Why are VPNs so secure?

While VPNs provide traffic encryption and user authentication, they still present a security risk because they grant access to the entire network without the option of controlling granular user access to specific resources. There is no scrutiny of the security posture of the connecting device, which could allow malware to enter the network. To maintain proper security, traffic must be routed through a security stack at the VPN’s terminus on the network. In addition to inefficient routing and increased network latency, this can result in having to purchase, deploy, monitor, and maintain security stacks at multiple sites to decentralize the security load. Simply put, VPNs are a challenge – an expensive one at that – when it comes to remote access security.
