DUO Accesws Gateway | Supported on Server 2019?

HI folks,

Can anyone give me a definitive answer. Is DUO Access Gateway supported on Windows Server 2019.

I know the proxy is however, it’s not clearly stated in the DUO kb’s from what I can see.

Thanks in advance,


We currently have our DAG servers running on Windows Server 2016 without issues. Per Duo Access Gateway for Windows | Duo Security, Server 2019 isn’t officially listed, but architecturally there doesn’t seem to be that big a difference between '16 and '19.

If you haven’t done so, I’d hit up support or your customer service rep and see if/when they will certify '19 for support. No telling how log it will be before the Duo Docs pages will be updated.

Hi ButlerKevinD,

Thanks very much for your response.

I have indeed already opened a support ticket with DUO support however, I’ve heard nothing from them regarding this as yet.

Fingers crossed I might hear something from them by the end of the week :frowning_face:

The Duo Access Gateway is currently supported on 2012 R2 and 2016. You can subscribe to our release notes to be notified of Windows version support changes in a future release.

ETA here is a list of the Duo applications explicitly supported on Server 2019: Multiple Duo applications now support Windows Server 2019.
