Why is it important to use a VPN, and how it improve your online experience and security?

Exploring the benefits of VPN use and knowing the different types of VPNs

In our increasingly digital world, queries such as “Do I need a VPN?” and “Why should I use a VPN at home?” are becoming more common. These concerns develop when internet users become more conscious of their privacy and surfing security. Governments, marketers, and hackers may attempt to track your web surfing history. Without a virtual private network (VPN), your internet service provider (ISP) may monitor your online activities and sell it to the highest bidder. You may, however, use a VPN to secure your internet traffic whether surfing at home, work, or on a public network. Read the article to find out why you need a VPN.

Remote Access VPN

A remote access VPN establishes a temporary encrypted connection between the business’s data centre and the user’s device. It becomes operational only once the user activates it. Otherwise, it lacks a permanent link. Businesses generally utilise this kind to securely access programmes and data stored in a central hub over a VPN connection. Think of it as a VPN connection that creates a safe conduit from your device to important papers or corporate data on the other end.

The biggest disadvantage of this strategy is that the programmes you use are no longer often hosted from the main headquarters. Most businesses use software as a service (SaaS) solutions, which are universally hosted someplace else and utilise massive data centres. since a result, setting up a remote access VPN may not be the most practical approach, since data would be routed from the user’s device to the central hub, then to the data centre, and back. Not only might this cause major bottlenecks and decrease network performance.

However, this option might be useful when you require it for specialised self-hosted apps or highly secret information that you do not wish to host elsewhere. However, it is important to prepare based on the amount of people who will be accessing them. The more of them you’ll have, the more capable hardware you’ll need.

Site-to-site VPN

Site-to-site VPN is a persistent link between numerous offices that forms a single network that is constantly active. It requires separate configuration for each networks and is best suited for scenarios when you have many distant sites. It may be used to configure on-premises routers or firewalls.

If your users desire to login from home, this approach will not be very useful. Administrators frequently do not accept connections from networks over which they have no control for safety concerns. Essentially, they’re giving up accessibility in favour of security.

On the upside, it’s one of the cheapest ways to combine many networks into a single intranet. Every device may behave as if it is connected to the same local area network, allowing for data transfers and preventing outside surveillance efforts.

Most common VPN protocols

VPNs use tunnelling protocols, which serve as guidelines for data transmission. It includes thorough instructions for packing the data and performing the necessary checks when it arrives at its destination. These varied strategies have a direct impact on process speed and security. These are the most popular ones.

Internet Protocol Security (IPSec)

IPSec is a VPN tunnelling technology that protects data flow by requiring session authentication and packet encryption. It is a two-step encryption process: the encrypted message is embedded in a data packet that is then encrypted again. Because of its great compatibility, the IPSec protocol is commonly used in Site-to-Site VPN configurations. It is combined with additional protocols for increased security.

Layer 2 Tunneling Protocol (L2TP)

L2TP creates a secure tunnel between two L2TP connection locations. Once established, it encrypts the transferred data using an extra tunnelling mechanism called IPSec. L2TP’s complicated design contributes to the excellent security of shared data. It’s another common option for site-to-site configurations, particularly when more security is required.

Point–to–Point Tunneling Protocol (PPTP)

PPTP, another tunnelling protocol, uses a PPTP cypher to construct a tunnel. However, since the cipher’s inception in the 1990s, processing power has grown dramatically. Brute-forcing the cypher would not take long to crack, revealing the transferred data. As a result, this cypher is rarely used in technology; instead, more secure tunnelling protocols with more sophisticated encryption are used.


The Secure Socket Layer and Transport Layer Security protocols are the same standard for encrypting HTTPS web pages. That manner, the web browser serves as the client, and user access is restricted to certain programmes rather than the entire network. Almost all browsers have SSL and TLS connections, therefore, no additional software is normally required. Typically, remote access VPNs employ SSL/TLS.


OpenVPN is an open-source version of the SSL/TLS foundation that includes extra cryptographic techniques to make your encrypted connection even more secure. It’s the preferred tunnelling protocol because of its great security and efficiency. However, compatibility and configuration might be hit or miss because it cannot be installed natively on many devices to create router-to-router VPN networks. Therefore, the performance may vary.

It is available in both User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) variants. UDP is quicker because it utilises fewer data checks, whereas TCP is slower but better at protecting data integrity. OpenVPN is a well-rounded and secure tunnelling protocol that is widely used for both remote access and site-to-site virtual private network applications.

Secure Shell (SSH)

SSH, like the other choice, establishes an encrypted connection and permits port forwarding to distant machines over a secure channel. It’s great for viewing your business desktop from your laptop at home. While SSH channels allow more flexibility, they should always be closely monitored because they serve as a direct entrance point for breaches. That is why it is best suited to remote access setups.


The most recent publicly accessible tunnelling protocol is less difficult but significantly more efficient and secure than IPSec and OpenVPN. It uses extremely simplified code to get the greatest possible speed with a small margin of error. While it is still in its early stages of adoption, you may be able to identify offices that use Wireguard for site-to-site connections. There are also proprietary WireGuard implementations, such as NordLynx.

Do I need to use a VPN?

Yes, you require a VPN to protect your online activities, conceal your IP addresses, and safeguard your data. A VPN should be the foundation of your internet privacy and security, whether at home, business, or in public.

A VPN’s objective is to hide your IP address and route your browsing data over an encrypted tunnel, preventing third parties from monitoring your online behaviour. It protects customers from potential cyber dangers, enabling them to evade internet restrictions, avoid ISP throttling, and safely access home material when travelling.

You can learn more about VPNs and how they operate.

Who uses a VPN service, and why?

VPNs are used by individuals and organisations for a variety of objectives.

General client. VPNs are used by regular internet users to increase privacy and prevent ISPs from monitoring and restricting bandwidth depending on behaviour. A VPN is required to secure private data from hackers, particularly while connecting to public hotspots. In addition, it allows users to safely access home material when travelling.

Companies and organisations. VPNs are used by businesses to enable remote access. They contribute to the security of corporate networks for workers who work remotely or travel. Furthermore, using a VPN might assist businesses in protecting their sensitive data from cyber threats.
Journalists and advocates. These individuals frequently labour in dangerous circumstances, which limit press and expression freedom. VPNs enable people to view banned content while masking their location.

Travellers. People who travel overseas use VPNs to securely access material or services from their home country, which may not be available in other countries. They aid in the protection of web traffic when using insecure internet Wi-Fi connections.
Students. Educational institutions typically limit access to internal networks, so a VPN can enable students circumvent restrictive network regulations and access academic materials from off-campus.

Individuals that like gaming. If the game provider allows it, VPNs allow gamers to connect to gaming servers in other areas. They can also help to avoid future DDoS assaults and minimise slowness in some circumstances.
Even while a VPN is a common cybersecurity tool in these situations, it is not infallible. Even with a VPN, certain advanced monitoring methods can allow criminals to monitor your online behaviour.

Why do I need to use a VPN at home?

A VPN’s primary goal is security and privacy, but there are several additional advantages and disadvantages to utilising one. Here are some of the most important reasons why you should have a VPN connection at home:

For secure home network.

While many people feel their home Wi-Fi is inherently safe, weaknesses can expose devices and personal data to cyber dangers, such as untrustworthy neighbours trying to access your Wi-Fi.

A VPN can also keep your smart gadgets safe. For example, an unguarded webcam is a gold mine for a cybercriminal. Other Internet of Things (IoT) devices, such as robot vacuum cleaners, doorbells and appliances, may also be exposed if your home network is not secure.

Using a VPN at home or on your router might make it far more difficult for hackers to obtain your personal information. Even if they use man-in-the-middle (someone could be watching every move you make online. In these attacks, hackers spy on your browsing activity and wait for the perfect time to strike. For example, they position themselves between you and the site you’re trying to engage with and manipulate the flow of information) attacks to target your device, they will be unable to access your internet traffic.

For a private and smooth connection

Unprotected communication might serve as an opportunity for future hackers. A VPN makes it more difficult for hackers to intercept your web traffic and steal your important data or identity. This is especially crucial if you undertake sensitive transactions or handle personal information at home.

A VPN connection also works as a digital shield against internet service providers monitoring your online behaviour. They may track your internet behaviour, thus a VPN can help you protect yourself from eavesdropping. Additionally, ISPs may limit particular forms of traffic, such as video streaming or gaming, in order to prioritise other types of traffic. As a result, utilising a VPN might help you avoid ISP traffic-based bandwidth limiting.

Furthermore, a VPN may serve as an ad blocker, protecting you from intrusive and unwanted ads. This may allow you to speed up loading times, minimise data use, and conserve mobile data.

For remote access to a home network

Another reason to utilise a VPN is while travelling. If you travel or are frequently away from home, you may use a VPN to securely access files or systems on your home network from any location in the globe, as long as you have an internet connection. Meshnet and other remote access tools can enable you access files on your home computer or utilise services that are only available through your home network.

Furthermore, if you use remote desktop software to access your home computer from another place, a VPN may provide a secure and encrypted connection, shielding you from any risks.

We strongly advise utilising a VPN at home and elsewhere for all of the reasons stated above.

Do I need a VPN on my phone?

Yes, a VPN on your phone may improve phone security and enable safe browsing. Consider how frequently mobile phones are connected to public Wi-Fi networks in cafés, airports, and hotels. Because these Wi-Fi networks are frequently insecure and vulnerable to hackers, you’re better off using a VPN.

What other devices should I use a VPN for?

In addition to utilising a VPN on a computer and smartphone, other home gadgets may require VPN security. Portable tablets, for example, connect to several networks and hence require the same level of security. Smart TVs, which are frequently used for global streaming services, might benefit from VPNs to safely transmit your favourite shows.

A VPN can let you encrypt personal data and connect to worldwide game servers via gaming consoles. Without a VPN, unprotected IoT devices such as smart thermostats and baby monitors are vulnerable to assaults. Remember that any device that connects to the internet and sends data can benefit from the increased data privacy and online security that a VPN provides.

How to choose the right VPN

To choose the best VPN, you must first determine your preferences. Even while each use case necessitates a unique VPN configuration, the guideline stays the same: choose a VPN that balances privacy, security, speed, and usability. To choose the best solution, use the following tips:

Select a reputable VPN provider. Choose a safe VPN service with reliable user reviews that invest in product development and maintenance.
Look for a VPN service that does not keep any logs. Examine a VPN provider’s privacy policy and search for one that does not track the user’s surfing habits.

Check that the VPN you choose is compatible with your devices. Check that the VPN works with all of your devices and platforms, including Windows, macOS, Android, iOS, Linux, and routers.
Look for a variety of servers. Make sure a VPN service provider has a large number of VPN servers, giving you additional virtual locations to select from.
Select a fast VPN. Choose VPN providers that will not dramatically impact your connection speed. NordVPN uses the NordLynx protocol, resulting in the fastest VPN accessible.

Ensure that you will receive assistance. Purchase a VPN with 24/7 customer assistance to assist you if any technical difficulties emerge.
Take great note of the pricing. Never rely on free VPNs since most of them make money by gathering and utilising your private data for marketing purposes or selling it to other parties.

So, whether you often connect to public Wi-Fi, conduct important transactions, or want to safely view your favourite shows, a VPN is a must-have. It provides an additional degree of protection for your online traffic. Aside from the reasons listed above, you may use a VPN for a variety of purposes, such as saving money on flights and rentals or ensuring safe downloads. Check it out!
