What are the actual risks associated with an incomplete certificate chain
I read about certificate chains and I think I understand the concept but I seem to not understand the potential risks, for instance SSLLabs checks and states if a certificate chain is incomplete but still rates certificates with incomplete chains very highly (
A) so this implies to me that the chain doesn't seem to be that important, whereas my understanding is that the chain is a trust issue and so that should be very important.
What security loops can effect me if I do not have a complete certificate chain?
Reviewing my source this morning, I find that the certificate chain issue has been resolved; prevously it stated:
Certificates provided 2 (2936 bytes)
Chain issues Incomplete Chain
But this morning it states:
Certificates provided 3 (4716 bytes)
Chain issues None
This maybe because I told the company about this, or maybe that it's simply a fix on the cloudhosting, or some other thrd party issue.
