What do I need to know before using a VPN?

Before using a VPN, you should understand what a VPN is and how it works to protect your privacy. Evaluate different VPN providers based on your needs and budget. Install and set up the VPN properly, keep it updated, check for IP/DNS leaks regularly, and be aware of potential security threats and their solutions.

What do I need to know before using a VPN

Choosing the Right VPN for Your Needs

It is essential to choose a VPN that matches your specific needs and purposes, which can vary significantly based on individual preferences or organizational requirements. This section will examine various VPN use cases, namely for personal use, business use, streaming, browsing, and gaming, and how different cost factors affect the value-for-money proposition.

For Personal Use vs. Business Use

When considering a VPN for personal use, consider options that prioritize simplicity and ease of use. For instance, NordVPN offers a straightforward interface and costs around $3.71/month for a two-year plan as of 2021. It provides over 5400 servers across 59 countries, perfect for accessing geo-restricted content or safeguarding your privacy when browsing.

On the other hand, business VPNs should focus on security, scalability, and collaborative features. As an example, Perimeter 81 starts at $10 per user/month and provides team management features, dedicated servers, and 24/7 customer support.

VPNs for Streaming vs. Browsing vs. Gaming

If your primary purpose is to stream content, consider a VPN like ExpressVPN ($8.32/month for a one-year plan), renowned for its fast speed, which averages around 85 Mbps on a 100 Mbps connection, and its ability to bypass Netflix’s VPN blocks.

For general browsing, look for VPNs with solid security features.

For gaming, latency and server location can significantly impact your experience. A VPN like CyberGhost (from $2.75/month) has dedicated gaming servers, designed to provide low latency and high-speed connections.

Cost and Value for Money

The monthly cost of VPNs can range from free (with limitations) to over $10/month for premium services. However, the cost isn’t the only factor to consider. Assess the number of devices allowed per account, the number of servers and locations, speed and stability, security, and privacy features, and customer support’s quality.

For example, Surfshark is a value-for-money option at $2.49/month (for a two-year plan), offering unlimited device connections, robust security features, and excellent customer service.

Installation and Setup

Setting up a VPN usually requires only a few simple steps, which differ slightly depending on the VPN service and device you’re using. Below, we will outline the standard installation process and address some common setup issues.

Step-by-step Guide for Typical Installation

For this example, we’ll use ExpressVPN, one of the top-rated VPN services. This process generally takes about 5 minutes.

  1. Purchase a VPN Subscription: Visit the ExpressVPN website and choose a plan that suits your needs. Once you complete the payment process, you’ll receive an activation code.
  2. Download the VPN Client: Download the ExpressVPN app suitable for your device (Windows, Mac, Android, iOS, etc.) from their website or respective app stores. The download file is typically around 30MB, requiring minimal storage space.
  3. Install the VPN Client: Open the downloaded file to start the installation process. Follow the prompts, which typically involve accepting the terms of service, choosing a location for the installed application (default is usually best), and confirming the installation.
  4. Set Up the VPN Client: Once installed, open the ExpressVPN application. Enter your activation code when prompted, which links your app to your paid account.
  5. Connect to a VPN Server: The application interface should now display a large power button. Clicking this will automatically connect you to a recommended server. If you prefer, you can also choose a server in a specific country.

Troubleshooting Common Setup Issues

Here are some common VPN setup problems and how to solve them:

  1. VPN Won’t Connect: This might be due to a problem with your internet connection, so try checking that first. If the issue persists, try switching to a different server or resetting the VPN app.
  2. Can’t Access Certain Websites: Some sites might block traffic from known VPN servers. If you’re unable to access a particular site while connected to the VPN, try disconnecting or switch to a different server.
  3. Slow Internet Speed: If your internet is significantly slower when connected to the VPN, try switching to a server that’s closer to your actual location, as it might provide a faster connection.

Maintaining and Updating Your VPN

Regularly updating and maintaining your VPN client ensures optimal security and performance. This section will cover how to ensure your VPN client remains up to date and how to regularly check for IP/DNS leaks.

Ensuring Your VPN Client Is Up To Date

VPN providers often release software updates to improve functionality, fix bugs, and patch potential security vulnerabilities. Here’s a step-by-step guide on how to update your VPN client using the NordVPN application as an example:

  1. Check for Updates: Open the NordVPN app on your device. Go to the settings menu, usually represented by a gear icon, and find the ‘Check for updates’ option. Click on it to see if any updates are available.
  2. Download Updates: If an update is available, the app will usually prompt you to download and install it. The download size typically ranges between 15-50MB, depending on the update.
  3. Install Updates: Click ‘Yes’ or ‘Update’ to begin the installation process. The application will guide you through the steps, which usually includes agreeing to terms and conditions and verifying the installation.
  4. Restart the App: Once the update process is complete, you may need to restart the app for the changes to take effect. Some updates might also require a device restart.

Periodically Checking for IP/DNS Leaks

Regularly checking for IP and DNS leaks is crucial to ensure your VPN provides the privacy it promises. Here’s a general process on how to perform these checks:

  1. Connect to Your VPN: Open your VPN client and connect to a server of your choice.
  2. Visit an IP/DNS Leak Test Site: There are many free websites that offer this service, such as ipleak.net or dnsleaktest.com.
  3. Run the Tests: These websites will automatically check if your real IP or DNS queries are being leaked. The test usually takes less than a minute.
  4. Interpret the Results: If the tests show your VPN server’s IP address and DNS rather than your own, your VPN is secure. If your own IP address or DNS shows up, your VPN might be leaking, and you should contact customer support.

Bad Hackers  Attacks VPN And Solutions

VPNs enhance your digital security, but they are not invulnerable. This section will identify common types of attacks directed at VPNs and provide practical solutions for each.


Brute Force Attacks

In a brute force attack, hackers try to crack your VPN password by systematically attempting all possible combinations. They often use automated software, so even passwords that seem complex might be vulnerable.

Solution: Use a robust and unique password for your VPN account. Consider using a password manager to create and store complex passwords. Some VPNs, like ExpressVPN, offer features like auto-generated strong passwords and built-in password managers for enhanced security.

Man-in-the-Middle Attacks

In a Man-in-the-Middle (MitM) attack, the hacker intercepts communication between your device and the VPN server, attempting to decrypt the data.

Solution: Use a VPN with strong encryption standards. For example, NordVPN offers AES-256 encryption – currently the most secure. Also, consider using VPNs with an Internet Kill Switch feature, which automatically disconnects your internet if your VPN connection drops, preventing unencrypted data from being sent.

IP Leaks

Sometimes a VPN can inadvertently leak your real IP address, which can be exploited by bad actors to target your system.

Solution: Regularly check for IP leaks using websites like ipleak.net. If leaks are detected, contact your VPN provider’s customer support. Some VPNs offer built-in leak protection to guard against this vulnerability.

VPN Traffic Analysis

By analyzing your encrypted data’s size and frequency, a skilled hacker might be able to infer some information about your online activities.

Solution: A VPN offering obfuscation methods, such as Surfshark, can help mask your VPN traffic, making it look like regular HTTPS traffic, and thus harder for hackers to analyze.
