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 farther into new-age technologies like zero-trust. But what about business 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.
What’s 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 find out some of the 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. 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. All the Pritunl codes are available publicly on Github, ensuring complete customization and transparency. As the configuration can be done via its web interface, it’s easy to manage everything.
Pritunl encrypts traffic between the server and clients for better security in addition to 2-step authentication with Google Authenticator. It supports clients from both WireGuard and OpenVPN, and it also uses IPsec for VPC peering and site-to-site links. VPC peering is available on AWS, GCP, and Oracle Cloud. It provides clear documentation, and the solution is scalable. Pritunl allows interconnecting and communication through MongoDB, faster service, and saves you from modifying firewalls. You can install Printunl on your Linux server or go for Vultr Cloud, which offers a 1-click setup.
OpenVPN
Access Server by OpenVPN is a renowned VPN solution designed to meet the challenges of SMBs. You can use it both on-premise or in the cloud and provide security to your entire business network. It is completely free to use with up to 2 VPN connections simultaneously. Manage it easily through its admin portal or CLI and control access by IP addresses, protocols, and ports. Access Server is available for multiple platforms, including iOS, Android, Windows, macOS, and Linux. You also get multiple modes of authentications such as 2FA, PAM, LDAP, and Active Directory. Other features included are comprehensive reporting with download, search, and view access logs in detail, along with the option to access the server cluster.
You can share the keys across different servers and scale your connections up/down quickly. OpenVPN’s Access Server allows site-to-site connectivity, protects remote desktop interactions, and screen sharing with strong access authentication and authorization. OpenVPN provides a layer-3 VPN using TLS/SSL with server and client certificates for mutual authentication and key exchange. Its servers are scalable to handle a maximum of 1500 connections concurrently, and you also get split-tunneling and full-tunneling options. The pricing model of Access Server is based on how many VPN connections you need at a time, which implies you will pay for your exact needs. If you want to play around with how OpenVPN works, you can get Kamatera VM for as low as $4 per month.
WireGuard
One of the prominent VPN software – WireGuard, is a simple yet extremely fast and new-age solution that leverages advanced cryptography. This general-purpose solution is designed for embedded interfaces as well as supercomputers alike. WireGuard is fit for different circumstances and was released initially for Linux kernel, but now it is deployable to other platforms, including Windows, BSD, macOS, etc. WireGuard is easy to configure and deploy, and the connection can be established by exchanging public keys simply.
It can even roam between different IP addresses, and you don’t need to worry about managing connections and the state. It uses advanced cryptography like Blake2, Noise protocol framework, HKDF, etc. WireGuard also includes Crypto key Routing that associates public keys using tunnel IP addresses. It also offers built-in roaming and allows you to create a WireGuard interface inside the primary network namespace having internet access.
Hamachi
Create VPNs on demand by using Hamachi by LogMeIn as your partner. This VPN hosting service allows you to quickly extend your network security to your distributed teams, remote workers, and mobile workers. Manage your virtual networks and restore them for end-users with simple clicks, no matter where you are located. Provision your client software easily and quickly to new systems without visiting the site. Run it in your network computer’s background to gain access anytime you need it. It is available in Premium, Standard, and multiple network subscriptions. Empower your remote users by providing them secure access to all your private network through a centralized gateway without tweaking your routers and firewalls.

Bonus Tip: things to consider while choosing a VPN
Quality: Check out all the features it provides and cross it with 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 which is a good blend of quality offerings and price.
Conclusion
If you are looking for a reliable and affordable way to secure your network and data, a good quality VPN is something you must consider. The above listed are self-hosted solutions, so get a cloud VM and play around to see what works for you.
