Hi there,

A SSL certificated signed by well known CA (certificate authority) allows you to offer SSL encrypted services to people/ devices outside of your enterprise and for them to trust the validity and source of that connection. That is because your public key has been signed by the CA and the public keys of these CAs are distributed to operating systems, which in turn allows this chain to be trusted.

A self-signed SSL certificate comes from an 'untrusted' source and has not been signed by a trusted CA. You can create your own CA within your enterprise and use it to sign all your internal certificates, this is a valid approach. You should only really start using publicly signed certificates once you are offering services to devices which cannot easily download and install the public key from your own CA.

cheers,

Seb.

It depends on the services/ features your customer wants to use and whether they will be accessed by people outside of your enterprise.

Let us know these and we can work out the type of cert you'd use for each.

cheers,

Seb.
