Unsung and Krestfield Announce Strategic Partnership to Deliver Certificate Lifecycle Management Solutions

Strategic partnership between Unsung and Krestfield to deliver Certdog certificate lifecycle automation for Microsoft AD CS and hybrid PKI environments.

Unsung is pleased to announce a strategic partnership with Krestfield, the developer of Certdog, a certificate authority and certificate lifecycle management platform designed to automate issuing and managing certificates across mixed PKI environments. This collaboration strengthens Unsung's ability to deliver comprehensive certificate management and automation services, particularly for organisations with existing Microsoft PKI investments.

Founded in the UK, Krestfield brings deep expertise in certificate management automation with their Certdog platform. Certdog provides a full certificate authority and lifecycle management system that can host its own CAs or integrate with existing CAs including Microsoft AD CS, with support for HSM and cloud key protection through AWS CloudHSM, Azure KeyVault and Google KMS. This aligns with Unsung's role as a trusted, vendor-neutral PKI partner, providing services from discovery and design through to managed services and post-quantum readiness planning.

This partnership strengthens our collective position in several key areas:

Certificate lifecycle management and automation

Certdog enables organisations to automate certificate issuance, renewal and revocation across their entire estate. Combined with Unsung's PKI expertise, clients gain complete visibility and control over their certificate infrastructure, reducing the risk of outages caused by expired certificates.

Microsoft AD CS integration

Certdog's particular strength in Microsoft AD CS environments makes it especially valuable for clients with existing Microsoft PKI investment. Organisations can achieve certificate visibility and automation without requiring complete platform replacement, delivering rapid value whilst maximising existing infrastructure investment.

Multi-vendor HSM and cloud support

Certdog supports multiple keystores and HSMs, including cloud-based options such as AWS CloudHSM, Azure KeyVault and Google KMS. This flexibility aligns with Unsung's vendor-neutral approach and supports organisations operating across hybrid and multi-cloud environments.

Discovery and monitoring

Certdog's TLS discovery scans and CRL/OCSP monitoring utilities help maintain PKI health across complex IT estates. Combined with Unsung's PKI health check services, organisations can identify vulnerabilities and compliance gaps before they become operational issues.

Darren Davies, CEO of Unsung, said:

"Our partnership with Krestfield reinforces our commitment to delivering practical certificate management solutions. Certdog's automation capabilities, particularly for Microsoft AD CS environments, enable us to help clients gain visibility and control over their certificate estate without disrupting existing infrastructure. This is exactly the kind of pragmatic approach our clients value."

As organisations face increasing complexity in managing certificates across hybrid environments, the need for automated, policy-driven certificate lifecycle management is critical. This partnership allows Unsung and Krestfield to support organisations in addressing these challenges, combining Certdog's automation platform with Unsung's deep PKI expertise and delivery capability.
