How do VPNs Work & Why Do They Require A Lot Of Data Analysis?


As popular as the Internet has become, it is not safe. Hackers are always prying on your moves to steal data and sensitive information. Totalitarian governments don’t want you having the freedom to access the World Wide Web as you wish. To be safe, the digital savvy use VPNs.

What is a VPN?

Short for a virtual private network, a VPN lets you access the Internet securely by hiding your Internet activities. Providers use servers located in different geographical points to route your personal computer’s connection.


Your IP address is hidden and your computer’s data is encrypted. When surfing the Internet, you become an anonymous user to attackers. Without leaving your home, you can be routed with a server located overseas. And since your data is completed shielded with military-grade protection, hackers and governments can’t identify your IP address.

How do VPNs Work?

A normal connection works in a simple way. Data from your personal computer is transmitted to the Internet openly. Anyone with the right tools can peek to see what you are sending.

For private virtual networks, the action begins when you start the client (software). The VPN encrypts your data using advanced cryptographic techniques. Whether you are using public WiFi or mobile data, your data is first shielded. Your Internet Service provider can track that data and neither can anyone else.


In an encrypted format, the data is tunneled by the VPN to one of their secure servers. You are then connected to the Internet securely. If anyone tries to track you; your IP address reflects the location of the provider’s server.

Because of the security they provide, VPNs are used by everyone who understands the need to secure their connections. Hackers, marketers, banks, gamers—millions of people around the world use virtual private networks to secure their connections.

Why do they Require Data Analysis?

To secure your connections, VPNs are programmed to analyze your data first. Depending on the exact encryption technique used, the software groups your data into packets and encrypts every important detail.

VPNs work in a tunnel-like environment. On one end is your personal computer. The other end is the online destination you want to visit. When accessing the Internet without a private network, most of your data can be hijacked along the tunnel. VPNs analyze your data to identify the significance and encrypt the information using secure methods.

• IPSec

If a VPN uses the encryption method, the complete data packet on your PC is encoded. When combined with another technique (L2TP), your connection improves. The Layer 2 tunneling method builds a secure tunnel the IPSec protocol can transmit data through. IP security also handles data integrity checks and confirms your data reaches the end destination securely.

• PTTP Protocol

Point to Point tunneling analyzes your data and tunnels it to the end destination. For encryption, VPNs use AES-bit 256 to encrypt the data in ways hackers, governments or other websites can’t decode. In recent years, PTTP connections have been replaced with more advanced techniques.

• Secure Shell Protocols

Best for overriding government-imposed firewalls, SSH creates a safe VPN for accessing the Internet. Instead of encrypting data; the protocol secures the channel used to go online. By routing Internet traffic from unique servers, you are able to access the Internet even though your data may be unsecured.

• Internet Key Exchange, Version 2)

Commonly known as IKEv2, the tunneling protocol is one of Microsoft’s many transmission techniques. It was built to replace older protocols like PTTP and so far, it has worked. Nearly all the major VPNs use IKEv2 for transmission but mostly as an additional method.

• OpenVPN

OpenVPN is the most popular data analyses and encryption technique. It relies on Microsoft’s SSL web encryption but without any flaws. The protocol is also open source and uses advanced military-grade encryption to enable secure connections.

When looking for a VPN, whether the provider uses OpenVPN is one of the features most people look at. The encryption protocol analyzes all important information and uses the SSL ciphers to encrypt all important data.

Are VPNs really Secure?

Many IT professionals agree that VPNs are not universally secure. You won’t get the protection needed by simply connecting with any provider. There are three factors that determine the safety of the exact provider?
  1. The VPN’s security policies
  2. The Provider’s technology limitations
  3. Government-imposed legal policies
If a provider keeps logs as you surf the Internet, you are not safe. The company could reveal your information to any interested party. Some VPNs don't use advanced encryption methods. Others use unsecured DNS connections. Your data can be leaked at any point of the transmission process.

Lastly, governments can force providers within the country to keep logs or hand over any data they suspect. Some nations even have an alliance like the 5-eye alliance. If a VPN operates in any of the countries, it’s likely your connections can be handed over to governments.

How to find a safe VPN

A good VPN secures your connections. It protects you from hackers and enables you to access data you wouldn’t with regular connections. To find a reliable provider, first review their privacy policies and encryption methods.

If the company keeps your logs, understand that you won’t get total protection. Some provider may keep logs about your bandwidth and chosen servers. That’s okay as it is meant to improve their services. Keeping any other logs exposes you.

The encryption techniques used determines the level of security accorded. OpenVPN and IPSec and IKEv2 are the standard protocols. With encryption assured, review the VPN to find out if it has a history of leaking IP addresses. You want to pick a safe company that won’t leak any of your data.
Security assured; speed is another important factor. VPNs slow down your connection speeds. Look for a provider known for fast speeds in all areas it serves. Don’t ignore customer support as you may need it. Evaluate the prices and pick a secure provider whose pricing offers great value for money.
