Practical Uses of a Virtual Private Network You Need to Tweak it More
One of the most common uses of a VPN is for extending a private network to another place through the Internet. For instance, companies could allow their employees who are at home or on the move to connect to their company’s network even if they’re not physically in the office. This traffic would be effectively encrypted, hence, safe and secure from interception and eavesdropping by malicious individuals.
Virtual private networks aren’t necessarily for business use, and since the connection is secure and private, users could also anonymously access the Internet. It’s vital to note that your ISP or Internet Service Provider actually keep tabs on your Internet activity and could limit your allotted bandwidth once they uncover certain activities like BitTorent traffic and P2P file sharing. Additionally, the sites you visit obtain your location, IP address, ISP, operating system, browser, and screen resolution information among others. With a VPN application in place, however, you could hinder sites from spying by effectively hiding sensitive, identifiable data.
Likewise, if you’re used to using your mobile devices and connecting in Wi-Fi hotspots in restaurants, cafes, bars, train stations, hotels, etc., an unscrupulous user could easily keep track and collect your private data. Online banking and shopping might not be entirely safe due to the network’s open nature, and you never know when a hacker might target you. Connecting to a VPN prior to connecting to public Internet connections could eliminate these potential hazards, explains an expert from Private Tunnel. Furthermore, if you’re a frequent traveler and would like to access websites banned or blocked in that country, you could simply connect to your VPN application and unlock blocked sites and services.
Essentially, a virtual private network connects two computers privately and safely over the Internet. Companies use it for a wide variety of purposes, but if you think you’re safe behind your own Internet router at home, you probably could do without it. That said, as you could see from above, there are specific scenarios where you might definitely consider using a VPN.
