Let’s say you want to write a letter to another person in another country. But to get there, you have to go through other countries and you don’t want anyone else to read it.
In addition, people in the destination country want to make sure that the letters they receive are really from who they say they are.
How does a VPN keep me secure?
Then you encrypt the letter. But someone could intercept your letter and see who it is addressed to, and then try to impersonate you and send your own letter to the same person. But if you encrypt that person’s address, no one who handles the letter can deliver it because they cannot read the address.
Therefore, the country of destination establishes a special service for all its residents: one person is assigned in the country to be a “proxy” for everyone in the country. So, when I send my letter, I encrypt everything, including the address.
I fill in that message in another envelope addressed to the proxy. The letter goes through all other countries and anyone can look at it, but the only thing they can read is the address of the attorney, not the address of the person to whom it is really intended. Eventually, the proxy obtains the envelope, opens it and deciphers the letter inside and then reads the address of the destination and delivers it.

The proxy is very trustworthy: the recipient trusts that the proxy will not retain, alter or redirect any letter badly, and the proxy guarantees everything it delivers. In addition, the proxy vpn is well trained in security: it never uses a password as a ‘password’ nor any of the stupid things that ordinary people make compromise security.
It’s called a virtual private network because, even though the envelope passes through many hands, its content is completely hidden from anyone between you and the proxy, so it’s as if you had your own private route to the proxy.
Of course, someone in the middle can drop the message completely and not pass it to the proxy, but the messages can be lost even if you really had a private messenger to take the envelope to the proxy, so you would have to deal with the lost messages. anyway, through thanks, etc.
Personal VPN Service
There are three ways in which VPNs are used. The goal of all three is to connect two points securely.
1. Site to site: it has two offices and you want to be able to access shared files, internal websites, etc. from both locations. A VPN allows you to do that safely, which is also known as creating a WAN (Wide Area Network)
2. Remote worker to the office: has an employee (or several employees) who need to access the previous resources remotely. You can install a client on the remote worker device (smartphone, tablet, computer) that provides secure and encrypted access to the office network.
3. Personal VPN: A personal VPN is used to encrypt traffic between you and the Internet. Users choose this so that their traffic cannot be tracked or through firewalls that block access to certain sites (as in some countries such as China, Iran, etc.). Essentially, a direct connection is established between your device and a server somewhere outside the country. From there, you are free to search the web!
Key Benefits of Choosing ExpressVPN
VPNs come in all flavors and sizes using a wide range of technologies (protocols) and typologies. There are hardware VPNs that require manual configuration and network knowledge. Then there are the software VPNs that may or may not require configuration. There are a lot of personal VPN providers that usually charge $ 5- $ 10 / month for that service.
Top 5 Significant Benefits of Using a Virtual Private Network (VPN)
The virtual private network, usually called VPN, is an inspiration for tunneling. The packets are constructed in VPN format and, therefore, encapsulated in the provider of another protocol.
After that, those packets are transmitted between the VPN server and the client with the decapsulation in the receiving part. The VPN could exist with the IP of any country.
Upon request, the provider can configure the particular VPN with its particular IP for any of those countries along with additional services and benefits for customers.
Benefits of Using a Virtual Private Network
One of the most amazing parts of VPN benefits is allowing someone to modify the IP no matter where they are when they are on a business or travel trip.
After modifying the IP, you can use it to navigate those websites that are strictly only for your users.
VPNs mask your IP address to provide privacy
Each time you log on to the Internet, you are assigned an IP address that uniquely identifies your computer or mobile device. The problem is that all your online activities go back to this IP address. This includes every Google search, every website you visit, the things you buy, the links you click on, the comments you leave on social media and much more.
One of the main benefits of a VPN is that it hides its IP address so that its activities cannot be tracked. It does this by sending it to the Internet from a server in a different gateway city or country with a masked IP address. Due to the ability of the VPN to disguise your real IP address, your identity, location and online activities are kept private on the web.
VPNs protect private data through public Wi-Fi
The use of public Wi-Fi in airports, hotels and coffee shops without a VPN is a risky proposition. Even if you use a password to connect to public Wi-Fi, it is not secure. With a little motivation and knowledge, hackers can easily intercept, read or steal your data. This includes things like phone calls, emails, chats, logins and passwords.
Instead of leaving your data exposed, a VPN creates a hidden tunnel for your data. It does so by encrypting your Internet traffic within encapsulated data packets, creating your own private network through public Wi-Fi. With a VPN, your data is virtually impossible to see by external forces, keeping your information private.
VPNs allow access to geo-restricted content
A VPN on a smartphone asking if the user wants to tunnel to Germany.
Whether you travel abroad or live in a country that is not licensed to broadcast from, for example, Netflix or Amazon, you do not have to allow content restrictions to depress you. Instead, you can use a VPN to fake the IP address of your computer and avoid bans on geo-restricted content. How does this work?
For example, let’s say you are in Australia. You can log in to the EE server. UU. From your VPN to obtain a US-based IP address. UU. This makes it appear that you are physically in the US. UU., Which allows you to access your favorite movies and TV shows. This tactic also works in reverse. If you are in the USA UU. And you want to access programs in Australia, just use one of the Australian servers on your VPN.
VPNs can bypass censorship
It is no secret that many countries today impose the oppressive censorship of the Internet on their citizens. For example, China prohibits Facebook, Twitter, Instagram, Pinterest and Flickr. Meanwhile, many VOIP-based services, such as Skype and WhatsApp, are banned in parts of the Middle East.
If you live or are visiting a country with censorship, the use of a VPN can help you avoid these restrictions and access all World Wide Web and VOIP services. Just be sure to sign up for a VPN service before entering a country with current restrictions. Often, VPN download sites are also banned in these countries.
VPNs allow access to less expensive trips
Airlines and online travel brokers are known to manipulate the prices of air tickets. A less known benefit of VPNs is that you can book cheaper airline tickets based on your geographic location.
To get a cheaper flight, try to log in to a VPN server in a country that has a cost of living less expensive than where you are. To get the lowest price, try comparing from multiple VPN servers. This VPN benefit can also work to book rental cars or hotels.
Hulu.com is one of the TV Streaming Show websites in the USA, Which is only for residents of the United States. If you are not a US resident. And you want to log in to Hulu.com, you won’t be able to do it. However, if you are using a US VPN., The IP will automatically change to US IP.
This will allow you to navigate this website, as it already recognizes US UP. In addition to Hulu.com, VPN is also applicable to Facebook and Twitter if you are in China, since they blocked these websites there.
These days, people always try to find the best way to prevent others from following us while browsing. VPN will be one of the best solutions to protect this. It can help protect and prevent the Internet service provider (ISP) of the website owner from tracking our activities while browsing.
The way in which VPN does this is to make a connection only to the server and it will not notify the activities it performed. You will only become anonymous by hiding your real IP. By using a higher level of VPN encryption, it will cover your existing IP and protect it in your Internet browsing.
As a result, no one will know your location, since you will only notice your VPN IP instead of the real one. This is especially important when browsing in public areas through Wifi Hotspot.
In addition to these advantages, you can also enjoy cheaper VOIP calls compared to other VOIP service providers such as Skype, which is one of the most famous. Just take an example, someone from Singapore who is working in the USA. Enjoy approximately 90% of the lowest price when connecting Pfingo (top VOIP service provider in Singapore) with VPN compared to Skype. In addition, you will also enjoy better quality calls when using this VPN service.
In addition to that, VPN does not need additional installation since operating systems such as Mac, Windows and Linux support VPN configuration. Simply put, Express VPN will provide you with many advantages you need and you will definitely enjoy it.
Top 5 Significant Benefits of Using a Virtual Private Network (VPN).
A virtual private network (VPN) extends a private network through a public network and allows users to send and receive data through public or shared networks as if their computing devices were directly connected to the private network.
Virtual Private Network and Benefits
Therefore, applications running on a computing device, for example, a laptop, desktop computer, smartphone, through a VPN can benefit from the functionality, security and administration of the private network. Encryption is a common, but not inherent, part of a VPN connection.
VPN technology was developed to allow remote users and branches to access corporate applications and resources. To ensure security, the private network connection is established through a layered encrypted tunnel protocol, and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN.
In other applications, Internet users can secure their connections with a VPN to bypass geographic restrictions and censorship or to connect to proxy servers to protect personal identity and location to remain anonymous on the Internet.
However, some websites block access to known VPN technology to avoid circumventing its geographical restrictions, and many VPN providers have been developing strategies to overcome these obstacles.
A VPN is created by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunnel protocols over existing networks. A Virtual Private Network available on the public Internet can provide some of the benefits of a wide area network (WAN). From the user’s perspective, the resources available within the private network can be accessed remotely.
The first data networks allowed VPN-style connections to remote sites through dial-up modem or through rented line connections using virtual circuits X.25, Frame Relay and Asynchronous Transfer Mode (ATM) provided through proprietary networks and operated by telecommunications operators. These networks are not considered true VPNs because they passively protect the data that is transmitted by creating logical data streams.
They have been replaced by VPN based on IP and IP / Multi-Protocol Label Switching (MPLS) networks, due to significant cost reductions and greater bandwidth  provided by new technologies such as the digital subscriber line ( DSL) and fiber optic networks.
Virtual Private Network can be characterized as host to network or remote access by connecting a single computer to a network or as a site by site to connect two networks. In a corporate environment, remote access VPNs allow employees to access the company’s intranet from outside the office.
Site-to-site VPNs allow employees in geographically disparate offices to share the same virtual network. A VPN can also be used to interconnect two similar networks through a different intermediate network, such as two IPv6 networks connected through an IPv4 network.
VPN systems can be classified by:
The tunneling protocol used to tunnel traffic
The location of the tunnel termination point, for example, at the edge of the client or network provider
The type of connection topology, such as site to site or network to network
security levels provided
The OSI layer they present to the connection network, such as layer 2 circuits or layer 3 network connectivity.
VPNs cannot make online connections completely anonymous, but they can generally increase privacy and security. To prevent the disclosure of private information, Virtual Private Network generally only allow authenticated remote access through tunnel protocols and encryption techniques.
The VPN security model provides:
confidentiality so that even if network traffic is detected at the packet level (see network sniffer and deep packet inspection), an attacker would only see encrypted data
sender authentication to prevent unauthorized users from accessing the VPN
message integrity to detect any case of manipulation of transmitted messages.
Secure VPN protocols include the following:
Internet Protocol Security (IPsec) was initially developed by Internet Engineering Task Force (IETF) for IPv6, which was necessary in all IPv6 implementations that meet the standards before RFC 6434 made it only a recommendation.
This standards-based security protocol is also widely used with IPv4 and the Layer 2 Tunnel Protocol. Its design meets most of the security objectives: availability, integrity and confidentiality.
IPsec uses encryption, encapsulating an IP packet within an IPsec packet. Decapsulation occurs at the end of the tunnel, where the original IP packet is decrypted and forwarded to its intended destination.
Transport Layer Security (SSL / TLS) can tunnel the traffic of an entire network (as it does in the Open VPN project and the Soft Ether VPN project) or secure an individual connection. Several providers offer remote access VPN capabilities through SSL. An SSL VPN can connect from locations where IPsec has problems with network address translation and firewall rules.
Data gram Transport Layer Security (DTLS): used in Cisco Any Connect VPN and Open Connect Virtual Private Network to solve the problems that SSL / TLS has with TCP tunneling (TCP tunneling over TCP can cause large delays and connection abortions).
Microsoft point-to-point encryption (MPPE) works with the point-to-point tunnel protocol and in several compatible implementations on other platforms.
The Microsoft Secure Socket Tunnel Protocol (SSTP) tunnels into the Point-to-Point Protocol (PPP) or the Layer 2 Tunnel Protocol through an SSL 3.0 channel (SSTP was introduced in Windows Server 2008 and in Windows Vista Service Pack.
Virtual private multi-route network (MPVPN). Ragula Systems Development Company owns the registered trademark “MPVPN”. [eleven] VPN Secure Shell (SSH): OpenSSH offers Virtual Private Network tunnels (other than port forwarding) to secure remote connections to a network or links between networks.
The OpenSSH server provides a limited number of concurrent tunnels. The VPN function itself does not support personal authentication.
Tunnel endpoints must be authenticated before secure VPN tunnels can be established. Remote access VPNs created by the user can use passwords, biometric data, two-factor authentication or other cryptographic methods. Network to network tunnels often use passwords or digital certificates. They permanently store the key to allow the tunnel to be established automatically, without administrator intervention.
Virtual Private Network are more popular than ever today, but despite that, there are still many people who don’t know what that service can offer them. Well, in this article we will discuss the real benefits and disadvantages of VPN services, to make it easier for you to decide if they are right for you or not.
VPN services secure your online connections
WiFi is everywhere today, and it is extremely convenient to use, especially if you have a tight mobile data plan. The only problem with free Wi-Fi is that it is often not secure, which means that you are putting your personal data at risk every time you use them. After all, cyber criminals can discover a lot about you, which can lead them to steal your:
Credit card details
bank account details
Login credentials via email
However, if you use a VPN, you will not have to worry about those dangers. Why? Because a VPN uses encryption to secure its online communications, effectively ensuring that no one can monitor them. Basically, if a hacker tried to look at your connection traffic, he would only see gibberish.
This is also the reason why VPNs are also a good option to access work files remotely. If you ever need to verify a customer file while taking a break in a cafeteria and using your WiFi, your best option is to use a VPN to ensure that no possible hacker can compromise your connection and your work data.
A VPN can avoid bandwidth limitation
Haven’t you heard of bandwidth limitation yet? Basically it is when your ISP limits your bandwidth, effectively reducing your online speeds. They can do it regularly, or only once a week or month. Usually, ISPs do that to improve their services by getting rid of network congestion and making sure there is enough bandwidth for all users.
However, more often they participate in bandwidth limitation as a way to “convince” users (like you) to buy more expensive subscriptions and data plans.
Well, the good news is that, since a VPN encrypts all your Internet traffic, your ISP will not be able to see what you are doing online. They will not know if you are using “too much” bandwidth to play online games, download files or stream TV shows. Therefore, they cannot limit their bandwidth by doing any of those things.
VPNs can prevent firewalls
When you are at work, school, the airport or even in a hotel, you may have to deal with annoying network firewalls that prevent you from accessing certain websites. Network administrators do that because they often need to comply with various regulations, but that doesn’t do it just for you.
Fortunately, you can easily skip any firewall you encounter with a VPN, as it hides your IP address, the address to which the firewall restrictions have been applied.
And yes, a VPN would even allow you to avoid government-imposed firewalls (such as the Great Firewall of China, for example), so you won’t have to deal with any government censorship while browsing the Internet.
VPNs offer secure torrents
Torrents are not really dangerous if you know what you are doing, but they can jeopardize your privacy if you are not using a Virtual Private Network. You see, all Swarm members (all people who download and upload a torrent) can see their real IP address. That means you have unwanted strangers who can see what country and city it is from, and potentially find out what your zip code is and who your ISP is.
Also, don’t forget that torrents can be illegal according to the laws of your country. Using a VPN is a smart way to ensure that you don’t end up in legal problems, receive DMCA notices or that your ISP terminates your contract just by downloading a simple torrent.
VPNs improve online games
Because a VPN encrypts your connections and hides your IP address, there are many reasons to use that service to improve your gaming experience. You can play in any geographic region you want, you can play forbidden games, stay safe from DDoS attacks and you can even avoid unfair IP bans.
VPNs could help you avoid price discrimination online
Online retailers and airlines sometimes like to show different prices to their website visitors based on the geographic region they come from. They usually do it to better segment their markets and also to generate more profits. Of course, having to pay more money for the same product / service just because you are from a different part of the world is not fair.
As a Virtual Private Networks hides your IP address, it also masks your real geographic location. So, if you’re from a more developed country (like the U.S., for example), you might try to make it look like you’re from a less developed area of the world to get a better price.
