Sovereignty profile of NetScaler

How this vendor scores on the five dimensions of the Digital Sovereignty Heatmap: 0 is sovereign, 100 is high exposure. These are the same scores the assessment uses.

Jurisdictional exposure (JES)	Headquartered in the US: CLOUD Act and FISA 702	90
Data residency (DRS)	EU-only hosting	0
Cryptographic key sovereignty (CKS)	Closed source, but self-hostable: encryption keys and runtime under your own control	20
Platform lock-in (PLS)	Closed source: switching requires data migration	60
Source & runtime sovereignty (SRS)	Closed source, but self-hostable on your own infrastructure	45
Average		43

Why digital sovereignty matters with NetScaler

NetScaler is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

NetScaler runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

NetScaler is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs NetScaler together with your other vendors and gives a total score, a heatmap and the main risk drivers.
