Cloud storage has become the default for most U.S. businesses. It is convenient, scalable, and cost-effective. But convenience does not equal compliance. Storing data in the cloud does not remove your legal obligations around privacy and security.
In many cases, it adds new ones, especially when that data crosses state lines, involves regulated industries, or sits on servers managed by a third party.
According to a 2024 Thales Cloud Security Report, 39% of businesses experienced a cloud data breach in the past year. That number reflects a sector still figuring out where operational ease ends and legal exposure begins.
There Is No Single Federal Privacy Law Governing Cloud Storage.
This is where U.S. companies often get confused. Unlike the EU’s GDPR, the U.S. does not have one unified federal data privacy law. Instead, cloud storage compliance is shaped by a patchwork of sector-specific and state-level laws.
The key federal frameworks that apply depending on your industry are:
- HIPAA: Governs health data stored or processed in the cloud.
- GLBA: Applies to financial institutions handling customer financial data.
- FERPA: Covers educational records stored digitally.
- FTC Act Section 5: Broadly prohibits unfair or deceptive data practices.
If your cloud storage involves any of these data types, those regulations follow the data, regardless of which cloud provider you use.
State Privacy Laws Add Another Layer Of Obligation.
Several U.S. states have passed their own comprehensive privacy laws, and they apply to cloud-stored data, too.
| State | Law | Effective |
| California | CCPA / CPRA | 2020 / 2023 |
| Virginia | VCDPA | 2023 |
| Colorado | CPA | 2023 |
| Texas | TDPSA | 2024 |
| Florida | FDBR | 2024 |
If your cloud storage holds data belonging to residents of these states, their laws apply, even if your business is based elsewhere.
A company headquartered in Ohio storing data from California residents is subject to CCPA. Location of the business does not override the location of the user.
Your Cloud Provider Is A Business Associate, Not A Legal Shield.
Many businesses assume that once data is handed off to a cloud provider, legal responsibility shifts with it. That is not how it works.
Under HIPAA, for example, cloud providers handling protected health information (PHI) are classified as Business Associates. You are required to have a signed Business Associate Agreement (BAA) in place before storing any PHI with them.
More broadly, your relationship with a cloud provider should always include contractual clarity on:
- Who owns the data
- How it is encrypted at rest and in transit
- What happens to the data if the contract ends
- How breaches are reported and within what timeframe
Without these terms in writing, your business carries the full legal risk.
The CLOUD Act Changes The Picture For International Storage.
The Clarifying Lawful Overseas Use of Data (CLOUD) Act, passed in 2018, allows U.S. law enforcement to request data stored by U.S.-based cloud providers, even if that data is physically located on servers overseas.
For U.S. companies using American cloud providers to store international customer data, this creates a direct tension with GDPR and other foreign privacy laws.
A government request under the CLOUD Act could put you in violation of EU data transfer rules simultaneously. According to the IAPP, this conflict remains one of the top unresolved compliance challenges for multinational companies using U.S. cloud infrastructure.
Encryption And Access Controls Are Legal Risk Reducers.
Strong technical controls don’t just protect against breaches; they can limit legal liability when something goes wrong. Key practices include end-to-end encryption, role-based access controls, audit logs, and regular third-party security assessments.
A 2023 IBM report found that breaches involving stolen credentials cost U.S. companies an average of $4.62 million. That’s higher than the overall breach average.
Access control isn’t optional hygiene. It’s financial risk management, and in a cloud environment, it’s also your first line of legal defense.
