What is Certificate Lifecycle Management (CLM)?

Certificate Lifecycle Management (CLM) serves as a critical cybersecurity process that manages the discovery, issuance, storage, deployment, revocation, and renewal of digital certificates. These processes ensure secure communications between devices and servers on the internet. CLM keeps digital certificates, predominantly in the X.509 format, current and correctly configured throughout their lifecycle, allowing machines and sometimes humans to authenticate each other and securely exchange information over the internet. CLM also avoid outages due to the expiration of certificates. This safeguard helps prevent security breaches and maintain operational integrity.

The Importance of CLM in Cybersecurity

Digital certificates, acting as digital IDs, authenticate and secure digital interactions. Efficiently managing these certificates through CLM is essential for:

1. Keeping certificates current and correctly configured: Maintaining current and correctly configured certificates is a fundamental requirement for operational integrity. When certificates are left to expire, they frequently cause application outages, a common problem in manual management systems. These outages can disrupt uninterrupted operations, including the functionality of broken APIs and other digital services. Furthermore, having a centralized repository with full observability into the health status of certificates is essential for security audits and compliance. As the industry moves toward shorter validity periods; such as the proposal to reduce public SSL/TLS certificate lifespans to 90 days; automated Certificate Lifecycle Management (CLM) becomes vital to adapt and prevent the risks associated with manual errors.
2. Preventing unauthorized access and data breaches: Unmanaged or compromised certificates significantly increase an organization’s vulnerability to security breaches. Regular rotation, the process of periodically replacing certificates before they expire or become compromised, is a crucial security measure to prevent unauthorized access. By automating the discovery, rotation, and revocation of certificates, organizations can proactively avoid hacks and ensure that only authenticated entities can interact with their systems. Without these automated protections and notifications, certificates can become a weak point that allows for unauthorized entry and potential data breaches
3. Facilitating trusted digital communications and transactions: Digital certificates serve as digital IDs that are foundational to establishing trust across the internet. They allow machines and humans to authenticate each other, ensuring that information is exchanged securely between devices, servers, and users. A certificate management system supports trusted communications and transactions by overseeing the entire lifecycle, from issuance to renewal, across various endpoints like Linux, Windows, and Kubernetes. This rigorous management ensures continuous trust across applications, users, APIs, and services, allowing for the secure and reliable exchange of information in a digital-first environment

Key Components of Certificate Lifecycle Management

Automated Renewal Process:

Streamlining certificate renewal with automatic CSR and key generation prevents business disruptions. Automated renewal mitigates the risk of service outages caused by missed renewal deadlines—a critical vulnerability since expired certificates immediately break HTTPS connections and prevent users from accessing services.

Secured Storage:

Maintaining a centralized certificate repository provides essential visibility into the health and lifecycle status of every certificate. This approach mitigates compliance gaps and audit risks by ensuring all certificates are discoverable, accounted for, and properly tracked during security reviews and regulatory assessments.

Notification of Certificate Expiration:

Automated expiration alerts enable proactive certificate management by notifying teams weeks in advance of renewal deadlines. This advance warning mitigates the risk of service downtime and weakened security posture—expired certificates enable man-in-the-middle (MITM) attacks because they no longer establish trusted encryption, making systems vulnerable to attackers.

Certificate Provisioning:

Automated deployment and replacement of certificates across Linux, Windows, and Kubernetes environments reduces human error and configuration mistakes. This automation mitigates configuration errors and operational burden on IT teams, ensuring certificates are consistently deployed across hybrid and multi-cloud infrastructure without manual intervention.

Private CA and PKI as a Service:

Establishing a private Certificate Authority gives your organization direct control over certificate issuance and trust relationships. This approach mitigates unauthorized access risks by enabling strong internal trust verification and eliminating dependency on external CAs for internal communications while maintaining full transparency and control.

Public CA Integration:

Integrating with major public Certificate Authorities through a unified platform enables efficient management of external-facing certificates. This capability is essential for managing compliance with evolving CA/Browser Forum standards—including the current requirement for certificates to have a maximum validity period of 47 days by 2029, which necessitates high-frequency automation to maintain service continuity.

Certificate Discovery:

Automated discovery identifies all existing certificates within your network, preventing forgotten or “shadow” certificates from creating blind spots. This mitigates unexpected outages caused by overlooked certificate expirations and security breaches by ensuring every certificate is visible, tracked, and managed under centralized security policies.

The Akeyless Platform delivers all of the components above. Upcoming enhancements are being added for ACME Standard integration, improving the versatility of certificate management and the integration with Let’s Encrypt, DigiCert and Sectigo.

Google’s 90-Day TLS Certificate Mandate

Google’s proposal to reduce the validity period for all public SSL/TLS certificates to 90 days from 398 days will impact a broad range of businesses using SSL/TLS certificates to secure their websites, not just those using Google Cloud. This policy change requires adaptations across websites and certificate protocols, affecting certificate authorities and businesses across various domains. It’s part of a move to improve security procedures and promote automation, with the implementation likely to occur in 2024.
