The 13 tools, reviewed
#1 Firmex
Purpose-built data room, project or subscription · Canada · firmex.com
M&A Subscription 24/7 support
Firmex has run data rooms since 2006 and says its clients open more than 20,000 new rooms each year. It does one job and offers two ways to pay for it: a single-project room with fixed access time, or a subscription with unlimited projects and a named customer success manager.
- Pricing: Quote only. Quote-based; pay a one-time fee per project or an annual subscription sized by data volume. Free plan: none.
- Best for: Mid-size deals and repeat dealmakers
- Strengths: Document watermarks; Restricted viewing; User and group permissions.
Where it falls short
The pricing page publishes no figures, only the shape of the two plans, so a budget comparison needs a quote call. Single-project access ends at a fixed time, which matters if a process overruns.
Wrong for
Buyers who want a published price before talking to anyone, or teams whose main interest is AI-driven redaction and indexing, should compare SecureDocs or Ansarada first.

#2 Ansarada
Deal-preparation room with AI sorting and redaction · Australia · ansarada.com
M&A AI redaction Prepare free
Ansarada separates preparation from execution. A room is free to create and fill until it goes live, which its terms define as inviting guests or making the project visible to outsiders, or until 90 days pass.
- Pricing: Usage-based. Online quote builder; the room is free to set up and prepare, and payment starts when it goes live or after 90 days. Free plan: free trial.
- Best for: Sellers preparing a first sale
- Strengths: Smart Upload sorting; AI-Redact; Data gauge.
Where it falls short
Plans can only be upgraded or downgraded at the end of the contracted term, and extra data is billed at the peak of the billing period, so clearing files afterwards does not cancel an overage.
Wrong for
Companies that want a month-by-month plan they can resize mid-contract, or buyers who need a published list price before opening any form, will find the terms stiff.

#3 iDeals
General-purpose room with stated entry price · Switzerland · idealsvdr.com
Fundraising SOC 2 / ISO 27001 AI
iDeals publishes more than most rivals: a seven-day trial with unlimited use, SOC 1/2, ISO 27001 and GDPR compliance on the sign-up page, and a stated starting figure for its Pro plan of $2,700 per year.
- Pricing: Per project or annual. Pro plans start at $2,700 per year; Business and larger scopes are quoted on project requirements. Free plan: free trial.
- Best for: Cross-border deals and fundraising
- Strengths: Q&A; Electronic signature; External file sharing.
Where it falls short
Only the Pro entry price is stated; the Business plan and the larger scopes need a quote. The sign-up flow also leans on callbacks and a regional manager, which is slower than a self-service checkout.
Wrong for
A buyer who needs a monthly plan with no commitment, or one who wants a fully published price grid across all tiers, should look at SecureDocs or CapLinked.

#4 Datasite
M&A platform with data room, intelligence and AI · United States · datasite.com
M&A Enterprise AI agents
Datasite describes itself as the infrastructure for M&A and says its customers ran 55,000 or more M&A deals a year, including four of the top five in 2025. The product covers a sell-side room, a buy-side room, deal staging, archive, board management and a market-intelligence module, with AI agents and a connector for AI assistants.
- Pricing: Quote only. No prices on the pages we could read; buyers are sent to a demo. Free plan: none.
- Best for: Large sell-side and buy-side deals
- Strengths: Sell-side data room; Buy-side data room; Deal archive.
Where it falls short
Pricing is hidden behind a demo request, and the product has grown into intelligence, board and pipeline tools that a company selling one subsidiary will never open.
Wrong for
Start-ups, small advisers and anyone with a single modest transaction should not begin here, since the platform is built around volume.

#5 Intralinks VDRPro
Enterprise data room from SS&C · United States · intralinks.com
Enterprise IRM Redaction
VDRPro is SS&C Intralinks' room for transactions. Its page highlights information rights management that lets a user revoke access to a file even after download, AI-powered redaction of personal data, bulk Q&A import with priority and access controls, a mobile app, and support around the clock in over 140 languages.
- Pricing: Quote only. Quote only; the product page offers a get-a-quote form and lists no figures. Free plan: none.
- Best for: Banks and large corporate sellers
- Strengths: Information rights management; AI redaction of PII; Q&A bulk import.
Where it falls short
No price is shown and the page does not describe a self-service start, so a small seller will probably need a sales conversation.
Wrong for
Teams selling a small business on a four-week timeline, or founders who want to open a room tonight, should not start with an enterprise sales process that ends in a long contract.

#6 Drooms
German data room with European hosting · Germany · drooms.com
Germany EU hosting Real estate
Drooms is a Frankfurt company that says it runs on georedundant servers in Europe with 99.9% uptime, and it lists ISO 27001, ISO 27018, GDPR compliance and a TÜV certificate. The product is split into Drooms Hub and Drooms Intelligence. Hub handles the room, with Q&A and approval flows, and a certified archive.
- Pricing: Quote only. No prices on the pages we read; a pricing page and a start-for-free option exist. Free plan: free trial.
- Best for: European real estate and M&A deals
- Strengths: Redaction; Auto naming; Auto allocation.
Where it falls short
The public pages show no prices, and the English site returns less detail on plans than the leading rivals.
Wrong for
A seller who needs published prices up front, or one outside Europe with no hosting requirement and no use for German-language support, may be better served by SecureDocs or Firmex.
Visit Drooms →
#7 Imprima
AI-assisted data room from Amsterdam · Netherlands · imprima.com
AI due diligence Europe White label
Imprima's site is organised around AI modules for due diligence: Q&A that proposes answers and points to supporting paragraphs, summaries of legal documents, review of clauses, indexing, multilingual redaction and translation. The room also offers an API, a SharePoint link, single sign-on and a white-label option for resellers.
- Pricing: Quote only. No prices on the pages we read; contact sales for a quote. Free plan: none.
- Best for: Legal and real estate due diligence
- Strengths: Smart Q&A; Smart Summaries; Smart Review.
Where it falls short
No pricing is published, and the AI modules matter only if your deal has enough documents and languages to repay them.
Wrong for
A company with a small, English-only document set, or a buyer who wants to compare prices without a sales call, should look at SecureDocs or CapLinked.
Visit Imprima →
#8 SecureDocs
Flat-fee data room with unlimited users · United States · securedocs.com
Flat fee SOC 2 Small deals
SecureDocs states its prices: $250 a month billed annually, or $400 a month on a three-month plan billed quarterly, both with unlimited users, unlimited documents and 24/7 support. It states a successful SOC 2 Type 2 audit and hosts on AWS data centers.
- Pricing: Flat monthly. Flat fee from $250 per month on a 12-month plan, $400 per month on a 3-month plan; unlimited users and documents. Free plan: free trial.
- Best for: Small deals on a fixed budget
- Strengths: Unlimited users; Unlimited documents; Permission-based roles.
Where it falls short
The public pages do not describe AI redaction, bidder analytics or an archive product, and the vendor is part of Onit, Inc., a wider legal software company, so the data room is one product among several.
Wrong for
Auctions with many bidder teams and heavy redaction needs, or buyers who need a stated EU hosting guarantee for personal data, should compare Ansarada or Drooms before committing.
Visit SecureDocs →
#9 CapLinked
Mid-priced room with rights management · United States · caplinked.com
Fundraising DRM SOC 2
CapLinked prices two plans in public: a $399-a-month tier with a 14-day free trial and no long-term contract, and an Enterprise tier from $500 a month or $5,000 a year.
- Pricing: Flat monthly. A $399 per month plan with a 14-day free trial; Enterprise starts at $500 per month or $5,000 per year. Free plan: free trial.
- Best for: Fundraising and small M&A
- Strengths: Dynamic watermarks; FileProtect DRM; Q&A.
Where it falls short
The pages we read do not describe AI redaction or a data-volume tier, and the starting plan caps what a larger auction needs.
Wrong for
Teams that need AI redaction at scale, a data-volume plan with an archive product, or EU-only hosting guarantees should look at iDeals, Drooms or Imprima instead.

#10 Onehub
Workspace file sharing with a data-room tier · United States · onehub.com
Workspaces Per user Data room tier
Onehub sells workspaces, not auction rooms. Its Standard and Advanced plans are per-user file sharing at $15 and $25 a month, and the Premium edition adds the data-room features: document watermarks, automatic indexing, non-disclosure agreements, stealth mode that hides users from each other, dedicated support staff and customized training. Premium is priced at $375 a month, or $300 a month billed annually.
- Pricing: Per user / month. Standard $15 and Advanced $25 per user per month; Premium data-room edition $375 per month, $300 billed annually. Free plan: free trial.
- Best for: Firms that share files and run deals
- Strengths: Workspaces; Custom domain and white label; Two-factor enforcement.
Where it falls short
The product is a file-sharing tool first, so it lacks the transaction process of the specialist rooms: bidder analytics, structured sell-side preparation or AI sorting are not described on the pages we read.
Wrong for
A banker running a competitive auction, or a seller expecting dozens of bidder teams and a formal Q&A process, should use a specialist room instead of a workspace tool.

#11 Egnyte
Content governance platform with external sharing · United States · egnyte.com
Governance Per user Financial services
Egnyte's pricing page lists four tiers at $22, $39 and $48 per user a month, billed annually, plus an Ultimate tier on quote. Dynamic watermarking and e-signature arrive at the Elite tier. The company's industry pages list buy-side and sell-side use cases within financial services and controlled external file sharing as a use case.
- Pricing: Per user / month. Business $22 per user per month, Enterprise Lite $39, Elite $48, all billed annually; Ultimate on quote. Free plan: free trial.
- Best for: Existing Egnyte firms with occasional deals
- Strengths: Dynamic watermarking; E-signature; PDF markup.
Where it falls short
We found no dedicated data-room product page or process tools such as bidder Q&A on the pages we read, so a deal team must assemble the workflow from sharing features and folder permissions.
Wrong for
A seller who needs a ready-made auction process with a Q&A workflow and bidder reports should pick a specialist room, and a firm without existing Egnyte contracts has no reason to start here.
Visit Egnyte →
#12 ShareFile
Client portal and file sharing with a data-room offering · United States · sharefile.com
Client portal E-signature Progress
ShareFile belongs to the Progress Software portfolio and is sold mainly to accounting, finance, insurance, healthcare, legal and real estate firms that swap documents with clients. Its pricing page shows Advanced at $18.15 and Premium at $28.59 per user per month, with a three-user minimum and lower rates on annual billing.
- Pricing: Per user / month. Advanced $18.15 and Premium $28.59 per user per month (lower when billed annually); minimum three users; the data-room plan is not priced. Free plan: free trial.
- Best for: Accounting and finance firms
- Strengths: Client portal; Integrated e-signature; Workflow automation.
Where it falls short
The dedicated data-room page returned an error when we fetched it, and the data-room plan carries no public price, so we cannot describe its features or limits.
Wrong for
A company seeking a specialist deal room for its first sale should compare Firmex or Ansarada rather than a client-portal product, and a firm with no recurring client exchange gains little.

#13 Box
Content cloud with governance add-ons · United States · box.com
Content cloud Governance Free plan
Box offers a permanent free Individual plan with 10 GB of storage, and paid plans per user per month from Business Starter upward, with a three-user minimum. Governance with retention policies and legal holds is an add-on, Box Shield adds classification-based controls, and Enterprise Advanced includes an archive product.
- Pricing: Per user / month. Free Individual plan; Business Starter from $5 per user per month; higher plans per user; Enterprise Advanced on quote. Free plan: free plan.
- Best for: Firms already standardised on Box
- Strengths: 10 GB free plan; Box Sign; Version history.
Where it falls short
Retention, Shield and compliance archive are separate add-ons without listed prices, and the pricing page does not show data-room features such as bidder Q&A or per-bidder reports.
Wrong for
A team needing an auction process with Q&A and bidder reports should use a specialist room.

Questions and answers
What is the best virtual data room software in 2026?
Firmex ranks first of 13, best for mid-size deals and repeat dealmakers. Ansarada is second (sellers preparing a first sale) and iDeals third (cross-border deals and fundraising). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
How much does a virtual data room cost?
It depends on the billing shape. SecureDocs publishes a flat $250 a month on a 12-month plan and $400 on a 3-month plan, and CapLinked lists $399 a month. iDeals states Pro plans from $2,700 a year.
Can I use Dropbox, Google Drive or Box instead of a data room?
For a small, friendly exchange, yes. For a competitive process, usually no. General platforms lack the structured Q&A between buyer and seller, the per-bidder activity report and the preparation workflow that a data room provides.
Is there a free virtual data room?
Not for a real transaction. Box has a free Individual plan with 10 GB, but it is a personal storage plan, not a deal room.
What happens to the room after the deal closes?
Plan this before you sign. Counsel may need the folder structure and access logs for years.
How should I price a data room for a three-month sale?
Build one scenario and send it to every vendor: number of documents and total size, number of bidder teams and users per team, planned length, and what happens if the deal slips by a month.
Do buyers need accounts, and do they pay?
Buyers are invited as guest users and do not pay in the specialist rooms; the seller carries the cost. Ansarada separates internal sell-side users from external buy-side users when teams are set up.
Where is my data stored, and does that matter for GDPR?
It matters when personal data of EU residents sits in the room, which is usual for employee and customer files in a sale. Drooms states georedundant servers in Europe and lists ISO 27001, ISO 27018 and GDPR compliance.
Is AI redaction worth paying for in a data room?
If the room holds hundreds of contracts and personnel files, yes, because manual redaction before a sale is slow and error-prone. Ansarada, Imprima, iDeals, Drooms and Intralinks describe AI redaction or similar tooling on their sites.
Can a start-up use a data room for fundraising?
Yes, and a cheaper product usually does the job. Investors need a clean folder structure, view tracking and a way to ask questions, not an auction process.
When should I choose Datasite or Intralinks?
When the deal is large enough that bankers, not you, define the process, or when the buyer or lender names the platform.
