NetScaler Times newsletter for Week 20 - 2025
NetScaler Kubernetes Gateway Controller ships!
Hello Everyone
It’s Andrew with the latest edition of the NetScaler Times, an update to keep you up-to-date on all things NetScaler-related! Why read this? To make you soar with the eagles 🦅 !
The idea is to pull together events, firmware releases, support articles, and anything else I think is relevant into a single email.
High-level agenda for this week:
The email is the NetScaler Times newsletter for Week 20 - 2025, providing updates on NetScaler-related events, firmware releases, and support articles.
The newsletter includes details on the latest NetScaler firmware builds, security updates for CVE-2024-5491 and CVE-2024-5492, and NetScaler WAF Signatures Update v152, updated on 12th May.
Information on the newly released NetScaler Kubernetes Gateway Controller, documentation links, and the official Helm Chart are provided.
Updates on End of Sale and End of Life appliances, along with replacements, are listed.
The newsletter encourages feedback via Andrew.Scott@cloud.com.
1. The latest firmware builds.
Below are the details for the various builds, which can help you plan for new releases in your environment. This support document has more information on the different release cycles.
NetScaler has multiple form factors to support different environments. It is built on a single operating system with a software-based architecture, so its behavior will be the same regardless of whether it is used as hardware, a virtual machine, bare metal, or a container. Pick one that works for your environment and needs.
Latest Build Versions:
Here is a timeline for the 14.1 and 13.1 builds to show where they are within their respective release lifecycle.
Here are all the firmware builds in a table:
NetScaler Console 14.1-50.33 Build
This has a bunch of fixes, and the release notes are here

Which release should I use?
The release families are designed such that 14.1 has more elements changing with each update, hence the feature phase designation. There will be fewer changes in 13.1.
An example of the move to 14.1 might be that you want to take advantage of removing the dependency of ALB in Azure with your NetScaler HA deployment. Read more here. This could save some $$$ (insert local currency).
Also, a recent customer request included plans to build a new Azure infrastructure. This was not expected to be a short-term deployment. Looking at the build cycles above, it would make sense to start looking at 14.1 for this. This would avoid having to re-architect the solution next year when 13.1 moves to CVE-only support.
What about NetScaler SDX?
There are multiple NetScaler designations. VPX, MPX, SDX, BLX, and CPX all use the same firmware. The table above applies to all NetScaler types. It might not be the same download file, as appliances like the SDX do have other elements to update.
End Of Sale Appliances & End of Life Appliances
There are some short lists below with the more recent appliance changes.
EoS Appliances
These appliances are End of Sale (unavailable to buy new now), they will live and run for 5 more years from 2024.
EOL Appliances
A table shows the significant EOL appliance events for the next 12 months. Last month (April), a few appliances reached their end of life and must be replaced. The MPX/SDX 16000 is the replacement.
2. Latest NetScaler Security updates
NetScaler ADC and NetScaler Gateway Security Bulletin for CVE-2024-5491 and CVE-2024-5492.

4. NetScaler Kubernetes Gateway Controller.
Just released in the last few days, thanks, Mayur Mohan Patil!
Announcement: NetScaler Kubernetes Gateway Controller (Kubernetes Gateway API implementation) has been released!!!
As you are aware, the NetScaler Ingress Controller (NSIC) configures the ingress resources in NetScaler for Kubernetes/OpenShift workloads. Kubernetes has introduced the Gateway API (ingress V2), and we are committed to aligning with this advancement.
The NetScaler Kubernetes Gateway Controller seamlessly integrates NetScaler’s Application Delivery Controller (ADC) capabilities with Kubernetes, leveraging the Kubernetes Gateway API to deliver advanced traffic management, enhanced flexibility, and secure application delivery for Kubernetes environments.
Please visit NetScaler Kubernetes Gateway Controller for a comprehensive overview of key features, benefits, and how this solution enables secure and efficient application delivery in Kubernetes environments.
