VPNs (virtual private networks) surged in popularity for their promise of secure, private browsing, but their capabilities may be overstated. So, while VPNs work, there are heaps of misconceptions about the security they provide and what they’re truly good for.
How VPNs Work
When you access the internet, your device (phone, laptop, or desktop PC) sends your request to a router, which then directs it to the modem. From there, the modem connects to your ISP (Internet Service Provider), which facilitates routing your data to the right destination. Both your public IP address (modem address) and private IP address (device address)are used to ensure your data is trafficked to the right place and the response goes to your device.
Using a VPN changes this process. The VPN app on your device encrypts your data before it reaches the router and modem. The ISP then routes your connection to a VPN server, where your data is decrypted, used to access the content you’re seeking, re-encrypted, and sent back to the ISP. Finally, your modem and router receive the encrypted data, and routes it to your device where the VPN app will then decrypt its contents.
A VPN essentially encrypts your data and masks your IP address by connecting to a VPN server, which adds a layer of anonymity and security when connecting to the Internet.
The Problem With VPN Services
Although using a VPN service masks your IP and encrypts your data, it doesn’t guarantee total online security or anonymity like ads try to convince you. There are some common misconceptions about using VPN for security:
Although VPNs add a layer of privacy and security, many fail to explain their limitations and provide blanket statements about how they make your online experience secure. This, in turn, can make people feel a false sense of security, leading to poor cyber hygiene.
VPN services also add several extra layers to your internet access. This can slow your internet speed and increase your latency, which will affect the responsiveness of time-sensitive applications like video calls, online games, and stock exchange monitoring.
What Is a VPN Good For?
VPNs serve a purpose but are not the ultimate answer to online security or anonymity. They’re useful for protecting your device when using public Wi-Fi or accessing geo-restricted content. However, with VPN prices becoming significantly more expensive after your first year of subscription, limited online protection, and the drawbacks you get from using one, is it really worth paying for one?
