I keep seeing companies buy AI the same way they used to buy normal SaaS: skim the security docs, review the DPA, sit through the demo, maybe ask about uptime, then move on.
That is not enough anymore.
When you’re evaluating a third-party AI system, the real problem is simple: you’re often buying a black box. You can see inputs and outputs, but not the logic inside. The vendor says the model is accurate, fair, secure, explainable, compliant. Fine. Show me the evidence.
That’s why I liked the practical framing here: move from trusting claims to testing behavior.
A few points really stood out to me.
First, vendor benchmarks are not your benchmark.
This is one of my biggest pet peeves in AI procurement. A vendor says they hit 97% accuracy. On what dataset? Under what conditions? With whose definition of success? If I’m evaluating an AI system for policy review, claims review, support automation, underwriting, hiring, or anything remotely consequential, I want to see performance on my data and my problem statement, not a polished benchmark from a curated environment.
That distinction sounds obvious, but a lot of teams still skip it.
Second, I liked the emphasis on black box testing.
If I can’t inspect the model architecture, training setup, or internals, I can still test the system like an engineer instead of admiring it like a prospect. Give it the same input multiple times. Check for consistency. Probe edge cases. Measure false positives and false negatives. See how it behaves on rare or messy inputs. Compare outputs across vendors using the same scenarios.
That’s not perfect transparency, but it’s a lot better than procurement by PowerPoint.
And honestly, this is the practical mindset more organizations need: if the box is closed, test the box harder.
Third, model cards and documentation matter, especially when the answer is “proprietary.”
I have no issue with vendors protecting IP. I do have an issue when “proprietary” becomes shorthand for “please stop asking questions.” If I’m onboarding an AI vendor, I want documentation around training data sources, coverage gaps, intended use, known limitations, evaluation methods, update cadence, and governance controls.
If they can’t produce a model card or equivalent documentation, that’s not a minor paperwork issue. That’s a signal.
The other part that I think people underestimate is that AI vendor risk is broader than security risk.
Security still matters, obviously. But AI assessment goes beyond “can this system be compromised?” It also asks:
- Does it actually do the job it claims to do?
- Is it consistent?
- Is it biased in ways that matter for this use case?
- Can we explain or challenge outputs?
- Is human oversight built in?
- Is there a kill switch or escalation path?
- Will our data be used to train shared models?
- What happens when we need to offboard?
That’s the difference between a standard vendor review and a real AI TPRM process.
One point I strongly agree with: data governance and privacy need to be front-and-center.
If a vendor is using customer inputs to improve shared models, that should not be hidden in vague language or buried in product defaults. For sensitive workflows—healthcare, finance, legal, HR, public sector—that’s a massive issue. Not an asterisk. Not a “we’ll review later.” A real issue.
The same goes for governance.
I’ve said this before in client work: most “AI governance” discussions are too abstract to be useful. Governance only matters if it changes decisions at onboarding time. Can the system be approved? Under what conditions? What tests are required? What evidence is mandatory? Who signs off? What monitoring happens after launch?
If governance doesn’t answer those questions, it’s just deckware.
What I appreciated here was the push toward a simple scoring framework that procurement, risk, privacy, security, and business teams can actually use together. Not because Excel is glamorous, but because a boring, shared scorecard beats a beautiful non-process every single time.
That’s the part many teams miss. You do not need a giant “AI transformation strategy” before you can improve due diligence. You need a workable intake and evaluation method with criteria like performance, explainability, fairness, privacy, security, operational reliability, human oversight, compliance posture, and contractual exit terms.
Practical > impressive.
My biggest takeaway:
If you’re buying AI, test it like it will fail in production—because eventually something will.
Not to block adoption. To make adoption real.
If I were tightening an AI vendor review process tomorrow, I’d start with three questions:
What is our actual problem statement?
What test data can we safely use?
What evidence would make us trust this vendor beyond the demo?
Everything gets clearer after that.
Curious how others are handling this right now—especially teams sitting between procurement, security, legal, and the business. Are you still relying mostly on questionnaires, or are you actually running structured black box tests before onboarding?
