The two biggest names in virtual data rooms compared. And when mid-market advisors should look at a third option.
Last updated: April 2026
Intralinks (by SS&C) and Datasite are the two dominant enterprise VDR platforms. Datasite leads in M&A with AI document analysis. Intralinks is stronger in debt capital markets and structured finance. Both are enterprise-grade, enterprise-priced, and enterprise-complex. For mid-market advisors and professional services firms, Alkmist offers the coordination layer that neither VDR provides — at a price and complexity level that actually fits.
How both platforms stack up across the capabilities that matter most.
| Feature | Alkmist | Intralinks |
|---|---|---|
| Primary focus | Enterprise VDR for M&A | Enterprise VDR + debt capital markets |
| AI features | AI doc categorization + redaction | AI-powered insights and analytics |
| M&A strength | Market leader for sell-side M&A | Strong but second to Datasite in M&A |
| Debt markets | Adequate | Market leader in DCM |
| Global coverage | Global data centers | Global data centers |
| Security | SOC 2, ISO 27001 | SOC 2, ISO 27001 |
| Request management | Basic request tracking | Basic request tracking |
| Adaptive follow-ups | Not included | Not included |
| Client portal | VDR access only | VDR access only |
| Multi-industry use | M&A and capital markets only | M&A and capital markets only |
| Pricing | Enterprise pricing | Enterprise pricing |
Intralinks and Datasite both solve the document security and access control problem at enterprise scale. The choice between them typically comes down to transaction type: Datasite for sell-side M&A, Intralinks for debt capital markets.
But neither platform was built for coordination. Getting the right documents from the right people on time, managing multi-party workflows, sending adaptive follow-ups that don't damage relationships — that's a different problem. For mid-market advisors and professional services firms, Alkmist provides the coordination layer at a fraction of the cost and complexity.
Different tools fit different workflows. Here's our honest assessment.
