Data Sovereignty in Indonesia: Requirements and Challenges for Companies

A fintech company in Jakarta was once reprimanded by a regulator because its customers’ transaction data was stored on servers overseas without a clear data processing agreement. The compliance team only became aware of the problem during an annual audit, and fixing it took months, since part of the infrastructure had to be relocated while compliance documentation was rewritten from scratch.

Cases like this aren’t rare. According to a BARC study titled Data Sovereignty 2026: Reality, Relevance, Roadmap, 89 percent of organizations worldwide consider data sovereignty a very or fairly important issue, and 76 percent expect its urgency to keep rising.

These figures show that data sovereignty is no longer just a legal formality. For companies operating in Indonesia, understanding the requirements and challenges of data sovereignty has become an important part of business strategy, not just a matter for the legal team.

What Is Data Sovereignty?

Data sovereignty is the principle that data is subject to the laws of the country where it is collected, stored, or processed. This principle asserts that anyone managing the data of an Indonesian citizen, including foreign companies operating across borders, must still comply with Indonesian regulations as long as that data falls within its jurisdiction.

Many people assume data sovereignty is the same as data residency. In fact, the two are different: data residency only concerns the physical location where data is stored, while data sovereignty covers much more, namely who has the right to access the data, which laws apply, and how audits or law enforcement can be carried out.

As a simple illustration, a hospital in Surabaya might store its patients’ medical records in a local data center (satisfying data residency). But if the cloud service provider managing that server is a foreign company subject to another country’s laws and could be compelled by its home government to grant access to the data, then sovereignty over that data hasn’t actually fully rested in Indonesia’s hands.

This distinction is what makes data sovereignty a broader concept. It covers legal control, technical control, and operational control over data, not just server location.

Why Data Sovereignty Matters for Companies in Indonesia

There are several concrete reasons this issue is becoming more urgent for companies to pay attention to, ranging from global trends to everyday operational risk. Each of these factors is explained below.

Digital Economy Growth and Data Volume

The more transactions, public services, and business activities that move onto digital platforms, the larger the volume of personal data companies have to manage. This growth has made overseeing data location, access, and processing far more complex than it was five years ago.

For example, a marketplace that once served only domestic buyers now has to manage payment data, addresses, and transaction history from millions of users while storing it in compliance with applicable rules. At this scale, a small governance mistake can have a wide-reaching impact.

Rising Risk of Data-Related Incidents

As more organizations operate across jurisdictions, the risk of incidents related to data management rises accordingly. The Kiteworks 2026 Data Sovereignty Report found that 33 percent of organizations worldwide experienced a data sovereignty-related incident in the past 12 months, with the manufacturing sector recording the highest incident rate at 52 percent because of its cross-border supply chains.

Imagine a logistics company that integrates its systems with partners in several countries. If shipping data and customer data get mixed together without a clear jurisdictional separation, a breach in one country could affect operations in another.

Dependence on Global Cloud Infrastructure

Many Indonesian companies rely on multinational cloud providers for their day-to-day operational needs. This trend aligns with the growth of the global market for sovereignty-oriented cloud solutions, which, according to the Data Sovereignty Cloud Global Market Report 2026, is projected to grow from $24.14 billion in 2025 to $29.04 billion in 2026, at an annual growth rate of 20.3 percent.

This market growth signals that more and more companies worldwide are starting to look for cloud solutions that can be configured to remain compliant with local regulations. Companies still using generic cloud services without data sovereignty options risk struggling to meet audit requirements down the line.

Legal Basis for Data Sovereignty in Indonesia

Before discussing technical requirements, it’s important to first understand the legal foundation governing data sovereignty in Indonesia. Several key regulations complement one another and serve as mandatory references for companies.

Law No. 27 of 2022 on Personal Data Protection (UU PDP)

The UU PDP serves as the primary legal umbrella requiring every personal data controller and processor to have a lawful basis for processing, to log all data processing activities, and to fulfill data subject rights such as access, correction, and deletion. This regulation also sets out reporting obligations within a specific timeframe in the event of a data breach.

For example, a digital health app is required to explain in detail to users what data is being collected and for what purpose, and must provide a mechanism for users to withdraw their consent at any time.

Government Regulation No. 71 of 2019 on the Implementation of Electronic Systems and Transactions (PP PSTE)

The PP PSTE classifies data into strategic data, high-level data, and low-level data, with each category subject to different security standards. Strategic data, such as population data, must be managed with the highest level of security and is generally required to be stored within Indonesian territory.

For example, a payment system operator processing population data to verify a customer’s identity must ensure that data is treated as strategic data under PP PSTE, rather than being treated the same as ordinary transaction data.

Other Legal Regulations

Beyond these two primary regulations, there are a number of sector-specific rules that also form part of the legal basis for data sovereignty in Indonesia, depending on the industry a company operates in. These include:

• OJK regulations (POJK) on information technology implementation, which require financial services companies to manage customer data in line with security and reporting standards set by the authority.
• Bank Indonesia provisions for payment systems, which require payment system service providers to maintain the confidentiality and security of transaction data.
• Derivative regulations from the Ministry of Communication and Digital Affairs (Komdigi), which govern the technical obligations of electronic system operators, including data security incident reporting.

As an illustration of how this applies in practice, an insurance company storing its customers’ health data must classify that data as specific personal data under the UU PDP, while also complying with OJK provisions on information technology systems in the financial sector. Both regulations must be satisfied simultaneously, not one in place of the other.

Key Data Sovereignty Requirements Companies Must Meet

Understanding the regulations alone isn’t enough without knowing the concrete steps that need to be taken. Below are five key requirements that are typically the focus of regulatory audits and oversight.

Data Classification and Mapping

Companies must know what types of data they hold, where that data is stored, and who has access to it. Without clear mapping, a company will struggle to determine the appropriate level of protection for each data category.

For example, an e-commerce company needs to separate basic personal data such as name and address from specific personal data such as ID numbers and payment data, since each requires a different security standard.

Data Storage and Processing Location

For certain data categories, especially strategic data, regulations require storage and processing to take place within Indonesian territory. This requirement is intended to ensure the government can still carry out oversight and law enforcement when needed.

For example, population data used to verify a bank customer’s identity cannot simply be stored in an overseas data center without a special mechanism approved by the relevant authority.

Consent and Data Subject Rights

Every instance of personal data processing must have a lawful basis, the most common of which is explicit consent from the data owner. Companies are also required to provide a mechanism for individuals to submit requests to access, correct, or delete their data.

As an illustration, a digital health app must provide a feature allowing users to withdraw consent for the use of their medical history data at any time, not just during account registration.

Technical Security and Regular Audits

Data protection isn’t sufficient at the policy level alone; it must be backed by technical controls such as encryption, access management, and system activity monitoring. Regular audits are also needed to ensure all of these controls are functioning in line with applicable standards.

A simple example: a company storing employee data must ensure that only HR staff and authorized parties can access payroll data, and that every such access is logged in an audit trail.

Cross-Border Data Transfer Mechanisms

When data needs to be sent abroad, for instance for processing by a regional headquarters, a company must ensure the destination country offers an equivalent level of data protection or use a contractual mechanism approved by the regulator. Without such a mechanism, cross-border data transfers risk violating the UU PDP.

For example, a multinational company sending its Indonesian employees’ data to a central HR system in Singapore needs to put in place a data processing agreement containing equivalent-protection clauses before the transfer takes place.

Challenges in Implementing Data Sovereignty in Indonesia

Beyond meeting the requirements above, companies also face a number of practical obstacles on the ground. The following challenges come up most often during implementation.

Dependence on Foreign Technology Vendors

Many of a company’s core systems, from CRM to collaboration platforms, are developed by global vendors whose data centers are located outside Indonesia. Migrating or reconfiguring these systems takes considerable time, cost, and technical coordination.

A retail company, for instance, only realized that the point-of-sale system it used stored transaction data on overseas servers after its legal team conducted a full compliance audit.

Complexity of Hybrid and Multicloud Infrastructure

Modern organizations typically run a combination of on-premises systems, private cloud, and public cloud simultaneously. This combination makes mapping data flows complicated, especially when each system is managed by a different team without proper coordination.

As an illustration, an IT team might not even be aware that one internal application module is still sending backup data to a third-party cloud service located overseas.

A Talent Gap in People Who Understand Both Regulation and Technology

Implementing data sovereignty requires people who understand both regulation and technical architecture, and this combination of skills remains scarce at many companies. Legal teams are often unfamiliar with the details of cloud infrastructure, while IT teams may not fully grasp the nuances of data protection law.

This is evident at companies that have only just appointed a single data protection officer, even though compliance oversight needs to cover dozens of systems and hundreds of business processes.

Investment Costs and System Adaptation

Building local infrastructure, conducting security audits, and adapting legacy systems to meet regulatory requirements requires a substantial budget. For mid-sized companies, this cost is often the main barrier to acting quickly.

For example, migrating part of a company’s data from overseas cloud to a local data center can incur significant costs if not planned in stages from the outset.

Practical Steps to Prepare for Data Sovereignty Compliance

Given the requirements and challenges above, companies shouldn’t wait for a regulatory reprimand before taking action. Below are some initial steps that can be taken right away, from data mapping to strengthening documentation.

1. Build a comprehensive data map. Identify the types of data held, where it’s stored, and who has access to it, for example by creating a customer data inventory covering CRM systems, payment applications, and internal databases all at once.
2. Review agreements with cloud vendors. Make sure contracts with cloud service providers clearly state data storage location clauses and security responsibilities, such as confirming the vendor is willing to offer a server region option in Indonesia.
3. Form a cross-functional legal and technical team. Combine legal, IT, and cybersecurity expertise into one team so that policies created can be implemented technically right away, for example a team made up of a data protection officer and system administrator who coordinate regularly.
4. Document data processing activities (ROPA). Record every data processing flow in detail, from the data source and purpose of use to any third parties involved, so it can be easily traced during an audit.
5. Track user consent history. Keep evidence of when and how users gave their consent, for example through digital logs recording the time and the version of the privacy policy that was agreed to.
6. Conduct regular security audits. Schedule routine checks of access controls and data encryption, such as quarterly audits involving both internal security teams and independent third parties.

Companies that carry out these steps consistently will be far more prepared whenever they need to face a regulatory examination.

Conclusion

Data sovereignty in Indonesia isn’t simply about storing data on local servers, it involves legal compliance, technical security, and comprehensive governance over the data a company manages. Regulations such as the UU PDP and PP PSTE require companies to understand data classification, storage location, data owner rights, and cross-border transfer mechanisms in detail.

At the same time, challenges such as dependence on foreign vendors, infrastructure complexity, and limited talent mean this compliance process can’t be completed overnight. Companies that succeed are usually the ones that start building data governance gradually and with proper documentation, rather than waiting for an incident to happen first.
