ISARA is a cybersecurity company headquartered in Waterloo, Ontario, Canada, founded by leaders from BlackBerry's security division with cryptography researchers from the University of Waterloo. The company focuses on cryptographic modernization and quantum-safe security, helping enterprises and government organizations manage cryptographic risk and prepare for the security implications of quantum computing. ISARA offers two primary products: ISARA Advance®, a cryptographic inventory and risk assessment tool, and ISARA Radiate™, a quantum-safe toolkit. Their approach to cryptographic modernization is structured around three phases: Discovery (building visibility into cryptographic assets across environments, devices, systems, and applications), Assessment (evaluating algorithm weaknesses, certificate expiry exposures, and overall cryptographic posture), and Modernization (transitioning from legacy cryptography to hybrid and quantum-safe systems). The company addresses threats such as "Harvest Now, Decrypt Later" attacks, where adversaries collect encrypted data today to decrypt it once quantum computers become capable of breaking current cryptographic algorithms. ISARA supports crypto-agility, hybrid certificate development, and alignment with NIST post-quantum cryptography (PQC) standards. Their target market includes highly security-conscious enterprises and government organizations responsible for protecting critical systems, long-lived data, and embedded or OT infrastructure. ISARA participates actively in global PQC standards bodies and hosts executive roundtable events across the US and Canada to facilitate peer dialogue on quantum-safe readiness strategies.
