What is a VPN technology?
A number of netizens know today what is a VPN. It’s a virtual network between your device and a desired server.This technology was initially developed for employees of huge companies, who needed a remote access to their work computers without a security breach of a corporate network.
How does a VPN work?
For example, you live in France, but want to unblock all restricted content of Netflix for watching your favorite TV shows. What you need to do is just to change your French IP to an American one. All data that passes through a VPN connection will be encrypted, making you hidden on the Internet. Neither your ISP nor hackers can trace you when you are connecting to the Internet through a VPN. That’s why it’s crucial to use the best VPN provider with secure servers and robust encryption.
What is VPN protection?
A VPN technology has become highly popular nowadays. A lot of people all around the world prefer this software to protect their sensitive data and devices. There are three main elements that make a VPN thing number one when it comes to a secure and private Internet connection.
A huge number of servers worldwide is one of the main features of a decent VPN. Let’s see why it is so vital.
When you connect to a server on the Internet without a VPN, you transmit your data to this server and get all relevant information from it. However, when you use a VPN, you transfer your data to a VPN server and only then to a server you want to connect. This is how you stay anonymous while surfing the Net. What is crucial here is that all your data is encrypted and remain known only for a VPN.
Choose a VPN only with reliable servers and pay attention to the providers that don’t save or keep your personal info.
While looking for an ideal VPN, pay attention to this aspect. Encryption is the main reason why a VPN technology is so popular today. Even if attackers get access to your personal information, they won’t be able to decipher it.
All trustworthy VPNs use 128-bit or 256-bit encryption. These numbers refer to the length of the key and represent the possible number combinations. Even the fastest computer in the world will fail to decode 128-bit encryption, not speaking about 256-bit protection.
Protocols are used to protect all data that transfers via a server.
Exactly secure protocols allow you to create a secret and secure connection. There are a lot of protocols used by VPN providers: PPTP, L2TP/IPSec, IKEv2, SSTP, etc. However, OpenVPN is the fastest and the most robust today.
What is a proxy server?
To put it in simple terms, a proxy is a computer that “sits” between your computer and a server you are trying to connect. It is able to hide your IP and get past geo-blocking. A proxy server, as well as a VPN, makes you invisible on the Internet. However, there is one significant difference between a VPN and a proxy: a proxy doesn’t encrypt data.
How does a proxy server work?
When you visit this or that website, your computer sends your IP-address to the Internet. Using this address hackers can get access to your computer and steal your data. However, if you use a proxy server, it will change and hide your real location and IP, making them hidden on the Internet. Only a proxy server knows it, that’s why you have to choose the most trustworthy and best proxy.
What are the main types of proxies?
There are several types of proxies designed to solve different issues. However, all of them have a lot in common. Let’s see.
- CGI proxy
CGI can work only through browsers. For this reason, they are easy-to-use. You don’t have to be an advanced Internet netizen to use it while surfing the Net or create a chain from free anonymizers.
- Socks proxy
These proxy servers are able to work with almost all types of information on the Internet. However, browsers can’t work through socks proxies, a third-party program is needed in this case.
- HTTP proxy
This type of proxy is the most widespread. Actually, if someone mentions “proxy”, he or she means exactly this type. Earlier, these proxies were used only for viewing web pages, pictures or downloaded files. However, today even new versions of programs can work through HTTP proxy.
What to choose paid or free proxy servers?
Let’s see the difference between free and paid proxies. Paid proxies:
- Paid proxy servers are considered to be more stable and reliable. However, paid proxies don’t guarantee the absence of failures. Another advantage of using paid proxies is that you’re able to choose such parameters like response time, access rate, region, etc.
- Paid proxies are more reliable and stable. You can make your claims, in case of breakdown of server work.
- It is costly to create a long chain of paid proxies.
- They don’t require authorization.
- There are no restrictions on their use.
- However, a free proxy server can be overloaded.
- There are almost no long working free proxies.
- It is difficult to find a suitable free proxy. Of course, there are a lot of lists with free proxies on the Internet. However, 90% of such lists are out of date and with non-working proxies.
VPN vs proxy
Both proxies and VPNs are able to mask your IP, making you unseen on the Internet. It is possible to use proxy servers for anonymous browsing and bypassing geo-restrictions. However, when it comes to security on the Internet, it’s better to choose a trustworthy VPN provider.
Moreover, among free proxy servers, there are those that are risky to use. You have to be extremely attentive and careful while choosing proxy servers. What is more, a proxy does not encrypt your data and is not able to protect it. Your real location can be revealed either.
In contrary, a VPN is subtler software than a proxy. It not only helps you to get past restrictions from your country but also ensures online safety and privacy. By means of robust protocols, a VPN creates a secure tunnel and encrypts your personal data, making it unavailable for malefactors to steal or reveal it.
