Cloud Adoption for work from home user

Under the outbreak of COVID19, we are encouraging work from home model. We are migrating the intranet web servers, and application servers to the AWS EC2. For best protection, I would like to know if there is any solution for WFH user to have remote access (such as VPN) to AWS? If possible, is there any AWS native remote access VPN available rather then using third party Cloud base Firewall?
