What Is a VPN?
Virtual Private Networks (VPNs) are a way to secure remote network access to cloud-based and on-premises resources. VPNs offer policy-based and segmented access to a private network, which shields sensitive resources from the internet. Employees can log in and communicate securely to others in the company.
For those working remotely, a VPN is a way for them to continue to have secure access to corporate intranets and databases. But they must properly complete authentication procedures to do so.
Another use case for VPNs is in site-to-site links between the head office and its branch offices or partner sites. Again, authentication is everything. These links must only be available to authorized users.
As such, VPNs are available via on-premises hardware and software, as on-premises software-only applications, or via the cloud. They should be able to accommodate a wide variety of devices, while also providing WiFi connections to enterprise data, sales systems, and other company applications.
Once authorized, users utilize an encrypted tunnel to connect and communicate. Other layers of protection include site-to-site internet protocol security (IPsec) to establish, as well as various access controls and access policies.

How to Choose a VPN
When selecting a VPN tool or vendor, it is vital to ensure the appropriate levels of security are present. IPsec tunneling, encryption support such as AES-256, 3DES-168, and access controls are essential elements.
Another selection criterion is latency. If employees are waiting several minutes for a connection, or if it takes forever for pages to load and attachments to upload/download, personnel will drift away from the VPN and use a less secure public internet connections instead. Latency, therefore, must be kept to a minimum.
Explore Integration Options
Whatever VPN is chosen, it should easily integrate with any cloud platforms or corporate applications. Incompatibilities with popular products in heavy use in the enterprise like Salesforce, Amazon Web Services, Microsoft Azure, or Google applications should be avoided.
Choose the Right Level of Support
Other factors are scale and support. Some organizations need basic VPN services and minimal support. Others need a raft of enterprise features and top-notch support. It is a case of matching these features to the vendor. Otherwise, you could either overpay for features you don’t need, or be left with a corporate VPN that is grossly inadequate.
Avoid Consumer Solutions
Differentiate, too, between consumer-grade VPN services and business VPN services. The consumer class is cheaper, but offers limited features. All they do is hide the user IP addresses, secure access over WiFi, and facilitate basic communication, access, and content consumption.
Business VPNs basically run VPN gateways in multiple data centers (or PoPs) that they own. This offers greater security while eliminating the need to install on-premises appliances. The business services also provide better support for cloud connectivity.
