What is a VPN? Understanding Virtual Private Networks

You may have seen commercials promoting something called a Virtual Private Network, better known as a VPN. But what exactly is it and why do you need one?  

In layman’s terms, a VPN is sort of like a secret, well-hidden portal for your Internet service. For example, let’s say you’re mailing a package to a family member – but instead of sending that package directly to your family member, you send it to a friend in another city instead. That friend then mails the package to your family member for you. The post office has no idea what’s in the package or that you’re trying to send it through another person. They can only see that you’re mailing a package to your friend.  

A VPN does the same thing for your internet connection: It hides your location, it protects your data, and it lets you access blocked content. In a nutshell, a VPN keeps your online activity private and secure. Many IT providers recommend using a VPN alongside tools like secure email to protect sensitive information from cyber threats. 

The most popular use of VPNs is through streaming services. A VPN allows users to access streaming services in other parts of the world by changing the virtual location and encrypting Internet traffic. But VPNs aren’t just for personal use. Businesses use VPNs to create secure connections for remote employees or extend their network across multiple locations—often with the support of a managed service provider (MSP) to ensure everything stays secure and compliant.

Here are a few examples of why a VPN may be useful for you and your business: 

1. Data protection while using public Wi-Fi – You may be sending an important email to a client while sitting in your favorite coffee shop, but there’s no greater vulnerability than accessing an Internet connection in a public setting.  Now you’re at risk of cybercriminals intercepting unencrypted data on your computer.  A VPN encrypts your connection, making it impossible for hackers to steal your information.  

2. ISPs can’t track you – Internet service providers love to track and collect personal data about your browsing history and then sell that information to advertisers. A VPN will block ISP access and protect your browsing information.  

3. Bypass censorship – VPNs allow you to access and connect to servers all over the world, helping you obtain content that is either restricted or not available in your country. Whether it’s a news website, social media platform, or streaming service in another part of the world – you have browsing freedom with a VPN. 

When choosing a VPN service, make sure you’re looking for ones that provide strong encryption, fast speeds, and offer wide server locations for global access. This essential tool is perfect for protecting your privacy online so that you can browse safely and securely.
