NetScaler Times newsletter for Week 29 - 2025
A Fond Farewell to Andrew, and Hello from Your One Of Your New Editors
Hello Everyone
It’s Steven with the latest edition of the NetScaler Times, an update to keep you up-to-date on all things NetScaler-related! With Andrew having moved on to new adventures, I’m picking up the torch to continue pulling together events, firmware releases, support articles, and anything else I think is relevant into a single email, as email is the future!
1. Updated NetScaler Credentials: Your Path from Associate to Professional
Missed the latest NetScaler certification updates? Citrix just streamlined the path to becoming a certified NetScaler Associate or Professional with new CCA-AppDS and CCP-AppDS credentials for version 14.x. From Gateway administration to advanced ADC architecture, these globally recognized certifications validate your skills and open doors. Training resources and exam details included for pros ready to prove their expertise!
2. 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 provides additional information on the various 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 behaviour will be the same regardless of whether it is used as hardware, a virtual machine, bare metal, or a container. Select 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:
Notes about Builds:
Which release should I use?
The release families are designed so that 14.1 has more elements changing with each update, hence the feature phase designation. Due to its maintenance phase, 13.1 will have fewer changes now.
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 re-architecting 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
The lists below have the recent appliance status changes. These have been revised to be a bit more exhaustive.
EoS Appliances
These appliances are End of Sale (unavailable to buy new now), they will live and run for 5 more years from 2024/2023. Just add 5 years to the EoS date to get the EOL.
EOL Appliances
A table shows the EOL appliance events for the last 18 months. April had a few appliances reach their end of life and must be replaced (to get support). The MPX/SDX 16000 is the replacement in most cases.
I pulled these summary tables from the official site here. Just open and expand the NetScaler section.
