User management has simplified internal VPN access and now provides clear visibility and control
I do not use any role defining features because it is a really small organization, so it wasn't required, but it is there if needed. I have seen OpenVPN Access Server integrations such as LDAP, RADIUS, PAM, and SAML, but again, due to the size of the company, it wasn't necessary and we didn't have it inside the company. However, it was nice that it is already embedded inside. We haven't used much in terms of integrations with OpenVPN Access Server, so it's hard to say. We only used basic features there. My advice for others looking to implement OpenVPN Access Server is that it is at least worth trying if you need a fast and easy implementation solution without technical overhead and you just need VPN access, which is supported by all operating systems and mobile operating system vendors. It is definitely worth a try. OpenVPN Access Server was purchased directly from the website, not on the AWS marketplace or through a partner purchase. I would rate this product an overall eight out of ten.
