The legacy traditional hardware VPN was first introduced over 30 years ago. It initially enabled secure and remote access to the Internet through a point-to-point connection by creating an encrypted ‘tunnel’ through which IP traffic flows. Despite the advancements of VPNs over the years, outdated remote access creates more security risks for enterprises. By organizations adopting VPNs for corporate network access it presented the issue of increasing more vulnerable attacks on the networks due to employee access within the organization network in order to access company resources. Organizations that are adopting consumer VPNs are providing weaker points of encryption with respect to identity access and credential management. Users who are not restricted to specific network resources are making VPNs one of the easiest targets for hackers to attack.
Critical VPN constraints include lack of network segmentation, network visibility, on-premises user security as well as lack of secure network security. VPNs are also not suited for the increasing use of cloud resources because they require computer hardware, constant management and cannot easily adjust to network or server changes. This makes it more problematic to scale for new users and network locations.
In comparison, the Corporate VPN model addresses traditional VPN limitations while providing a more flexible cloud-based platform, increased security, privacy and user-access control granularity and analytics.
