governed by published $2M Challenge terms.
