NetScaler now supports (hybrid) Post-Quantum Cryptography (PQC) which will be soon NIST's new default.

Windows Cloud - Windows App for Web (HTML5) Test results from the new Windows App for Web with both AVD and Windows 365 Cloud PC with vGPU, compared to the old HTML5 Portal from AVD.

Finally, I did some tests with maxing out Windows App for Web (HTML5). In the past, HTML5-based solutions primary were an alternate or fallback possibility to connect to it's EUC-solution, when the main native Client wasn't available.

Citrix DaaS - Filtering Published Apps with Entra ID Groups Using Entra ID groups as a filtering mechanism for published apps on Citrix DaaS can result in failed app launches. Learn why.

In the past, filtering published Apps visibility on Citrix #DaaS with Entra ID groups was only possible when linked to application groups.

Now, you can add the filter on the published app, directly. But watch out regarding a minimum VDA version.

NetScaler - HDX and Gateway Insight stopped working Migrate from AppFlow Policies to Analytics Profiles to get HDX and Gateway Insight to work again with NetScaler Console.

It looks like there are a bunch of broken (empty) NetScaler Console HDX / Gateway / Web Insight or Security Violations since the latest NS and NSC 14.1 47.46 Firmware.

Migrating to Analytics Profiles solved my issues. www.julianjakob.com/netscaler-hd...

NetScaler - Enhanced Authentication Feedback Template Using a simple Template for Enhanced Authentication Feedback on NetScaler for better Enduser-Understanding without the lack of Security.

“Try again after some time or contact your help desk” isn't a helpful error-message for Endusers trying to logon to your #NetScaler Gateway or AAA Pages. On the other side, giving to much detailed informations to public is harming your safety. www.julianjakob.com/netscaler-en...

2/2 The root cause is, after HA-Failover, the WAF profile ns-aaa-default-appfw-profile is gone. The User gets a Connection-Reset when trying to browse to any NSGW-URL (with Auth-Profiles in use)

Workaround is to disable WAF or set to "VPN" only.

The issue will be fixed in 14.1 43.x and later.

1/2 Watch out when using NetScaler integrated WAF for AAA and NSGW:

There's an issue (NSCXLCM-7372 - confirmed for 14.1 Build 38.53, but I am able to reproduce it also with 34.42 and 29.72) where WAF configured for "AUTH and VPN" is blocking all NSGW Traffic after a HA-Failover took place.
