# Best Certificate Lifecycle Management (CLM) Software - Page 2

  *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)

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.

### 17. [AlertaCert](https://www.g2.com/products/alertacert/reviews)
  AlertaCert is a certificate lifecycle management (CLM) solution that helps accounting firms and tax professionals in Latin America automate the monitoring, storage, and renewal of government-issued digital certificates. The platform functions as a security-first repository designed to eliminate the operational risks associated with the silent expiration of credentials required for tax filings and legal compliance. In the regulatory environments of Mexico, Colombia, Argentina, and Brazil, tax authorities do not typically provide proactive notifications for certificate expiry. This creates a significant liability for firms managing portfolios for hundreds of clients, as a single expired certificate can lead to missed deadlines and financial penalties. AlertaCert centralizes these credentials within an encrypted environment to provide oversight and automated administrative support. The platform includes a set of specialized features tailored to the workflows of modern tax professionals: - Multi-Channel Automated Alerts: The system delivers proactive expiry notifications via WhatsApp and email at designated intervals of 90, 60, 30, 15, and 7 days before a certificate becomes invalid. - Secure Encrypted Vaulting: All digital certificates, including e.firma (SAT), CSD, DIAN, AFIP, and e-CNPJ, are stored using AES-256-GCM encryption standards to ensure data integrity. - Real-Time Status Validation: Users can verify the current standing of certificates against official government databases to confirm they have not been revoked or compromised. - PDF Multi-Signature Workflows: The software includes a proprietary signing module that allows firms to send documents for digital signature; external signers are not required to create an account to complete the process. - White-Label Customization: Firms can configure outgoing WhatsApp messages and emails to reflect their own branding, ensuring a professional and consistent experience for their clients. By supporting the regulatory ecosystems of multiple jurisdictions including Italy and India, AlertaCert enables firms to scale their operations without increasing administrative overhead. The centralized dashboard provides filtering and search capabilities that allow for the management of 10 to 500+ client accounts from a single interface. This structured approach to certificate management assists firms in maintaining compliance and protecting client relationships through automated technical safeguards.

### 20. [CertKit Certificate Lifecycle Management](https://www.g2.com/products/certkit-certificate-lifecycle-management/reviews)
  CertKit is a certificate lifecycle management platform that automates SSL/TLS certificate discovery, renewal, and deployment across diverse infrastructure environments. The solution addresses the operational challenges of managing certificates as validity periods shorten from the current 398 days to an anticipated 47-day maximum. Organizations with 10 or more servers face increasing certificate management overhead as manual processes become unsustainable with shorter certificate lifespans. CertKit provides centralized management without creating a single point of failure, automatically discovering existing certificates across infrastructure and handling renewal workflows before expiration events occur. The platform integrates with ACME protocol providers including Let's Encrypt, supports DNS-based validation through secure proxy mechanisms, and deploys renewed certificates to target systems automatically. DevOps engineers, system administrators, and IT operations teams use CertKit to eliminate manual certificate management tasks that consume hours of technical staff time. The platform monitors certificate status across Linux, Windows, Kubernetes, and cloud environments, providing unified visibility into certificate inventory regardless of where certificates are deployed. Unlike command-line tools that require extensive scripting for multi-server environments or enterprise PKI suites that demand specialized expertise, CertKit offers accessible certificate management through both web interface and API access. Key capabilities include: - Automated Discovery: Identifies certificates across infrastructure including forgotten systems, preventing surprise expirations from legacy servers or development environments - Multi-Channel Alerting: Delivers expiration warnings and status updates through email, Slack, Microsoft Teams, and other communication platforms teams actively monitor - DNS Validation Proxy: Handles wildcard certificate validation without requiring full DNS API access, limiting permissions to TXT record modifications only - Deployment Automation: Pushes renewed certificates to target systems automatically, eliminating manual distribution across server farms - Role-Based Access Control: Enables teams to delegate certificate management tasks without exposing critical infrastructure credentials The platform operates outside the critical path, meaning certificate-protected services continue functioning even during CertKit maintenance windows. This architecture provides reliability advantages over distributed renewal scripts that fail silently on individual servers.

### 25. [EZRADIUS](https://www.g2.com/products/ezradius/reviews)
  EZRADIUS by Keytos is a cloud RADIUS service that helps IT and security teams authenticate users and devices on Wi-Fi, VPN, and wired networks without running on-premises RADIUS infrastructure. Built by ex-Microsoft engineers, it is designed to replace Microsoft NPS, FreeRADIUS, and other legacy RADIUS servers with a fully managed, cloud-native service that integrates natively with Microsoft Entra ID and Intune. Organizations use EZRADIUS to move from password-based network authentication to certificate-based, passwordless access, supporting Zero Trust initiatives, PCI DSS and HIPAA compliance programs, and the retirement of legacy on-premises authentication servers. EZRADIUS supports passwordless, certificate-based authentication via EAP-TLS, along with MSCHAP-v2, EAP-TTLS, PEAP, and MAC Authentication Bypass (MAB). It integrates natively with Microsoft Entra ID and Intune, allowing device compliance and group-membership checks to be enforced at authentication time. Both Classic RADIUS and RadSec (RADIUS over TLS) are supported, with dynamic IP options for distributed and remote sites. EZRADIUS works with any existing PKI or pairs with EZCA, Keytos's cloud certificate authority, for end-to-end passwordless deployment. Audit logs, dashboards, and log streaming to existing SIEM or Azure Log Analytics workspaces are included, and the service is available through the Azure Marketplace with MACC-eligible billing or directly through Keytos with a free trial. Common use cases include WPA2-Enterprise and WPA3-Enterprise Wi-Fi authentication for corporate and guest networks, BYOD certificate enrollment and Wi-Fi profile distribution for non-managed devices, segmented network access for IoT and point-of-sale (POS) devices, VPN authentication, Zero Trust Network Access (ZTNA) rollouts, and migration from Microsoft NPS, FreeRADIUS, and other legacy on-premises RADIUS deployments. EZRADIUS is typically deployed in hours rather than the weeks or months required for on-premises RADIUS, with video tutorials and guides for all the most popular network vendors, including Cisco Meraki, UniFi, Ruckus, and Fortinet. Customers pay only for the identities that authenticate each month and can scale from 10 to 10,000+ identities without changing their configuration.
