Why digital sovereignty matters with HUMAN Security (PerimeterX)
HUMAN Security (PerimeterX) 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.
HUMAN Security (PerimeterX) hosts data in US, EU, APAC. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.
HUMAN Security (PerimeterX) is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.
What this means for your organisation depends on your whole stack and context. The free assessment weighs HUMAN Security (PerimeterX) together with your other vendors and gives a total score, a heatmap and the main risk drivers.
