Let's start with Apple does not "make one." At least, not if you are talking about VPNs. Based on your comments, it looks like you are looking to provide additional security when browsing the Internet, up and above, just accessing secure web sites (those that use HTTPS in their URLs) for everyday use ... not just for banking or other PIA sites. Is this correct?
If so, you would be looking for a "user-to-server" type VPN. These are also known as SSL VPNs. These work by providing a secure "tunnel" over your Internet connection between your computer and the VPN service provider's server. This server will act as a sort of proxy to "hide" your external IP address ... at least, in theory. Any traffic going across the tunnel will be encrypted.
If this is really what you want, then my first recommendation when considering which VPN provider you will want to go with, is avoid "free" VPNs. Why? Because, they have to make money some how, and typically, they do so by selling your browsing habits to other third-parties ... even if they can't provide the actual content.

Ok, now that I probably "scared you off" from getting a VPN, I do use them myself. FWIW, I ended up getting my VPN service from Private Internet Access (PIA). They are not free, but not expensive. They do not track your usage and provide VPN clients for Mac, PCs, iOS, & Android devices. They also provide a "family plan" so that family members can install and use their own copy of the client on their devices. Just to let you know, I do not work for PIA. I'm just a customer and have been using their service for about 3 years now without any issues.
