What Is A VPN?
A Virtual Private Network (VPN) provides your business with a securely encrypted internet connection to your private network over the public internet. VPN protection is an important piece of a layered security protocol that’s essential to protecting company data as well as an employee's personal data. Using a VPN service gives you the ability to remotely access important network resources and connect your company’s branches and locations worldwide.
Need a business VPN?
Another benefit of using a VPN provider is that a VPN prevents your internet service provider (ISP) from logging websites you visit — it encrypts your internet traffic so your ISP doesn't know where or what you're browsing. (or, to put it another way, it keeps your ISP from snooping on your private internet activity.) Your ISP will only know when you connect to a VPN server's Internet Protocol address (IP address) and the amount of bandwidth used. It's important to note that not all internet service providers can detect VPN use. Check your internet service provider’s privacy policies to understand what they can and cannot see.
So what is a VPN, exactly? Let’s find out.
The above diagram is a simplified example of a basic small business local network. Mobile devices use a wireless access point for access. Hard-wired devices such as PCs, printers, and copiers, connect directly over a switch. On-site employees have internet access, as well as access to resources from network and database servers. Unauthorized incoming traffic is blocked by the firewall. This limits network resources to internal use. When employees use another network (e.g., a branch office, public WiFi hotspots) not physically in the same building, that’s where a business VPN comes in.
What does VPN stand for?
"VPN" is a commonly used term, but even if we know the words it stands for, do we understand what it means?
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. Or, to put it another way, if your network isn’t secured, the data that lives on it isn’t secure, either.
When you use a secure VPN, you can extend that private Network, making it virtual. Remote workers, those at another branch office, vendors, etc. are then able to securely connect to your network by using VPN connections while maintaining online privacy. 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 Wi-Fi. Instead, they utilize the Internet -- often public WiFi networks -- to connect to your network. This can be done safely, continuing to keep your online activity private, with encrypted connections. Through a VPN, packets are sent over the internet through an encrypted tunnel. This encrypted VPN tunnel makes it appear as though you are directly connected to the private network, keeping your online activity (including your browsing history) hidden.
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 use an internet connection to 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.
How a VPN Works
A VPN connection secures your internet connection when you work off-site (e.g., coffee shop, hotel, airport, or even a different country). It routes all of your network traffic through an encrypted tunnel via the VPN. Routing the network traffic disguises your IP address when using the internet, replacing it with the location and an IP address from the VPN server making its location invisible. A VPN connection also secures against external breaches.
Two common types of business VPN setups:
OpenVPN products support endless configuration options. Businesses of all sizes use OpenVPN Cloud or OpenVPN Access Server 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.
VPN Client Apps
Securely connect with the secure VPN server using clients (a.k.a. vpn app) on user computers and mobile devices. Business VPNs should support a variety of operating systems (Microsoft Windows, Mac, iOS, Android, Linux).
Connecting multiple, fixed sites (branches, offices, etc.) over a public network.
Connecting remote and main offices.
Connecting partners or customers with the main office.

The difference between cloud and on-premises VPN setups:
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. 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.
Pros and cons of cloud and on-premises servers:
|Low upfront costs for small businesses||Your network bandwidth determines VPN bandwidth|
|Critical data stored on-site||More prone to data loss in emergency situations|
|Easy to grant access to on-premises data||No uptime guarantees|
|Low monthly or annual cost for licenses||Requires hardware, infrastructure, and IT support|
|No Capital Expense||Service contract can become expensive|
|Only pay for what you need||Third-party involved|
|Easy to scale up or down as company grows and adjusts||May be complicated configuration for granular access control|
|Data backed up regularly and consistent uptimes||Must be very aware of third-party security risks based on how vendor handles data|
What is a VPN in the cloud?
Those are the pros and cons of cloud and on-prem VPNs, but what exactly is OpenVPN Cloud?

What are VPN protocols?
There are five types of VPN protocols:
- Point-to-Point Tunneling Protocol (PPTP)
- Layer 2 Tunnel Protocol (L2TP/IPSec)
- Secure Socket Tunneling Protocol (SSTP)
- Internet Key Exchange version 2 (IKEv2)
Each protocol has unique specifications based on priorities (e.g., throughput speed, masking/encryption) that dictate how data is routed through a connection.
Benefits of Business VPN Services
Still not sure if your business should provide a VPN? Here are some more benefits to consider.
With a VPN service you can:
