What Unsung does
Unsung is a London-based specialist consultancy focused exclusively on Public Key Infrastructure (PKI), encryption, authentication, and identity services. Founded in 2009 and registered in England and Wales, the firm positions itself as a vendor-neutral, PKI-only practice, concentrating expertise across the full cryptographic lifecycle rather than competing in broader cybersecurity. Service lines comprise PKI Consultancy, PKI Design & Build, PKI Health Check, Certificate Lifecycle Management, PKI Management & Hosting, Hardware Security Modules, and a Cryptographic Bill of Materials (CBOM) offering that provides organisational cryptographic-asset inventory and post-quantum readiness assessment. The consultancy is differentiated by SC/DV security-cleared consultants, supply on UK Government G-Cloud, Digital Outcomes 6, and Cyber Security Services 3 frameworks, and ISO 27001 plus Cyber Essentials Plus certifications, giving it access to defence and central-government procurements. Named enterprise customers include Rolls-Royce, ASML, Sykehuspartner, and Sopra Steria, served across defence, central government, financial services, healthcare, transport, and nuclear verticals.
The business operates a service-led, hybrid revenue model combining professional-services engagements (fixed-price and time-and-materials PKI consultancy), managed-services revenue (24/7 PKI management and hosting), and an emerging productised layer via the Certdog Gold Partnership with Krestfield, which Unsung resells and implements as a Certificate Authority and CLM platform with REST API, PowerShell, .NET, and Java clients, and ACME/EST/CMP/SCEP protocol support. Pricing is quote-based under multi-year and pay-as-you-go cadences; specific price points are not publicly disclosed. Distribution is direct enterprise sales via website contact, telephone, and email, with no channel-reseller motion. Recent strategic activity has concentrated on an ecosystem buildout around post-quantum cryptography: a 2026 cluster of partnerships with Crypto4A (quantum-safe HSMs), Krestfield/Certdog (CLM for AD CS environments), and Cryptomathic (enterprise key management via CrystalKey 360) signals intent to capture wallet share across the full PQC migration cycle. The firm has no disclosed funding history, no parent, and no public-listing trajectory; ownership and control are not disclosed in available sources.

Unsung product offering
Product offeringCore offering
Unsung is a specialist PKI consultancy delivering expert cryptographic services across the full PKI lifecycle, including PKI Consultancy, PKI Health Check, PKI Design & Build, Certificate Lifecycle Management, PKI Management & Hosting, Hardware Security Module integration, and Cryptographic Bill of Materials (CBOM) assessments. The company also resells and implements the Certdog CA/CLM platform as a Certdog Gold Partner, serving government, defence, financial services, healthcare, transport, and nuclear sectors via SC/DV cleared consultants.
Product overview
Unsung is a specialist PKI consultancy delivering a portfolio of cryptographic services rather than a single software product. The core offering spans seven service lines: PKI Consultancy, PKI Health Check, PKI Design & Build, Certificate Lifecycle Management, PKI Management & Hosting, Hardware Security Modules, and Cryptographic Bill of Materials (CBOM). Additionally, Unsung operates as a Certdog Gold Partner and Value-Added Solutions Provider, reselling and implementing the Certdog CA/CLM platform—a UK-developed Certificate Authority and lifecycle management platform that provides the technical layer for automated discovery, issuance, renewal, and revocation. Certdog integrates directly with existing Microsoft AD CS environments and external CAs, acting as the management and automation layer for organisations that have outgrown native tooling. The service portfolio and Certdog product work together: consultancy services assess and design PKI architecture, CBOM provides cryptographic inventory visibility, and Certdog delivers the automated lifecycle management platform.

Unsung competitors and assessment
Company assessmentDirect peers
- Entrust: Entrust is a PKI and digital identity vendor offering its own CA, HSM, and CLM stack (PKI Hub). It is both a Unsung partner and a competitor, with overlapping enterprise/government PKI delivery teams.
- DigiCert: DigiCert is the largest public CA and an enterprise PKI/CLM platform provider (Trust Lifecycle Manager). A direct competitor for enterprise PKI modernization work while also a vendor partner to Unsung.
- Sectigo: Sectigo is a PKI and certificate lifecycle vendor (including its CLM platform) competing in the same enterprise/government PKI infrastructure space Unsung serves.
- Venafi (DigiCert Machine Trust Manager): Venafi is a leading machine identity and CLM platform that competes directly in the certificate lifecycle management and PKI operational tooling space that Unsung designs and deploys around Certdog and Keyfactor.
- Encryption Consulting: Encryption Consulting is a specialist PKI, HSM, and certificate lifecycle management consultancy offering advisory, implementation, and managed services. Closest direct analogue to Unsung in business model, vendor-neutral stance, and focus on enterprise/government PKI modernization.
- Trustis: Trustis is a UK-based specialist PKI, identity, and cryptography consultancy serving government and regulated industries — a closely comparable regional specialist peer to Unsung in the UK public sector market.
- Keyfactor: Keyfactor is a PKI and CLM platform vendor (EJBCA, Keyfactor Command) that also delivers professional services. Direct competitor in PKI advisory and to Unsung's Certdog positioning, while simultaneously being a partner.
- GlobalSign: GlobalSign is a public CA and enterprise PKI/identity solutions provider, comparable to Unsung's CA-focused engagements and Certdog-style internal CA offerings.
Emerging players
- Ascertia: Ascertia is a UK-headquartered digital trust, PKI, and e-signature vendor with adjacent cryptographic services. A minor partner of Unsung that operates in overlapping enterprise/government trust services territory.
