Public key infrastructure is rapidly expanding across cloud, IoT, digital signatures, and identity use cases, leading to more complex and distributed security environments. Organizations are increasingly adopting a mix of deployment models, including externally hosted private certificate authorities, public CAs, cloud-based private CAs, and partner or government-provided services. This diversification has improved flexibility but also introduced challenges such as limited visibility, skills gaps, and resource constraints. As PKI environments grow, managing and maintaining consistent security becomes more difficult, making it essential for organizations to modernize their approach and strengthen control over their cryptographic infrastructure.
