The Challenge

Marsstein builds an AI-native compliance automation platform. Organizations use it to automate GDPR gap analyses, generate data protection impact assessments, and maintain audit-ready documentation – tasks that previously required expensive consultants and months of manual work.

The problem: compliance automation means feeding sensitive data into AI models. Data processing records, employee information, vendor contracts – all of it flows through AI agents. For a platform that exists to help companies comply with GDPR, exposing that data to cloud AI providers without protection would undermine the entire value proposition.

Our clients trust us with their most sensitive compliance data. With MATVIS, we guarantee that this data is protected at every step.

– Jayson Chen, CEO, Marsstein GmbH

The Solution

Marsstein integrated the MATVIS AI Firewall into their platform architecture, placing it between their AI agents and the cloud AI models they rely on.

How It Works

Every request from Marsstein’s AI agents to external models passes through MATVIS first. When an agent processes a client’s data processing records – containing names, contact details, data categories, and legal bases – MATVIS detects and pseudonymizes all personal data before it reaches the AI provider. The AI model works with sanitized data. When the response comes back, MATVIS re-identifies the pseudonyms so the output is complete and accurate.

Marsstein’s AI agents process data from multiple clients simultaneously. MATVIS ensures no client’s personal data ever leaves the platform in the clear. Because MATVIS uses deterministic machine learning models, the same input always produces the same classification – Marsstein can demonstrate exactly how data protection works to their own clients and auditors

Key Results

>99.9%

Detection Accuracy

Personal data across client compliance documents – names, addresses, emails, IBANs, contract details – detected and pseudonymized automatically.

Compliance

by Design

Marsstein’s clients benefit from GDPR-compliant AI processing without any additional setup. Data protection is built into the platform, not bolted on.

Zero

Data Exposure

No personal data from client compliance documents reaches external AI providers unfiltered. Protection is enforced at the API layer, independent of AI provider behavior.
