Ask a vendor if your data is safe and you’ll get a yes. Every vendor says yes. In IDC’s advisory conversations with enterprise security teams, that’s the pattern that comes up again and again: the review process collects reassurance. It rarely collects evidence.
Enterprises that get this right don’t stop at a compliance label. They check for automated evidence and audit trails. They look at model monitoring and explainability. And they weigh a vendor’s actual implementation track record: real deployments, real customers willing to go on record. That’s exactly the review your own IT and security team will run on any AI vendor before signing off, whether that vendor is IDC or anyone else.
The Review That Isn’t a Review
A typical vendor questionnaire asks:
- Do you encrypt data at rest?
- Do you have SOC 2?
- Is there an incident response plan?
These are yes/no questions, and yes/no questions get yes/no answers, regardless of whether the underlying control actually holds up under pressure. A security review that can be passed with a checklist only proves one thing: someone filled out a form correctly.
What “Compliant” Actually Means Depends on Who’s Asking
SOC 2 Type I confirms controls exist on a given day. Type II confirms they held up over a period of months. Both show up as “SOC 2 compliant” on a sales page. Neither tells you whether tenant data can bleed across customer environments, whether prompt injection is screened before it reaches a model, or whether your data trains anything. Compliance frameworks are a floor, not a finding.

Architecture Beats Attestation
The security teams that get this right stop asking whether a vendor is compliant and start asking to see it. Show me the encryption key management setup. Show me where tenant isolation is enforced: application-layer controls that keep one customer’s data from ever touching another’s, not just a policy written down on paper. An architecture diagram is harder to fake than a checkbox. Then ask what happens to an uploaded document in the sixty seconds before it reaches the model. Is it screened for prompt injection, meaning malicious instructions hidden inside the file itself, before the model ever sees it?
Five Questions That Change the Conversation
Five questions is a short list on purpose. Security teams don’t have time to run a hundred-point audit on every AI vendor pitching them this quarter.
- Where, specifically, is tenant isolation enforced?
- What happens to a file between upload and model ingestion?
- Is customer data used to train any model, yours or a third party’s?
- Who verifies your security rating, and how often?
- What’s your actual pen-test cadence, confirmed against the audit log rather than the sales deck?

Where Quanta Stands on Those Five Questions
Your own IT and security team will ask us these same five questions before Quanta clears procurement, so we might as well answer them here. And yes, we’re aware of the obvious catch: IDC also owns Quanta, so treat this section exactly like we just told you to treat every vendor’s answers. Verify it. Every spec below is published at trust.idc.com and open for a security team to check.
- Tenant isolation is enforced at the application layer. Token-derived identity and SQL scoping keep one customer’s data invisible to every other Quanta user.
- Every file uploaded to Quanta passes malware scanning and prompt-injection detection before it ever reaches the model. That’s the same sixty-second window this piece just asked every vendor about.
- Customer data trains nothing. Not Quanta’s models, not a third party’s. That’s a permanent commitment, built into the platform rather than a setting anyone could quietly change.
- Who verifies the rating? BitSight does, continuously. Quanta scored 800 out of 900 as of July 2026. SOC 2 Type I is compliant today. SOC 2 Type II and ISO 27001:2022 are both actively in progress.
- The pen-test cadence is confirmed against the audit log: annual third-party testing plus continuous vulnerability scanning, backed by a 24-vendor, 11-domain zero-trust stack with a monitoring team watching around the clock.
The Path Forward
None of this requires a bigger budget or a longer questionnaire. It requires asking for evidence. Vendors with real architecture behind their claims will show you exactly where each control lives, Quanta included. Pointing back to the checklist is what’s left when there’s nothing else to show. to show.
