Data sovereignty in Latin America: the new regulatory and technological battleground of 2026

Data sovereignty—the ability of a country or company to decide where its information is stored, who processes it, and under what law it is governed—was consolidated as a regulatory priority in Latin America in 2026. Brazil formalized its data protection authority as an independent agency, Mexico updated its privacy law, Colombia strengthened technological oversight of the financial sector, and the sovereign cloud market is growing at a rate of nearly 30% annually globally.

What does “data sovereignty” mean and why does it matter now?

Data sovereignty is not limited to the physical location of a server. Industry specialists describe it as a matter of governance: who has the final say on access, portability, and processing of information, even when it is stored on third-party infrastructure. The discussion gained urgency in the region following the US Cloud Act, which allows US authorities to request access to data managed by US companies regardless of where the servers are located, reopening the debate on jurisdiction and control in Latin America.

For more than a decade, migrating to large public cloud providers was a rational decision for businesses and banks: it reduced investment in hardware and operational complexity. But that move also involved delegating critical decisions about jurisdiction and data handling, something that is especially sensitive today for regulated sectors such as finance, healthcare, and digital identity.

Brazil sets the regulatory pace for the region

According to multiple analysts and the IAPP (International Association of Privacy Professionals) itself, Brazil is the country leading the digital sovereignty agenda in Latin America:

• On April 8, 2026, the National Data Protection Authority (ANPD) was formally consolidated as an autonomous regulatory agency, with its own budget and structure, after years of operating with less institutional independence.

• The ANPD has already defined its 2026–2027 priority map, focused on the protection of children’s data, artificial intelligence and automated decision-making, and public sector governance.

• The country is making progress in building a sovereign public cloud operated by Serpro, its state-owned technology company, and has signed an agreement with the China Academy of Information and Communications Technology to define digital governance standards.

• Brazil’s State Artificial Intelligence Plan, launched in 2024, envisions an investment of 23 billion reais (about USD 4 billion) until 2028 to boost local developments and ensure data processing within the country.

• In April 2026, the Brazilian Ministry of Communications confirmed the approval of more than 4 billion reais through a universalization fund to expand fiber optics and build data centers.

• According to Reuters, Tecto Data Centers announced a $2 billion investment through 2028 in five new facilities in Brazil, reinforcing the country as a priority destination for large-scale digital infrastructure in the region.

Mexico, Argentina and Chile: uneven progress

The regulatory landscape is not homogeneous:

• In 2016, Mexico enacted a reform to its federal law on private sector data protection, though it largely maintains the regulatory framework of 2010. The new personal data authority has yet to issue secondary regulations or public sanctions, but there are indications of preliminary investigations into the handling of sensitive data and security incidents. Meanwhile, the Mexican government is moving forward with a biometric digital identity system.

• Argentina is singled out as the paradigmatic case of deregulation in the region: data travels, is processed and stored with little local supervision, little specialized professional training and limited public debate on the risks of technological concentration.

• Chile renewed its data protection regulations two years ago, aligning them with the European standard, although the sector expects further regulatory moves towards the end of 2026.

A recurring diagnosis among regional analysts is that, beyond specific cases like Brazil, there is a relevant institutional gap in data sovereignty and privacy in Latin America: a shortage of specialized technical profiles, limited funding, a lack of its own regulations, and high technological dependence on foreign providers.

Colombia: the financial sector under scrutiny

Colombia offers one of the most concrete examples of how data sovereignty translates into sectoral regulation:

• Circulars CE 006 of 2025 and CE 004 of 2026 from the Financial Superintendency of Colombia tightened the requirements for technological risk management, information security and third-party supervision for supervised entities.

• Between January and July 2025, attacks against Colombian banks increased by 69% compared to the same period in 2024, according to figures from the Financial Superintendency and Asobancaria, with an average of 94 attack attempts per second recorded in the system.

This tightening of regulations forces banks, insurers, and fintechs to raise their requirements for traceability, supervision, and responsiveness in critical environments, a terrain where cybersecurity, digital identity, and data sovereignty converge.

Market figures: cybersecurity, sovereign cloud, and digital identity

Market size estimates vary by consultancy, but all point in the same direction: sustained double-digit growth.

Discrepancies between analysis firms (e.g., $12 billion versus $23 billion for the same market and year) reflect methodological differences about which segments are included—hardware, software, managed services—and are a reminder that market figures should be read as orders of magnitude, not as exact data.

One common thread running through these reports: Identity and access management (IAM) consistently emerges as one of the drivers of this growth, fueled by stricter privacy regulations and the accelerated adoption of the cloud in the region.

Why this matters to regulated sectors

For banks, insurance companies, airlines, and government entities, data sovereignty is no longer an abstract debate: it translates into concrete decisions about where to store biometric information, how to validate the digital identity of customers and citizens, and what contractual guarantees to demand from cloud and identity providers. The consolidation of independent regulatory agencies (such as the ANPD in Brazil), the tightening of sector-specific regulations (as in Colombia), and the increase in attacks on critical infrastructure are pushing these sectors to prioritize providers capable of operating under local compliance frameworks and with real data localization options.
