There are so many articles about VPNs, uses, and why we should use it, so I don’t say it again, just a post to share with people one more VPN service. The first point, which is also the one NordVPN boasts is the number of servers, they now own 5575 servers located in 59 countries, including in Vietnam. The server and its location are important because in theory, the closer a server is to our location, the faster the connection speed, and the more servers around us will increase the choice of connecting to a certain country. In addition to regular servers, NordVPN also has P2P support servers for those who need to share files.

The interface of the NordVPN app on platforms is quite simple and easy to use, both a world map in which the points marked are where NordVPN places servers, you can touch it to connect right away. Just below you’ll see the Quick Connect button, which functions as the fastest server connection for you. If your purpose is to use a VPN to use blocked services such as YouTube Music, Adobe, Netflix, websites … you shouldn’t use this button, you can choose directly where the country has the server, or look in the list just below it.

You can scroll down to select a country or type the find button, there are many countries for you to choose to connect to, in which the US owns the most locations, 15. If it is not necessary, it is advisable to choose a connection to countries near you to optimize the speed of your Internet connection.

In NordVPN’s settings on macOS, Windows, iOS or Android, there are features such as automatic reconnection (when starting the machine, when switching networks …), turning on CyberSec (ad blocking, malware, phishing, suspicious websites …). I tried it, I found CyberSec helps block ads or when opening a website very well, this feature is only available on Windows, macOS and iOS, Linux only. Kill Switch is a feature that ensures 100% you are safe, i.e. anonymous. Basically, the Kill Switch will turn on by default (Android alone, you go to the settings of the machine, choose a connection, choose a VPN to turn on), it will disconnect the Internet as soon as the connection to one of your VPN servers crashes, so we will be more assured when surfing the web.

In terms of price, NordVPN doesn’t offer plans with a limit on the number of connected devices like some of the services it’s used to, which it offers over the years, for example 1 year, 2 years, 3 years. NordVPN will allow you to connect up to 6 devices, enough for your personal needs. The app will be available on Windows, Linux, macOS, iOS and Android, as well as extensions for Chrome and Firefox browsers. You can even add it to your home router but you will need to go through a few steps, details see here.

ExpressVPN is the best VPN provider. This VPN offers the highest level of security and a large number of servers, spread across 94 countries. Despite its significantly higher costs than its competitors, ExpressVPN is still the no.1 choice for businesses that need a top-quality VPN solution.

Investing in ExpressVPN means you’ll get reliable and secure Internet access, good data security, and a variety of extensive customization options.

A VPN is a solution that keeps you anonymous on the internet by changing your ip address. The data is encrypted and transmitted in a virtual private network security tunnel. Because of such integrity and security authentication will give you a series of accompanying effects such as: Unblocking geography (access to blocked or censored websites). Work remotely safely, Buy international goods (air tickets, amazon …) cheaper in countries that enjoy promotions. Resist the monitoring of online monitoring organizations, security when using public wifi, increase safety when trading online. You can see “What is VPN? Pros and cons of VPN” for more detail

Let’s take a detailed review of ExpressVPN through the following article:

Plans and prices

Honestly, ExpressVPN is one of the most expensive VPN out there. Many plans are available, with the cheapest plan being a yearly subscription, which costs $8.32/month. Meanwhile, a 6-month subscription costs $9.99/month, while a monthly subscription costs $12.95/month.

Fortunately, all subscriptions give users access to every ExpressVPN server. An ExpressVPN account can support up to 5 devices. If you connect to your Internet router, you can provide private and secure Internet access to even more devices.

The features of ExpressVPN

With over 160 locations in 94 countries, ExpressVPN offers more options than most other VPN. With servers available on every continent except Antarctica, it’s easy to find one that fits your business needs.

ExpressVPN also ensures that most of its locations have multiple VPN protocols available. Whether OpenVPN UDP/TCP, IPsec, or IKEv2, ExpressVPN users can choose the VPN protocol that best suits their individual needs. Users can also ask the ExpressVPN app to automatically choose the most appropriate VPN protocol.

When using ExpressVPN, one of the favorite features is the Split-tunneling tool. Because using a VPN will definitely slow down Internet speeds, users may not want all apps to access the VPN simultaneously. The Split-tunneling tool allows users to choose which apps or websites will use a VPN, ensuring general browsing or media streaming continues at a faster pace. This feature is not available to most ExpressVPN competitors.

ExpressVPN also offers the best security in class. The use of both 256-bit AES encryption and a 4096-bit authentication key means that virtually no one can track your connection history and Internet usage.

Another advantage of ExpressVPN is using TrustedServer. This service allows ExpressVPN’s servers to run only on RAM and means that no identifying data is written on its servers, not even in encrypted form. Without a doubt, ExpressVPN is one of the most secure VPNs out there.

Interface and ease of use

The ExpressVPN app is easy to use and available on most devices, including game consoles and smart TVs. This makes this service different for competitors. As mentioned before, connecting ExpressVPN to an Internet router can also provide seamless VPN access for the entire office space or meeting room.

When using the app, changing the server is intuitive, and the app will always tell you when you’re connected or lose your VPN connection. If you suddenly lose your connection, the kill switch function ensures your Internet connection is blocked until the secure connection is reset.

The search function makes it easy to find servers, and the app will remember which servers you connect to most often (this recorded data does not leave your phone).

Support

While often ignored by developers and users, having a good support system is essential for any VPN. Thankfully, ExpressVPN offers both quality articles, which raise many of the issues customers may face, as well as a positive and useful 24/7 live chat feature.

ExpressVPN’s articles outline how to do exactly what you want – get straight to the point and there’s no clutter at all. However, if the problem persists, ExpressVPN live chat support is a reliable source that should be taken full advantage of. The answers usually come within minutes from friendly and knowledgeable consultants.

Conclusion

ExpressVPN is a no.1 VPN option: Top security, a wide range of the best server options in layering, and Split-tunnelling features. If you need a comprehensive VPN solution, ExpressVPN is a great choice (the high cost of this option is totally worth it).

However, if cost is a problem, then there are plenty of other quality VPN solutions available that will suit the needs of small and medium-sized businesses.

Disadvantage

• Cost more expensive than most competitors

What is a VPN?

VPN is a virtual private network, which is a network technology that helps create a secure network connection when participating in a public network such as the Internet or a private network owned by a service provider. Large corporations, educational institutions, and government agencies use VPN technology to allow remote users to securely connect to their own networks.

How to VPN works

VPN system can connect many different sites, based on region, geographical area … as the Wide Area Network (WAN) standard. Besides, VPN are also used to “diffuse”, expanding Intranet models to transmit information and data better. For example, schools have to use VPN to connect between campuses (or between branches and headquarters) together.

If you want to connect to a VPN system, each account must be authentic (Username and Password required). These account authentication information is used to grant access through 1 data – Personal Identification Number (PIN), which usually only works for a certain period of time (30 seconds or 1 minute).

When connecting a computer or another device such as a phone, tablet to a VPN, the computer works just like it is on the same in-network as the VPN. All traffic on the network is sent over a secure connection to the VPN. This helps you securely access in-house network resources even when you’re far away.

You can also use the Internet just like you’re in the location of a VPN, which offers some benefits of using public WiFi or accessing a blocked, geographically limited website.

When browsing with a VPN, the computer contacts the website through an encrypted VPN connection. All requests, information, data exchanged between you and the website will be transmitted in a secure connection. If you use a VPN in the UNITED States to access Netflix, Netflix will see your connection coming from the United States.

While it sounds pretty simple, in fact a VPN is used to do a lot of things:

• Access to a business network while away: VPN are often used by business people to access their business networks, including all resources on the local network, while on the road, traveling,… Resources in the in-network do not need to be in direct contact with the Internet, thereby increasing security.
• Access your home network, even if you’re not at home: You can set up your own VPN to access when you’re not at home. This will allow remote access to Windows through the Internet, using files shared in the in-network, playing computer games over the Internet just like being in the same LAN.
• Browse anonymously: If you are using public WiFi, browsing on non-https sites, the safety of data exchanged in the network will be vulnerable. If you want to hide your browsing activity so that the data is more secure then you should connect to a VPN. All information transmitted over the network will now be encrypted.
• Access to websites that are blocked from geography, bypass Internet censorship, bypass firewalls,…
• Download files: Downloading BitTorrent on a VPN will help speed up file downloads. This also helps with traffic that your ISP can get in the way of.

Protocols in VPN

VPN products often have a variety of convenience, efficiency, and security. If security is a top concern, then an organization needs to pay attention to the protocols that a VPN supports. Some widely used protocols have concerns, while others offer the most advanced security. The best protocols today are OpenVPN and IKEv2.

VPN protocols

The essence of a VPN protocol is a set of protocols. There are a number of functions that every VPN must solve:

Tunnelling: The basic function of a VPN is to distribute packets from one point to another without exposing them to anyone on the line. To do this, the VPN packages all the data in a format that both the client and the server understand. The data sender puts it in tunnelling format and the recipient extracts to get the information.

Encryption: Tunnelling does not provide protection. Anyone can extract the data. Data also needs to be encrypted on the line. The recipient will know how to decrypt data from a certain sender.

Authentication: For security, a VPN must confirm the identity of any client trying to “communicate” with it. The client needs to confirm that it has reached the correct intended server.

Session management: Once the user is authentic, the VPN needs to maintain the session so that the client can continue to “communicate” with it for a period of time.

Generally, VPN protocols treat tunneling, authentication, and session management as a package. Weaknesses in any function are potential security flaws in the protocol. Encryption is a specialization, it’s also very difficult, so instead of trying to create a new one, VPN often use a combination of multiple reliable encryption protocols. Here are the popular VPN protocols and their weak strength.

Weak protocols

Point-To-Point Tunneling Protocol (PPTP)

The oldest protocol still in use is the PPTP (Point-to-Point Tunneling Protocol). PPTP was first used in 1995. PPTP does not specify an encryption protocol but may use some protocols such as the powerful MPPE-128. The lack of strong protocol standardization is a risk, as it can only use the strongest encryption standard that both sides support. If one side only supports weaker standards, the connection must use weaker encryption than the user expected.

However, the real problem with PPTP is the authentication process. PPTP uses the MS-CHAP protocol, which can be easily cracked in the current period. An attacker can log on and impersonate an authorized user.

IP security (IPSec)

Used to secure communication, data streams in Internet environments (vpn external environments). This is the bottom line, the amount of traffic via IPSec is used mainly by Transport modes, or tunnels (or tunnels – this concept is often used in Proxy, SOCKS) to encrypt data in VPN.

L2TP

The L2TP protocol usually works with IPSec encryption algorithms. It is significantly stronger than PPTP but still worries users. The main vulnerability in L2TP/IPSec is the public key exchange method. The Diffie-Hellman public key exchange is a way for the two parties to agree on the next encryption key, and no one knows about it. There is a method that can “jailbreak” this process, which requires quite a large computing power, but then it allows access to all communication on a given VPN.

Secure Sockets Layer (SSL) and Transport Layer Security (TLS)

There is a similar section to IPSec, the two protocols above also use passwords to ensure safety between connections in the Internet environment.

In addition, the two protocols also use Handshake mode – which is related to the account authentication process between the client and the server. In order for a connection to be considered successful, this authentication process will use certificates – the account authentication keys are stored on both the server and the client.

Protocols with better security

IKEv2 (Internet Key Exchange)

IKEv2 (Internet Key Exchange) is rated highly security among current protocols. IKEv2 uses IPSec tunnelling and has a wide selection of encryption protocols. IKEv2 is used with AES-256 encryption so it is difficult to crack. IKEv2 uses powerful certificate-based authentication and can use the HMAC algorithm to verify the integrity of the data transmitted. IKEv2 supports fast and especially powerful communication in maintaining sessions, even when the Internet connection is interrupted. Windows, MacOS, iOS, and Android all support IKEv2. Some open source implementations are also available.

Version 1 of the protocol was introduced in 1998 and version 2 in 2005. IKEv2 is not one of the latest protocols, but is very well maintained.

SSTP (Secure Socket Tunneling Protocol)

SSTP (Secure Socket Tunneling Protocol) is a Microsoft product, supported mainly on Windows. When used with AES and SSL encryption, SSTP offers good security, theoretically. No SSTP vulnerabilities have been found at the moment but it is likely that a certain weakness persists.

A practical problem with SSTP is limited support on non-Windows systems.

OpenVPN

OpenVPN is an open set of protocols that offer powerful security features and have become very popular. OpenVPN was first released in 2001 under the GPL license. OpenVPN is open source, so vulnerability testing is guaranteed. OpenVPN’s encryption usually uses the OpenSSL library. OpenSSL supports many encryption algorithms, including AES.

There isn’t any support for OpenVPN at the operating system level, but many plans include their own OpenVPN clients.

Having the most security with a protocol requires administrators to handle it correctly. The OpenVPN community offers recommendations to enhance the security of OpenVPN.

SoftEther (Software Ethernet)

SoftEther (Software Ethernet) is a new name, first launched in 2014. Like OpenVPN, SoftEther also has open source. SoftEther supports the most powerful encryption protocols, including AES-256 and RSA 4096-bit. SoftEther offers greater communication speeds than most protocols, including OpenVPN, at a certain data rate. It does not support its own operating system but can be installed on many operating systems, including Windows, Mac, Android, iOS, Linux and Unix.

As a new protocol, SoftEther is not as supported as some other protocols. SoftEther doesn’t last long enough like OpenVPN, so users don’t have much time to test the weaknesses that may appear on this protocol. However, SoftEther is a heavyweight candidate for anyone who needs top-noted security quality.

So which protocol to choose?

The question “Which protocol is the safest?” is difficult to come up with an answer. IKEv2, OpenVPN, and SoftEther are all strong contenders. OpenVPN and SoftEther have the advantage of being open source. IKEv2 has open source implementations but also exclusive implementations. The main security advantage of IKEv2 is its ease of installation, reducing the risk of configuration errors. SoftEther offers very good security, but users do not have as much time to experience SoftEther as with the other two protocols, so it is very likely that SoftEther still has problems that users have not discovered.

OpenVPN’s code has been in place for years for security experts to test. OpenVPN is widely used and supports the strongest encryption protocols. Final decision-making also needs to consider other factors, such as convenience and speed, or whether security is of greatest concern.

Advantages and Disadvantages of VPN

The theory is that, when applied to reality, how vpn will have pros and cons. You are invited to continue discussions with Network Administrators.

To build a private network, a virtual personal network, using a VPN is an inexpensive solution. We can imagine this, the Internet environment is the main bridge and communication to transmit data, in terms of cost, it is completely reasonable compared to paying to establish a separate connection with high prices. Besides, it is not cheap to use software and hardware systems to support the account authentication process. Comparing the convenience that a VPN offers along with the cost of setting up your own system, it’s clear that a VPN is dominant.

But besides that, there are very noticeable disadvantages such as:

VPN do not have the ability to manage Quality of Service (QoS) over the Internet, so data packages – Data packages are still at risk of being lost and risky. The management ability of VPN providers is limited, no one can expect what can happen to their customers, or in short, get hacked.
