A Virtual Private Network (VPN) provides your business with a securely encrypted connection to your network over the public Internet. It provides you with an important piece of layered security that’s essential to protect your data. Using a VPN gives you the ability to remotely access important network resources and connect your company’s branches and locations worldwide.
So what is a VPN, exactly? Let’s find out.
The above diagram is a simplified example of a basic small business network. Laptops, tablets, and mobile devices have access from a wireless access point while hard-wired devices such as PCs, printers, and copiers, connect directly over a switch. While at the office, employees have internet access, as well as access to resources from network and database servers. The firewall prevents unsolicited, incoming traffic to the office’s private network. This ensures that the resources within the network are for internal company use only. When either employees or another network (e.g.: a branch office) are not physically in the same building, that’s where a business VPN comes in.
‘VPN’ has become a common term and even if we know the words it stands for, do we understand what it means? What does VPN stand for?
As mentioned above, VPN stands for Virtual Private Network.
Your business protects its data by storing it within your Private Network. This may be a server or computers on-premises, or you may pay for cloud-hosted services. For the importance of securing your data, the Network should be secured. Secured = Private.
When you use a VPN, you can extend that Private Network, making it Virtual. Remote workers, those at another branch office, vendors, etc. are able to securely connect to your network by using VPN connections. None of these connections are directly wired like the ones in the network diagram above, where cables run from your network switch to company devices. Nor are they close enough to your wireless access point to connect using WiFi. Instead, they utilize the Internet to connect to your network. This can be done safely, continuing to keep your data private, by encrypting those connections. Through a VPN, packets are sent over the Internet through an encrypted tunnel. This tunnel makes it appear as though you are directly connected to the private network.
The above diagram shows a basic network with a Remote Worker connected securely over an encrypted tunnel through OpenVPN Access Server. Once connected, the Remote Worker can securely access other devices, the database server, and the printer / copier, exactly as though they were in the office. The firewall is configured to allow incoming, secure connections to the VPN server destination. Now, the worker is virtually a part of the private network with access to internal resources.
OpenVPN Access Server supports endless configuration options. Businesses of all sizes use it to set up the exact access and granularity that they need for their company. While there are far too many options for us to show all the setups available, we can provide you with an overview of two common setups: Remote Access and Site-to-Site.
Connecting employees to the private network from various remote locations.
Grant and control access with your VPN server hosted on the private network
Securely connect with the VPN server using clients on user’s computers and mobile devices

Cloud computing might be the best new thing for small businesses. Your access to technology is simply a matter of choosing the right service contract. Many traditional desktop applications are disappearing as cloud adoption soars. For instance, accounting software vendors aren’t boxing up their product to place it on the shelves at office store chains anymore. Instead, a small business can purchase an online, subscription-based product based on the features that they need, scaling up or down accordingly.
|Cloud servers||On-premises servers|
|No capital expense||Service contract can become expensive||Low upfront costs for small businesses||Your network bandwidth determines VPN bandwidth|
|Only pay for what you need||Third-party involved||Critical data stored on-site||More prone to data loss in emergency situations|
|Easy to scale up or down as company grows and adjusts||May be complicated configuration for granular access control||Easy to grant access to on-premises data||No uptime guarantees|
|Data backed up regularly and consistent uptimes||Must be very aware of third-party security risks based on how vendor handles data||Low monthly or annual cost for licenses||Requires hardware, infrastructure, and IT support|
OpenVPN Access Server can be set up using cloud service providers, or on-premises with your own server. There are pros and cons of both, so it’s simply a matter of which option best fits your VPN needs.
OpenVPN Access Server can exist in the cloud by choosing your service provider and using our software solutions configured specifically for these marketplaces:
You can launch a virtual server and have it up and running with your own OpenVPN Access Server within minutes with this option. Why would you want to launch in the cloud? Perhaps you have your web server hosted with Amazon Web Services and want better control over access. You can add a new instance by launching OpenVPN Access Server from the AWS Marketplace and configure granular access.
Launching OpenVPN Access Server on your own Linux server is also a very cost-effective method that can provide your users with secure, remote access to on-site data. If you host your web server at your office, you could provide remote access to a web developer by setting up Access Server and creating a user profile for them.
Still wondering if your business should provide a VPN? Here are some more benefits to consider.
