NordVPN: An Overview Of What It Actually Is

NordVPN is a popular VPN provider service that helps keep you safe online. It is like a protective cover for your internet use. Many people choose NordVPN because it is good at protecting your privacy. The company started in 2012 and has become very famous since then. It offers many ways to keep the privacy of your online activities.

When you use NordVPN, it is a safe way to connect your internet connection. This path goes through special computers called servers. These servers are in many different countries. This helps hide where you really are when you are online.

NordVPN is compatible with many devices. It can be used on your computer, whether you are using a Windows PC or a Mac. It also works on phones and tablets that use Android or iOS. If you use Linux, NordVPN has a version for that too. You can even add NordVPN to your web browser. It has extensions for Chrome and Firefox.

NordVPN has more than 5,000 servers in 59 countries. This allows you to connect safely to the internet from nearly anywhere around the globe. Also, you can access the content, sites, apps, etc that is restricted in your region. 

In simple terms, NordVPN is a tool that helps keep your internet use private and secure, no matter where or what device you use.

What Is The NordVPN’s Encryption Standard?

AES-256 Encryption

NordVPN’s encryption standards have AES-256 encryption which is widely considered as the gold standard in data protection. AES is abbreviated for Advanced NordVPN’s encryption standards and 256 is the key size in bits. These NordVPN’s encryption standards method takes your data and scrambles it with a complex mathematical algorithm. The scrambled data can only be unscrambled with the correct 256-bit key.

When you connect to NordVPN, this encryption method conceals your internet traffic before it leaves your device. This encrypted data moves into the VPN tunnel to NordVPN’s servers. The servers decrypt the data and send it to its target location on the internet.

Advantages AES-256 Encryption

AES-256 encryption has various advantages than many other encryption methods. First and foremost, it is incredibly secure. The 256-bit key length means there are 2^256 possible combinations. This makes it practically impossible to crack using brute force methods with current technology.

Additionally, AES-256 is fast and efficient which means it encrypts and decrypts data with high speeds without slowing down your internet connection. It is also been thoroughly tested and vetted by cybersecurity experts and government agencies worldwide. Such things make it a trusted choice for protecting sensitive information.

Perfect Forward Secrecy (PFS)

Perfect Forward Secrecy is a feature that enhances the security of encrypted communications. With PFS a unique encryption key is created for every session separately. This means that if the key for one session is compromised, the security of previous or future sessions will not be affected.

NordVPN implements PFS across its network. When you connect to a NordVPN server, a new encryption key is generated for that specific session. As soon as your session ends, the key is also disposed of. If you reconnect later a completely new key will be used.

This implementation adds a layer of security to your VPN connection. Even if attackers were to obtain a session key, they would still be unable to decrypt your past or future internet traffic. It is like using a new and complex password every time you log in to a service.

What Protocols Does NordVPN Support?

VPN protocols are the sets of instructions and processes that determine how your data is routed through a VPN connection. NordVPN VPN protocols are very advanced and every protocol has strengths and use cases. The main NordVPN protocols supported by NordVPN are given as follows.

OpenVPN

• Features: OpenVPN is an open-source protocol and it has strong security and reliability features. It uses the OpenSSL library and TLS protocols to give a secure and safe VPN connection. OpenVPN is highly configurable which makes it adaptable to various network conditions and security requirements.
• Benefits: One of the main benefits of OpenVPN is that it is capable to bypass firewalls and network restrictions. It can be set up to run on any port which makes it hard for network administrators or ISPs to stop VPN traffic.

UDP vs. TCP Options

When using OpenVPN NordVPN allows users to select between UDP (User Datagram Protocol) and TCP (Transmission Control Protocol). UDP is generally faster but less reliable. So, it is ideal for streaming or gaming. While TCP is a bit slow but more reliable. It ensures that all data packets are received in the correct order. This makes TCP a better choice for activities where data protection is essential, such as browsing or downloading files.

IKEv2/IPsec

IKEv2 (Internet Key Exchange version 2) is combined with IPsec (Internet Protocol Security) to create a highly secure and fast VPN protocol. One of its main advantages is it can rapidly re-establish a VPN connection if it is lost for a short time. This makes IKEv2/IPsec particularly useful for mobile devices that may frequently switch between Wi-Fi and cellular networks.

IKEv2/IPsec uses strong cryptographic algorithms and perfect forward secrecy to ensure the security of VPN connections. It is also fairly lightweight which means it does not have a significant impact on device battery life. These features make IKEv2/IPsec a good balance of security and performance especially for mobile users.

NordLynx (WireGuard-based protocol)

NordLynx is one of NordVPN’s encryption standards which based on WireGuard. WireGuard is the latest VPN protocol that gives high speed and efficiency. NordLynx is made to provide the benefits of WireGuard while addressing some of its privacy concerns.

Differences From Other Protocols

• Speed Improvements: NordLynx is considerably faster than traditional VPN protocols. It uses simpler cryptographic algorithms and a more efficient code base. This results in faster connection times and higher speeds during use.
• Enhanced Security Measures: While WireGuard itself is considered very secure still it has some privacy limitations. NordLynx deals with these limitations by implementing a double NAT (Network Address Translation) system. This allows NordVPN to establish secure VPN connections without storing any identifiable user data on their servers.

How NordVPN Has Adapted WireGuard?

NordVPN has taken the core WireGuard protocol and added its own privacy-enhancing technology on top of it. The double NAT system ensures that the IP addresses of users are not stored on the VPN server. This maintains the balance between user privacy and the benefits of speed and security of WireGuard.

Benefits Over Other Traditional Protocols

NordLynx combines the speed of WireGuard with NordVPN’s proven commitment to privacy. Users can enjoy faster connections and improved performance without risking security or privacy. This makes NordLynx particularly suitable for activities that require both speed and security such as streaming high-quality video or large file transfers.

How Does NordVPN Protect Against Various Types Of Leaks?

DNS leak protection

DNS (Domain Name System) converts human-readable website names into such IP addresses that computers can easily interpret. Without proper protection, DNS requests can bypass the VPN tunnel. It can expose your internet activities to your Internet Service Provider (ISP) or any third parties.

NordVPN implements private DNS on its servers to prevent this. When you are connected to NordVPN, all your DNS requests are handled by NordVPN’s own DNS servers not your ISP’s.

How It Enhances Security                 

By routing all DNS requests through its own secure servers, NordVPN makes sure that your browsing history remains private. Your ISP can not see which websites you are visiting and websites can not see your real IP address. This private DNS implementation closes a common security hole in VPN services, providing more comprehensive protection for your online activities.

IPv6 Leak Prevention

IPv6 is the newest version of the Internet Protocol, created to replace the older IPv4. However, many VPNs struggle to properly handle IPv6 traffic, which can lead to leaks. NordVPN addresses this issue by completely disabling IPv6 traffic while you are connected to their service.

As more networks and websites adopt IPv6, preventing IPv6 leaks becomes very important. Without proper protection your device might send IPv6 requests outside the VPN tunnel. It can reveal your real IP address and location. By disabling IPv6, NordVPN ensures that all your traffic goes through the secure VPN tunnel, maintaining your privacy even on modern networks.

WebRTC Leak Handling

WebRTC (Web Real-Time Communication) is a technology that allows direct browser-to-browser communication for features like video chatting. However, it has the possibility that it can reveal your real IP address even when you are using a VPN.

NordVPN uses a multi-faceted way to prevent WebRTC leaks. Its apps include built-in protection against WebRTC leaks. Moreover, NordVPN provides browser extensions for Chrome and Firefox that can disable WebRTC entirely. It helps in ensuring that your real IP address stays hidden.

Advanced NordVPN Security Features

Kill Switch

A kill switch is an essential security feature that protects your data if your VPN connection drops suddenly. Without a kill switch, a VPN disconnection could expose your real IP address and unencrypted internet traffic. It can possibly risk your privacy and security.

NordVPN allows users to enable the kill switch feature automatically when the app starts or to manually activate it as needed. The automatic option is to make sure you are protected every time. While on the other hand the manual option gives you more control over when the kill switch is active.

1. System-wide Kill Switch

NordVPN’s system-wide kill switch works by monitoring your device’s connection to the VPN server. If for any reason the VPN connection drops the kill switch halts all internet traffic from your device immediately. This ensures that no data is transmitted outside the secure VPN tunnel. This protects your privacy until the VPN connection is redeveloped.

2. App-specific Kill Switch

In addition to the system-wide kill switch, NordVPN also offers an app-specific kill switch on some platforms. This feature allows you to choose specific apps that will be restricted from accessing the internet if the VPN connection collapses. This can be very helpful if you require VPN protection for some sensitive applications.

Double VPN

Double VPN is also known as multi-hop or cascading VPN. It is a feature that makes your internet traffic go through two VPN servers instead of one. This adds an extra layer of encryption and privacy to your connection.                                                                                                                                                                      

• Double Encryption Process: When using Double VPN, your data is encrypted on your device and then routed through the first VPN server. This server decrypts your data, re-encrypts it, and sends it to a second VPN server. The second server then decrypts the data again before sending it to its final point on the internet.
• Server Chaining: The two servers used in Double VPN are typically located in different countries. This makes it more and more hard for anyone to trace your internet activity back to your actual location.
• Benefits: Double VPN is particularly useful for users who want a top level of privacy and security. This could include journalists, political activists, or anyone accessing the internet from a country with strict online censorship.
• Impact On Connection Speed: While Double VPN provides enhanced security it can also drop the speed of your internet connection due to the additional encryption and decryption processes. Users should consider whether the extra security is worth the speed reduction for their specific needs.

Onion Over VPN

Onion Over VPN is a feature that combines NordVPN’s encryption standards with the anonymity of the Tor network. When you use this feature your traffic is first routed through a NordVPN server and then enters the Tor network.

• Multi-layer Encryption: By combining VPN encryption with Tor’s multiple layers of encryption, Onion Over VPN provides an extremely high level of privacy. Your data is protected by NordVPN’s encryption standards, which uses the three layers of encryption used by Tor.
• Anonymity Benefits: This feature makes it nearly impossible for anyone to trace your internet activity back to you. Even your VPN provider can not see your endpoint on the internet, as this information is hidden within the Tor network.
• Comparison With Standard Tor Usage: Onion Over VPN offers several advantages over using Tor alone. It hides your use of Tor from your ISP which can be important in some regions where using Tor is monitored or restricted. It also protects you from malicious Tor exit nodes as your traffic is encrypted by NordVPN before entering the Tor network.

CyberSec

CyberSec is NordVPN’s built-in security suite created to protect users from several online threats. It poses as a shield against malware, phishing attempts, and intrusive ads.

Malware Protection

• Inhibiting malicious websites: CyberSec maintains a real-time list of restricted known malicious websites. If you attempt to access a site on this list, CyberSec will hold off the connection, protecting you from potential malware infections.
• Preventing malware downloads: In addition to hampering malicious websites, CyberSec can also prevent the download of files known to contain malware. This adds an extra layer of protection against accidentally downloading harmful software.
• Phishing Protection Mechanisms: CyberSec also protects against phishing attempts by halting access to known phishing websites. These are websites specifically designed to deceive you into disclosing sensitive information such as passwords or credit card details.
• Ad-Bunging Capabilities: CyberSec includes a comprehensive ad stopper that can remove various types of online advertisements including pop-ups, auto-play video ads, and banner ads.

By stopping ads, CyberSec can improve your browsing experience significantly. Web pages load faster, you use less data, and you are less likely to be distracted by intrusive advertisements. However, some users might choose to disable this feature on sites they want to support through ad revenue.

The Role Of Server Network In NordVPN’s Security

RAM-only Servers

NordVPN uses special servers called RAM-only servers. These servers are different from normal computers. They do not have hard drives to store information. Instead, they use something called RAM, which is like a computer’s short-term memory.

These RAM-only servers are good for keeping your information safe. When you turn off a computer with RAM, all its information goes away. So, if someone tries to steal one of NordVPN’s servers, they will not find any information about the people who use NordVPN.

Server Locations And Diversity

NordVPN has many servers in lots of different countries. This means you can connect to the internet from many different places. It helps you get around restrictions that some websites put up based on where you are.

Having servers in many places also means that NordVPN works fast. Even when many people are using it simultaneously, you can still connect quickly. It is like having many roads to get to the same place – if one is busy, you can take another.

Obfuscated Servers For Restricted Regions

Some countries try to stop people from using VPNs. NordVPN has a clever way to help with this. They have special servers called obfuscated servers. These servers make your VPN connection look like normal internet traffic.

It is like putting a disguise on your internet connection. This makes it difficult for people who are watching to know you are using a VPN. It helps people in countries with strict internet rules to use the internet more freely.

Some Additional Privacy And Security Measures

Multi-factor Authentication

NordVPN implements multi-factor authentication (MFA) for account logins. An extra layer of security is added to user accounts with multi-factor authentication. It requires a second form of verification such as a code that is sent to your phone with your password. MFA also reduces the risk of illicit access to your VPN account.
