Performance Issues

How a VPN can slow down your internet speed

Using a VPN often affects your internet speed. This happens because the data you send and receive gets encrypted and has to pass through additional servers, increasing the time it takes to transmit information over the internet. Depending on the quality of the VPN service, users can experience anywhere from a negligible drop in speed to a significant decrease that affects browsing and downloading capabilities.

You can dive deeper into the specifics of data encryption on Wikipedia’s page about Encryption.

When latency-sensitive activities are impacted

Activities that require real-time communication like online gaming, video conferencing, and live streaming are particularly sensitive to latency issues. Using a VPN for these activities can introduce delays or “lag,” degrading the experience and performance. For example, in gaming, even a slight delay can make the difference between victory and defeat. Similarly, in a business video conference, latency can disrupt communication and create misunderstandings.

For a comprehensive understanding of latency in networking, refer to Wikipedia’s article on Latency (engineering).

Online Banking

Risks involved in accessing bank accounts through a VPN

While you might think using a VPN adds an extra layer of security to your online banking, it can sometimes introduce risks. For instance, if you’re using an unreliable or sketchy VPN service, your financial data could potentially get compromised. Also, consistently accessing your bank account from various locations, which is what happens when you use a VPN, can trigger security alerts. Your bank may flag these as suspicious activities, which could lead to temporary account suspension until you can verify your identity.

Before using a VPN for online banking, it’s crucial to read through your bank’s terms of service or consult their customer support to understand their policies on VPN use.

What a VPN hides

Two-Factor Authentication Conflicts

How using a VPN might interfere with 2FA methods

Utilizing a VPN can sometimes create issues with two-factor authentication (2FA), a security process in which a user provides two different types of identification to prove their identity. VPNs change your perceived location, and this sudden ‘movement’ can sometimes trigger security systems to flag your log-in as suspicious. This flagging may prevent you from receiving the 2FA code via SMS or may cause the system to block your login attempt altogether, thinking it is a possible unauthorized access.

For more information on how 2FA works, you can read Wikipedia’s article on Multi-Factor Authentication.

Scenarios where this would be problematic

This interference becomes a significant issue when you’re dealing with services that require high security, like financial applications or work databases. Being locked out of your account due to 2FA conflicts can not only be frustrating but also potentially disastrous if you need immediate access to sensitive information or functionalities. For example, being unable to complete a time-sensitive financial transaction because your bank’s 2FA system is rejecting your login attempts can have severe consequences.

Geo-restricted Content and Violation of Terms of Service

How bypassing geo-restrictions using a VPN may violate service agreements

Using a VPN to bypass geo-restrictions is a common practice. However, doing so can violate the terms of service for many online platforms. Streaming services like Netflix, Hulu, and Amazon Prime Video explicitly state in their terms that users should not attempt to access content from regions other than their own. When you use a VPN to change your virtual location, you essentially break these terms. This violation can result in temporary or even permanent suspension of your account.

For a broader understanding of geo-restriction practices, you can visit Wikipedia’s page on Regional lockout.

Examples of services that penalize for using a VPN

Streaming services are the most notorious for penalizing VPN usage. However, other platforms like certain e-commerce websites and digital content providers also have measures in place to detect and restrict VPN users. Even some online games have policies against VPNs to prevent unfair advantages or fraud.

For more details about how companies enforce their terms of service, you can refer to Wikipedia’s article on Terms of Service.

Data Encryption and Security Misconceptions

When a VPN doesn’t provide complete anonymity or security

Many people assume that using a VPN guarantees complete anonymity and security. However, this is not entirely accurate. While a VPN does encrypt your data and masks your IP address, it doesn’t protect you from all types of online threats. For instance, a VPN cannot protect you from malware or phishing attacks. Moreover, some VPN providers keep logs of your activities, and these logs could be accessed by third parties either through hacking or legal subpoenas.
