I Tested 10 OneDrive Alternatives — Here's What Actually Works (2026)

I've used OneDrive for years as part of Microsoft 365 — first at a corporate job, then while building Peony. It works well enough for internal file storage, but the moment I needed to share a pitch deck with investors or send due diligence materials to an acquirer, the limitations hit hard: no engagement analytics, generic sharing links, clunky external permissions, and zero insight into whether anyone actually read the documents I sent.

With Microsoft retiring standalone OneDrive plans in May 2026, pushing everyone toward $6.99+/month Microsoft 365 bundles, now is the right time to evaluate what else is out there. I spent the past several months testing 10 alternatives across real workflows — startup fundraising, client file sharing, team collaboration, and M&A due diligence — to see which ones actually deliver. When it comes to professional external sharing, Peony (free, $0) is the AI-native data room I built with page-level analytics, watermarks, screenshot protection, and e-signatures purpose-built for secure document sharing.

TL;DR: OneDrive is solid for Microsoft 365 users who only need internal storage, but it falls short on external sharing, analytics, and security. The best alternative depends on your use case: Peony (free, $0) for professional external sharing with investors and clients, Google Drive ($0–12/user/mo) for Google Workspace teams, Dropbox ($11.99/mo) for cross-platform sync, Tresorit ($14.50/user/mo) or Sync.com ($8/user/mo) for zero-knowledge encryption, and iDeals (custom) for enterprise M&A. I signed up for every platform on this list, uploaded real documents, tested sharing workflows, and compared the actual experience. Here's my honest ranking.

OneDrive Alternatives at a Glance

Bottom line: No single tool replaces OneDrive for every use case. Google Drive is the closest general-purpose swap for Google Workspace users. For sharing documents externally with analytics and security, Peony is the clear leader at $0. For maximum encryption, Tresorit and Sync.com stand out.

By the Numbers

• $96.4 billion — global cloud storage market in 2025, projected to reach $266.4 billion by 2030 (MarketsandMarkets)
• 345 million paid subscribers across Microsoft 365 as of Q3 FY25, bundling OneDrive with the full Office suite (Microsoft)
• 3+ billion files created or uploaded to Google Drive every day, making it the most-used cloud storage platform globally (Google Workspace blog)
• 700 million registered Dropbox users worldwide, though only 18.2 million are paying subscribers (Dropbox SEC filings)
• 15 GB free storage on Google Drive vs. 5 GB free on OneDrive — a 3x difference in the free tier
• May 2026 — Microsoft's deadline for retiring standalone OneDrive 100 GB plans, pushing users to $6.99+/month Microsoft 365 bundles (Microsoft 365 blog)
• 4.7/5 — iDeals' G2 rating from 900+ reviews, the highest-rated virtual data room on G2

1. Peony — Best for Professional External Sharing

Peony is a free, AI-powered data room built for sharing documents securely with people outside your organization — investors, clients, acquirers, and partners.

What it is: An AI-native data room and document sharing platform purpose-built for professional external workflows: fundraising, due diligence, client collaboration, and board reporting. Full disclosure: I'm the founder, so I'll focus on specific features and let you compare.

Key strengths:

• Free forever — unlimited data rooms, no paywall for core features, no per-page pricing
• Page-level analytics show exactly which pages each viewer spent time on and for how long
• Dynamic watermarks and screenshot protection deter unauthorized redistribution
• AI-powered organization automatically structures uploaded documents into logical folder hierarchies
• Built-in e-signatures, NDA gating, link expiry, password protection, and revocable access

Limitations:

• Not a general-purpose cloud storage replacement — designed for external sharing, not internal team file storage
• Newer platform with a smaller user base than established incumbents
• No desktop sync client (file sync is not the product's focus)
• No native Microsoft Office co-editing integration

Pricing: Free ($0) — peony.ink

Best for: Founders sharing pitch decks with investors, startups running due diligence, agencies sending client deliverables, and anyone who needs to know whether recipients actually read their documents.

vs. OneDrive: OneDrive stores files; Peony shares them intelligently. If your problem is "I need to send a confidential document and know exactly who viewed it, for how long, and which pages," OneDrive does not do that. Peony does.

When I built Peony, the trigger was sending a 40-page investor deck via OneDrive and having zero idea whether any of the 12 investors I sent it to even opened it. Page-level analytics changed how I ran my fundraise — I could follow up specifically with investors who spent 5+ minutes on the financial model section.

---

2. Google Drive — Best for Google Workspace Teams

Google Drive is the most-used cloud storage platform globally, with 15 GB of free storage and deep integration across Gmail, Docs, Sheets, and Slides.

What it is: Google's cloud storage and collaboration platform, bundled with Google Workspace. Over 3 billion files are created on it daily.

Key strengths:

• 15 GB free storage — 3x more than OneDrive's free tier
• Real-time co-editing in Google Docs, Sheets, and Slides with no file format conversion needed
• Deep search powered by Google's search infrastructure (including text-in-image OCR)
• Available on every platform: web, iOS, Android, Windows, macOS
• Google Workspace Marketplace with thousands of third-party integrations

Limitations:

• File format lock-in: Google Docs/Sheets/Slides are native formats that require conversion for non-Google users
• External sharing produces generic drive.google.com links with no engagement tracking
• Granular permissions management becomes chaotic at scale (who has access to what?)
• No watermarking, no NDA gating, no screenshot protection for shared files

Pricing: Free (15 GB) / Business Starter $7/user/mo / Business Standard $14/user/mo / Business Plus $22/user/mo (Google Workspace pricing)

Best for: Teams already in the Google ecosystem who need collaborative editing and basic file sharing internally.

vs. OneDrive: The Google Drive vs OneDrive choice usually comes down to ecosystem: Google Workspace users should choose Google Drive, Microsoft 365 users should stick with OneDrive. Feature-for-feature, they're comparable for internal use. Neither excels at external sharing.

What surprised me about Google Drive is how quickly permissions spiral out of control. After six months of a startup using it, we had hundreds of files shared with "anyone with the link" and no way to audit who actually had access. There is no equivalent of a centralized link management dashboard.

---

3. Dropbox — Best for Cross-Platform Sync

Dropbox pioneered consumer cloud sync and still offers the most reliable cross-platform file synchronization experience, with 700 million registered users.

What it is: File hosting and synchronization platform known for rock-solid syncing, Smart Sync (files on-demand), and a clean desktop experience across Windows, macOS, and Linux.

Key strengths:

• Smart Sync lets you see all files in your file system without downloading them — genuinely the best implementation of files-on-demand
• Reliable sync across Windows, macOS, Linux, iOS, and Android with minimal conflicts
• Dropbox Paper for lightweight collaborative documents
• Transfer feature for sending large files (up to 100 GB on Professional plan) with download tracking
• Dropbox Sign (formerly HelloSign) integration for e-signatures

Limitations:

• Only 2 GB free storage — the smallest free tier on this list
• Plus plan ($11.99/mo) is single-user only; team plans start at $15/user/mo
• History of privacy and security controversies over the years
• Limited external sharing analytics — you can see if someone downloaded a file, but not which pages they read

Pricing: Basic Free (2 GB) / Plus $11.99/mo / Essentials $22/mo / Business $15/user/mo / Business Plus $24/user/mo (Dropbox plans)

Best for: Individuals and small teams who need reliable file sync across multiple devices and operating systems, especially if they use Linux.

vs. OneDrive: Dropbox syncs more reliably across non-Windows platforms. OneDrive integrates deeper with Office apps. For pure sync quality, Dropbox still wins — but the 2 GB free tier vs. OneDrive's 5 GB is a real disadvantage for free users.

In my experience with Dropbox, the sync engine is still best-in-class. Files appear on my second machine within seconds. Where it falls short is the same place OneDrive does: sharing a folder with an investor and knowing what happened next. Did they open it? Did they read past slide 3? Silence.

---

4. Box — Best for Enterprise Compliance

Box is the enterprise content management platform of choice for regulated industries, with FedRAMP authorization and 1,500+ integrations.

What it is: Cloud content management and file sharing platform built for enterprise governance, compliance, and workflow automation. Used by 68% of the Fortune 500.

Key strengths:

• FedRAMP authorized, HIPAA-compliant, GxP-validated — the compliance certifications list is extensive
• 1,500+ app integrations including Salesforce, Slack, Microsoft 365, and Google Workspace
• Box Shield for intelligent threat detection and DLP (data loss prevention)
• Granular admin controls: seven permission levels, retention policies, legal hold
• Box Relay for workflow automation without code

Limitations:

• Pricing is opaque — no self-serve plan for businesses; "contact sales" for most tiers
• Individual plans start at $16/user/mo (Business) and scale to $47/user/mo (Enterprise Plus)
• Enterprise features create complexity that small teams don't need
• G2 rating: 4.2/5 — slightly lower than competitors, with common complaints about performance

Pricing: Individual Free (10 GB) / Personal Pro $14/mo / Business $16/user/mo / Business Plus $27/user/mo / Enterprise $40/user/mo / Enterprise Plus $47/user/mo (Box pricing)

Best for: Enterprises in regulated industries (healthcare, finance, government) that need certifications and compliance built into their file sharing platform.

vs. OneDrive: Box is the better choice when compliance requirements go beyond what Microsoft Purview offers out of the box. OneDrive is more cost-effective when bundled with Microsoft 365. For most startups and small businesses, Box is overkill.

When I tested Box for a client engagement, the admin controls were impressive — I could set folder-level retention policies and watermarks on downloads. But setting up a simple external share required navigating five different permission screens. For enterprise IT teams that's fine; for a founder sending a deck to an investor, it is a poor experience compared to a purpose-built sharing tool like Peony.

5. pCloud — Best for Lifetime Pricing

pCloud is the only major cloud storage provider offering lifetime plans, with a one-time payment of $199 for 500 GB eliminating recurring subscription costs.

What it is: Switzerland-based cloud storage provider known for its lifetime pricing model and client-side encryption add-on (pCloud Encryption, sold separately).

Key strengths:

• Lifetime plans: $199 for 500 GB or $399 for 2 TB — pay once, use forever
• pCloud Drive creates a virtual drive on your computer without using local disk space
• Built-in media player for audio and video files directly from the cloud
• pCloud Encryption add-on provides zero-knowledge client-side encryption ($49.99 lifetime)
• Based in Switzerland with data stored in Luxembourg (EU) data centers — strong privacy jurisdiction

Limitations:

• Zero-knowledge encryption costs extra ($49.99 lifetime or $47.88/year) — it's not included by default
• Collaboration features are basic compared to Google Drive or Dropbox
• No native document editing — you need external apps to edit files
• G2 rating: 4.1/5 with a smaller review sample than major competitors

Pricing: Free (10 GB) / Premium 500 GB $199 lifetime or $49.99/year / Premium Plus 2 TB $399 lifetime or $99.99/year (pCloud pricing)

Best for: Cost-conscious individuals and freelancers who want to stop paying monthly cloud storage fees, especially those who primarily need storage and backup rather than collaboration.

vs. OneDrive: pCloud's lifetime plan ($199 for 500 GB) costs less than 2.5 years of OneDrive's $6.99/month standalone plan. If you don't need Microsoft Office integration, pCloud saves significant money over time.

What I appreciated about pCloud is the simplicity. Upload files, get a share link, done. But the share links are just as anonymous as OneDrive's — I couldn't tell if a recipient opened my file, spent 10 seconds on it, or read every page. For personal backups, pCloud is excellent. For professional sharing, you still need something like Peony's analytics layer.

6. Sync.com — Best for Zero-Knowledge Encryption

Sync.com provides end-to-end zero-knowledge encryption on all plans by default — no add-on required — making it one of the most privacy-focused cloud storage options available.

What it is: Canadian cloud storage provider that encrypts all files with zero-knowledge architecture, meaning Sync.com itself cannot access your data. HIPAA, PIPEDA, and GDPR compliant.

Key strengths:

• Zero-knowledge encryption included on all plans — not a paid add-on like pCloud
• HIPAA, PIPEDA, and GDPR compliant out of the box
• 5 GB free tier with full encryption (more generous than Dropbox's 2 GB)
• Data stored exclusively in Canadian data centers — strong privacy jurisdiction
• G2 rating: 4.4/5 with consistently positive privacy reviews

Limitations:

• Sync speed is noticeably slower than Dropbox or Google Drive — the encryption overhead is real
• No native document editing or real-time collaboration features
• Desktop app and web interface feel dated compared to competitors
• Smaller ecosystem: fewer third-party integrations than Box, Google Drive, or Dropbox

Pricing: Free (5 GB) / Teams Standard $8/user/mo / Teams Unlimited $15/user/mo / Enterprise: custom (Sync.com pricing)

Best for: Privacy-conscious professionals handling sensitive data — lawyers, accountants, healthcare providers — who need built-in zero-knowledge encryption without paying for a separate add-on.

vs. OneDrive: Sync.com encrypts files so that even the provider can't read them. OneDrive does not offer zero-knowledge encryption — Microsoft holds the encryption keys. If privacy is your primary requirement and you don't need Office integration, Sync.com wins on security architecture.

When I tested Sync.com for sharing encrypted files with a legal team, the security was solid, but the experience was bare-bones. No analytics on who opened what, no watermarks, no screenshot protection. The encryption protects files at rest, but once someone downloads a file, you lose all control. For documents that need both encryption and post-download protection, I would pair Sync.com with Peony's watermarking and screenshot protection.

---

7. Tresorit — Best for Security-First Teams

Tresorit combines zero-knowledge encryption with Swiss privacy law and enterprise admin controls, earning a 4.5/5 G2 rating and adoption by organizations like the German Federal Office for Information Security.

What it is: Swiss-headquartered, zero-knowledge encrypted cloud storage and file sharing platform acquired by Swiss Post in 2021. Built for organizations where data security is non-negotiable.

Key strengths:

• Zero-knowledge end-to-end encryption with keys that never leave your device
• Headquartered in Switzerland, subject to Swiss Federal Data Protection Act (one of the world's strongest privacy regimes)
• Admin controls: device wipe, session management, IP restrictions, and DRM-protected sharing
• Digital Rights Management (DRM) on shared links: disable downloads, set expiry, add watermarks
• G2 rating: 4.5/5 — highest-rated security-focused cloud storage

Limitations:

• $14.50/user/month (Business Standard) makes it one of the more expensive options
• Collaboration features are limited — no real-time co-editing like Google Docs
• Smaller ecosystem: fewer integrations than Box or Dropbox
• The security-first approach adds friction for less technical users

Pricing: Personal $11.99/mo / Business Standard $14.50/user/mo / Business Plus: custom (Tresorit pricing)

Best for: Legal firms, financial services, healthcare organizations, and any team where regulatory compliance and data security justify a premium price.

vs. OneDrive: Tresorit's zero-knowledge encryption is architecturally superior to OneDrive's server-side encryption. Tresorit also offers DRM on shared links (disable downloads, add watermarks) — features OneDrive lacks. The tradeoff is cost and convenience.

What impressed me about Tresorit is the DRM controls on shared files. I could share a PDF and disable the download button entirely — recipients could view it in-browser but not save a local copy. However, the page-level analytics are basic compared to what Peony offers. You know the link was opened, but not which pages held the reader's attention.

8. Zoho WorkDrive — Best for Zoho Ecosystem Users

Zoho WorkDrive offers team cloud storage starting at $2.50/user/month — by far the lowest per-user price for a business-grade platform — with tight integration across the 50+ apps in the Zoho suite.

What it is: Online file management and team collaboration platform within the Zoho ecosystem, designed for teams that already use Zoho CRM, Zoho Projects, or other Zoho apps.

Key strengths:

• $2.50/user/month Starter plan — the most affordable team cloud storage on this list
• Native integration with 50+ Zoho apps (CRM, Projects, Mail, Cliq, etc.)
• Team Folders with role-based access controls and admin analytics
• Built-in document editor (Zoho Writer, Sheet, Show) for real-time collaboration
• G2 rating: 4.4/5 with praise for value-for-money

Limitations:

• Only practical if you're already in the Zoho ecosystem — limited value as a standalone tool
• Storage limits are lower than competitors: Starter plan includes only 25 GB/team
• Third-party integrations outside Zoho are limited
• External sharing features are basic — no analytics, no watermarking, no NDA gating

Pricing: Starter $2.50/user/mo (25 GB) / Team $5/user/mo (100 GB) / Business $10/user/mo (unlimited) (Zoho WorkDrive pricing)

Best for: Small businesses and startups already using the Zoho ecosystem who want team cloud storage without paying Google or Microsoft prices.

vs. OneDrive: Zoho WorkDrive is cheaper ($2.50 vs. $6.99/user/mo) and offers built-in editing without requiring a separate Office subscription. OneDrive wins on storage capacity and third-party ecosystem. If you're choosing between Zoho and Microsoft ecosystems, WorkDrive is the more budget-friendly option.

In my experience with Zoho WorkDrive, the value is undeniable if you already use Zoho CRM. Files attached to CRM deals sync automatically, and you can generate share links from within the CRM. But the sharing links are basic — no analytics, no watermarking. For client-facing or investor-facing sharing, I still reached for Peony's branded links and personalised links.

9. Citrix ShareFile — Best for Professional Services

Citrix ShareFile is built specifically for accounting firms, law practices, and financial advisors who need client portals, e-signatures, and compliance-grade document workflows.

What it is: Secure file sharing and client portal platform designed for professional services firms. Acquired by Cloud Software Group (formerly Citrix) and positioned as an industry-specific solution rather than a general cloud storage tool.

Key strengths:

• Purpose-built client portals: branded upload/download areas for each client
• Integrated e-signatures with legally binding audit trails
• FINRA, HIPAA, and SOC 2 Type II compliant
• Workflow automation: document request templates, approval chains, auto-reminders
• Outlook plugin and Microsoft 365 integration for sending large files through email

Limitations:

• $10/user/month (Standard) starts affordable, but Advanced ($18/user/mo) and Premium ($25/user/mo) tiers add up
• The interface feels enterprise-oriented — not as intuitive as consumer tools
• G2 rating: 4.1/5 — lower than most competitors, with UX-related complaints
• Overkill for teams that don't need client portals or compliance workflows

Pricing: Standard $10/user/mo / Advanced $18/user/mo / Premium $25/user/mo (ShareFile pricing)

Best for: Accounting firms, law practices, financial advisors, and consulting firms that need structured client portals with compliance-grade security and e-signatures.

vs. OneDrive: ShareFile is purpose-built for client-facing professional services workflows; OneDrive is general-purpose storage. If you're an accountant sending tax documents to clients, ShareFile's client portal is far more professional than a OneDrive share link. For startup founders, however, ShareFile is overpriced for what it offers.

When I tested ShareFile, the client portal feature stood out — I could create a branded upload area where clients drop files directly into a structured folder. But the analytics were limited to download confirmations. I couldn't see which pages of a proposal a client read or how long they spent reviewing financial statements. For that level of insight, Peony's page-level analytics remain unmatched.

10. iDeals — Best for M&A and Due Diligence

iDeals holds a 4.7/5 G2 rating from 900+ reviews — the highest-rated virtual data room provider — and is trusted for some of the world's largest M&A transactions.

What it is: Enterprise virtual data room (VDR) purpose-built for M&A transactions, IPOs, fundraising, and regulatory compliance. Serves investment banks, law firms, and corporations managing high-stakes deals.

Key strengths:

• G2 rating: 4.7/5 from 900+ reviews — the highest of any VDR provider
• SOC 2 Type II and ISO 27001 certified with 256-bit AES encryption
• Granular permissions: 8 access levels, fence view, remote shred
• Built-in Q&A workflow for structured due diligence communication
• 24/7 in-app support with dedicated project managers for enterprise deals

Limitations:

• Custom pricing only — no published rates, and costs scale with page volume and project scope (estimated $500–1,500+/month)
• Per-page pricing model makes large document sets expensive
• Enterprise-oriented: the setup process assumes you have a deal team, not a solo founder
• No free tier or self-serve trial

Pricing: Custom (contact sales) — pricing varies by number of pages, storage, and project scope. Estimated $500–1,500+/month for mid-market deals. (iDeals pricing)

Best for: Investment banks, law firms, and corporations running M&A transactions, IPOs, or regulatory filings where compliance certifications and audit trails are non-negotiable.

vs. OneDrive: Comparing OneDrive to iDeals is comparing a filing cabinet to a vault. OneDrive stores files; iDeals manages multi-party transactions with granular permissions, audit trails, and structured Q&A. For enterprise M&A, iDeals is the gold standard. For lean deal teams and startups, Peony's free data rooms provide comparable security features without the enterprise price tag.

In my experience evaluating iDeals, the platform delivers exactly what large deal teams need: structured folders, permission hierarchies, and detailed audit logs. The Q&A feature — where buyers ask questions and sellers respond in a tracked, threaded interface — is something no general cloud storage tool offers. But for a startup founder raising a Series A, paying $1,000+/month for a VDR is hard to justify when Peony offers watermarks, NDA gating, page-level analytics, and e-signatures at $0.

From Cloud Storage to Secure Sharing

Cloud storage solves the "where do I put my files?" problem. It doesn't solve the "how do I share confidential documents professionally and know what happens after I hit send?" problem.

OneDrive, Google Drive, and Dropbox were built for internal collaboration. When you share a link externally, you get a generic URL and no visibility into what happens next. You don't know if the recipient opened it, which pages they read, whether they forwarded it, or how long they spent reviewing your materials.

Peony (free, $0) bridges this gap with AI-native data rooms purpose-built for external sharing: page-level analytics show engagement by viewer and page, dynamic watermarks deter unauthorized redistribution, screenshot protection adds another security layer, and NDA gating ensures recipients agree to terms before accessing files. Whether you're a founder sharing a pitch deck, a consultant sending a proposal, or a legal team distributing due diligence materials, Peony gives you control and visibility that cloud storage platforms were never designed to provide.

Cloud Storage vs. Secure Sharing Tools

Bottom line: Cloud storage and secure sharing solve different problems. Use Google Drive, OneDrive, or Dropbox for internal file management. Use Peony for external sharing where analytics, security, and professionalism matter — at no cost.

Frequently Asked Questions

Is OneDrive secure enough for business?

OneDrive provides AES 256-bit encryption at rest and TLS encryption in transit, which meets baseline security for internal file storage. However, it lacks page-level analytics, dynamic watermarking, screenshot protection, and NDA gating — features that professional external document sharing demands. For confidential files shared with investors, clients, or acquirers, Peony provides enterprise-grade security and visibility at $0.

What is the best free OneDrive alternative?

Google Drive offers 15 GB of free storage with strong collaboration features. pCloud gives 10 GB free with lifetime pricing options. For professional external sharing — pitch decks, financial models, due diligence files — Peony (free, $0) is the best free alternative, with AI-powered data rooms, page-level analytics, watermarks, and e-signatures included at no cost.

OneDrive vs Google Drive: which is better?

OneDrive integrates deeply with Microsoft 365 (Word, Excel, PowerPoint). Google Drive integrates with Google Workspace (Docs, Sheets, Slides). Feature-for-feature, they are comparable for internal collaboration. Both fall short for external sharing — neither provides engagement analytics, watermarking, or NDA gating. Peony fills this gap for teams that need secure, trackable external sharing alongside either platform.

Why is Microsoft retiring OneDrive standalone plans?

Microsoft announced it will retire OneDrive standalone 100 GB plans in May 2026, pushing users toward Microsoft 365 subscriptions starting at $6.99/month. The strategy bundles storage with Office apps to increase average revenue per user. If you primarily need cloud storage for external document sharing, Peony (free, $0) provides secure data rooms without any subscription lock-in.

What is the most secure OneDrive alternative?

Tresorit and Sync.com both offer zero-knowledge encryption, meaning even the provider cannot access your files. For external document sharing, Peony adds dynamic watermarking, screenshot protection, NDA gating, link expiry, and revocable access — post-delivery security controls that storage-focused platforms do not provide.

Can I use OneDrive without Microsoft 365?

Currently, yes — OneDrive offers a 5 GB free plan. But Microsoft is retiring the standalone 100 GB paid plan in May 2026, requiring a Microsoft 365 subscription ($6.99/month minimum) for more storage. The 5 GB free tier will likely remain. For teams that primarily need external document sharing, Peony (free, $0) provides unlimited data rooms without a subscription requirement.

What is the best OneDrive alternative for startups?

For internal collaboration, Google Drive is hard to beat with 15 GB free and real-time co-editing. For sharing pitch decks and fundraising materials with investors, Peony (free, $0) is purpose-built: page-level analytics show which slides investors spend the most time on, and watermarking plus screenshot protection protect your confidential materials.

Is there a OneDrive alternative with lifetime pricing?

pCloud offers lifetime plans at $199 for 500 GB and $399 for 2 TB — pay once, never pay again. Over three years, that's significantly cheaper than OneDrive or Google Drive subscriptions. For professional document sharing, Peony is free forever with no lifetime purchase needed — unlimited data rooms and sharing at $0.

What is the best OneDrive alternative for M&A due diligence?

iDeals is the leading virtual data room for M&A, with a 4.7/5 G2 rating, SOC 2 Type II and ISO 27001 certifications, and structured Q&A workflows. For lean deal teams and startups that need comparable security without enterprise pricing, Peony (free, $0) provides watermarks, NDA gating, granular permissions, and page-level analytics.

How do I migrate from OneDrive to another cloud storage?

Most alternatives support drag-and-drop upload and bulk file transfer. Google Drive, Dropbox, and Box all have migration tools for enterprise moves. For external sharing workflows, Peony requires no migration — upload your documents, and AI-powered organization structures your data room automatically in minutes.
