First, let's establish a point. 39% of Wi-Fi connections in the USA are insecure because the data transmitted through these Wi-Fi networks is not encrypted. In addition to this, it was found that many internet users do not use the recommended encryption protocols when transmitting data. As free public Wi-Fi networks are extremely vulnerable, a VPN for the USA is the first app you should download.
1. Strong Encryption - A mandate for public Wi-Fi
In the wake of the COVID-19 pandemic, cases of cyber attacks have increased by 300%. Encryption makes it almost impossible for an intruder to read the contents of your data. But, how does encryption actually work? Encryption converts readable data into random, unreadable packets. The intended user can decrypt the content using a key. In this way, the data is transmitted in an unreadable format, but it is converted to readable mode when received. If you need to connect to public wifi, we recommend that you use AES-256 encryption (with VPN service offers protocols such as IPSec and OpenVPN).
2. Anonymity is mandatory when using a public Wi-Fi
Let's consider this from the perspective of an intruder. An intruder will need some data points to start a cyber attack. The cyber attacker will want to know your IP, location and other basic information. However, your VPN cleverly masks your IP and also hides your location. When you connect to a VPN network, you are hitched to a VPN server. By then, your IP and location will be equivalent to the IP and location of the VPN server you are locked into. This way, it appears that your real IP and location remain anonymous. Amazing. Isn't it?
3. The VPN Tunnel is a must when you use a public Wi-Fi network
Here's another interesting security loop. A VPN creates a virtual tunnel between you and your internet destination. All your internet transactions take place inside the tunnel. No one else can peer into the tunnel and snoop on the transactions that are taking place. In addition to overlaying information, the tunnel prohibits ISPs from tracking your Internet activity as well.
4. Stay away from legal hassles of using public Wi-Fi
When you use public Wi-Fi, you need to abide by the terms and conditions of that network. But the truth is that some networks have terrible terms and conditions. They may ask you to tick a T&Cs button. These hidden terms and conditions can sometimes get you into trouble. However, after you have installed a VPN, most of your internet activity is confidential. This way, all of your user behaviour will not be noticed by your network administrator or ISP.
5. Access restricted content
Generally speaking, access to website content is not restricted in the USA, so you won't need to use a VPN in most cases. However, it will come in handy if you travel to another country where information channels are blocked.
In short, you may want to use a VPN whenever you establish an internet connection through your device. For security reasons, we recommend that you sign up for the best free VPN before connecting to public Wi-Fi.
