Market Need
Deploying one or a few VPN seems an easy job. When there is a need to deploy tens or hundreds of VPNs, it becomes an issue.
For example, for a business with large number of franchise branches, to provide VPNs to all of them, is a challenge.
1. These branches could be located in different places or cities or countries. Going on-site is a costy solution.
2. Each franchise may have their employee turnover rate. Enable and disable these employees is a costy long term management burden.
3. These franchise could use different ISP which may have present difficulties for deploying VPNs.
4. These franchises may belong to different owners. Changing their network devices may result liability initially or long run. No one would like to be liable for the whole network maintenance just because introducing a VPN.
