IBM Technology. Explains the ingestion side of RAG and agents: preparing PDFs and other files so document structure, tables and layout survive into downstream retrieval. That supports the article's warning that RAG quality and safety begin before embedding, especially when parsing complex business documents.
This is a strong document-processing companion, but it is not a complete security plan. It does not replace file allowlists, malware scanning, permission metadata, retention/deletion behavior, source ownership or ingestion audit logs.
Understand why document parsing, structure preservation and ingestion quality gates matter before building RAG over PDFs and mixed file formats.
Basic RAG architecture, embeddings, chunking and the difference between clean text documents and messy PDFs or office files.

A cloud-vendor-specific complement to the Macquarie specialization: AWS's own Generative AI Security Scoping Matrix, OWASP Top 10 for LLMs, and MITRE ATLAS, walked through governance, legal, and compliance controls for five different AI deployment scopes — from consumer apps to self-trained models. Not GDPR-specific, but a genuinely practical advanced pick for teams whose AI workloads actually run on AWS and need concrete data-governance and compliance controls, not just theory.

The advanced, most explicitly on-target answer to our GDPR × AI gap: a three-course specialization from Macquarie University's Cyber Security Hub that goes from GDPR/CCPA fundamentals and privacy-by-design, through privacy impact assessments, to a dedicated third course on securing AI systems against adversarial attacks and model leakage. Genuinely bridges 'GDPR compliance' and 'AI security' rather than treating them as separate topics.

The rare AI Act course written for the companies the Act actually reaches: SMEs adopting AI, not the labs building it. Hosted on the European Commission's own skills platform, it pairs the legal side — roles, obligations, risk classification — with the security side (prompt injection, data leakage, supplier due diligence) that most compliance courses skip. For an Estonian SME deploying AI, this is the practical starting point.
