ISARA Corporation

ISARA builds the tooling organizations need to find out what cryptography they’re actually running and then migrate it before quantum computing makes it obsolete — a problem most enterprises don’t realize is a multi-year project until they start. ISARA Advance handles cryptographic discovery and risk assessment (scanning an environment to inventory where and how classical algorithms like RSA and ECC are used), while ISARA Radiate is a quantum-safe cryptography library and toolkit for building post-quantum support directly into products. A crypto-agile root certificate developed with Toppan Holdings and Japan’s National Institute of Information and Communications Technology (NICT) extends that work into certificate-authority infrastructure, letting CAs migrate from ECDSA to NIST’s ML-DSA standard without a disruptive rebuild.

Founded in 2015 in Waterloo, Ontario by BlackBerry security veterans working with University of Waterloo cryptography researchers, ISARA raised $11.5 million in seed funding from Quantum Valley Investments at launch and a further $10 million Series A from Shasta Ventures in 2018, for roughly $21.5 million in total disclosed funding. The company was an early contributor to NIST’s post-quantum cryptography standardization process, giving it a credibility position most PQC vendors that emerged after NIST finalized its standards in 2024 don’t have.

ISARA’s commercial reach now extends into the US public sector: Carahsoft began distributing ISARA’s solutions to federal customers via contracting vehicles including NASA SEWP V in 2026, and the company has a strategic partnership with The LightBridge Group targeting US government PQC migration and risk-management work. At roughly 24-40 employees, ISARA remains a specialist rather than a broad platform vendor, competing on technical depth in cryptographic migration rather than breadth of product.
