CST VerdictShort answer
Enterprise security teams managing cryptographic decay across complex supply chains need Quantanaut because it finds broken encryption and outdated TLS configs that vulnerability scanners skip entirely. The agentless discovery model means you map cryptographic risk using existing tool data without new agents, and the structured PQC transition guidance directly addresses NIST CSF 2.0's GV.SC supply chain requirement. Skip this if your organization hasn't inventoried cryptographic assets yet; Quantanaut assumes you know what you're protecting. Enterprise security teams preparing for post-quantum cryptography migration should start with AQtive Guard, which maps cryptographic exposure across your entire infrastructure and identifies which assets need rekeying first. The platform covers NIST PR.PS and PR.DS through cryptographic vulnerability mapping, giving you the threat inventory most organizations lack before they touch quantum-safe algorithms. Skip this if you need certificate lifecycle automation for today's RSA and ECDSA environments; AQtive Guard is built around tomorrow's problem, not managing your current PKI operations.
