How to anonymise PII in non-production SAP S/4HANA systems – and comply with GDPR

Is your SAP non-production system a security blind spot?

Your Chief Information Security Officer (CISO) is probably sleeping soundly, knowing your SAP S/4HANA Production system is fortified with multi-factor authentication (MFA), constant threat monitoring, and the tightest access controls available.

But there’s a critical question that keeps many SAP Security Managers and Data Privacy Officers awake at night: Your Production data may be secure, but what about your Test, Development, and Quality Assurance systems?

SAP’s Data Processing Agreement (DPA) for their Cloud Services clearly stipulates that customers cannot store Personally Identifiable Information (PII) in non-production systems. This is a security blind spot, and it’s where many compliance controls can be violated.

You may not realise that the response to both of these questions is a resounding ‘yes’:

• Does PII pertaining to customers, vendors, and employees need to be obfuscated in non-production systems? Yes it does!
• Does your PII data need to be anonymised or encrypted to maintain privacy for these stakeholders and safeguard your company from any formidable breach? Yes it does!

The reality is that non-production systems are indispensable for innovation. Developers and consultants need access to real-world data structures to test new configurations, resolve production issues, and build new functionality. But this essential work also introduces risk.

Questions you may have come across in your company:

• Have your Audits and Reviews identified concerns around compliance with GDPR?
• Are your non-production systems accessed by consultants having developer or configuration access to resolve issues or perform changes?

If the answer to any of these is ‘Yes’, then your current non-production security strategy is putting you at risk of regulatory fines and potential brand damage.

The problem is clear: You need functional, realistic data for testing, but you cannot afford to expose real PII. This is why a simple data copy is no longer enough. The shift to S/4HANA and the rise of data privacy laws demand a smarter approach.

In this blog, we break down three critical risks in your non-production environments and introduce a proven solution for achieving GDPR compliance while preserving essential data utility.

What are three risks in SAP non-production environments?

The security mindset that works for a locked-down Production system doesn’t apply to Development, Testing and Quality Assurance environments. These systems – while vital for operations – are inherently more vulnerable because they require greater flexibility, more access, and often contain copies of real data.

Risk 1: The consultant and developer vulnerability

One of the most immediate risks you face is the need for temporary or external access to your non-production environments.

Whether it's an external third-party consultant, support teams at your System Integrator (SI), a developer with debugging access, or a system administrator, these roles require highly permissive access to troubleshoot and configure your systems.

The danger: When these individuals access a non-production system containing true unmasked PII, you instantly create a security loophole. A simple security lapse or accidental exposure can lead to a significant data privacy breach, and because it's in non-production, they can be outside the robust controls of your Production environment.

Risk 2: GDPR and data privacy violations

The regulatory landscape – particularly with GDPR and similar data privacy laws – makes no distinction between Production and non-production systems when it comes to the legal obligation to protect personal data.

The danger: If a regulator investigates and finds real employee or customer PII (names, salaries, addresses, etc.) exposed in a non-production sandbox, the potential fine is the same as if it occurred in the live system. Intelligent anonymisation and scrambling are the only ways to preserve data usability for testing while completely removing the compliance risk.

Risk 3: The data sprawl complexity

As you move to S/4HANA, your system landscape often becomes more complex. You might have multiple Development, Test, and training systems, potentially across various cloud or on-premises platforms. Your SAP system is probably interfacing with a myriad of other systems.

The danger: Data is copied, refreshed, and moved across this sprawling landscape constantly. Ensuring that every single non-production instance – from the newest sandbox to the oldest QA environment – is compliant and free of PII manually is practically impossible. This data sprawl significantly increases your attack surface, creates inconsistencies, and complicates compliance audits. It’s a guaranteed way to increase audit concerns:

The complexity of the modern SAP landscape demands an automated, reliable, and central mechanism to manage data privacy.

What’s the answer to your PII challenges in SAP? Data Secure

The problems outlined above aren’t solved by standard SAP tools or simple manual processes; they require a dedicated, intelligent solution built for the complexity of the SAP landscape. This is where Data Secure steps in, closing the non-production security gap.

Data Secure doesn't just manage data; it transforms it, ensuring that compliance is met without sacrificing the data utility necessary for productive development and testing.

Benefit 1: Maintaining data consistency for realistic testing

The biggest challenge with traditional data scrambling is maintaining data integrity. If you scramble an employee's name in one system but not their related financial records in another, your testing is invalid. Data Secure overcomes this with sophisticated data transformation.

• Persistent scrambling: PII is consistently scrambled across all linked systems and clients in your SAP landscape (e.g., Development, QA, Sandbox). ‘John Smith’ is always transformed to the same fake, yet realistic name everywhere, ensuring referential integrity and valid test results.
• Data accuracy and usability: The scrambled data remains logically valid. Date fields remain dates, phone numbers retain the correct format, and email addresses are functional. This preserves the functional realism of your testing while entirely removing the risk of exposing real PII.

Benefit 2: Removing risk with irreversible anonymisation

Unlike basic encryption, which can be reversed by a privileged user, Data Secure applies irreversible masking methods to sensitive fields. This means that even the most privileged consultant or developer working on your non-production system will only ever see fictitious, non-personal data.

This directly addresses Risk 1: The consultant and developer vulnerability by making the data worthless to an attacker; while keeping it perfectly useful to a developer. You get to maintain developer access without incurring PII risk.

Benefit 3: Effortless compliance and audit trails

Addressing the questions raised by your audits requires verifiable proof of your data protection methods. Data Secure doesn't just scramble the data; it provides the robust framework necessary to demonstrate compliance.

• Audit-ready reporting: The solution provides detailed reports and audit trails that prove what data was scrambled, when, and how. This evidence is invaluable when responding to a regulatory body or an internal audit, directly answering their concerns about GDPR adherence. This addresses Risk 2: GDPR and data privacy violations.
• Focused approach: Data Secure integrates seamlessly with Data Sync Manager’s data subsetting capabilities, meaning you can reduce your data footprint. Less data in non-production inherently means less data to secure, reducing Risk 3: The data sprawl complexity and significantly cutting storage costs and system refresh times.

Data Secure allows you to confidently say YES to innovation, and NO to non-production security risks.
