    If you looking for a reliable, light weight and secure VPN server, than OpenVPN Access Server is the one. Easy to install and manage, OpenVPN will provide secure remote connections, with a very good integration with almost all LDAP directories, for user management. With my experience, I don't see any scenario that OpenVPN won't be able to handle.

    integrates seamlessly with Windows servers via WMI and PowerShell, providing deep insights into resource usage, performance metrics, and system health. It's excellent at tracking CPU, memory, disk space, and event logs, enabling rapid troubleshooting and proactive maintenance. PRTG Network Monitor also effectively monitors Fortigate devices, providing detailed data on firewall health, traffic patterns, bandwidth utilization, VPN status, and security alerts. This visibility helps detect and resolve network security issues promptly.

    Cons
    OpenVPN
    • some times error logs are not clear
    • Configuring 3rd party apps can sometimes be problematic
    • Limited functionality for iPhone users, but I believe that is due to an apple issue.

    • Licensing on a per entity basis can be cumbersome for devices which have a ton of monitoring points like network switches\routers. Each sensor may count against a license, which could be a lot of you were monitoring every TX\RX of an SFP for example
    • A better method to easily template\copy monitors across devices
    • The navigation in the web GUI could be a little more straightforward in terms of the hierarchy

    I would renew it because the platform has brought us many technical and economic benefits that make the cost-benefit ratio very good. Additionally, to do so does not require large investments in training, licensing or infrastructure, and at the administration level, extensive knowledge is not required to be able to bear it.

    Usability
    OpenVPN
    Whatever console or firewall you are running OpenVPN Access Server, it's configuration is very easy to do. You can create multiple tunnels, with different pourposes and authetication methods. It also has a quick and easy view of the connections opened, with possible actions, such as a very efficient kill switch and reconnect options.

    The tool is very intuitive to use and it is Windows-based (everybody knows how to use Windows) so it's easy to get into. Every time is setup in a hierarchy so if you have a good initial hierarchy design, it will really reduce administrative effort down the road.

    PRTG does everything we need it to do and more. Ease of use, ease of management and maintenance and clarity of monitoring of hundreds of different types of device and service gives this a large advantage over other products on the market that I have tried. I would definitely recommend it to anyone who needs a network monitoring product in their environment and even to people who don't know they need a solution yet!

    It's very important that de project's teams have different member of the TI. We have learned too late the importa of Security Analyst at the design architecture moment. We have to rebuild part of the implementation for made this big mistake.

    OpenVPN had a better UI and usability for our team. It was more straightforward, had better SAML integration, and allowed our team to be on the VPN and on our network in seconds. We had some issues getting Nord to work for our use cases, and have run into pretty much zero issues with OpenVPN.

    PRTG offers more versatility in monitoring when compared to the other solutions we tested. The other solutions were also limited as far as customization options, which made them less adaptable to our networks. When compared to Auvik, for instance, we prefer PRTG as it offers immediate notifications through the desktop client - not limited to email notifications as with Auvik. We also appreciate the fact that PRTG can be self/on-prem hosted vs Auvik's cloud model. This makes for an easier deployment and less firewall adjustments to allow traffic to cloud-hosted solutions.

    Return on Investment
    OpenVPN
    • Only 2 free users, it would be nice if they would expand to 5.
    • Easy way to establish a VPN backbone between two locations
    • Great for work at home or BCP events.

    • The ability to analyze multiple pieces of information in one place, especially with historical data, has saved our IT department time and headaches. It would be so much more difficult to trace an issue without PRTG, just relying on event logs and an open task manager window.
    • The cost is not cheap, so it's an expense that hits the bottom line like everything else. Figure in hardware costs as well, ideally a server outside of your main environment.
    • I keep saying this, but the historical data piece is worth so much. There's really no good way to collect all of that information in one place without something like PRTG. And that definitely saves time and money in the long run.
