Unsung's PKI Certificate Lifecycle Management services help organisations automate certificate issuance, reduce operational risk, and maintain compliance. Our expert-led approach ensures business continuity through effective certificate governance and control.

Why PKI management matters

Expired certificates cause service disruptions that impact customers, partners, and internal operations. Without proper lifecycle management, organisations face increased complexity from unknown certificates, time-consuming manual processes, and insufficient governance over certificate issuance and revocation.

Public Key Infrastructure underpins digital security across your estate. Digital certificates enable authentication, encryption, and code signing, binding public keys to verified identities. The certificate management process ensures that PKI certificates remain valid and trusted throughout their lifecycle, whilst private keys require secure storage and protection. Effective certificate management provides visibility, ensures compliance, and supports security teams in maintaining control over public and private keys.

As organisations adopt cloud PKI solutions and support mobile devices, the certificate repository expands. Managing certificates across internal PKI environments and external certificate authorities demands automation, centralised platforms to manage certificate lifecycles, and clear policies that govern how certificates are issued, renewed, and revoked. A robust certificate management process is essential to maintaining trust and operational continuity.

Our certificate management approach

Certificate lifecycle management is fundamental to PKI health and operational reliability. Poorly managed digital certificates lead to service outages, security vulnerabilities, and compliance failures. Many organisations struggle with visibility across their certificate inventory, manual processes for certificate renewal, and inadequate monitoring of expired certificates.

Unsung provides consultancy and technical delivery for full-spectrum certificate management. We help organisations regain control of their PKI certificates, whether building new certificate management processes, optimising existing Public Key Infrastructure implementations, or responding to audit requirements.

Our approach is vendor-neutral. We work with the platforms and technology you choose, designing secure, compliant, and efficient Public Key Infrastructure PKI solutions tailored to your environment and business needs.

How we help with managing certificates

Assessment and advisory

We review your current certificate inventory, Public Key Infrastructure architecture, and certificate management processes. Our assessment identifies gaps in visibility, control, and efficiency. We evaluate how your organisation manages digital certificates and PKI certificates, including certificate renewal workflows, registration authority practices, and root certificate governance. We examine your certificate management process from request through to expiration, providing recommendations that address both immediate improvements and the resources needed to support future requirements.

Design and implementation for internal PKI and cloud PKI

We design and deploy certificate lifecycle management solutions aligned with your Public Key Infrastructure PKI architecture, security objectives, and compliance obligations. Our implementations establish clear certificate management processes for certificate issuance, renewal, revocation, and retirement. We integrate with certification authorities, configure certificate repositories, and implement secure storage for private keys and public keys. For Enterprise PKI environments, we ensure administrators can centrally manage PKI certificates whilst enabling appropriate self-service capabilities for users. We support both internal PKI architectures and cloud PKI deployments, ensuring seamless certificate management across hybrid environments.

Automation integration

We deploy and integrate automation solutions that manage the certificate management process from request through to expiration. Automation reduces time-consuming manual processes, eliminates human error, and ensures consistent application of certificate policy across your estate. We implement lifecycle automation that handles certificate provisioning, tracks validity periods, manages public key rotation, and handles revocation for compromised or deprecated PKI certificates.

Monitoring and alerting

We implement monitoring tools that track certificate status across your network, devices, and services. Our solutions provide visibility into PKI certificates issued by internal and external certificate authorities, identify unknown certificates, and alert on approaching expiration. Proactive monitoring ensures security teams can act before services are affected and relying parties maintain access to valid certificates with trusted public keys.

Certificate policy and crypto agility

We help you define and enforce certificate policies that align with regulatory standards and internal security governance. We establish controls for public certificates and security certificates, ensure crypto agility to support evolving cipher suites, and implement practices that protect corporate data. Clear policy frameworks support audit readiness and provide control over how PKI certificates are purchased, issued, and managed across the organisation. Our approach ensures your certificate management process meets compliance requirements whilst supporting operational efficiency.

Training and support

We provide training for security teams, administrators, and users, building internal capability to manage Public Key Infrastructure effectively. Our knowledge transfer covers certificate management best practices, the certificate management process from end to end, identity verification processes, and the use of centralised platforms. Ongoing expert support ensures your teams can maintain and continuously improve certificate lifecycle management, delivering long-term value and operational resilience.
