If you are interested in an added level of protection, there are intriguing gadgets called Tiny Hardware Firewalls. These devices range from about $30 to $70 and connect via a network port or a USB slot to your laptop. They make the initial network connection, and so your computer's communication is always blocked before it calls out to the internet.
A proxy server is another way to conceal your real location. By transferring data through a proxy server the data appears to be going to that server, not you - so for example if you’re in the US and the proxy is in Switzerland, the website or service will think it’s talking to a machine in Switzerland. The main difference is that VPNs protect all your traffic while proxies tend to be limited to specific types of data, such as peer to peer networking or web browsing.
Tunneling protocols can operate in a point-to-point network topology that would theoretically not be considered as a VPN, because a VPN by definition is expected to support arbitrary and changing sets of network nodes. But since most router implementations support a software-defined tunnel interface, customer-provisioned VPNs often are simply defined tunnels running conventional routing protocols.
Put simply, a Virtual Private Network, or VPN, is a group of computers (or discrete networks) networked together over a public network—namely, the internet. Businesses use VPNs to connect remote datacenters, and individuals can use VPNs to get access to network resources when they’re not physically on the same LAN (local area network), or as a method for securing and encrypting their communications when they’re using an untrusted public network.

HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
