A reliable Virtual Private Network (VPN) forms a primary component of a small and medium business’s security perimeter.
It’s like a safe tunnel between computers connected via the internet that allows them to access one another through a network.
Previously, mainly organizations utilized VPNs to link their remote branches or roaming employees with their office network. Now, VPNs have become essential for everyone, including consumers, due to increasing cyber-attacks these days.
Businesses with a good budget have already gone further into new-age technologies like zero trust.
But what about businesses with a low budget?
How do they ensure their security?
This is a big problem as they have limited resources.
According to a report, 43% of all cyberattacks target small-sized businesses, while 40% of SMBs experience around 8 hours of site downtimes due to cyber breaches.
Hence, SMBs need to secure their internet connection, digital assets, and company network by utilizing whatever resources they have. For this, VPN is the top gear they can include in their toolbox, a robust, efficient, and affordable solution.
So, if you are up to employing a VPN, you have two categories to choose from:
- A commercial VPN
- A free VPN service
Commercial VPNs are good with all their features and offerings, but they can cost you good money, which might not be affordable for many small businesses.
Hence, you can try an open-source or self-hosted VPN solution.
Pritunl
Pritunl offers an efficient VPN with complex gateway links and site-to-site links and allows remote users to access local networks. Safeguard the network traffic and users through secure encryption while they connect to public networks.
It is one of the best open-source alternatives to commercial VPNs. It can support thousands of users concurrently and get better control on your server without per-user pricing.

You can install Printunl on your Linux server or go for Vultr Cloud, which offers a 1-click setup.
Outline VPN
Managing VPN servers is tough unless you have something like Outline. This gives you two applications that work hand in hand, Outline Manager and Outline (Client), to effortlessly set up an on-premise or cloud VPN server and share encrypted connections.
Outline is built to evade DNS and IP-based blocking. One can start by downloading Outline Manager and picking up a preferred cloud provider or going in-house. This works with renowned cloud providers, including DigitalOcean, Google Cloud, AWS, Kamatera, etc.
Sharing a VPN connection is done with access keys which one can generate from the Outline Manager. Each such key is unique and gives control to the administrator over the connected users.
Outline Manager is available for Windows, MacOS, and Linux, whereas Outline Client (to use the VPN) has native Android, iOS, and desktop applications.
The best part? It’s open-source and free to use.

Let’s now look at the benefits of using a VPN and bonus tips on how to choose a VPN.
Benefits of using a VPN
One of the best ways of securing data in and out of your network could be using a VPN. It encrypts all the online traffic flowing between a VPN server and a smartphone or laptop to secure them.
It does so by masking your device identity and establishes a secure connection for you to browse online. Hence, it becomes tough for hackers to access your confidential data.
Let’s quickly look at some benefits of using VPNs.
Bypass location-based restrictions
VPNs bypass restrictions specific to a country, which is why you were not able to access some websites and databases available online previously. A VPN helps you access them online regardless of your location on this earth.
Reduces security risks
By using VPNs, all your network is safe from different sorts of online vulnerabilities. It also keeps your employees away from using public Wi-Fi, which further decreases the number of cyberattacks.
Maintain anonymity
Do you know a VPN can also protect your privacy?
Yes, that’s true.
You will be capable of browsing the internet while maintaining complete anonymity. It has the upper hand compared to web proxies or hideous IP software because VPNs allow accessing both websites and web applications privately.
Better performance and productivity
Implementing a VPN can also increase the efficiency and bandwidth of your network. This is why your workforce can complete tasks faster and achieve better productivity, no matter where they are working. In addition to this, the cost of maintaining a VPN is also very low.
Bonus Tip: things to consider while choosing a VPN
- Quality: Check out all the features it provides and cross them to meet your needs. If it matches, you can consider the VPN. Don’t pay for unnecessary features you are never going to use, as you have limited resources at hand.
- Compatibility: Most VPNs are compatible with major platforms like Windows, Android, Mac, iOS, and Linux, but others might not support all of them. In case you use a Windows PC but an iPhone, make sure the VPN you choose offers both platforms.
- The number of devices: Some VPNs support unlimited devices connected at once, but others might have limitations. Hence, consider your requirements as to how many devices you want to connect to and then choose a VPN.
- User-friendliness: If you are not a tech expert, it might be problematic for you to set up and use a VPN. Therefore, choose the one that you can handle easily. You can also find some VPNs that offer virtual setups, hence reducing all the heavy lifting.
- Affordability: Pricing is always one of the most crucial aspects for SMBs when buying some services. So, buy something that is a good blend of quality offerings and prices, like Namecheap FastVPN.
Final Words
VPNs are great for data security and necessary for a remote/hybrid work culture, especially if your business deals with sensitive data. You can use on-premise, self-hosting, or cloud VPN providers.
While a self-hosted VPN is the ultimate option for flexibility and control, it requires in-house management, which can become messy if your team lacks a networking expert.
In that case, the best option is going with cloud VPN services like NordLayer, GoodAccess, etc., for a complete hands-off deployment.
