Forescout Enhances PQC Visibility for IT, OT, IoT, and IoMT Security

Post Views: 1

Forescout has unveiled new dashboards focused on Post-Quantum Cryptography (PQC) readiness and encryption hygiene, designed to help organizations evaluate and manage quantum risks across IT, operational technology (OT), Internet of Things (IoT), and medical devices (IoMT).

Quantum Risks Remain Widespread

Quantum risks remain widespread, according to Forescout Research data from Vedere Labs. The findings reveal that nearly 90% of SSH servers globally lack quantum-safe configurations, while enterprise environments show uneven adoption rates. Among IT devices, 50% support PQC-capable SSH protocols, but this drops to 28% for IoT devices, 16% for OT systems, and 6% for IoMT equipment.

Key Features of the PQC Dashboards

The PQC readiness and encryption hygiene dashboards offer continuous monitoring of cryptographic postures across complex environments. Key features include:

Quantum Encryption Assessment: A unified view of cryptographic health, including quantum-safe scores, asset coverage, and PQC adoption rates.
Weak Encryption Mapping: Identification of assets with insecure encryption, linking protocol usage to their operational significance.
Protocol Risk Analysis: Differentiation between immediate hygiene issues and long-term PQC risks.
Traffic Encryption Analysis: Detection of concentrations of non-quantum-safe traffic across networks.
Risk Correlation: Linking encryption vulnerabilities to active threats and external exposure.

Shifting PQC to Operational Security

By integrating these capabilities, Forescout shifts PQC from a compliance-focused task to an operational security practice. The tools enable organizations to move beyond mere discovery, focusing instead on prioritizing actions based on real-world impact. Security teams can assess asset criticality, exposure levels, and environmental context to allocate resources effectively.

Industry Leaders Emphasize Early Preparation

Industry leaders stress the importance of early preparation. Paul Kao, Forescout’s Chief Product Officer, noted that enterprises must demonstrate awareness and governance of PQC long before large-scale migrations become feasible. Regulatory frameworks, including guidelines from the Group of Seven (G7) and the U.S. National Institute of Standards and Technology (NIST), highlight inventorying and risk assessment as foundational steps.

Forescout’s tools enable organizations to meet these expectations years ahead of full PQC implementation. The launch aligns with global efforts to address quantum threats, particularly in environments where unmanaged or hard-to-upgrade assets pose the highest risks.

Proactive Approach to Quantum Security

The tools reflect a growing industry recognition that quantum security requires continuous monitoring, not one-time fixes. Organizations leveraging the dashboards gain a dynamic view of their quantum risk landscape, translating visibility into targeted mitigation strategies. This proactive approach ensures that security teams can adapt to evolving threats while adhering to regulatory mandates.
