About EigenQ

EigenQ sells PQC+™, which brings trust capabilities from entropy to identity to execution together in a hardware-anchored architecture. EigenQ is designed to establish trust at the foundational layers of computing.^[2]

Quantum computing and AI are changing the requirements for security, trust and communications. Organizations need to prepare for that transition without abandoning the technology, infrastructure and trusted relationships they depend on today. From January 1, 2027, new National Security System acquisitions must support CNSA 2.0.^[2]

PQC+™ is added to the servers customers already run, in PCIe or M.2. Hybrid post-quantum cryptography, quantum entropy, hardware-rooted trust and crypto agility are built into the servers and systems customers already run. Hardware-rooted identity and attestation confirm a device before it joins. ML-KEM and ML-DSA are NIST post-quantum algorithms. Quantum entropy provides stronger keys, and crypto agility allows algorithms to be updated.^[1]

PQC+™ is offered as a drop-in for HPE ProLiant and other servers, bought through the channels customers already use. EigenQ states that its post-quantum algorithms and quantum-entropy DRBG hold NIST Cryptographic Algorithm Validation Program certificates. Federal, state and local procurement is available through GSA and SLED contract paths, alongside the reseller and integrator ecosystem.

CNSA 2.0-aligned, hardware-rooted protection is offered for systems already in service, through the contract vehicles customers use. Hardware-backed keys, trusted identity and crypto agility are offered to protect transactions and customer data.

EigenQ brings together quantum research, cryptography, mathematics, algorithms, hardware and systems engineering. EigenQ combines technology development with an ecosystem-driven path to deployment. EigenQ starts with deployable quantum-ready security and trusted infrastructure today, while building toward broader capabilities across quantum communications, networking and computing.^[1][2]

Phosphorus Cybersecurity operates as Phosphorus, A Dragos Company. Phosphorus, a Dragos company, describes its product as an extended Security of Things platform designed to find, fix and monitor the often unmonitored Things of the enterprise xIoT environment. Phosphorus Cybersecurity is based in Nashville. Brian Contos is the chief security officer of Phosphorus Cybersecurity.^[2][3]

Phosphorus refers to the broader Internet of Things as the xIoT. Phosphorus describes such devices as purpose built IoT, OT and network devices running network-connected firmware, where endpoint security controls cannot be installed. Phosphorus research has focused on devices and technologies used by businesses and government, such as printers, voice over IP phones and physical access systems. A study of IoT device security by Phosphorus Labs found that 68% of the devices have high-risk or critical vulnerabilities. Phosphorus states that attackers exploit unmanaged, high-risk devices as entry points into critical operations. Phosphorus states that about 70% of xIoT devices still use default manufacturer credentials. Phosphorus states that about 68% of xIoT devices run vulnerable or outdated firmware. Phosphorus states that about one-quarter of xIoT devices are end-of-life.^[2][3][7][8]

Phosphorus discovers and profiles devices with contextual detail across a wide range of device attributes. Phosphorus identifies, classifies and prioritizes vulnerabilities across an xIoT estate. Phosphorus discovers and remotely disables devices prohibited under U.S.NDAA Section 889, including Huawei, Dahua, Hikvision, ZTE and Hytera devices and devices using their OEM firmware regardless of manufacturer.^[2]

Phosphorus automatically remediates xIoT device vulnerabilities, including credentials, firmware, certificates and risky configurations. Phosphorus manages and renews certificates across diverse device sets.^[2]

Phosphorus continuously monitors and manages xIoT devices and detects and responds to device drift. Phosphorus monitors xIoT estates to detect and alert on device drift and operational changes. Phosphorus provides centralized log collection and analytics for device-level security analysis, anomaly detection, triage and forensics.^[2]

Phosphorus integrates with ServiceNow to provide an automated framework for visibility and control. Phosphorus integrates with password management solutions such as CyberArk for automated xIoT credential management. Phosphorus integrates with Axonius to provide a view of xIoT asset details. Phosphorus integrates with Microsoft Sentinel to provide device enrichments and security insights.^[2]

Phosphorus Cybersecurity offers xIoT security for financial services. Phosphorus Cybersecurity secures IoT, OT and IoMT devices for healthcare security. Phosphorus Cybersecurity offers a unified xIoT security management platform for OT, ICS and IIoT cyber-physical systems. Phosphorus Cybersecurity offers end-to-end xIoT security for modern data centers.^[2]
