What Is a PKI Software?
Public Key Infrastructure (PKI) software forms the backbone of secure digital communication, providing a framework for creating, distributing, managing, and revoking digital certificates. These certificates validate the identity of individuals, systems, or devices on a network, ensuring only authorized parties can access sensitive information.
Whether you are working on-premises or in the cloud, such software automates the provisioning and validation of digital certificates, significantly reducing the vulnerabilities associated with manual certificate management. By utilizing a solution like AWS Certificate Manager or any of the other PKI management tools, you can rest assured that your certs are handled securely, mitigating risks such as downtime and outages.
They can efficiently address workload-specific needs and tackle potential crypto-related issues. Cloud-based PKI tools, in particular, offer a level of convenience and flexibility, eliminating the hassles of traditional on-premises IAM management.
