The internet has become an integral part of our everyday lives. But as we grow more and more dependent on the internet, the risks to our security also get bigger, smarter, and more frequent.
That’s where a virtual private network (VPN) comes in handy – like a metaphorical shield protecting you from various issues such as mass data collection, corporate exploitation of sensitive data, and ISP tracking.
Sounds good, right? But how does a VPN work?
This guide aims to give you the lowdown on all things VPN and the clever ways a VPN protects your online security and digital privacy.
What is a VPN, and what does it do?
A VPN is a technology that works as a tunnel, hiding your online activity from prying eyes looking to track or intercept your data. It establishes a secure and encrypted connection between your device and the internet and routes your internet traffic through remote servers.
Encryption safeguards the sensitive information you transfer online, protecting you from potential cyber threats, data exploitation, and the lurking government. Routing the internet traffic through a VPN server masks your IP address and location, meaning that any data transmitted online leads back to the VPN and not your device.
Protects your browsing history
ISPs can track your every move online and keep a history of all sites you visit as they tie all information back to your IP address. They can then sell this data to the highest bidder and control what sites you can or cannot visit.
Using a VPN prevents both issues. ISP can only see that you’re connected to a VPN, but not where your connection travels after. It increases your privacy and helps unblock websites that may otherwise be unavailable to you.
Secures your IP address and location
A VPN hides your IP address, allowing you to browse online anonymously and live in peace in the knowledge that your online activity isn’t under surveillance. Additionally, because it sets your IP address to a different location, you can stream online services that are otherwise restricted in your own country. Bonza!
Acts as a layer of protection for your devices
Using a VPN can also guarantee an extra layer of security for your devices, especially when the VPN has extra security features, such as malware or phishing protection.
What are the risks associated with VPNs?
While VPNs are an incredibly handy bit of technology, you should be aware of some disadvantages.
- The threat of viruses and malware is still present. A VPN alone is not always enough to protect your device from viruses or malware. Be sure to install anti-virus protection and avoid downloading any suspicious files.
- Not all devices are protected automatically. A VPN works on the device level, so you will need to install a VPN on each individual device that connects to the internet. You can also install a VPN on some routers to protect all devices connected to your network.
It can slow things down. Routing and encrypting the connection uses your internet and computational resources, so you may find that the speed isn’t what it used to be. This can be incredibly annoying; however, it’s a small price to pay for that additional layer of protection.
