Artificial Intelligence (AI) – Testing & Certification of AI Security

Contact us now

Trustworthy AI – TÜVIT tested!

AI technologies are increasingly part of all areas of our everyday lives. This increases the risks posed by error-prone AI systems, data misuse, and cyber attacks.

We support you on your way to trustworthy AI: Our experts accompany you throughout your development process and carry out detailed analyses (e.g. of the chosen model design) and tests (e.g. robustness, bias, explainability) of your AI systems. Subsequently, a certification can attest the technical security features of your AI.


  Think one step ahead

AI regulation is coming. With AI testing & certification, you can already optimally prepare yourself for future requirements.

  Show responsibility

With AI testing & certification, you fulfill your corporate responsibility and demonstrate the high importance of AI security.

  Better safe than sorry

External testing helps to detect and eliminate potential security vulnerabilities at an early stage.

AI Act: regulations for artificial intelligence

The Artificial Intelligence Act (AI Act) is intended to regulate artificial intelligence in future and strengthen trust in AI. Who is affected by the AI Act, what requirements it entails and what the current status is.

What are potential problem areas for artificial intelligence?

Artificial intelligence (AI) can be used to solve many data-driven problems more efficiently or faster than traditional software development. Despite all the advantages, however, its use always leads to additional sources of error, which must be considered appropriately as part of a risk analysis.

Robustness: AI systems that use machine learning usually have a robustness weakness: Even minor changes to the input can lead to incorrect classification.

Explainability: Another problem area of AI is the lack of explainability or transparency of decisions made by AI systems. In turn, this can have an impact on fairness.

Bias: Using artificial intelligence does not make bias disappear. This is because machines can also make discriminatory decisions (machine bias).

Our services for your AI security

We support companies already during development, and perform analyses for AI systems. Depending on customer requirements, subsequent certification of the technical security features can take place.

(Development-accompanying) pre-checks with regard to problem areas & solution approaches

Scoping & gap analyses for AI testing/certification

Theoretical analyses (development process, model design)

Security and safety analysis with special test software

AI certification process

Once our testing is complete, we can certify the security features of your product in our Trusted Product scheme. The certificate documents the results of the tests performed. The test report also provides a corresponding, structured classification of these results in the overall context.



Kick off workshop, definition of assets & threats, definition of valid input/output ranges, derivation certifiable requirements ("Technical Security Requirements")


Analysis & Derivation of Test Plan

Detailed review of the model architecture, derivation of a test plan, calibration of test tool for the defined tests 



Testing of the model using test tool, spot check validation of the results



Documentation & Certification

Documentation of results & issuance of evaluation report

If all requirements are met: issuance of certificate

Main points of AI examination & certification

Security / robustness
(robustness testing)

Is the AI safe and secure against attacks, accidents and errors? 

(explainability testing)

Are decision-making and the functioning of the AI transparent and comprehensible?

(bias testing)

Are the decisions made by the AI fair to all parties?

FAQ – Frequently Asked Questions

Is AI certification already possible?

Although AI-specific laws, norms and standards are still not here, it is already possible to certify properties of AI systems.

Once our testing is complete, we can certify the security features of your product in our Trusted Product scheme. The certificate documents the results of the tests performed, and the test report provides a corresponding, structured classification of these results in the overall context.

What are examples of a robustness weakness?

AI systems that use machine learning usually have a robustness weakness: Minor changes to the input lead to incorrect classification. This can have far-reaching consequences. If AI is used in camera-based recognition of traffic signs, e.g. rain or snow can cause a stop sign to be recognized as a right-of-way sign.

However, it is important to consider not only natural phenomena (such as the weather, pollution, etc.), but also deliberate manipulation by attackers. A small, specially prepared sticker on the stop sign or a large poster in the background of the sign can be deliberately used by attackers to deceive the AI.

This is where our robustness analysis comes in: We systematically test your system for these vulnerabilities before it goes into circulation. This allows you to toughen up your AI system appropriately during development, thus minimizing malfunctions in later use.

What are the benefits of certification?

Certification ensures that your customers can trust your AI system.

Which testing tools can be used to test AI? Which tools does TÜVIT use?

There are various software products for performing security audits of AI. It is not possible to give a general answer as to which is the most suitable for a particular application; hence this will be part of the initial phase of our testing service. TÜVIT always uses a testing tool developed in-house for its tests, but can also make use of external testing tools.

Are you already using with testing software “XYZ”, and would like to have these results verified by an independent body?

No problem: We can also integrate third-party tools into our audit process, as long as we consider them suitable. Our proprietary TÜVIT testing tool is then used as a reference for calibration and approval of the tests.
