cyberzero Quantanaut is a cryptographic intelligence platform designed to identify and map hidden cryptographic risks across an organization's infrastructure, vendor ecosystem, and supply chain. The platform targets security leaders, architects, CISOs, and procurement teams who require visibility into cryptographic exposure that is not surfaced by conventional security tools. It is built to support the transition to post-quantum cryptography (PQC) by illuminating encryption weaknesses before quantum computing renders current algorithms obsolete. Key focus areas include: - Detection of broken certificate chains - Identification of outdated TLS configurations - Discovery of unknown or unvetted vendor algorithms - Mapping of cryptographic risk across infrastructure and third-party supply chains - Structured models and visualizations to support strategic decision-making Quantanaut operates without deploying agents or adding endpoint feeds. Instead, it works with existing data and tools already present in the environment, extracting structured cryptographic insight from them. The platform was developed in Canada, drawing on experience with government, defence, and critical infrastructure clients. It is positioned as a cryptographic intelligence layer rather than a traditional scanner, intended to help organizations understand and manage what is described as "cryptographic debt" — accumulated, unmanaged encryption risk embedded across systems and vendors. A companion product, the PQC Readiness Profile, is also offered by cyberzero alongside related consulting services covering zero trust architecture, cloud hardening, cryptographic evaluation, and post-quantum cryptography readiness.
