What’s the best VDR software for mergers and acquisitions?

We’re preparing for upcoming M&A activity and are looking for a reliable virtual data room (VDR) to manage document sharing, security, and collaboration during due diligence. We need something secure, easy to use, and capable of handling sensitive deal documents without slowing things down.

We’re hoping to find a platform that’s:

• Highly secure and compliant
• Simple for both internal teams and external partners to navigate
• Offers strong permission controls and audit trails
• Fast and reliable, even with large files and heavy use

Here are a few options we’ve been looking at on G2:

1. Datasite Diligence Virtual Data Room — Well-known in M&A circles; how smooth is the user experience?
2. Ideals Virtual Data Room — Focuses on flexibility and customization; how does it hold up under deal pressure?
3. Firmex Virtual Data Room — Popular with mid-market deals; how good is their customer support?
4. ShareFile Virtual Data Room — Known for ease of use; does it meet the security needs of M&A deals?
5. Ansarada — Focuses on AI-driven insights; does that add real value or feel like extra?

If you’ve used any of these (or others), I’d love to know:

• What made you choose that VDR?
• How was the setup and onboarding process?
• Any strengths, frustrations, or lessons learned along the way?

Hearing your experiences would really help guide our search. Thanks in advance!
