security solutions

Hello everyone! Today, let’s talk about VPN. Many people may not know much about it, or want to know how to choose a useful VPN that suits them… In fact, VPN is a technical means that can help us perform various operations more securely and freely on the Internet! First of all, we have to figure out the most basic question, which is what is a VPN ? Simply put, it is like building a special, encrypted tunnel for us on a public, sometimes not so secure Internet, so that our data can be transmitted in this tunnel, making it difficult for others to peek or make trouble! This is of great effect for people who need to work with public Wi-Fi outside, or friends who want to read some foreign website content and avoid regional restrictions!

So what are the main types of VPNs? There are quite a few types on the market, you have to sort it out carefully to understand and make it clear.

1. According to the usage object and scope, there are generally two major categories: VPN for personal use and VPN for enterprise level. Personal use is usually simple, lightweight, and easy to use. It mainly meets our basic needs such as surfing the Internet, watching videos, and protecting our personal privacy. Enterprise-level VPNs are much more complex and have much more powerful functions. They need to consider many employees connecting at the same time, managing permissions in different departments, and how to connect with various internal systems of the enterprise, etc.!

2. If VPN Solutions are divided according to technical principles, common ones include older ones like PPTP, but they are used less and less now, because everyone thinks that its security performance is not the top one; then L2TP/IPsec, which is much better than PPTP, and many devices also support it; and then, this is a very mainstream and popular one now. It is highly secure. Although the configuration is a little troublesome, it is particularly flexible and has strong adaptability. Of course, there are also new ones that are emerging, which are said to be very fast, and the code is simple and not easy to cause loopholes. It is a very potential young man!

So what key points should we pay attention to when choosing a VPN? This is a big question, and you have to think it through step by step.

First of all, the number of servers and the distribution location ! This is too important. There are many server nodes and a wide distribution of countries and regions. This means that we have more options to connect to, and it is not easy to cause a certain server to be particularly crowded and slow down. Moreover, if you want to connect to the network in which region, match the servers in the corresponding region, the success rate is much higher.

The second is the connection speed ! This is directly related to our experience of surfing the Internet. If the speed is too slow, you can watch a video card for a long time and open a web page for a long time, then you will be very anxious and get angry. No matter how safe it is, it is useless. Isn’t it annoying? So you have to find VPN providers with sufficient bandwidth and good network optimization.

And then there is the log policy ! This involves our privacy issues. You have to see whether the service provider will record our Internet behavior data, such as which websites you browse and when you connect. It is best to choose service providers who clearly promise that they are "no logs" or only record very little necessary information, and that this information will not be leaked to outsiders, so that they can feel at ease.

There is also a limit on the number of connected devices at the same time ! Now everyone has many electronic devices, including mobile phones, computers, tablets, and smart TVs at home. If one account can only connect to one device, it will be inconvenient. So we have to see if it can connect to several devices at the same time. If it is enough, we can use it ourselves.

When encountering problems during the selection process, provide global procurement services for weak current intelligent products!

Let’s talk about the tips when using a VPN to make it better and avoid traps

To regularly check and update VPN client software! Because software developers will frequently release updates in order to deal with the emerging new security threats and fix some minor bugs. If not updated for a long time, there may be some potential risks or functional shortcomings, which will affect the effectiveness and safety of use. So develop the good habit of taking a regular look and fashioning if you update.

Try not to use VPN to do some illegal and irregular things! Although VPNs give us a certain amount of network freedom, this freedom is based on compliance with laws and regulations and cannot be used indiscriminately. We must be a good citizen who abides by law. Otherwise, if there is a problem, it will be more than worth the loss!

If you are using a VPN solution in China, you must obtain and use it through formal and legal channels. Never trust those VPN software with unknown sources and are known as "free and super powerful". Many times, those may contain virus Trojans, or they will secretly collect our personal information, which is too dangerous!

Finally, let’s answer a few small questions about VPN that you may often ask, so that you can understand more comprehensively.

Q: Can a free VPN be used? Is it much different from paid ones?

Answer: Some free VPNs can be used temporarily to meet some very basic and simple needs. However, they usually have many restrictions, such as the small number of servers, the speed is particularly slow, the lot of ads is annoying to watch, and most importantly, how can it make money with a free VPN service? This makes people worry about whether it will make plans on our privacy data, and the security risks are relatively higher. Paid VPNs are generally much better in terms of server resources, connection speed, security, and customer service. They get what you pay for. For users with long-term and stable needs, it is recommended to carefully consider the payment option!

Q: Will using a VPN slow down my network?

Answer: This is possible, but how much slower it down? It depends on many factors. For example, if the server you are connected to is far away from your actual location, if it is particularly far away, the loss and delay on the data transmission route will definitely be large; there is also the current load of the server, if there are too many people connected, the pressure will be high, and the speed will naturally be slow; and the VPN protocol itself has different impacts on speed, as mentioned above, it usually performs better than other old protocols; of course, it is okay if the original network bandwidth you use is enough! In most cases, if you choose a high-quality VPN service provider and a suitable server, the slowdown will be within an acceptable range and will not affect normal use too much.

My personal opinion is that choosing a suitable VPN can indeed bring a lot of convenience and security to our online life, but you must spend time understanding and comparing more, choose according to your actual needs, and obtain and use it through formal channels, so that you can truly use it with worry and confidence!
