VPN Protocols

Protocols have various characteristics that benefit VPN users, depending on the situation. Some may focus on privacy, while others may prioritise speed. Depending on the device, what you want to do, and how you want to do it, VPNs use different protocols.

If you’re at home watching Netflix, choosing a VPN protocol with fewer security protections to speed up your internet connection won’t hurt. Instead of waiting for your favourite TV show to load, you may spend more time immersed in it. The opposite is true when you’re doing things online that put your data at risk, such as shopping or banking on an unprotected network.

When looking at VPN software, most of them will inform you which VPN protocols they support. Knowing the ins and outs of the many types of VPN protocols is necessary to properly comprehend what this implies and how it could affect how you browse the web.

What Are the Types of VPN Protocols Available?

Here’s a rundown of the most prevalent VPN protocols:

What Are the Types of VPN Protocols Available? Here's a rundown of the most prevalent VPN protocols:

  • OpenVPN

The most widely used VPN protocol. For private key exchange, OpenVPN employs TLS with TLS/SSL. It uses the OpenSSL kind of crypto library, a collection of well-protected cryptography techniques that will allow you to get more secure.

OpenVPN employs two different types of network protocols:

User Datagram Protocol – requires fewer details in verifying data and is thus faster.

Transmission Control Protocol) – it necessitates repeated data verifications and reduces the pace of the data exchange procedure. This ensures reliable connectivity and is ideal for connecting to remote systems.

  • IKEv2

On VPN mobile apps, Internet Key Exchange (IKEv2), the second version is fairly widespread. The rationale for this is that one will be automatically rejoined if your VPN server connection is lost. This makes switching between mobile data and wifi almost smooth. The protocol also supports advanced cryptography functions. It can be encrypted using 3DES or AES, with the latter being the best and safest option.

  • L2TP/IPSec

Because this Protocol lacks encryption, it relies on the IPSec – Internet Protocol Security with the 256-bit AES form. L2TP is in charge of tunnelling and authentication. Layer 2 Tunneling Protocol is a hybrid of two previous protocols: Point to Point Tunneling Protocol and Layer 2 Forwarding Protocol. L2TP protocol is regarded as secure. However, there is one concern: IPSec/L2TP was co-established with the National Security Agency, and there happens to be a concern that L2TP/IPSec communication may contain backdoors.

  • WireGuard

WireGuard, a recent major tunnelling system, provides the fastest connections while preserving security. WireGuard protocol addresses issues with OpenVPN and IPSec implementations, which are notoriously complex and susceptible to misconfigurations. Wireguard contains a small number of coding lines, making it simple to patch or implement.

WireGuard leverages available cryptography packages for data authentication and encryption, such as Poly1305 and ChaCha20. Developers can use WireGuard’s tools to add their scripts and extensions.

  • SSTP

This protocol is a hybrid of the L2TP and PPTP protocols. It uses the SSL channel (3.0) to send PPTP or L2TP traffic. This feature enables data integrity encryption. It also utilizes normal TCP and SSL port 443, allowing you to get over most firewalls. It also explains that the data exchanged can be not supervised and operate around restricted ports and other network administrator constraints.

What Are the Benefits of VPN Protocols?

  • Secures Your Network

There are several benefits attached to using a VPN. However, a crucial benefit is that firms can safeguard networks efficiently. A website or program can effectively track users’ internet operations without awareness. Hackers can effectively evaluate information gathered and come at you directly via advertisements. Without VPN, you can get several adverts, which can be disturbing and bad for your browsing experience.

Software, web browsers and people cannot get access to your internet connection if you utilise a VPN. This makes sure that the data you receive and provide is anonymous and secure.

  • Secure Your Personal Data

Another major advantage of a VPN is the ability to disguise your data. Hackers are capable of intercepting vital information you enter on websites utilizing various methods. They can utilize that data to effectively impersonate identity and access credit card details, bank accounts, and other vital data. High-level types of security like 256-bit encryption are capable and readily available for use with a VPN. Hackers who can intercept your chats online will see them as meaningless, garbled characters and texts.

  • Stop Data Throttling

Data throttling happens when one has exhausted all of your available data, and the internet service provider decides to reduce the pace of your connection. If you utilize a VPN, you’ll discover that a perk of using a VPN is simply the ability of the network to evade data caps since neither your ISP nor you can see your data usage. This might be particularly useful for employees expected to utilise different data plans on their smart gadgets to surf the internet while on the road.

  • Access Geo-restricted Services

You can get a different (IP) address by utilizing a VPN. When a device surfs the internet and engages in other activities online, its IP indicates where it is. Parts services and websites refuse to let users from particular countries access a part or all of their content. This benefit is typical of streaming services that cater to certain geographical areas.

Some business websites also effectively restrict using their public work services based on your location, like requesting quotations or seeing more information about their services. You can make it appear as though you are checking through the internet from a GPS location acceptable to the network service you are looking to access by utilising a VPN.

Proprietary VPN Protocols, What Makes them Special?

Some of the greatest VPN companies have their proprietary protocols. ExpressVPN created Lightway, NordVPN’s protocol is NordLynx, and Hotspot Shield’s solution is dubbed Catapult Hydra.

These are usually quick and secure (NordLynx is a modified version of WireGuard, which we described earlier), but there are drawbacks. Although Lightway is open source, NordLynx and Catapult Hydra are not, making it impossible for professionals to test their functionality. Other providers and device makers do not accept these proprietary protocols because they are proprietary. Only the provider’s apps and hardware are supported.

Picking the Best VPN Protocols for Various Applications

Although it may be tempting to label Wireguard as the finest tunnelling protocol, the main reality may be more complicated. Also, you should understand that not all devices will fully support all of the available protocols (important if you’re not utilising VPN software). It’s useful to know what protocols to utilise in various scenarios in such situations.

  • Streaming

When it comes to streaming video, you’re more inclined to prioritise speed above privacy. The VPNs are frequently used to circumvent geo-blocking; if you’re using one, you’re probably less concerned about the cops showing up at your house because you saw a TV show on Hulu. You should use NordVPN’s NordLynx. This is based on Wireguard for the greatest performance. WireGuard alone will suffice, and L2TP/IPSec, IKEv2, or even OpenVPN operating in UDP mode are viable options.

  • Downloads

If you are looking to download a stream of data through P2P networks, you will need to balance speed and privacy. Because BitTorrent is transparent, downloaded torrents reveal your IP address. Copyright holders and hackers will find you a vulnerable target. As a result, you should choose safe and fast protocol versions like Wireguard or OpenVPN operating in UDP mode.

  • Privacy

Assume you’re a whistleblower or working in a country with severe regulations. The connection’s privacy and security should be your main priorities in that situation. As a result, you should only use the safest protocols, such as Wireguard and OpenVPN. You should also look for a VPN that includes a “stealth mode” bypassing firewalls.

Frequently Asked Questions

One should select VPN protocols based on needs. Not every VPN service provider will support all VPN protocols. Based on your operating system and other constraints, you should try to discover the right option realistically. OpenVPN, IKEv2, and WireGuard are reliable modern VPN protocols.

Although Wireguard happens to be an advanced tunnelling protocol, the most secure options include OpenVPN and IKEv2.

The fastest kind of VPN protocol is WireGuard. It has fast speeds even on older devices. NordVPN represents one of the top VPN companies, with a unique WireGuard implementation likely the quickest.

When using a VPN, the reduction of speed is determined by various factors, including your distance from the server, the VPN protocol, location, load on the server, etc. Under normal circumstances, you might expect a 50 per cent reduction in speed.
