Why PKI managed services matter

Operating Public Key Infrastructure demands specialist expertise, continuous monitoring, and strict adherence to security and regulatory standards. Many organisations lack the internal resources, skills, or technology to maintain PKI systems effectively, leading to risks around availability, compliance gaps, and operational inefficiency.

Poorly managed PKI environments create vulnerabilities. Certificate outages disrupt business operations and services, whilst inadequate governance exposes organisations to audit findings and regulatory compliance failures. As digital transformation accelerates and certificate volumes increase, the operational burden grows alongside the complexity of maintaining supporting infrastructure, hardware security modules, and secure key management practices. To understand why robust PKI is fundamental to maintaining digital trust in this landscape, see further insights here.

A managed PKI service provides expert oversight, proactive monitoring, and automated processes that reduce risks whilst freeing internal teams to focus on strategic priorities and business roadmap initiatives. You retain control and visibility over your certificate estate, whilst we handle the day-to-day operations and ensure your PKI remains secure, compliant, and aligned with industry best practices.

Enterprise organisations require resilience, trust, and assurance that their cryptographic infrastructure will support digital transformation without compromising security. Our managed services address these needs whilst enabling organisations to maintain policy enforcement and meet regulatory requirements.

What we do

PKI is complex, resource-heavy, and mission-critical. Unsung specialises in taking the burden off your internal teams by delivering fully managed, secure Public Key Infrastructure services tailored to your organisation's needs.

With decades of experience and deep technical knowledge, we support multiple Certificate Authority platforms and certificate lifecycle management tools across on-premise, hybrid, or cloud environments. We're vendor-agnostic, and our managed service model offers centralised oversight whilst maintaining your control over systems and procedures.

Our managed services are trusted by government and private sector clients, including mission-critical defence and national infrastructure projects. We ensure security, business continuity, and compliance across your PKI estate whilst maintaining transparency and visibility throughout service delivery.

How we help

Unsung provides a complete PKI Managed Service that handles everything from day-to-day operations and system monitoring to updates, incident response, and governance. We operate and host PKI platforms, ensure certificate availability, maintain compliance, and support your business continuity goals.

With options for centralised, cloud-hosted management and automation of certificate lifecycle management processes, we give you the oversight and transparency you need without the operational overhead. You retain control of your certificate estate whilst we ensure it stays secure, available, and aligned with policy and business priorities.

PKI operations and monitoring

We run your Public Key Infrastructure, managing routine operations including certificate issuance, revocation, renewal, system patching, and performance monitoring. Our enterprise-grade support ensures your systems remain available and secure. We implement industry best practices for key management, protect key material through hardware security modules, and maintain supporting infrastructure to ensure resilience. Our procedures cover end-to-end operations, from certificate lifecycle management through to incident response and communication with stakeholders.

Hosted PKI solutions

We provide secure hosting for your PKI components, whether that's full cloud, hybrid, or on-premise deployment. Our hosted solutions ensure availability, scalability, and resilience whilst maintaining security standards and regulatory compliance. We design and implement infrastructure that meets your security requirements whilst supporting business growth and digital transformation initiatives. Our hosting services include secure facilities, redundant systems, and proven technology stacks.

Certificate lifecycle management and automation

We automate certificate issuance, renewal, and expiry processes, reducing risks and saving your organisation time and resources. Our certificate lifecycle management practices ensure certificates are tracked, monitored, and renewed before expiration. Automation eliminates manual procedures, reduces human error, and ensures consistent policy enforcement across your certificate estate. Our CLM tools provide visibility into certificate status, expiry dates, and compliance posture.

Hardware security modules and key management

We manage hardware security modules that protect cryptographic key material, ensuring secure key generation, storage, and usage. Our expertise covers HSM integration, key ceremony procedures, and secure key lifecycle management aligned with industry best practices and regulatory requirements. We maintain supporting infrastructure for HSMs and implement controls that ensure compliance with security standards including Cyber Essentials and ISO frameworks.

Governance and compliance

We manage documentation, logs, audits, and compliance reporting, aligning with regulatory standards and your internal policies. Our governance framework ensures transparency, supports ISO certification requirements, and provides the audit trail needed for regulatory compliance. We maintain visibility across your PKI estate and provide regular updates on security posture and compliance status. Our approach ensures your organisation can demonstrate adherence to industry best practices and meet obligations under relevant regulatory frameworks.

Flexible control models and partnerships

Our managed services are built to flex, allowing you to retain oversight, decision-making rights, and visibility whilst we handle operations. We collaborate with your teams, share lessons learned, and provide training to build internal skills and capability. Our willingness to adapt our service delivery ensures the partnership works for your organisation's needs and risk tolerance. We work closely with clients to understand opportunities for improvement, support transition to new technology, and enable longer-term resilience across your cryptographic infrastructure.
