AWS Client VPN is a managed service that allows organizations to access AWS resources from remote locations using OpenVPN-based clients. The pricing model of AWS Client VPN can be confusing, and it charges based on a time-connected basis for each type of component required to use the service: Client VPN endpoint associations and user connections to an endpoint. Each Client VPN Endpoint Association costs between $0.10 to $0.15 per hour, while each client connected to a VPN endpoint costs $0.05 per hour. Additionally, there are bandwidth fees for egress traffic from your VPC and NAT gateway data processing charges if you use one in your VPC that handles full tunnel traffic. However, AWS Client VPN is not the only option for enabling secure remote access to AWS VPC environments. Alternatives include AWS Marketplace products, such as Cisco Adaptive Security Virtual Appliance (ASAv), and manually installed open source solutions like OpenVPN, which require more effort and expertise in setup and maintenance. Another alternative is Twingate, a Zero Trust Network Access product that doesn't use VPN technology, with a straightforward pricing model based on a per user flat fee model. Twingate aims to provide the security benefits of a non-VPN Zero Trust solution while making deployment and management simple and cost-effective.
