I'm running a vulnerability scanner on my network and am realizing just how many things are running self signed certs. Things such as internally face web apps, laser printers, switches, etc. I really don't see a large security risk here as they are internally facing but would like to clear these vulnerabilities off my report so when I take it to the execs they don't see them. Does anyone have a lead on cheap certificates? I don't want to pay a lot since I really don't want to apply them in the first place.
