The AutoInstall SSL™ process varies in time, as it is largely dependent on the API response time of Certificate Authority.
In our testing, both RapidSSL and Comodo certs typically take just under one minute to install, while the more premium brands, like Symantec, Thawte, and GeoTrust, can take around 5 minutes to complete the installation.
However, it is important to note that while response time varies, it typically takes just minutes and is significantly quicker than performing manual installation. The time elapsed is dependent on CA responsiveness.
