VPN is a disruptive technology which has replaced the traditional insecure network communication system like WAN. VPNs allows us to utilize the internet infrastructure for secure private communication between institutions, workplace or even remote sites.
Before, to access a school’s LAN we were supposed to be present on site but now it’s entirely possibly to access all the resources on the school’s LAN just staying home. By making few changes to the LAN infrastructure of school, VPN can be easily integrated and this allows many users to access a school’s network from home. VPN is still developing and it’s a great advantage for businesses who are expecting to expand their services over long distance globally.
