EU AI Act high-risk controls - are your AI governance tools ready?

TL;DR: The EU AI Act’s high-risk system obligations become operational on August 2, 2026, and the hardest requirements are continuous risk management, tamper-evident logging, human oversight, and AI-specific cybersecurity, according to WitnessAI. Compliance will fail where organisations treat the law as documentation work instead of evidence-producing governance across the AI lifecycle.

By the numbers:

• Tier 2 violations can reach €15 million or 3% of total worldwide annual turnover, whichever is higher.
• For a company with €10 billion in global revenue, that translates to €300 million.
• Nearly 70% of businesses report difficulty understanding their specific obligations under the Act.

Questions worth separating out

Q: How should organisations classify AI systems for EU AI Act compliance?

A: Start with intended use, not technical complexity.

Q: Why do AI governance controls fail when they are only documentary?

A: Because the EU AI Act expects operational evidence, not just policies.

Q: How do security teams know whether AI logging is good enough?

A: Logs should be tamper-evident, detailed enough to reconstruct inputs, outputs, and intervention points, and retained long enough to support review.

Practitioner guidance

• Define the high-risk AI inventory Create a single inventory of AI systems that may reach EU users, then classify each use case against Annex III and provider or deployer duties.
• Map runtime evidence to Articles 9 through 15 For each in-scope system, map the evidence you can actually produce for risk management, logging, documentation, human oversight, and cybersecurity.
• Assign named oversight and escalation owners Name the people who can monitor, override, interrupt, and report AI system behaviour, then test those roles in exercises.
