Self Signed vs purchased Cert

Moe-Ca

Hi,

A quick question for the experienced ones. What are the advantages when using a proper cert instead of the self signed one Other than the warning you get in browser when going to the fw URL?

another related question, will a purchased cert be able to intercept ssl traffic without having to install a cert on clients? i dont think so but wanted to double check as i think it has to be a verified root or intermediate cert which is something not a normal user/business can obtain

    Hi  

    The advantages of using a purchased certificate is the fact that you wont have to install the self-signed certificate or private CA certificate on every device that needs to connect.

    Some AV software will prevent you from connecting to a site with an invalid certificate.

    To answer your other question, no you cannot purchase a certificate that acts as a signing certificate.  This would make it easy for anyone to setup a MiTM attack.

    Thanks!
