Adapting product architecture to EU AI Act requirements

How to adapt AI product architecture to meet EU AI Act requirements. We explore the transition to Compliance by Design for successful export to the EU market.

As 2026 approaches, when EU AI Act requirements become a mandatory "license to operate" for any software in the European market, Ukrainian product companies face a strategic choice. The era of reactive compliance, where legal risks were addressed solely by updating "Terms of Service," is ending. Now, regulatory compliance is a fundamental engineering and architectural task.

Attempting to export an AI system without built-in control mechanisms risks not only the loss of European clients but also colossal financial sanctions. A product with an opaque architecture loses investment attractiveness and the valuation of its intellectual property (IP). To maintain export margins, Ukrainian businesses must transition to a "Compliance by Design" concept—designing AI architecture with built-in transparency, security, and audit mechanisms.

Regulatory barrier 2026: Why the EU AI Act is a technical challenge, not a legal one

Engineering teams often perceive regulatory requirements as a purely legal layer. However, lawyers cannot implement data tracking or model logging into code. Most commercial B2B solutions with AI elements impose strict obligations regarding training set management and resilience against cyberattacks.

According to the Cisco AI Readiness Index 2025, only about 13% of organizations globally are classified as "Pacesetters" in AI readiness. This gap indicates low technical market preparation. For Ukrainian exporters, this means that if the product architecture does not allow for verifying data lineage or decision-making logic, the European regulator will block market access.

The "black box" trap: Why traditional AI architecture will not pass an audit

Most modern AI products were built for rapid market entry. Models were trained on chaotically collected datasets, and their operational logic remained a "black box." Under European regulation, such architecture is unacceptable.

For companies building corporate solutions with AI elements, it is critical to rely on a reliable system foundation. For example, using the UnityBase platform (a joint development by companies in the Intecracy Group, where InBase is a key but not the only developer) provides built-in audit trail mechanisms, row-level security (RLS), and role-based access control (RBAC). This allows developers to isolate AI services from critical corporate data while focusing on the security of the models themselves.

Compliance by design: Four steps for adaptation using the NIST AI RMF framework

To structure the AI risk management process, leading engineering teams use the NIST AI RMF 1.0 framework. It offers four key functions:

  • Govern: Creating a risk management culture. Defining data access policies and responsibilities.
  • Map: Identifying the context of AI operations. Classifying models, the data they consume, and the processes they influence.
  • Measure: Developing metrics to assess risks, bias, and model resilience.
  • Manage: Implementing tools for incident response.

Note: Technical frameworks are tools for risk management, not for absolute elimination. Their implementation does not guarantee automatic receipt of an EU AI Act legal certificate—compliance always requires a separate legal assessment.

The technological stack of compliance: Data tracking, red teaming, and monitoring

Practical implementation requires integrating specific engineering practices into the daily development cycle:

1. Automated data lineage tracking

Every step of data preparation must be logged in the CI/CD pipeline. The architecture must record the dataset version and applied filtering methods to provide EU auditors with transparency regarding algorithm training.

2. AI red teaming

AI models are vulnerable to specific cyberattacks. To identify vulnerabilities, engineering teams must conduct attack simulations using the MITRE ATLAS knowledge base of attacker tactics. This allows for strengthening the architecture before release to production.

3. Monitoring performance metrics (SLI/SLO)

Implementing monitoring for service indicators (SLI/SLO) for models allows for maintaining reliability standards. Using the concept of an error budget helps automatically stop model operation when its accuracy degrades.

An example of a systematic approach to integrating AI solutions is Softengi, which is certified to the international AI management standard ISO/IEC 42001:2023. Using AI consulting and development, the company helps integrate security standards into enterprise operational circuits. At the same time, ready-made modules, such as the AI Center from InBase, provide an LLM-agnostic architecture and automate data classification and extraction with high precision, which further structures information processing.

The economics of adaptation: How regular architectural reviews preserve capital

For CFOs and business owners, the key question is the cost of refactoring. Fixing architectural errors in production is significantly more expensive than preventing them.

Conducting regular architectural reviews (e.g., using the AWS Well-Architected Framework at each release cycle) allows for identifying risks before they become incidents. As confirmed by the Thoughtworks Technology Radar, engineering discipline, testing, and code review are fundamental for the secure delivery of AI solutions. Investments in these practices protect export margins and reduce the risk of multi-million dollar fines.

AI product architectural readiness scale for EU AI Act requirements
Readiness LevelArchitecture Description
Level 1: ReactiveModels are trained chaotically, data lineage is not recorded, and there is no monitoring of model behavior in production.
Level 2: FragmentedBasic logging is implemented, but there is no end-to-end data lineage; security is assessed only before releases.
Level 3: SystematizedArchitecture supports automatic data auditing; NIST AI RMF framework is implemented; risks are assessed regularly.
Level 4: OptimizedCompliance by Design: integrated automatic CI/CD model control, attack simulations via MITRE ATLAS, real-time SLI/SLO monitoring.

Transitioning from chaotic development to a "Compliance by Design" architecture is a strategic investment in stability, security, and maintaining your product's access to the European market.

FAQ

What technical requirements of the EU AI Act are critical for software architecture?

The most critical requirements concern end-to-end data lineage tracking, detailed logging of model operations for audit purposes, transparency of algorithm logic, and the integration of cybersecurity mechanisms and resilience against specific AI attacks.

How can we prove the security and transparency of our AI model to the European regulator?

It is necessary to implement automated documentation of the model lifecycle through CI/CD pipelines, conduct regular vulnerability testing (AI Red Teaming using threat databases like MITRE ATLAS), and ensure continuous monitoring of performance indicators (SLI/SLO) in production.

Is it necessary to completely rewrite the product architecture to obtain EU certification?

Not always. By using a modular approach and mature platforms (e.g., UnityBase for reliable data storage and auditing), you can isolate AI services and refactor only those components directly responsible for information processing and model decision-making.
