The Quantum Blind Spot: Seeing Cryptography Without Decrypting It

Learn how Infosys Cyber Next helps enterprises gain real-time visibility into post-quantum cryptography (PQC) risk.

 

As organizations prepare for the quantum era, many are focusing on post-quantum cryptography (PQC) migration strategies, cryptographic modernization, and crypto-agility initiatives. Yet a fundamental challenge remains unresolved:

What cryptography is running across the network today?

Traditional crypto inventories built from spreadsheets, Configuration Management Database (CMDB) records, code reviews, and asset scans provide only a snapshot in time. As environments evolve, these inventories quickly become outdated, leaving organizations with limited visibility into their true cryptographic posture.

Cryptographic risks often reside in unexpected assets, including legacy applications, third-party integrations, unmanaged systems, and shadow IT, making them difficult to identify through traditional inventories alone. Encrypted Traffic Analysis (ETA) helps close this visibility gap by examining traffic metadata and behavioral characteristics, such as TLS versions, cipher suites, certificate chains, and key-exchange mechanisms, without decrypting the underlying data. These observable attributes create a cryptographic fingerprint that provides real-time insight into an organization’s cryptographic landscape while preserving privacy.

This visibility gap becomes increasingly significant as the quantum threat landscape evolves.

“You can’t migrate what you can’t see. Visibility is the first mile of every quantum-safe journey.”

Continuous visibility allows organizations to move beyond periodic assessments and maintain a real-time understanding of cryptographic risk. This helps security teams identify weak or deprecated algorithms, uncover undocumented cryptographic dependencies, monitor certificate health, and measure crypto-agility as part of their PQC transition strategy. As part of its broader cyber resilience portfolio, Infosys Cyber Next integrates cryptographic visibility capabilities powered by Venari Security, enabling enterprises to assess quantum readiness based on observed cryptographic activity across their environments rather than relying solely on static inventories or assumptions.

With PQC emerging as a strategic business imperative, continuous cryptographic visibility transforms quantum preparedness from a one-time assessment into an ongoing risk management discipline. It empowers organizations to prioritize remediation efforts, measure progress, and make informed decisions on their journey toward a quantum-safe future.
