# Supported Public Certifying Authorities CertiNext supports integration with leading **publicly trusted Certificate Authorities (CAs)** to enable centralized visibility and lifecycle management of internet-facing certificates across environments. **emSign** and **DigiCert** are natively available within CertiNext, allowing customers to manage publicly trusted certificates alongside private PKI through a single platform while retaining their existing CA relationships. Support for additional public CAs, including **Sectigo** and **Let’s Encrypt**, is planned and will be made available soon. This multi-CA approach gives organizations the flexibility to work with their preferred public trust providers while standardizing renewal, automation, governance, and monitoring through CertiNext. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
