Certificate Manager excels in automating certificate rotation and deployment but could enhance its offering by improving support for hardware security modules like Fortanix and providing more advanced, out-of-the-box integrations with public certificate authorities for DNS re-verification. Currently, the yearly DNS verification required by certificate authorities necessitates manual intervention, hindering full automation. This limitation, however, is not unique to Certificate Manager, as most tools lack the API integration necessary to automate the verification process with certificate authorities. Until such integration is achieved, the added security layer of domain verification will continue to pose a challenge for fully automated public certificate management.
