Datasite vs Intralinks: A Detailed Virtual Data Room Comparison

If you’re shortlisting virtual data rooms for an upcoming deal, Datasite and Intralinks have probably both come up. Both are established names in the space, both are used across major M&A transactions, and both claim enterprise-grade security. So what actually separates them when you’re the one managing documents under deadline pressure?

A virtual data room is a secure online repository for storing and sharing sensitive documents during high-stakes transactions — M&A, capital raising, restructuring, and regulatory audits, among others. If you need the fuller picture of how VDRs work in general, see our complete guide to virtual data rooms. This article assumes you already know that much and want to know specifically how Datasite and Intralinks differ.

Three things actually decide this comparison: security posture, day-to-day usability, and how each vendor handles pricing. We’ve added a fourth angle at the end for teams running cross-border deals through Hong Kong.

What is Datasite?

• Formerly known as Merrill DataSite, part of Merrill Corporation, before rebranding to Datasite in 2020. The parent entity’s roots trace back to 1968, when Merrill Corporation was founded in Minneapolis, Minnesota, as a financial printing and document services business.
• Product suite spans the deal lifecycle: Datasite Diligence (the core data room), Datasite Acquire, Datasite Pipeline, and Datasite Archive — rather than a single one-size-fits-all product.
• Support is delivered through Datasite Assist, available 24/7/365, with support commonly cited as covering around 20 languages (confirm the current figure directly with Datasite before publishing, as sources vary).
• Known for AI-powered redaction that automatically identifies and masks sensitive information, along with deal analytics and reporting built around the M&A process specifically.

What is Intralinks?

• Founded in 1996 in New York, and widely credited as one of the pioneers of the virtual data room category.
• Acquired by SS&C Technologies in September 2018, and now operates under the SS&C Intralinks brand.
• Known for deep experience in cross-border and global banking transactions, with a long track record navigating multiple regulatory regimes at once.
• Some independent user reviews describe the interface as more complex and the onboarding process as slower compared to newer competitors — worth factoring in if your team values a short learning curve over deep configurability.

Datasite vs Intralinks: feature-by-feature comparison

Security and certifications

Both platforms are built for enterprise-grade due diligence and go well beyond what generic cloud storage offers — encryption in transit and at rest, granular permissions, dynamic watermarking, and full audit trails are table stakes for both. Administrators on either platform can restrict access down to individual folders or files, set view-only permissions that block downloads and printing, and pull a full activity log showing who viewed, downloaded, or attempted to access which documents and when — the kind of record that matters if a deal is ever challenged or a regulator asks questions after closing.

Where you’ll see a claimed difference is certification scope: Intralinks’ own comparison materials cite ISO 27701 (the international standard for privacy information management) as a point of distinction, stating that Datasite has not achieved it. Treat this carefully — it’s a claim made on a competitor’s own marketing page, not an independently verified fact. If ISO 27701 specifically matters for your deal (for example, because of a data-privacy-heavy regulatory footprint), confirm current certification status directly with each vendor’s trust or security page rather than relying on either company’s comparison materials.

Usability and onboarding

Independent reviews on platforms like G2 and Capterra consistently describe Datasite’s interface as easier to pick up quickly, which matters when you’re onboarding external counsel, auditors, or bidders who won’t get formal training on the platform. Several reviewers note that Intralinks, while powerful, has a steeper learning curve and a setup process some users describe as more involved.

Neither of these observations should be taken as absolute — team familiarity, deal complexity, and prior experience with either platform all affect how a specific group experiences onboarding. But if your deal team is smaller or your external parties are less tech-savvy, factor this in.

Pricing model

Here’s the practical reality: neither Datasite nor Intralinks publishes pricing publicly. Both operate on a quote-based model, typically scoped by page count or data volume and the length of the engagement — you’ll need a sales conversation with either vendor to get an actual number for your deal. In practice, this means the same deal can price very differently depending on document volume, how many bidders need access, and how long the room needs to stay open, so a quote obtained for one transaction won’t reliably predict the cost of the next.

One aggregator listing shows a headline figure of roughly $25/month for an ‘Intralinks VDRPro’ entry, but this looks like a mislabeled or entry-tier SKU rather than a representative enterprise price — treat it with skepticism and get a direct quote instead of anchoring on a number found on a third-party listing site.

This is worth knowing upfront so you’re not left searching for a number that doesn’t exist publicly. If a transparent, published price list matters more to your team than the specific feature set of either platform, it’s worth comparing both against Ansarada, which does publish its pricing online — see our full Ansarada vs Datasite comparison and Ansarada provider review for that angle. For a broader view of what data rooms cost across the market, our data room pricing guide breaks down the different pricing models in use.

Document management and AI features

This is where the two platforms diverge most in practice, not just on paper.

Datasite’s AI redaction automatically identifies and masks personally identifiable information — tax IDs, account numbers, contact details — across large document sets. For a due diligence process involving thousands of files, this can meaningfully cut down the hours a deal team spends manually reviewing and redacting sensitive content before granting buyer access. Datasite pairs this with automated indexing and categorization, so a data room can be structured quickly even when documents arrive from multiple sources in inconsistent formats.

Intralinks leans more on its DealCentre platform for managing the broader transaction lifecycle — tracking deal stages, coordinating advisors, and centralizing communication alongside document access. Its strength here is less about document-level AI processing and more about giving deal leads a single operational view across a complex, multi-party transaction.

Neither approach is objectively better — it depends on whether your bottleneck is document preparation (where Datasite’s redaction tooling helps most) or transaction coordination across many stakeholders (where Intralinks’ deal-management layer is the stronger fit).

Q&A and collaboration workflow

Both platforms include a structured Q&A module for managing buyer questions during due diligence — questions get routed to the right internal owner, answers are logged, and the whole exchange becomes part of the audit trail rather than living in scattered email threads.

The practical difference reviewers point to is speed of setup versus depth of routing logic. Datasite’s Q&A workflow is generally described as faster to configure for a single, well-defined deal. Intralinks’ Q&A and broader collaboration tools are built with larger, more complex deal teams in mind — multiple advisory firms, several workstreams running in parallel — where more granular routing and role assignment pays off, at the cost of a longer initial setup.

Typical use cases

• Datasite is commonly used for: sell-side and buy-side M&A due diligence, IPO preparation, and restructuring processes where a structured, repeatable workflow and fast redaction matter.
• Intralinks is commonly used for: large-scale global banking transactions, capital markets deals, and cross-border processes involving multiple regulatory regimes and a longer transaction timeline.
• Both are used for: general M&A due diligence, investor reporting, and secure document exchange with external counsel — the overlap is real, and for a mid-sized, single-jurisdiction deal, either platform will likely cover the basics.

Datasite vs Intralinks for Hong Kong and cross-border deals

For teams running deals that span Hong Kong, mainland China, and international capital markets, the calculus shifts slightly. Intralinks’ decades of experience in global banking and its track record navigating multiple regulatory regimes at once make it a natural fit for Hong Kong’s position as a gateway between international and mainland Chinese capital markets — the kind of deal where jurisdictional complexity is the main risk to manage.

Datasite, meanwhile, is a strong fit for HKEX-adjacent M&A and IPO due diligence specifically, where its structured, process-first workflow and deal-stage reporting matter as much as jurisdictional reach.

One caveat that applies to both: neither vendor publishes Hong Kong-specific data residency terms on its public marketing pages. If your organization operates under SFC supervision, confirm data location and access-control specifics directly with either provider — as covered in our guide to virtual data rooms in Hong Kong and Asia-Pacific — before adding either platform to a shortlist.

For a cross-border deal touching mainland China specifically, ask both vendors directly how their platform handles data transfer restrictions and whether any region-specific hosting options exist for your deal — this detail changes deal to deal and isn’t something either company’s general marketing page will answer definitively.

Which should you choose?

• Choose Datasite if: your deal is M&A-process-driven, redaction volume is high, and your team values a structured workflow with strong reporting over raw jurisdictional reach.
• Choose Intralinks if: the deal spans multiple regulatory regimes, involves global banking counterparties, or benefits from a longer enterprise track record in cross-border work.

If neither quite fits — say you want AI-driven deal readiness scoring, or a published price list instead of a sales call — it’s worth reading how Ansarada compares to Datasite, or checking Ideals vs Datasite if ease of use and predictable permissions matter more to you than enterprise scale. And if your deal team is running its first transaction and just wants a straightforward due diligence process without deep-diving into every vendor’s feature list, either Datasite or Intralinks will cover the fundamentals — the choice between them comes down to workflow style, not a meaningful security gap.

Final thoughts

Both Datasite and Intralinks are capable, enterprise-grade virtual data rooms, and neither publishes pricing — so a budget conversation happens either way, regardless of which you choose. The real decision point isn’t a feature checklist; it’s whether your deal is better served by Datasite’s process-driven workflow or Intralinks’ cross-border regulatory depth. Match that to your actual transaction, not to whichever vendor’s sales page you read first.

Whichever you choose, ask for references from a deal of similar size and complexity to yours, and get the quote in writing before your data room needs to go live — pricing conversations for either platform can take longer than expected, and you don’t want that timeline colliding with a signing deadline.

Frequently Asked Questions

Is Datasite or Intralinks cheaper? Neither company publishes pricing, so there’s no public list price to compare. Both use a quote-based model typically scoped by page count or data volume, meaning the actual cost depends on your specific deal size and duration — request a quote from each to compare directly.

Which is better for a first-time M&A deal? Datasite’s more structured, process-driven workflow and generally faster onboarding tend to suit teams running their first or an occasional M&A process. Intralinks’ depth is more valuable once your team is already managing complex, multi-jurisdictional transactions regularly.

Does either platform publish Hong Kong-specific data residency terms? Not on their public marketing pages. If your organization is subject to SFC supervision or similar regulatory oversight, confirm data location and access-control specifics directly with the vendor before shortlisting.

Is Intralinks really ISO 27701 certified and Datasite isn’t? This claim appears on Intralinks’ own comparison materials. It hasn’t been independently verified here — confirm current certification status directly with each vendor’s trust or security page before relying on it.

Are there alternatives worth considering alongside these two? Yes — Ansarada publishes its pricing publicly (unlike either platform here), and Ideals is often cited for its simpler permissions model. See our Ansarada vs Datasite and Ideals vs Datasite comparisons for a fuller picture.
