What is Data Residency?

TL;DR: Data residency refers to the physical or geographic location where data is stored and processed. Many regulations (GDPR, data sovereignty laws) and enterprise contracts require that data remains within specific jurisdictions such as the EU or US.

Data Residency for SaaS Companies

Data residency requirements are driven by regulations, customer contracts, and national data sovereignty laws. For B2B SaaS companies, offering data residency options is increasingly a deal requirement, especially for EU-based customers.

Why Data Residency Matters

GDPR — While GDPR allows data transfers with adequate safeguards, many EU organizations prefer (or require) EU-based data storage
Customer contracts — Enterprise buyers often require contractual guarantees about data location
Government regulations — Some sectors (healthcare, finance, government) mandate in-country data storage
Schrems II — The invalidation of Privacy Shield increased scrutiny on EU-US data transfers
