Most companies are turning to virtual private networks (VPNs) to reduce costs and increase security and performance. By using a public network, VPNs can connect off-site users, such as teleworkers and remote workers, vendors, and customers, to a larger centralized network. A VPN is considered as important as the internet connection itself, therefore choosing the right VPN solution is essential.
There are several different VPN solutions in the market today, therefore extra caution must be taken to ensure that the best possible decision is made when choosing a business VPN solution.
The two main product categories are dedicated VPN hardware appliances, and software VPNs (also called server-based VPNs). In the case of software VPNs, the VPN endpoint is actually software running on the device itself, whereas a hardware VPN is a virtual private network based on a single, stand-alone device.
The following four key points highlight how software VPNs are superior to hardware VPNs:
VPN software is generally considered to be a relatively low-cost way to deploy a VPN; dedicated hardware VPN appliances are more expensive than a software VPN because, generally, the VPN software is installed on an existing device. This means there is virtually no other investment required apart from software upgrades.
- Easy Network Management
A further advantage to the software VPN approach is that the network does not change. No additional devices need to be installed, and management of the network remains the same. In contrast, a VPN appliance involves adding a new piece of equipment to the network, therefore increasing the complexity of the networking environment.
- Less Training
Another benefit is that generally, less training is required in the case of software VPNs. Conversely, in hardware VPNs, the IT staff would require more intensive training since the configuration and management tools will probably be different than the ones used on the corporate routers.
- Performance and Scalability
The performance factor is equally as important. The ability to expand the VPN to support more sites or users should not be underestimated when choosing a VPN. Pure software VPN solutions benefit from high scalability. This is not the case for a hardware VPN. If a company were to start with a VPN appliance designed to support 50 simultaneous VPN sessions, and later experience considerable increases in personnel, the VPN would need to accommodate more users. This would require scaling up the VPN will require the purchase of more appliances. Selecting a VPN that is not scalable can easily double the cost if or when the VPN capacity is outgrown.
When choosing a VPN, special attention should be paid to the merits of the various deployment models (SSL VPN vs. IPsec VPN). Modern, pure software SSL VPNs do not require the installation of specialized client software on the end user’s computer. This translates to high scalability and the ability to support many different platforms (such as Windows®, Mac, Linux/Unix), from virtually any device. SSL VPNs enable secure server-based computing environment with strong SSL encryption and strong authentication.
