NetScaler 13.1 vs 14.1
Which version is right for your business?
At Blubyte, we know that choosing the right NetScaler version is about more than just features. It's about aligning technology to your business goals, risk profile, and appetite for innovation. As Citrix NetScaler specialists, we help organizations make informed, future-proof choices for their application delivery and security needs.
Understanding NetScaler release cycles: Maintenance vs. Feature releases
Before diving into the version comparison, it’s crucial to understand how NetScaler’s firmware release cycle works:
Feature releases: These are the cutting-edge versions where Citrix introduces new capabilities, enhancements, and innovations. Feature releases are ideal for organizations that want to leverage the latest technology and are comfortable adopting new features as they become available. Each feature release is supported for three years, with regular updates during this period.
Maintenance releases: Once a feature release matures, it transitions into a maintenance phase. Here, the focus shifts to stability, bug fixes, and security updates, no new features are added. Maintenance releases are perfect for businesses that value predictability and reliability, especially for mission-critical environments. The maintenance phase also lasts for three years, followed by a year of extended support for urgent security patches.
NetScaler 14.1: Freemium option and innovation
Why consider NetScaler 14.1?
Freemium (VPX express) now available: With version 14.1, Citrix has made the popular VPX Express edition available as a true freemium option. This means you can deploy NetScaler with all premium features unlocked, up to 20 Mbps throughput, without the need for a license file or financial commitment. It’s perfect for testing, labs, or small production environments wanting advanced features at zero cost.
Continuous feature enhancements: As the current feature release, 14.1 is where Citrix is focusing its innovation while delivering the latest in security protocols, automation, analytics, and integration capabilities.
Ideal for early adopters: If your business is looking to stay ahead of the curve and take advantage of the newest NetScaler capabilities, 14.1 is the clear choice.
