Overview
Unsung is a UK-based, vendor-neutral PKI consultancy with a team of over 20 specialist engineers serving government, defence, and enterprise clients. We provide professional services to help organisations design, implement, and manage Public Key Infrastructure across hybrid and cloud environments, including those built on AWS.
Our services include PKI health checks and assessments, certificate lifecycle management (CLM) implementation and optimisation, hardware security module (HSM) deployment and integration, PKI design and build for greenfield and migration programmes, and post-quantum cryptography readiness advisory. We work with leading platforms available on AWS Marketplace, including Keyfactor, to deliver fit-for-purpose trust architectures aligned to compliance frameworks such as ISO 27001, Cyber Essentials Plus, and NIST guidelines.
Engagements are scoped and priced through private offers. Whether you need an independent assessment of your existing PKI estate, support migrating to a cloud-native certificate authority, or guidance on preparing your cryptographic infrastructure for the post-quantum transition, Unsung provides hands-on expertise from initial discovery through to operational handover.
Highlights

Unsung focuses exclusively on Public Key Infrastructure, providing expert guidance on certificate lifecycle management, HSM deployment, and PKI architecture. We help organisations design, implement, and optimise trust infrastructure using leading platforms available on AWS Marketplace, including Keyfactor, ensuring your cryptographic environment is aligned to operational requirements and compliance frameworks.
- Proven delivery across high-assurance environments. Our team of over 20 PKI specialists has delivered health checks, design programmes, and managed services for UK central government, defence, healthcare, financial services, and critical national infrastructure clients. We hold ISO 27001 and Cyber Essentials Plus certifications and are listed on the UK Digital Outcomes and Specialists (DOS) framework.
- Post-quantum cryptography readiness. As cryptographic standards evolve in response to the quantum threat, Unsung helps organisations assess their exposure, build transition roadmaps, and prepare their PKI estates for NIST post-quantum algorithms. We provide practical, risk-led guidance that positions your infrastructure for long-term resilience without disrupting current operations.
