Adversarial Robustness Toolbox: sovereignty score and 8 European alternatives

The Adversarial Robustness Toolbox (ART) is a Python library for machine learning security. Developers and researchers use it to test and defend models against four kinds of threat: evasion, poisoning, extraction and inference. ART supports frameworks such as PyTorch, TensorFlow and scikit-learn and works with data types including images, tables and audio. It is a library you install yourself; there is no separate cloud service.

ART was originally developed by IBM and moved in 2020 to the LF AI & Data Foundation of the Linux Foundation. The code is available under the MIT licence. Because the library runs locally, models and test data stay on your own infrastructure and no vendor processes data. For European organisations this means little dependency on a cloud service, but a dependency on a project hosted by the Linux Foundation and originally contributed by IBM. The MIT licence allows you to maintain your own fork.

Why digital sovereignty matters with Adversarial Robustness Toolbox

Adversarial Robustness Toolbox 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.

Adversarial Robustness Toolbox hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Adversarial Robustness Toolbox is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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