Key Takeaways
- VPNs encrypt data and mask IP, adding security and anonymity when accessing the internet.
- Common misconceptions include full anonymity, protection against all hackers, and complete ISP privacy.
- VPNs are beneficial for accessing geo-restricted content and securing data on public networks.
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:
- Full Anonymity: VPNs can mask your IP but don’t stop website trackers, which can still use cookies and other tracking methods. Additionally, VPN providers can see your online activity if they log data, even if they claim otherwise.
- Protection Against All Hackers: A VPN can secure data on public Wi-Fi but doesn’t protect against credential-stealing malware or phishing attacks. Other security tools, like antivirus software, remain essential.
- Complete ISP Privacy: VPNs hide data from ISPs but shift trust to the VPN provider, which could potentially log your activity.
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?
Considering the benefits and the drawbacks of using a VPN, subscribing to a VPN service doesn’t seem all that useful. However, in my opinion, if you subscribe to a VPN, it should be for these two reasons:
- Accessing Geo-Restricted Content: VPNs allow users to view region-locked content by appearing to connect from other countries. This can work for accessing streaming services or websites only available in certain areas.
- Securing Data on Public Networks: VPNs are helpful on public Wi-Fi by encrypting data, which prevents snoopers from intercepting information. This added privacy can be valuable in public spaces but doesn’t replace other security practices.
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?
