What was said
What this says
Current to 10 Oct 26First of five security review sessions on 24 Oct 2025 for the open Enterprise proposal of £125,000. Nadia Osei wants written evidence for her capacity providers and will set no sign-off date until they have seen it.
What happened: Hannah Lowe held session one of five on 24 Oct 2025, covering architecture and data residency. Nadia Osei listed her open items, and Hannah committed to written answers, an annotated diagram and connector permission scopes.
Customer view: Nadia needs evidence her capacity providers can audit, and pressed on where the AI model processes data. Hannah did not give a firm answer and left it for the security side to confirm.
Commercial: The review supports the open Enterprise proposal, total deal value £125,000, against Growth at £44,000 today. The expected close of 31 Dec 2025 is B-Brain's own estimate, and Nadia will not set a date.
Watch: Staff access mechanism, model processing location and encryption are all pending in writing. The EU or US residency add-on may be unnecessary if the Snowflake region suffices.

Next steps
Current to 9 Oct 26- Hannah Lowe to send the annotated architecture diagram and a short summary of what was asked and answered.
- Hannah to deliver written answers on model processing, staff access (marked pending), encryption with document version, and the nightly refresh region.
- Nadia Osei to confirm Fenmoor's Snowflake region from the customer side.
Risks
Current to 9 Oct 26- Nadia will set no sign-off date until the capacity providers have seen the evidence, so the expected close of 31 Dec 2025 may slip.
- Where the AI model processes data is unanswered and is the point Nadia most wants in full.
- Several written answers are still pending, and a slow or vague reply could stall the Enterprise proposal.
Opportunities
Current to 9 Oct 26- The Enterprise proposal of £125,000 is open and moving through security review at the customer's pace.
- A dedicated EU or US data residency add-on could apply if Fenmoor's requirement is stricter than its Snowflake region.
Transcript
Hannah Lowe NoneHello Nadia, can you hear me? Good. Thanks for joining, and good afternoon. Before we start – is there anything you most need to know from today, so I can make sure we cover it?
Nadia Osei NoneHello Hannah, yes, I can hear you well. Thank you. Since this is the first of the sessions, I would like to list what I have as open items, so that we agree the scope. One, the architecture and where the data lives. Two, data residency. Three, access control and how it is administered. Four, logging and what I can show an auditor. I understand we will not get to all of them today.- Hannah Lowe NoneThat matches my understanding. Session one of five is architecture and data residency, so numbers one and two properly today. Access control and logging are in the later sessions, but I'll note anything you want to flag early so it doesn't get lost.
- Nadia Osei NoneThat is fine. For the audit trail, I should say I am taking notes and I will send you my version of the record afterwards. Could you confirm that you are happy for the notes to go into the questionnaire?
- Hannah Lowe NoneYes, of course. And I'll put anything I say in writing as well, so you're not relying on a verbal answer. That's how I'd prefer it.
- Nadia Osei NoneGood. Then let us begin with architecture. In plain terms, where does B-Brain sit in relation to our systems?
- Hannah Lowe NoneThe short answer is: inside your own Snowflake account. The longer answer is this. The brain isn't a separate service that you send your data to. It's built and run inside your Snowflake account, so the data you already hold there is where the brain's data sits as well. We don't hold a copy of your data in an environment of ours.
- Nadia Osei NoneCan you evidence that? I would like to see a diagram, and not only a description.
- Hannah Lowe NoneYes. I have an architecture diagram that shows the boundary – your Snowflake account on one side, the source systems on the other, and the connectors between them. I'll share it after this call, and I'll annotate where each type of data goes and which side of the boundary it's on. To be precise, I'd rather you had it labelled than have to infer it.
- Nadia Osei NoneThank you. Now the sources. Which of our systems does it read from?
- Hannah Lowe NoneFor Fenmoor it reads from the sources that were agreed in your order form – broadly your CRM, the helpdesk for claims tickets, and the submissions and bordereaux data. I'd rather not recite a list from memory, because I don't want to say something that's out of date. I'll take the connector list from the order form and put it in the pack with the exact source for each one.
- Nadia Osei NoneI appreciate that. Is access to those source systems read-only?
- Hannah Lowe NoneThat's one I want to answer carefully. The connectors are designed to read from the source and write into your Snowflake account. But whether it's strictly read-only depends on the permissions that the connector is granted by your admin in each source system. So the control is partly ours and partly yours, and I'd like to document exactly which scopes each connector requests, rather than say 'read-only' as a blanket statement.
- Nadia Osei NoneThat is a better answer than the one I usually receive. Please add the permission scopes per connector to the questionnaire.
- Hannah Lowe NoneWill do. I'll make a note of that now – scopes, per connector, in the questionnaire.
- Nadia Osei NoneNow, I will ask about the people at B-Brain. Who on your side can see our data?
- Hannah Lowe NoneRight, and this one belongs partly to the next session on access control, but let me give you the outline. Because the brain runs in your account, access by anyone at B-Brain depends on what your account administrators grant to us. Nobody at B-Brain has standing access to your data by default. When we need to support something, it's through access that you grant.
- Nadia Osei NoneBy default. And in practice? When an incident is raised?
- Hannah Lowe NoneIn practice, for an incident, we'd ask for access, and you'd grant it for the duration. What I don't want to do is describe the mechanism in detail today without checking it, because I'd want to be sure of the exact steps. I'll confirm that with a colleague on our security side and include it in the written answer for session three.
- Nadia Osei NoneThat is acceptable. Please mark it clearly as pending, so I do not record it as confirmed.
- Hannah Lowe NoneYes. Pending, with an owner and a date. I'll send you that with the diagram.
- Nadia Osei NoneNow data residency. This is the item our capacity providers care about most. Where is our data held, geographically?
- Hannah Lowe NoneBecause the brain sits inside your Snowflake account, the data lives wherever that account is hosted. So residency follows your Snowflake region. I don't want to guess what that region is for Fenmoor – you'll know it better than I do, or your account administrators will.
- Nadia Osei NoneI will confirm the region from our side. But I would like to hear from you that nothing leaves it.
- Hannah Lowe NoneUnderstood. So to be precise: the brain's storage and processing run inside your account, so they're in your region. The part I'd want to qualify is anything involving the AI model that answers the questions. Where that processing happens, and what's sent to it, is a separate question from where the data is stored, and I don't want to blur the two.
- Nadia Osei NoneYes. That is exactly the part I was going to ask. Please answer that one in the questionnaire, in full, not in summary.
- Hannah Lowe NoneI'll do that, and I'll check the wording with the security side first, so it's right the first time. Can I ask – is that question coming from your capacity providers specifically, or is it your own requirement?
- Nadia Osei NoneBoth. The capacity providers audit our supplier reviews. They will want to see that I asked the question and what evidence I received. I will not set a sign-off date until they have seen the pack.
- Hannah Lowe NoneThat's completely reasonable, and I'd rather we didn't put a date on it either. We'll take the sessions at your pace.
- Nadia Osei NoneGood. Is there a different arrangement available for residency, if our requirement is stricter than the default?
- Hannah Lowe NoneThere is. There's a dedicated EU or US data residency add-on, which is for customers who need the data in a specific region. For a UK customer whose own Snowflake account is already where you want it, you may not need it, but I'll say that in writing once you've confirmed the region. I wouldn't want to recommend something you don't need.
- Nadia Osei NoneUnderstood. Can I ask – this review is for the larger arrangement, not the current one?
- Hannah Lowe NoneCorrect. You're on Growth today at forty-four thousand a year. The security review is part of the proposal for Enterprise, which is the expansion that's open at the moment. The total deal value on that proposal is one hundred and twenty-five thousand pounds. I'm not the commercial owner of it – Priya is – but I wanted to be clear about why we're doing this review.
- Nadia Osei NoneThank you. And the timeline on your side? I have seen a reference to the end of the year.
- Hannah Lowe NoneThe expected close in our system is Wednesday 31 December 2025. But that's an expected date on our side, not a commitment, and it's very much subject to your review. If your review needs longer, the date moves, not the review.
- Nadia Osei NoneThat is the right way round. Thank you.
- Nadia Osei NoneLast item for today from my list. Encryption. At rest and in transit.
- Hannah Lowe NoneI'll be careful here, because I don't want to overstate a control. What I can say confidently is that the data sits inside your Snowflake account, so the storage controls are the ones that account has. In transit, between the connectors and your account, I'd want to give you the exact configuration rather than a general statement. I'll include it in the questionnaire with the source for it, and you can compare it with what you need.
- Nadia Osei NonePlease. I will need that in the questionnaire, with the version of the document it comes from.
- Hannah Lowe NoneYes – document and version. Let me read back what I've got, so we both agree. One: the architecture diagram, annotated with the boundary and the data types. Two: the connector list from the order form, with permission scopes per connector. Three: the answer on B-Brain staff access, marked pending until I've confirmed it. Four: the written answer on where the model's processing happens. Five: the encryption configuration with sources. Anything missing?
- Nadia Osei NoneOne addition. Please include the region for the nightly refresh, as in, where that job runs. And I will send you the Snowflake region from our side.
- Hannah Lowe NoneGood, I'll add that as number six. Anything for the audit trail from today that you'd like me to send in a separate note?
- Nadia Osei NoneA short summary of what was asked and answered would be enough. I will attach it to my own record.
- Hannah Lowe NoneI'll send that this afternoon, with the diagram to follow when I've annotated it. Thank you for the clear list – it makes this much easier.
- Nadia Osei NoneThank you, Hannah. That was a useful first session. Kind regards, Nadia.
- Hannah Lowe NoneThanks, Nadia. Speak at the next session. Goodbye.
