QuintessenceLabs Introduces TSF® Sentry Cryptographic Assessment and PQC Readiness Assessment at Quantum World Congress

New capabilities help

organisations move from continuous visibility to automated remediation, building a practical, risk-based path to post-quantum cryptography

CANBERRA, Australia, Sept. 23, 2026 /PRNewswire/ -- QuintessenceLabs, a leader in quantum-resilient cybersecurity, today announced the introduction of TSF^® Sentry Cryptographic Asset Management and its Post Quantum Cryptography (PQC) Readiness Assessment at Quantum World Congress, September 23–25 in College Park, MD.

Together, the new capabilities help organisations move from understanding their cryptographic exposure to taking action. TSF Sentry provides continuous cryptographic visibility across the enterprise, helping security teams identify where cryptography is being used, assess risk, and connect cryptographic findings to the applications and systems that need remediation. The PQC Readiness Assessment provides a structured, risk-based blueprint to help organisations prioritize their transition to post-quantum cryptography.

"Organisations cannot effectively plan their transition to post-quantum cryptography if they do not first understand where and how cryptography is being used across their environments," said Andreas Baumhof, Chief Technology Officer at QuintessenceLabs.

"But knowing where you stand doesn't make you quantum-safe – it just shows your vulnerabilities. TSF Sentry solves this by turning passive visibility into automated remediation. It doesn't just find the problems; it actively fixes them, giving security leaders a clear path to action. Combined with our PQC Readiness Assessment, this gives security leaders a clearer path from cryptographic visibility to action."

From cryptographic discovery to remediation

As organisations begin preparing for post-quantum cryptography, gaining an accurate view of their cryptographic environment is an essential first step. However, identifying cryptographic assets alone does not tell security teams which applications should be addressed first or how individual findings translate into remediation activities.

TSF Sentry is designed to provide continuous cryptographic inventory and actionable remediation guidance. By relating cryptographic findings to the applications performing cryptographic operations, TSF Sentry can relate individual cryptographic findings to the applications responsible for them, allowing organisations to address multiple findings through targeted application-level remediation. To support execution at scale, TSF Sentry exposes an API that integrates these remediation workflows seamlessly into the enterprise automation frameworks organizations already trust.

TSF Sentry turns cryptographic visibility into actionable remediation

Rather than leaving security teams with hundreds of individual cryptographic findings to investigate, TSF Sentry relates those findings to the applications performing cryptographic operations, helping organisations identify where remediation can have the greatest impact.

A risk-based approach to PQC readiness

The PQC Readiness Assessment complements this continuous visibility with a structured approach to planning. It helps organisations evaluate their current cryptographic posture, identify priorities based on business and security risk, and develop a practical roadmap for transitioning to post-quantum cryptography.

Rather than treating PQC migration as a single technology replacement exercise, the assessment helps organisations establish a prioritised plan aligned to their existing infrastructure, applications, data protection requirements, and organisational objectives.

"PQC readiness is ultimately about making informed decisions about where to start, what needs to change, and how to manage that change without disrupting the business," added Baumhof. "Our approach is designed to help organisations build crypto agility and address the highest-priority risks first, while working within their existing technology environments."

The new capabilities extend QuintessenceLabs' broader portfolio of quantum-resilient cybersecurity solutions, which is designed to help governments, defence organisations, critical infrastructure providers, and enterprises strengthen cryptographic resilience and prepare for evolving security requirements without disruptive rip-and-replace approaches.
