Test Data Compliance: Why Old Methods Fail and What Works Instead

Test data compliance efforts are falling behind development speed, creating a dangerous gap exploited by bad actors and scrutinized by regulators.

It's a wake-up call: Dev and test environments are under stricter regulatory scrutiny than ever. In my role as Senior Product Manager for Delphix, I regularly work with enterprise teams who are discovering this reality the hard way.

According to a 2025 McKinsey survey, the average organization scored between 2.2 and 2.7 (with a mean of 2.3 out of 4.0) on risk activities like using production data in testing environments — indicating this critical area of governance “Needs Attention.” On top of that, the volume of sensitive data in non-production environments continues to grow year after year, with 95% of organizations we surveyed saying it went up since last year. Most organizations still struggle with systematic monitoring, risk-based controls, and executive oversight.

In this blog, let's explore why test data compliance has become a critical business risk and what regulations now apply to your non-production environments. Then, I will break down how to build an audit-ready strategy that protects your organization.

Why Test Data Security Is Under the Microscope

The Shifting Regulatory Landscape

Test environments are a prime target for regulators and cybercriminals. Software development has reaped the benefits of CI/CD pipelines. But security controls haven't kept pace, leading to dangerous vulnerabilities for bad actors to exploit.

Unlike production systems, test environments often lack robust security monitoring and controls, making them easier targets for attackers seeking sensitive information. Multiple copies of production data are typically created for testing purposes. But because of that, organizations unintentionally expand their "attack surface", the number of places where breaches can occur.

These test environments often contain complete copies of production data, including sensitive customer information, financial records, and personal health data. This makes them fair game for compliance checks under data privacy regulations.

The rules that apply to production data now apply to test data as well. There's no hiding behind "it's just test data" anymore.

The Perfect Storm of Risk

Multiple Compliance Frameworks Colliding

Multiple regulations can hit you all at once. According to our 2025 State of Data Compliance and Security Report, 71% of organizations are subject to PCI DSS, 51% to GDPR, and 30% to CCPA, just to name a few.

But each regulation has different requirements, and some even conflict with others. Regardless, your test environments must ensure simultaneous compliance with all applicable frameworks.

Development Speed vs. Security Controls

Faster development cycles mean more data exposure. Teams deploy code several times throughout the day, and each deployment may create new data copies. More copies mean higher risks of data exposure.

But traditional security controls often slow down development. According to that same report, speed is the #1 barrier to protecting data in non-production. Your developers may create shortcuts to work around security measures to meet deadlines. This results in dangerous compliance gaps.

The Dangerous Silo Effect

Security and development teams work in separate silos. Security focuses on production systems, while development treats test data as "fake" and less important.

Neither team owns test environment compliance, creating gaps that regulators love to find. When something goes wrong, that is when finger-pointing begins.

What Laws Apply to Your Test Data?

Navigating the regulatory landscape for test data can feel like playing compliance whack-a-mole. Just when you think you've addressed one requirement, another regulation pops up with different, or sometimes even conflicting, standards. 

The challenge intensifies as each industry, geography, and data type brings its own rules, often with overlaps in regulations that add to the complexity. It’s a web of constantly evolving requirements that your organization will have to comply with. 

Understanding which laws apply to your test data is the first step in building a comprehensive compliance strategy.

Privacy Regulations

GDPR is a European regulation, but its impacts extend globally, and it hits hard. Fines can be up to 20 million euros or 4% of global turnover for severe cases. The right to be forgotten extends to test environments, and data purpose limitations apply everywhere your data lives.

CCPA protects consumer data in development and testing. You can’t escape California's reach just because the data you use is categorized as test data.

State privacy laws like CCPA create a growing puzzle of requirements. Each state adds new rules, and keeping up with each new regulation can become a full-time job.

Industry-Specific Mandates

PCI DSS is crystal clear: No cardholder data in non-production environments. Period.

HIPAA requires PHI safeguards in dev and test environments. Health data needs protection throughout all your systems.

DORA requires financial entities to conduct advanced testing on ICT systems, meaning your test data must be robust enough to validate resilience without introducing production risks. 

Data Sovereignty: The Geographic Puzzle

Cross-border data restrictions make compliance even more complicated. Some data is not permitted to leave certain countries, and cloud deployments can make this even trickier.

Residency requirements also mean sensitive data must stay in specific locations. Your global test environment strategy needs major rethinking to ensure compliance.

The Cost of Non-Compliance

Financial penalties hurt. Operational disruptions cost more. But the consequence that lasts the longest is reputational damage.

Modern cybercriminal groups like Scattered Spider have demonstrated how attackers specifically target non-production environments to access sensitive data. The 2023 MGM Resorts attack illustrates the devastating real-world impact. 

What started as a breach of their systems exposed personal information of 37 million customers — including names, addresses, phone numbers, email addresses, dates of birth, passport numbers, driver's license numbers, and Social Security numbers. 

The ransomware attack shut down Las Vegas slot machines and ATMs. MGM ultimately agreed to pay $45 million to settle the resulting lawsuits 

Sadly, data breaches are on the rise. According to our 2025 report, 60% of organizations have experienced data breaches or theft in non-production environments, an 11% increase from last year.

If your test data gets breached, customers would not care that it wasn't "real" production data. The headlines will read the same.

Customer trust disappears overnight. Research from Forbes indicates that 80% of consumers in developed nations cease their relationship with businesses following a compromise of their personal data. The everyday person does not understand the difference between test and production data. A breach is a breach in their minds.

Regulatory fines also follow quickly. Regulators do not give discounts for test environment breaches. The penalties are just as severe.

Worst of all, your reputation will take years to rebuild. Competitors can use your breach against you. Customers may choose other vendors. The business impact will last long after the technical fix.

Common Test Data Compliance Security Gaps

The "Copy and Pray" Approach

I’ve seen teams often choose this path because it is the path of least resistance. This occurs when they copy production data directly to test environments with no masking or poorly implemented masking.

Security between production and non-production environments stays inconsistent. This creates obvious weak points that attackers can exploit.

What Auditors Find

Missing access logs top the list. Data inventories don't exist. Uncontrolled and unmasked data spreads everywhere.

No documented data handling procedures exist, and incident response plans ignore test environments. These gaps can result in the severe penalties discussed earlier.

The "Empty Purse" Approach

But there is a better strategy to protect your data: Render your sensitive data useless to bad actors. It is not enough to just protect data — you have to de-risk it.

Recent attacks like Scattered Spider show how attackers think about valuable data. Picture yourself in the shoes of an attacker. An attacker typically only targets valuable data. If your test data has no value to them, they'll move on to the next potential victim instead.

There are two implementation approaches that work with this concept:

• Data virtualization eliminates production copies entirely. You mask data first, then you spawn copies of that masked data. This creates a "gold copy" approach.
• Advanced masking uses format-preserving de-identification. The data looks real, but contains no actual sensitive information.

Broken test data is holding you back. Automated masking, combined with virtualization, gives your teams compliant data, fast. Watch how it works with Perforce Delphix:

Your Audit-Ready Test Data Compliance Checklist: Implementation Roadmap

Navigating test data compliance can feel overwhelming, but it doesn't have to be. By following a clear, phased approach, you can systematically secure your non-production environments.

The following roadmap outlines a practical strategy to help you achieve and maintain compliance.

Phase 1: Discovery and Assessment

The first step is understanding what you're working with. You'll need to document all instances of sensitive data by creating a full inventory of sensitive information across all your systems. You should also note how your company currently handles this data.

Next, identify which regulatory requirements apply to each type of data. For example, a customer's credit card number follows different rules than a customer's email address. Once you know the rules, map out how data moves from your production environments to your test environments. This helps you see where sensitive information might have higher exposure risk. Tools like Delphix can automatically find and mask sensitive data for you, making the process much faster.

Phase 2: Quick Wins

Once you know where your data exists, you can start with some easy fixes.

Start by masking the data that poses the biggest risk. This means replacing sensitive information, like credit card numbers, with fictitious but realistic-looking data. Many tools come with built-in rules to find these common types of data.

But while these tools are great for standard data, you might have some custom sensitive fields unique to your company. You will need discovery tools that you can adjust to find and create custom masking rules.

In this phase, you should also establish access controls and monitoring rules to set up who can access the data and to watch for problems. It is important to create policies for how long you can keep test data before it gets automatically deleted. Finally, set up audit logs. This will log every action taken on the data, so you have a record of everything that happens.

Phase 3: Advanced Protection

Now that you have the basics covered, you can move on to more advanced solutions.

One powerful step is using data virtualization. This creates a virtual copy of your production data that uses very little storage space. More importantly, it allows users to work with it simultaneously without needing to make a full copy for each person. Virtualization can help keep your sensitive data more secure.

Another advanced step is using synthetic data generation. This creates completely new, fake data that looks and acts like your real data. But since it is not real data, it has no privacy risks. You should also automate compliance checks directly in your development pipelines. This means every time a developer changes code, a check runs to make sure no sensitive data is being handled improperly.

Finally, you can set up ephemeral environments. These are test environments that are created only when you need them and are then completely deleted after use. This ensures sensitive data will not be left sitting around after a test is done, drastically reducing compliance risk.
