Virtual Private Networks (VPNs) are very useful, whether you’re traveling the world or just using public Wi-Fi at a coffee shop in your hometown. But you don’t necessarily have to pay for a VPN service—you could host your own VPN server at home.
Your home Internet connection’s upload speed will really matter here. If you don’t have much upload bandwidth, you may just want to use a paid VPN service. Internet service providers usually offer much less upload bandwidth than they do download bandwidth. Still, if you do have the bandwidth, setting up a VPN server at home might be just the right thing for you.
