Who it fits
CNSA 2.0-aligned, hardware-rooted protection is offered for systems already in service, through the contract vehicles customers use. Federal, state and local procurement is available through GSA and SLED contract paths, alongside the reseller and integrator ecosystem. PQC+™ is offered as a drop-in for HPE ProLiant and other servers, bought through the channels customers already use. The offer covers strengthening what is running today, with cryptography updated later without new hardware.From its own pages, the company directs QuProtect at commercial and federal channel partners. The stated aim is to let those partners secure their networks, communication, and data. The site also carries industry pages for financial services, insurance, energy and grid, hospital systems, manufacturing, pharma and life sciences, and state and local government.

Where they overlap

  • Post-quantum cryptography is the primary category of both EigenQ and QuSecure; both are also filed under Encryption, tokenization and key management.

Where they differ, field by field

  • EigenQ is also filed under Firmware and device supply chain security and Machine identity and PKI.
  • EigenQ lists PQC+™. QuSecure lists QuProtect R3, QuProtect and QuEverywhere.
  • QuSecure is headquartered in San Mateo, United States.
  • QuSecure is privately held.

How they differ

CISO Tribune files both EigenQ and QuSecure under Post-quantum cryptography as the primary category, and both also appear under Encryption, tokenization and key management. EigenQ sells PQC+™, a PCIe or M.2 card that adds hybrid post-quantum cryptography, quantum-generated entropy, hardware-rooted device identity and crypto agility to servers already in use. QuSecure sells software instead: QuProtect R3 is a platform for cryptographic command and control, and QuProtect protects encrypted communications and data. QuSecure also sells QuEverywhere, which orchestrates quantum-safe cryptography for websites and mobile applications.

EigenQ is also filed under Firmware and device supply chain security and Machine identity and PKI, which fits its hardware-rooted identity and attestation that confirm a device before it joins. QuProtect R3 delivers continuous cryptographic inventory, remediation to TLS 1.3 with ML-KEM, automated certificate rotation, and compliance evidence, and it operates across cloud, on-premises, air-gapped, and sovereign environments. EigenQ offers PQC+™ as a drop-in for HPE ProLiant and other servers, with federal, state and local procurement available through GSA and SLED contract paths. QuSecure directs QuProtect at commercial and federal channel partners.

QuSecure is headquartered in San Mateo, United States, and is privately held. On July 6, 2026, EigenQ announced platform capabilities for preparing deployed Intel Xeon processor-based systems for CNSA 2.0-aligned post-quantum migration requirements. On September 22, 2026, QuSecure announced it was named a Cool Vendor in a Gartner report on data security innovations.

What it sells: QuSecure

What QuProtect R3 does[7][9][10]
QuProtect R3 delivers continuous cryptographic inventory, remediation to TLS 1.3 with ML-KEM, automated certificate rotation, and compliance evidence. QuProtect R3 enables security teams to swap algorithms and push cryptographic policy changes across their entire network from one place. QuProtect R3 operates across cloud, on-premises, air-gapped, and sovereign environments and is backwards compatible with legacy infrastructure.
What QuProtect does[1][3][4][7][9][10][11][12][13]

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]
