I got a message from our legal team a few months ago.
"Can you fill out the AI section of our cyber insurance renewal?"
There was an AI section. A full page of questions about data flows, anonymisation layers, LLM provider policies, and whether sensitive data was leaving our environment.
Nobody told engineering this was coming. And honestly, we were not fully prepared to answer it cleanly.
What Changed in 2026
Cyber insurers added AI Security Riders to renewal questionnaires this year. The core question they are asking is simple: what happens to sensitive data when it flows through your AI systems?
For most teams, the uncomfortable answer is: it goes to a third-party LLM provider's servers. Potentially logged. Potentially retained. Outside your direct control.
A mid-size accounting firm learned this the hard way — ransomware attack, active policy, claim denied because the declared security controls were not actually in place. Over $300,000 in uninsured losses. The same logic now applies directly to AI data handling.
The Fix: Anonymise Before Inference
The control that satisfies the AI Security Rider requirement is local redaction. Before data touches the model, a pre-processing layer strips sensitive entities — names, figures, account numbers, anything regulated. The model works on the clean version. Raw data never leaves your environment.
raw_doc = load(input)
clean_doc, map = anonymiser.process(raw_doc)
output = llm.analyse(clean_doc)
final = map.restore(output) # optional
Build this layer provider-agnostic so it survives model switches. When it exists and is auditable, the renewal questionnaire becomes easy to answer honestly.
Questa AI has this built into their enterprise platform. Their full breakdown of what AI Security Riders actually require is worth reading before your next renewal:

The Bigger Picture
This is part of a broader shift. The LinkedIn conversation on privacy-first LLM architecture framed it well. The enterprise risk angle is tracked in The Sovereign Stack on: The Cyber Insurance Clause That's About to Catch Every AI-Adopting Enterprise Off Guard

All pointing to the same conclusion: anonymise-before-inference is no longer optional. It is the baseline underwriters, regulators, and enterprise clients are all expecting to find.
Engineers decide whether that layer gets built. That decision now shows up on insurance forms.
Build it deliberately.
