Certificate management tools are essential for overseeing the lifecycle of digital security certificates, which include issuance, renewal, and revocation, especially in enterprises with numerous endpoints requiring bespoke setups. These tools manage certificate authorities (CAs) and ensure secure communication between applications, services, and devices by binding identities to public keys through digital certificates, typically following the X.509 standard. Effective certificate management prevents outages caused by expired certificates and aids in maintaining compliance with regulatory standards. Infisical is highlighted as a comprehensive solution that integrates certificate management with secrets management, offering features like centralized visibility, automated issuance, and the ability to handle multiple CAs, while also supporting ephemeral certificates for just-in-time access. Unlike traditional vendors, Infisical’s open-source foundation enhances transparency and adaptability, making it a vital tool in the evolving landscape of AI and enterprise security.
