What enterprises actually ask you to prove.
Four guides on the security + compliance layer of AI applications. The threat model, the unsolved prompt-injection problem, where your data actually goes, what the EU AI Act / SOC2 / HIPAA / FedRAMP intersection looks like in 2026.
AI threat model
What can go wrong in an AI application — prompt injection, data leakage, model theft, supply-chain compromise. The structured way to think about it.
Prompt injection
Direct + indirect. Why it's unsolved. What mitigations actually work in 2026 (spoiler: defense in depth, not 'a better system prompt').
Data residency
Where your data goes when you call an API. EU vs US data flows. AWS Bedrock vs Azure OpenAI vs direct provider. What you can legally promise customers.
AI compliance
EU AI Act timelines. US Executive Orders. SOC 2, ISO 27001, HIPAA, FedRAMP intersections with AI systems. The compliance reality for 2026 builders.
