For years, security leaders have been told that preparing for post-quantum cryptography (PQC) would take years, cost millions and require deep in-house expertise. QuSecure Inc., the market leader in quantum-safe security, is proving otherwise with its new QuProtect R3, the industry’s first and only fully integrated, production-ready PQC platform designed to make encryption modernization simple for everyone. With the platform’s Reconnaissance innovation, a complimentary module for qualified companies, QuProtect R3 delivers instant visibility into vulnerable encryption across modern, legacy and cloud systems — a capability competitors cannot match. Security teams that once spent months and millions compiling a cryptographic bill of materials (CBOM) can now discover their encryption landscape in days, prioritize the highest-risk systems and act without disrupting operations.
