Enterprise Data Room Requirements: The Questions Procurement and IT Will Ask

At a large company, choosing a data room is seldom the deal team’s decision alone. Corporate development or the legal team builds a shortlist, then IT security reviews the vendor, procurement negotiates the contract and the privacy office checks the data terms. Any of them can stop the process, and the most common reason is a requirement nobody asked about until the review began.

This guide sets out the questions each function typically asks, explains how our enterprise top 10 scores them, and states provider gaps only where our facts file records them.

Who reviews a data room in an enterprise?

The deal team tends to judge vendors on the last row; the other four rows decide whether the vendor can be used at all. Asking their questions first saves weeks.

What will IT security ask?

Identity comes first. Most enterprise security policies require that staff log in to business applications through the corporate identity provider, so that access is granted, reviewed and removed centrally. That means single sign-on.

Ask each finalist:

• Is single sign-on supported, through which protocols, and on which plan?
• Can external guests use two-step login while internal users use SSO in the same room?
• Is user provisioning automated, or must admins create and remove accounts by hand?
• Which attestation reports and certificates are current, and what do they cover?
• Will you complete our security questionnaire, and do you have a standard one already filled in?

Assurance is the second block. Our facts list ISO 27001 for 12 providers and a SOC 2 listing for all 18, with one covering the hosting infrastructure rather than the vendor’s own service. Ask for the documents themselves, not badges.

What will procurement and legal ask?

Procurement looks at the contract and the vendor as a business. Legal and privacy look at what the vendor may do with the data.

Multi-room administration is easy to overlook. A company running several acquisitions a year wants one contract, one admin console, reusable folder templates and consolidated audit exports, not a new vendor onboarding every time.

How does the enterprise list score these requirements?

The list reweights our six criteria for a large buyer: Data protection 30%, Diligence toolkit 30%, Deal support 22%, Checklist breadth 10%, Ease of adoption 5% and Cost predictability 3%. It then adds bonus points for the items IT and procurement most often require.

The bonuses explain most of the order behind Ellty. iDeals, Datasite and Intralinks each pair high protection and toolkit marks with ISO 27001, SSO and an enterprise focus. Intralinks, a long-established platform for regulated buyers, scores among the highest Data protection marks we give; its profile also records the gaps in our facts, no public API and no e-signature, and quote-only pricing. Ellty earns none of the bonus items; our facts list no SSO, no public API and no ISO 27001 for it, which an enterprise IT team should weigh directly. The Datasite vs Intralinks page compares the two most common enterprise finalists in detail.

Where do enterprise reviews most often stall?

Three points cause most delays. The first is single sign-on discovered late: the deal team picks a room, IT asks how staff will log in, and the answer is a separate password with two-step login. Some security teams accept that for a time-limited deal room with external guests; many do not. The second is the liability cap. Standard vendor terms often cap liability at fees paid, which can be a few thousand dollars against a transaction worth hundreds of millions, and legal will want it discussed. The third is the subprocessor list, particularly where AI features send document text to a model provider that has not been through the company’s own vendor review.

Each of these can be resolved, but not quickly. Raising them in the first vendor call, rather than after the deal team has chosen, is what keeps an enterprise selection inside a deal timetable.

What should be in the vendor review pack?

Ask every finalist for the same set of documents at the same time, so reviewers can compare like with like.

The feature checker filters all 18 providers on SSO, API, two-step login and the other checklist items, which is a quick way to see who survives the IT filter.
