      I've never bothered to setup a certificate for anything internal. I know who they are even if the browser doesn't.

        That's my stance as well.

          Self-signed isn't too bad if you have a way to install your own Root CA to the computers.

            In a windows environment with AD I setup a domain CA and all the servers and devices get an internal SSL that is trusted by the devices joined to the domain. That's the only use I do for internal SSLs but it takes some time to setup though.

              That is not self signed. That is signed by a trusted (local) CA.

                I plan to. However, I'm still learning the whole process for a local root CA and have hundreds of projects that are currently higher priority so I haven't had time to look into it.

                  Here’s a few sites I’ve been using to setup a local CA.

                  This one is pretty basic.

                    I think that local CA is us, we often think of it as self signed. Just a way to trust something that we signed ourselves.

                      A local CA, is nothing like a system generating a basic self signed cert.

                      A local CA can (more) easily be trusted by all browsers on the network.

                      Self-signed certs would all have to be individually trusted.

                        are there any good articles on how to create a local CA?

                            Near-zero value in someone attacking is what I meant. Not a zero-value in what is provided by the systems. Also there is nothing confidential or needing "security" from a business perspective, which is why I ask is SSL worth it for these types of Intranet sites?

                            You need SSL for everything period. Even if it's a self-signed cert it's fine... just allow the exception in the web browser and be done, or use an internal certificate if your browsers are set to trust the root... or a domain wildcard cert would work just fine. It's easy to do.

                            You could set out a reverse proxy for use with Let's Encrypt, and use the reverse proxy for all of your internal-only web servers. On the reverse proxy, you can limit each site config to only pass internal IPs only. That's what I did for a few. For example, if you add this in:

                                allow 10.0.0.0/8;
                                allow 172.16.0.0/12;
                                allow 192.168.0.0/16;
                                deny all;
                            

                            It will not proxy anything unless it comes from an internal IP.
