Lets say my company produces a device which can be connected to secure websites or it may act as some kind of server.
Lets say I produced 100 pieces of the same device. Should I get one SSL certificate for all of them or 100 unique certficates?
Or even better, Can I still communicate with a secure server without a certificate?
I need to know how it is done currently in the industry, for example in the case of mobile phones.
