What to check when an AI vendor embeds an outside safety evaluator

When an AI vendor lets an outside firm work inside its own trust boundary, with access to prompts, customer data and internal safety findings, the label "independent evaluator" is not enough on its own for a managed service provider to sign off on. MSPs whose customers run on AI-assisted platforms need a way to question that access before it is granted, not after an incident. This guide sets out what to ask, using a September 2026 deal between Anthropic and Accenture as the dated example that raised the question.

What to ask before approving evaluator access

Before signing off on any arrangement that gives an outside evaluator employee-level access to a vendor's systems, put these questions in writing.

• Request a data-flow map covering prompts, customer content, telemetry and red-team artifacts that the evaluator can see.
• Get contractual clarity on whether evaluation traffic can cross customer tenants, be reused for training, or leave an approved region.
• Confirm who owns residual risk after the evaluation — a vendor cannot outsource accountability by pointing to an outside evaluator.
• Ask for escalation paths, remediation SLAs and evidence access tied to the evaluator's findings.
• Check who funds the evaluator and whether it already has a commercial relationship with the vendor; that does not disqualify the arrangement, but it changes what "independent" means in practice.
• Treat multi-year investment figures as a stated intention, not a guaranteed budget or a cost that will be passed to customers.

The deal that raised the question

Anthropic and Accenture announced on 18 September 2026 that Accenture's AI safety unit, Faculty, will embed a team of evaluators inside Anthropic with employee-like access, to red-team models, run alignment assessments and test safeguards. Each company said it expects to invest at least $1 billion over five years in the effort, and Anthropic said it will fund Faculty's embedded work directly given the "importance and urgency" of the task.

Anthropic traced the arrangement to an essay its chief executive, Dario Amodei, published on 12 September 2026, arguing that the industry should "pace the frontier" because AI's growing ability to help build the next generation of AI could outrun the industry's ability to understand and control it. Anthropic said the deal is not exclusive: it is also in talks with the nonprofit evaluator METR, and Accenture may offer similar embedded-evaluator arrangements to other AI developers.

Why "external" is not the same as "independent"

An embedded evaluator with employee-level access can see prompts, customer content, telemetry and red-team artifacts that would otherwise stay inside the vendor's own perimeter — a materially deeper level of access than an outside audit at arm's length.

The Anthropic-Accenture deal also shows why funding and prior business ties matter to that judgment. Accenture and Anthropic already run the Accenture Anthropic Business Group, a joint unit formed in December 2025 to train about 30,000 Accenture staff on Claude, and Anthropic is now paying directly for Accenture's evaluator work. A social media post from Anthropic calling Accenture an "independent evaluator" drew a public correction on X for glossing over that relationship. Anthropic has said the arrangement does not reduce its own accountability for model safety, only makes it more verifiable — a distinction MSPs should hold vendors to in writing, not in a press release.

Documenting how a vendor-access decision like this was made and reviewed also matters for NIS2 and DORA evidence requirements. Audit-trail tooling such as Auris Comply keeps that kind of compliance record, so it is available when a regulator or a customer later asks why the access was approved.

What to do

1. Ask the vendor for a data-flow map before approving any embedded-evaluator access.
2. Add tenant-isolation, training-reuse and data-residency clauses to the contract, rather than relying on the announcement's wording.
3. Check the evaluator's funding source and any existing commercial relationship with the vendor.
4. Fix accountability for residual risk in writing, regardless of which evaluator is involved.
5. Log the decision and the vendor's answers as part of your compliance evidence trail.
6. Revisit the assessment if the evaluator relationship or its scope changes.
