Data Residency: Definition, Laws, Requirements, and Everything Else You Need to Know

Data permeates nearly every aspect of our lives. We entrust organizations with the vast amounts of personal information they collect and use, from names and addresses to financial details and online activity. Because of this, concerns about how organizations manage personal data are at an all-time high.

Data protection and privacy regulations around the world have thus been enacted in order to give individuals more control over their personal data. The General Data Protection Regulation (GDPR) in Europe, the California Consumer Privacy Act (CCPA) in the United States, and the Personal Information Protection Law (PIPL) in China, among others, are all designed to protect personal data by mandating how organizations handle that information.

One common element of these regulations concerns data residency—where data is physically stored. This blog post will explore the details of data residency, explaining what it is, how it impacts businesses, and the legal implications organizations and individuals need to consider. We will also examine various data residency laws, discuss compliance requirements, and offer solutions for managing data residency effectively to ensure your business is compliant and protects your customers' data privacy.

What is data residency?

Data residency refers to the physical location where data is stored. This includes your organization’s on-premises servers at each of your locations and your cloud provider’s servers, wherever they may be. Your headquarters and your cloud provider’s headquarters might be in one location, but the servers could be somewhere else entirely. Multinational businesses or businesses that use cloud services in different countries must comply with the local or regional data residency regulations of each country in which they operate.

To add complexity, the locations of the individuals whose data you store influence which country’s regulations apply. Knowing exactly where your organization’s data is stored helps ensure compliance with all applicable data residency laws.

Organizations choose where their data is stored based on a number of factors. Company policies often guide data storage practices to align with strategic goals while complying with regulations. Data residency requirements are often based on the geographical location of the data subjects (users). For example, data collected from citizens of the European Union (EU) citizens must comply with GDPR, regardless of where the company is based. Different countries have various laws and regulations that require specific data storage locations to protect data privacy and security.

Understanding how data residency influences organizational operations helps them avoid legal and regulatory issues. It also provides customers with assurance that their personal information is stored and managed according to local laws, enhancing their trust in businesses.

What’s the difference between data localization and data residency?

While data residency and data localization are related, they are distinct concepts. Data residency refers to the geographical location where data is stored to comply with local laws. Data localization goes a step further, mandating that data must be stored and processed within a specific location, often the user's country. This stricter approach is driven by national security concerns or a desire for greater control over citizen data.

Data residency regulations are becoming common, while data localization laws are less widespread but can significantly impact global businesses. By understanding both concepts, businesses can ensure compliance and navigate the evolving data landscape.

Data residency laws and regulations

Data residency laws and regulations vary widely across different countries and regions, but they all regulate how personal data is stored and managed:

• The General Data Protection Regulation (GDPR) is arguably the most well-known data protection regulation. It requires that the personal data of EU citizens is stored and processed in a manner that ensures their privacy and security. Any organization that handles the data of EU citizens must comply with GDPR, regardless of where the organization is located. This often means storing data within the EU or in approved locations outside its borders.
• California Consumer Privacy Act (CCPA): Similar to GDPR, the CCPA dictates that businesses handling the personal data of residents of California, U.S., must comply with specific data protection standards.
• Personal Information Protection Law (PIPL): China’s PIPL requires that personal data collected in China must be stored and processed within the country unless specific conditions for exporting data are met.
• Australia Privacy Act: Includes data residency requirements that ensure certain types of data are stored within Australia.

The consequences of non-compliance

Non-compliance with data residency laws can result in significant consequences, including penalties, fines, and legal actions. However, beyond the financial costs and operational disruptions, organizations are likely to suffer reputational damage and loss of customer trust, which can be difficult to recover from.

Data residency requirements

Navigating the applicable rules of data residency regulations is different for each organization, so attention must be paid to ensure compliance. While this is not meant to be a step-by-step guide, this list will give you the information you need to build a data management strategy that includes the relevant data protection requirements.

Assess your data landscape

Conducting a thorough data residency assessment is the first step toward compliance. Identify the types of personal data your organization collects, where it originates from, and where it currently resides. This helps you understand which data residency regulations could apply to your business.

Identify relevant requirements

Based on your data landscape and the locations of your users, identify the specific data residency regulations that apply. Consider these factors:

• Geographical location: Identify the locations where data is collected, stored, and processed. This includes both the company’s operations and the locations of its users.
• Applicable regulations: Understand the specific data residency laws that apply to each location. This may involve consulting legal experts or compliance professionals can help you stay updated on the latest requirements.
• Type of data: Determine the categories of data being handled, such as personal data, financial information, or health records, as different types of data may have different residency requirements.
• Data subject rights: Regulations like GDPR grant individuals the right to access, rectify, or erase their personal data. Implement processes to handle these requests efficiently.
• Consent management: Depending on the regulation and location of the users, consent for data collection and storage may be required. Building a robust consent management system is crucial.
• Data transfer restrictions: Some regulations restrict the transfer of personal data outside specific regions. Evaluate your data storage strategy to ensure compliance with these restrictions.

Understand data residency clauses in vendor contracts

• Data storage locations: Ensure vendors store data in locations that comply with applicable data residency regulations.
• Compliance measures: Verify that vendors have robust data protection measures to meet legal requirements.
• Audit rights: Include provisions for regular audits and monitoring to ensure ongoing compliance with data residency requirements.

Ensure compliance now and for the future

Once you’ve established your strategy for data residency compliance, you’ll need to implement and maintain it:

• Use localized data centers: Store data in data centers located within the required geographical boundaries.
• Leverage regional cloud services: Choose cloud service providers that offer regional storage options in compliant locations.
• Implement strong data management practices: Develop and enforce data handling, storage, and transfer policies that align with data residency laws.
• Regularly review compliance: Conduct regular audits and reviews to ensure compliance efforts keep up with evolving regulations.

The challenges of data residency

As you’ve read through this article, you realize by now that there are several challenges for organizations that need to comply with data residency regulations. Here are just a few:

• Increased potential overhead: Adhering to various data residency regulations can be complex and expensive. Businesses might need to invest in legal expertise, specialized data management tools, and compliant data storage solutions.
• Increased complexity for global businesses: Complying with various data residency regulations across different countries can be highly complex for multinational businesses. Depending on the type of data, organizations are likely to need storage in multiple locations in several countries, requiring significant effort and resources and introducing logistical challenges.
• Difficult transfers across borders: Some data residency regulations restrict the transfer of data outside specific regions, complicating tasks like obtaining real-time analytics or performing cloud-based data processing for geographically dispersed businesses. These restrictions can hinder the seamless flow of information, impacting business operations and decision-making.
• Potential limitations in cloud storage options: Not all cloud service providers offer regional data storage options, which can limit an organization’s ability to comply with data residency requirements. This limitation might force companies to switch providers or invest in hybrid solutions, adding to the complexity and cost.
• Balancing security and compliance: While complying with data residency regulations is important, businesses must also ensure that their data is secure. Balancing the need for regulatory compliance with robust security measures can be difficult, especially when data is stored in multiple locations in different countries.
• Evolving regulations: Data residency laws are continually evolving as new regulations are introduced and existing ones are updated. These changes require ongoing monitoring and adaptation, which can strain limited resources.
