Describe software VPN systems.

What will be an ideal response?

Software VPNs are generally less expensive than hardware systems, and they tend to scale better on fast-growing networks. These products support traveling employees who need private access to an  organizational LAN or intranet from any dial-up location, IT staff who need the ability to secure internal networks and partition parts of the network, and organizational  partners who require secure connections to a company's data network for business collaboration.
