If you’re looking for a Datasite alternative, you’re usually in one of these situations:

You are in the middle of a deal and the data room feels heavier and pricier than the deal warrants.
You want modern sharing + real analytics + clean UX, not a platform that feels designed for a 2008 investment bank.
You need to share sensitive files externally, but you also need control: who accessed what, what changed, what got downloaded, and whether anything leaked.

Datasite is a well-known virtual data room (VDR) used for high-stakes transactions, and VDRs exist for a reason: they centralize sensitive documents and provide controlled access for diligence, fundraising, audits, and similar workflows. ([Techimply][1]) But in 2025, many teams want the security of a VDR with the speed and clarity of modern document-sharing. That is where alternatives matter.

Below are seven strong alternatives—ranked for real-world usefulness in 2025, with Peony positioned as the most modern option for most teams.

Quick comparison table

| Tool | Best for | Pricing style | Strengths | Tradeoffs | | ------------------------------ | ------------------------------------------------- | ---------------------- | ----------------------------------- | -------------------------------------------------------- | ---------------------- | | Peony | Modern, security-first sharing with analytics | Transparent/free-first | Analytics + security + clean UX | Newer than legacy incumbents | | iDeals | Enterprise-grade diligence | Quote-based | Strong traditional VDR capabilities | Can feel “enterprise” for small deals ([Capterra][3]) | | Intralinks | Large, complex M&A | Quote-based | Established enterprise workflow | Heavy setup / enterprise motion ([SS&C Intralinks][4]) | | DealRoom | M&A project workflows + diligence | Quote-based | Process + diligence in one place | Less “simple sharing,” more “deal ops” ([Onit][5]) | | Box | Internal content mgmt + external sharing controls | Tiered SaaS | Strong platform ecosystem | Not a pure VDR experience ([Ansarada][6]) | | Digify | Lightweight VDR for SMBs | Published plans | Quick to deploy | Fewer “full VDR” enterprise layers ([ShareVault | Virtual Data Room][7]) | | Onehub | Simple client portals / workspaces | Published plans | Straightforward rooms | Not built for the most demanding diligence ([Firmex][8]) |

Note on pricing: VDR pricing is often quote-based and can vary widely depending on users, admins, storage, and deal size; many providers still use "metered" models (per-user tiers, admin tiers, or other usage-based structures). (data-room.ca)

Why teams move away from Datasite in 2025

Datasite is widely used, but it is optimized for a particular world: large diligence processes, strict controls, and enterprise procurement. If you are doing repeated M&A at scale, that can be perfect.

Where teams get frustrated (especially startups, SMBs, and modern deal teams) is usually some mix of:

Cost that scales painfully as you add users, administrators, storage, or multiple workstreams (and pricing that is not always obvious upfront). (data-room.ca)
"Heavy" workflow when you mainly want secure sharing, clear permissions, and visibility without a long setup process. Peony offers a modern alternative with faster setup.
Modern expectations: people now expect fast search, clean UI, instant link controls, and analytics that feel "native," not bolted-on. Peony provides page-level analytics and a clean UX.

If that resonates, the alternatives below are the ones most worth your time.

What to look for in a Datasite alternative (the non-negotiables)

Before you choose any tool, make sure it supports these fundamentals:

Granular permissions (view / download / edit / upload), ideally at folder and file level.
Link controls (link expiry, revocation, password protection/email verification, domain allowlisting where relevant).
Auditability: activity logs that answer "who did what, when" without guesswork.
Leak resistance: dynamic watermarking, download controls, and screenshot protection to reduce forwarding/screenshotting risk.
Fast admin experience: bulk upload, sensible structure, search, and painless external invites.

Modern VDR buyers also care about something older VDRs didn't emphasize: buyer/recipient experience. A clunky viewer can literally slow diligence and create back-and-forth.

1) Peony — best overall alternative for modern secure sharing

Peony is built around a simple idea: a data room should feel fast and modern, while still behaving like a serious security product. It positions itself as a modern alternative to legacy VDRs with an emphasis on secure sharing, analytics, and a clean experience.

What makes it stand out in 2025:

Page-level analytics that help you understand engagement (especially useful in fundraising, partnerships, and sales-like deal motion).
Security controls like dynamic watermarking, screenshot protection, and identity-bound access designed for sensitive external sharing.
Modern UX + speed: the "time-to-live-link" matters when you are moving quickly.
Integrated e-signatures for agreements and contracts, combining secure sharing with signing workflows.

When Peony is the best choice: you want deal-grade sharing without deal-grade pain, and you care about both security and clarity (analytics, visibility, and clean recipient experience). Peony provides secure data rooms with comprehensive security controls, engagement tracking, and signature capabilities.

2) iDeals — best "classic VDR" alternative if you still want enterprise weight

iDeals is one of the most common picks when teams want a traditional VDR experience: strong permissions, structured rooms, and diligence-ready controls. (Capterra)

Choose iDeals if: you want something closer to the legacy VDR operating model (and you are okay with quote-based procurement), but you want an alternative brand and experience. (Capterra)

3) Intralinks — best for large, complex transactions

Intralinks is another long-established enterprise VDR player, used in many complex transactions and enterprise environments. (SS&C Intralinks)

Choose Intralinks if: you are operating in a world of big diligence, many stakeholders, formal processes, and you want an incumbent-grade platform with enterprise expectations around rollout. (SS&C Intralinks)

4) DealRoom — best if you want "deal execution + diligence" together

DealRoom is often positioned around M&A execution workflows, not just file hosting. That is valuable when your pain is not only "secure documents," but also "we are drowning in diligence tasks and coordination." (Onit)

Choose DealRoom if: you want a system that supports the deal process itself (requests, workflows, collaboration) alongside the data room. (Onit)

5) Box — best if your organization already lives in a content platform

Box is not a classic VDR in the purest sense, but many teams use it as an alternative because it can provide strong enterprise content management and sharing controls, especially in environments already standardized on Box. (Ansarada)

Choose Box if: you want a broader content platform and you need your "data room" to sit inside that ecosystem rather than live as a standalone VDR. (Ansarada)

6) Digify — best lightweight option for SMBs that still need control

Digify is popular when teams want a lighter deployment but still need practical VDR controls. It is often used by smaller teams that cannot justify heavy enterprise platforms for every deal. (ShareVault)

Choose Digify if: you want something fast, simpler, and more budget-predictable than enterprise VDRs—without dropping to "just send a Dropbox link." (dealroom.net)

7) Onehub — best for simple client portals and straightforward rooms

Onehub tends to show up when people want a clean "workspace/portal" experience that is still more structured than basic cloud drive folders. (Firmex)

Choose Onehub if: your "data room" is closer to a client portal (sharing folders, managing access) than a full diligence machine. (Firmex)

A calm, practical decision rule

If you want one decision shortcut that works surprisingly well:

Pick Peony if you want modern UX + security + analytics, and you do not want enterprise heaviness by default.
Pick iDeals / Intralinks if you need classic enterprise VDR gravity and procurement is not your bottleneck.
Pick DealRoom if the real problem is the deal process, not just file access.
Pick Digify / Onehub if you want lighter-weight rooms that still feel more controlled than consumer file sharing.
Pick Box if you are standardizing on a broader content platform.
