# Best Certificate Lifecycle Management (CLM) Software - Page 3 *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)* Certificate lifecycle management (CLM) and PKI software help companies with the process of authenticating and encrypting information using digital certificates. Public key infrastructure (PKI) is a cryptography framework that secures digital communication and protects data, devices, machines, and people from impersonation, unauthorized interception, tampering, or other attacks. The main benefit of this software is that it provides visibility and automation throughout the certificate lifecycle—certificate issuance, discovery, inventory, provisioning, deployment, securing, monitoring, renewal, and revocation. CLM and PKI software often replaces manual certificate management methods, such as tracking on spreadsheets, which helps companies prevent unplanned system downtime and system vulnerabilities stemming from errors or certificate expiration. CLM and PKI software provide capabilities for the issuance, management, and automation of digital certificates, including but not limited to [SSL & TLS certificates](https://www.g2.com/categories/ssl-tls-certificates), client authentication certificates, digital signature, and SSH certificates. Use cases for PKI and CLM software include user authentication, machine-to-machine authentication for servers and containers, digitally signing code and documents, encryption and integrity for IoT devices, and much more. To qualify for inclusion in the Certificate Lifecycle Management (CLM) and PKI category, a product must: - Automate CLM, including discovery, inventory, provisioning, deployment, securing, monitoring, renewal, and revocation (some vendors will offer certificate issuance solutions via public certificate authority or private PKI functionality) - Provide centralized visibility, control of, and reporting on certificates, keys, and ciphers - Monitor and notify administrators when certificate expiration dates are nearing or use workflow to automatically take a specified action, such as certificate renewal or revocation - Support certificates from multiple certificate authorities (CAs) ## How Many Certificate Lifecycle Management (CLM) Software Products Does G2 Track? **Total Products under this Category:** 75 ### Category Stats (Jul 2026) - **Average Rating**: 4.4/5 (↑0.02 vs Jun 2026) The average rating of products in this category, based on all submitted ratings - **Top Trending Product**: Keyfactor Command (+0.16%) - Among all products in this category, Keyfactor Command recorded the largest rating increase compared to last month *Last updated: July 03, 2026* ## How Does G2 Rank Certificate Lifecycle Management (CLM) Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 1,700+ Authentic Reviews - 75+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts.

This platform combines Dynamic Public Key Infrastructure (PKI) and Cloud RADIUS to facilitate real-time trust validation and continuous authentication for users accessing networks and applications. Each access request initiates an identity-based risk assessment, which determines the issuance of certificates and the corresponding access privileges. Once access is granted, the system continuously validates the compliance of devices, ensuring that only verified entities maintain their authorization. The JoinNow Platform caters to a diverse range of users, including K-12 and higher education institutions, mid-market businesses, and global enterprises. By providing scalable and resilient authentication solutions, SecureW2 addresses the unique security needs of various sectors without placing an additional burden on IT teams. The platform's ability to seamlessly integrate with existing identity providers, such as Entra ID (formerly Azure AD), Okta, and Google Workspace, allows organizations to implement adaptive, passwordless authentication without the need for complex upgrades or disruptions. SecureW2 effectively tackles several prevalent security challenges. Credential compromise remains a significant concern, as traditional passwords and multi-factor authentication (MFA) can be vulnerable. By utilizing certificate-based authentication, SecureW2 eliminates these risks entirely. Additionally, the platform addresses high operational overhead associated with managing legacy security systems by automating certificate issuance, revocation, and lifecycle management. This automation not only saves IT resources but also enhances visibility and control, providing real-time insights into authentication processes. Key features of SecureW2 include its agentless architecture, which eliminates software bloat while ensuring secure and frictionless authentication. The extensive policy engine allows organizations to create customized policies that are automatically enforced both before and after authentication. Continuous authentication adapts in real time, validating access dynamically based on evolving security conditions. Furthermore, the platform’s interoperability ensures compatibility with any identity provider, mobile device management (MDM) system, and security stack, making it a versatile choice for organizations looking to enhance their security posture. In summary, SecureW2 redefines authentication for modern businesses by ensuring that every access request is trust-validated. Its scalable, lightweight design enables rapid deployment and effortless scaling, allowing organizations to maintain robust security without the complexities and costs typically associated with traditional authentication solutions.
