How Does a Virtual Private Network (VPN) Provide Additional Security?

A virtual private network (VPN) provides a secure connection between your computer and another network or device. This secure connection extends to the resources you access on the network, such as websites, email, and instant messaging apps. By using a VPN, you can rest assured that your personal information is safe, whatever you connect to on the network.

A VPN can improve your overall security by shielding you from eavesdropping, tampering, and connection problems. It can also prevent cyberattacks and data breaches by keeping your personal information private. Many providers offer full military-grade encryption, plus they keep no logs of your activity, which means they cannot be seized by law enforcement.

Why Use a VPN With Your iPhone

Many people use a VPN with their smartphones to access resources on the go. Even if you have a perfect connection at home, your mobile network may not be as secure as you think. This is because mobile networks are generally more open to attacks from eavesdroppers and hackers. A VPN can protect your personal information as you browse the web on your phone, so you can be sure that your connection is private and that no one can access your data without your permission.

Not only that, but you can use a VPN to gain additional security benefits on your phone. For example, let’s say that you’re connecting to a Wi-Fi network at the airport. Your phone can be susceptible to man-in-the-middle (MITM) attacks, where a third party gets access to your personal information, such as your email and passwords. You could use a VPN to encrypt all your traffic, including the Wi-Fi network connection. Now when you use that Wi-Fi network at the airport, your data will be encrypted so no one can eavesdrop or tamper with it as you travel the world and get to the office on time.

Another benefit of using a VPN with your smartphone is that you can create a secure network within your company. For example, you could use Google Apps or Microsoft 365 to create a VPN within your company that allows employees to securely connect to resources, such as company email servers and private cloud storage. This is ideal for companies that want to stay in touch with their employees, as well as companies that want to provide their employees with additional security.

How Does a VPN Work?

VPNs work by establishing a secure link between your computer and another network or device. This link is established through a tunnel, which is a private connection that doesn’t go through any public networks. Your computer becomes your VPN’s gateway, meaning that all the traffic is routed through it. This traffic is encrypted so that only the intended recipient can read it.

The VPN software installed on your computer or mobile device will establish this secure link and provide you with a secure IP address that can’t be traced back to you. This IP address will then be used by you to access a private network or resource, such as a website or email account. Your computer will then behave like it’s connected to this private network or resource, meaning that all the websites you visit will be encrypted and no one will be able to see or block your communications with other devices on the network.

Since your VPN gateway is your computer or mobile device, you will have to install and run VPN software on it. This software can be very lightweight, so you won’t notice any performance drop even if you have a slower computer or mobile device.

Features You Should Look For In A VPN

There are several features you should look for in a VPN, which will help you determine if it’s the right fit for your needs. For example, does the VPN encrypt all your traffic, or just the traffic between your computer and the VPN? Does it log all your activity? Does it support authentication? Does it provide data back-up and recovery? Does it integrate with other software, such as security programs?

The first thing to check for is whether the VPN encrypts all your traffic or just the traffic between your computer and the VPN. If you’re only connecting to one network at a time, the latter is the standard option and is usually enough. This means that all the data sent over the connection is encrypted and unscrambled so that only the recipient can read it. However, if you’re connecting to multiple networks at the same time, then you should look for a VPN that encrypts all the traffic, including the traffic between the networks you’re connecting to. Some VPNs are still “split-tunnel” VPNs, which only encrypts the traffic between your computer and the VPN, and not the traffic within the VPN.

Types Of VPNs

There are several different types of VPNs to choose from, which means you’ll have to make a decision based on your needs. For example, you may want a VPN that is easy to set up and use, or you may want a VPN with the utmost security standards. Depending on your needs, you can choose from several different types of VPNs.

To start, you should look for a VPN that is compatible with your operating system. This will depend on what type of device you have. If you have a Windows PC or laptop, then you should look for a VPN that is compatible with Windows. If you have an Android phone or tablet, then you should look for a VPN that is compatible with Android. If you have an Apple device, then you should look for a VPN that is compatible with macOS and iOS.

Next, you should look for a VPN that has a good reputation. tracks online reviews, and based on those reviews, they can determine the reputation of a given VPN. If a VPN has a good reputation and meets your needs, then you should consider it.

Then, you should look for a VPN that is licensed and regulated by the government. It is also a good idea to check with the EFF or the ACLU to make sure the government isn’t trying to sneak in any backdoors. Most VPNs come with a privacy policy that you should study before you use the service. This policy should lay out how the provider intends to use and protect your personal data. If a VPN is part of a parent company that is regulated by the government, then check with the regulator to make sure the company is adhering to the proper standards.


When choosing a VPN, you also need to consider how secure it is. The most important thing to look for here is encryption. If your data is encrypted, then it cannot be accessed by anyone without the encryption key. The next most important thing to look for is the strength of the encryption. The better the encryption, the better the security.

If you’re connecting to a public Wi-Fi network at the airport, then you should look for a VPN that has military-grade encryption. This does not mean that the rest of the VPN is protected by military-grade encryption, so you should not assume that just because your data is encrypted that it is secure. Most free VPNs that you can download and install don’t provide any security guarantees; therefore, make sure you’re connecting to a VPN that is trustworthy. Since VPNs can be used to bypass geographical restrictions, make sure you’re connecting to a VPN that is based in a country that has strong privacy laws.


There is one type of VPN, which has quickly become the standard, that you should avoid at all costs: OpenVPN. OpenVPN is one of the most popular VPNs, but its encryption standard is easily crackable. If you are encrypting all your traffic, then there is no reason to use OpenVPN. Since all your data is already encrypted, there is no security gain from using OpenVPN. On top of that, using an OpenVPN VPN will cost you money in the long run, since you have to pay for each subscription individually.


A VPN that you should look into is the Point-to-Point Tunneling Protocol (PPTP). This is a less secure alternative to the standard VPN protocol, OpenVPN. With OpenVPN, all the data is encrypted, but it is also encrypted with SSL or TLS, which are two more secure alternatives to PPTP.

While OpenVPN is the standard for VPNs, and for good reason, PPTP is still widely used, especially in China. If you’re connecting to a VPN in China, then you should look for a PPTP version. Not only is it more secure, but you won’t be bothered by the government or anyone else, as PPTP is a dial-up protocol, which means it doesn’t require you to have a constantly connected Internet connection.
