For starters, you may become a victim of cybercrime. Or hackers may harass your clients and tarnish your reputation in the process, which may ultimately lead to losing clients. Whereas if you invest in safeguarding privacy by implementing open source VPN software, you stand to gain a lot.  

Open source VPNs ensure that your virtual private remains private. 

 How does that happen? Well, when you do one of the following:

  1. When you get excellent open-source VPNs. Or,
  2. When you hire an IT guru to configure your VPN software.

Open source technology comes equipped with various encryption to ensure that your network remains private and secure. Some VPN systems are robust, and others are clunky and complex tools only a few people can use. So choose carefully. You have to ensure that whatever VPN system you pick is suitable for your business. 

In this blog post, we pin six different VPN solutions against each other and highlight some of their core features. Your job is to choose the best match for your business. 

But, before we dive in, let's clear this right away:

What is a VPN?

Are you one of the people who may be wondering what VPN stands for? Well, it stands for Virtual Private Network, a cybersecurity solution that helps businesses safeguard their privacy online. Put differently, VPN hides your IP address and encrypts your data so that third parties can't steal your data. This way, advertising agencies, security agencies, or even hackers can't track your activities online. Most VPN tools support Secure Sockets Layer protocol (SSLP), which helps them become more user-friendly and customizable.

Why do open source VPNs matter?

In the business environment, we're now embracing the importance of privacy the same way we appreciate transparency. We say privacy and transparency can coexist as long as one doesn't conceal the significance of another. And open source VPNs make that possible. 

Recently, it has become easy for unscrupulous businesses to access your data for advertising. Fortunately, there are open source VPNs that can prevent this.  

This point brings us to the next question: 

What is an open-source VPN?

The easiest way to define open source VPN is: open-source VPN is any free VPN system that anyone can modify, configure, and use. It comes with a wide range of functionalities that protects your virtual network. It uses a variety of encryption methods such as SSL/TLS to secure site-to-site information. 

A challenge about most open source VPNs is that it is not easy to configure yourself, and you will need an expert in networking knowledge or IT to help you out. For instance, the expert will set up a VPN by using a third-party VPN platform. 

Some key benefits of using open source VPN include:

  • You will get strong security - Your virtual network and site will be secure. 
  • You will get excellent community support - There are multitudes of developers working around the clock to improve an open-source VPN system. 
  • You can configure an open source - No scratch that...you can hire someone to configure it for you! 
  • Open source VPNs support forward secrecy - You know that confidential information is shared amongst a trusted circle of people. 
  • Most open-source VPNs are vetted - You know you will be using a perfect tool.

Conclusion

Without implementing VPN software, your privacy and that of your employees is at risk. Before you can say, "all my online activities are protected," you need a tool with the proper encryption protocols. It would be best to have a solution that secures the site-to-site information and the protocol SSL/TLS too. And if that tool is free, the better for your business. 

A compatible VPN like Tunnelblick can be a good start for anyone skeptical. The fact that it works well with macOS and OS X makes it a must-have. We all know that no brand values safety like Apple, right? While it is free and quick to configure, that doesn't mean anyone without technical know-how should try customizing it. 

"Who can I trust to configure my VPN?" You may ask. We wouldn't blame you for thinking that the same people responsible for implementing cybersecurity software may be cyber criminals. That's why you must do thorough background research when you hire an IT company to implement your VPN. Only employ a team of reputable experts that have a good reputation.

You may also ask, "How do I know if an IT company is reputable?" The easiest and quickest way to find out is by reading online reviews. Most good IT companies will have more good reviews than bad ones. Also, you need to make sure that you read all policies before signing up. Know which data you agree to share with them and for how long the contract will be. Remember, other VPN services companies may require that you pay a cancellation fee.
