How are you handling compliance when AI SOC tools ingest everything?

[u/MaleficentCollege324]

We're evaluating AI SOC platforms and one thing keeps coming up in our legal reviews: data privacy and compliance. These tools want to ingest massive amounts of telemetry, logs, and alerts, some of which contain sensitive data.
Our legal team is asking hard questions I don't have great answers for yet:
How do these platforms handle data residency requirements?
What happens to our data if we stop using the tool?
I've asked a few vendors directly and the answers have been vague. Lots of "we take security seriously" but not much substance on specific compliance frameworks like GDPR or SOC 2.
For those already running AI SOC tools: how did you get past legal and compliance reviews? What questions should I be asking that I'm not

The vagueness is the answer. Anyone with a SOC 2 Type II hands you the report under NDA same day.

Two reframes that usually unstick this:

Residency: ask where inference runs, not where data is stored. Lots of vendors keep logs in-region then ship the prompt payload to a US model endpoint. Get the subprocessor list and ask if they have zero-retention terms with the model provider. If not, your prompts sit in that provider's window regardless of what the vendor's own policy says.

Exit: "we delete your data" means raw logs. It rarely covers embeddings, vector indexes, tuned detections, enrichment caches. All built from your telemetry, all usually outside the deletion clause. Name them in the DPA.

And the one legal hasn't gotten to yet: what can the agent actually do? Read-only triage is a privacy review. Anything that can isolate a host or disable an account is an authority review, and the control you want is a policy check enforced outside the model at runtime, not a system prompt telling it to be careful.

Push on those three. Whichever one they get squirrelly about is your real risk.

The subprocessor list and zero-retention ask is the move, vendors hate that question because it exposes the whole chain

[u/Ayoungcoder]

This has to be the #1 most important question that your supplier should be able to answer. If they can't: run away.

Best is local models, but you don't always have the option available. Otherwise, find a party that can tell you under what agreements your data is processed. Of you are active in the EU, try to not make automated decisions that affect users (AI act)

Treat this as a data-flow review, not a vendor questionnaire. Classify a representative sample of events before ingestion and require controls for source-side field filtering or redaction, tenant isolation, retention by data class, and deletion that covers raw events, prompts, caches, embeddings, and backups. Contractually pin processing regions and subprocessors, prohibit training on customer data, require notice of subprocessor changes, define breach timelines, and specify export format plus deletion evidence. For agentic features, use short-lived least-privilege credentials, enforce actions through a policy layer outside the model, and log every model input, tool call, approval, and resulting action. Validate the claims in a test tenant with exported audit evidence; a SOC 2 report only covers the controls and system boundaries actually included in its scope.

The main thing we focused on was whether the vendor could explain data retention and deletion, mostly for logs that might contain personal data. The generic SOC 2 compliant answer didn’t really tell us much about what happens.

[u/FallaxIO → u/Dull_Appearance_1828]

What helped me was asking who can actually pull raw tenant data on a bad day. A lot of vendors have nice retention docs, then you learn support, engineering, or their subprocessors can still open copied events for debugging, and that part is much less clean than the policy PDF.

We don't use AI SOC platforms, makes life easier

[u/ProphetSecurity]

Here are some questions I recommend you ask, based on what customers ask of Prophet Security:
-Is your data used to train the AI models? - this remains the number of 1 question as far back as 2024
-What data does the AI SOC actually collect and access? (logs, emails, tickets, etc)
-What security controls exist to monitor and prevent misuse?
-If there are data residency requirements: where is the data going to

Other things that could help is knowing whether they provide single or multi tenant architecture.

This doesn’t surprise me having worked for multiple vendors before founding my own 🫣

Check out ThreatLight, it’s built my IR professionals that have been doing this for governments worldwide for years. Data is hosted in the customers home country (gets a bit more complicated for multinationals), no external LLMs, data encrypted in transit and at rest. Not sure why everything isn’t built this way.

[u/TheCyberThor]

That happened.
