I could not find specific information about connecting custom SSL.
A client of mine wants te be able to use it’s own preferred SSL types and supplier.
Although the SSL of Webflow looks fine (DST Root CA X3) due to the current fight between Google and Symantec, my client wants to be sure that their site uses the best SSL avaiable, and does not want to worry about, or more specific, wants to use their own preferred SSL certificate(s).
Check out the important fight between Google and Symantec, which possibly will lead to un-safe certificates from Symantec.
