Who is PQShield?
PQShield is a cryptography company focused on quantum-safe security solutions for hardware, software, and communications systems.
- Post-Quantum Cryptography (PQC) IP cores and firmware for hardware vendors (security IP / semiconductor enablement).
- Software libraries implementing quantum-safe cryptography for servers, applications, and connected devices (application security).
- Protocols and toolkits to secure data in transit and at rest against quantum-capable adversaries (network and data security).
- Advisory and integration support for migrating enterprises and public-sector organizations to post-quantum cryptographic schemes (security consulting).
- Compliance-aligned implementations of NIST and Internet Engineering Task Force (IETF) post-quantum standards for use across embedded, cloud, and mobile environments (standards-based security).

More About PQShield
PQShield focuses on PQC, providing hardware, software, and protocol-level solutions designed to protect data and systems against attacks from both classical and quantum computers. Its offerings target organizations that need to align with emerging post-quantum standards and to address long-term confidentiality requirements, such as enterprises handling regulated data, manufacturers of secure hardware, and government or public-sector institutions.
The company’s hardware-focused portfolio (security IP) centers on cryptographic intellectual property blocks and firmware that can be integrated into silicon designs, secure elements, and chips used in devices such as smartcards, Internet of Things (IoT) modules, and secure enclaves. These IP cores implement standardized post-quantum algorithms and are designed to work alongside existing cryptographic primitives so that chipmakers and OEMs can support hybrid or migration architectures without redesigning entire platforms.
On the software side (application security), PQShield provides cryptographic libraries for servers, cloud-native workloads, mobile applications, and embedded software. These libraries expose APIs for post-quantum key establishment, digital signatures, and other core cryptographic functions, aligning with algorithms selected or standardized by bodies such as NIST for PQC. The software is positioned to enable developers and security teams to adopt quantum-safe schemes in applications, VPNs, messaging systems, and identity or Public Key Infrastructure (PKI) infrastructures.
PQShield also addresses protocols and system architectures for data in transit and at rest (network and data security). Its work aligns with post-quantum extensions in protocols such as Transport Layer Security (TLS) and other IETF initiatives related to hybrid key exchange and quantum-safe communication. This supports deployment in environments like secure web services, Machine-to-Machine Communication (M2M), and enterprise networks where forward secrecy and long-duration confidentiality windows are required.
In addition, the company offers advisory and integration services (security consulting) that help organizations plan and execute a migration path from classical public-key schemes to post-quantum alternatives. This includes assessing cryptographic inventories, designing hybrid cryptographic architectures that combine classical and post-quantum algorithms, and validating implementations against relevant standards and guidance from standardization bodies.
Within an enterprise technology directory, PQShield aligns with categories such as cryptographic IP for semiconductors, application-layer cryptography libraries, quantum-safe network security, and post-quantum migration consulting services. Its solutions are positioned for use by semiconductor vendors, OEMs, cloud and infrastructure providers, and security-conscious enterprises that require standards-based, quantum-resistant cryptographic building blocks integrated into their hardware, software, and communication stacks.
