Best Certificate Lifecycle Management Software for Windows of 2025

ManageEngine Key Manager Plus, a web-based solution for key management, helps you to consolidate, control and manage SSH (Secure Shell), SSL (Secure Sockets Layer), and other certificates throughout their entire lifecycle. It gives administrators visibility into SSH and SSL environments, and helps them take control of their keys to prevent breaches and compliance issues. It can be difficult to manage a Secure Socket Layer environment when there are many SSL certificates from different vendors, each with a different validity period. SSL certificates that are not monitored and managed could expire or invalid certificates could be used. Both scenarios can lead to service outages or error messages, which could destroy customer confidence in data security. In extreme cases, this may even result in a security breach.

Business interruptions or system failures caused by expired or invalid digital certificates can be significant.
