Ask an AI vendor to prove its own security, and a good one will show you the architecture: where tenant isolation lives, what screens a file before it reaches the model, who verifies the rating. That’s the review IDC Quanta walked through in Five Questions to Ask Before You Trust an AI Vendor’s Security Claim.
There’s a second review most security teams skip. Every AI vendor runs on other vendors: cloud infrastructure, identity providers, monitoring tools, backup services. Their compliance claim is a chain, not a single link. If any vendor in that chain is weak, unverified, or simply unnamed, the vendor’s own SOC 2 report describes a foundation nobody actually inspected.
Four Questions for Your Vendor’s Vendor List
A security team doesn’t need a hundred-point audit to close this gap. Four questions do most of the work:
- Can you name every vendor in your security stack, by domain?
- Which certifications does each of those vendors carry, and can I verify them independently?
- What happens if one of those vendors fails a certification renewal?
- Who owns the relationship with each vendor, and how is that relationship reviewed?
A vendor with real architecture behind its claims answers all four without hesitation. A vendor that reframes the question (“we’re SOC 2 compliant, so this doesn’t apply”) is telling you it hasn’t looked.
What “Zero Trust” Actually Means Once You Name the Vendors
Most vendors describe their security stack as “zero trust” and stop there. That word does no work on its own. It becomes checkable the moment a vendor names who’s actually running each layer, and what’s actually at stake if one of them underperforms.
IDC Quanta’s stack, published in its Security Overview, names 24 vendors across 11 security domains: endpoint protection, identity and access, network security, monitoring, cloud security, and more. SentinelOne and JAMF handle endpoints. Entra ID and AWS IAM handle identity. Zscaler and Check Point sit in the network layer. Sumo Logic and 7AI, a 24/7 managed detection provider, staff the monitoring seat.
The Compliance Chain Nobody Audits
Here’s the harder question: does the vendor’s own infrastructure carry the certifications it claims to inherit? A vendor can be SOC 2 compliant on paper while running on infrastructure partners who aren’t, and the sales deck will never mention the difference.
IDC Quanta’s infrastructure runs on AWS (SOC 1, 2, 3, and ISO 27001), Azure (SOC 2 and ISO 27001, 27017, and 27018), and Snowflake (SOC 2 Type II, ISO 27001, and PCI DSS). The other tools in the stack, including Datadog, Grafana, and the identity and observability vendors, each carry their own SOC 2 certification. That’s the extended fourth-party layer, the vendors your vendor depends on, that most procurement checklists never reach. It asks whether that whole dependency chain is compliant too, with proof you can actually see, rather than stopping at the vendor’s own certificate.

Where Quanta Stands
Quanta’s own answers are published at a public link, so a security team can verify them independently instead of taking this piece’s word for it. The 24-vendor, 11-domain stack is named in the Security Overview, along with the certification each infrastructure and tooling partner carries. BitSight rates Quanta at 800 out of 900 as of July 2026, an externally verified number rather than a self-reported one. The vendor relationships behind that score sit with the same security team that owns tenant isolation and the pen-test cadence covered in the first piece, so the fourth-party review and the first-party review are never separated internally.
See IDC Quanta for Yourself
Compliance chains are only as strong as their weakest, least-verified link. A security review that stops at the vendor’s own SOC 2 report has checked one link and called it a chain. Ask for the vendor list next. Quanta’s is posted at trust.idc.com, verifiable in the time it takes to read this sentence rather than the weeks a typical security questionnaire takes to clear.
