Calculate SavingsStop Renting Storage Tiers for Every Deal
Govern 365 is the only FirmRoom alternative that gives you Unlimited Data Rooms. Unlimited Storage. Unlimited Users. One Flat Annual Fee - all inside the Microsoft 365 tenant you already pay for.The “Storage Tier Cliff” is Quietly Costing You More Than You Think
FirmRoom’s flat-rate, per-storage-tier pricing is a real improvement on legacy per-page VDRs. But it caps you in ways most teams discover only after they sign:
- One data room per plan. Running two parallel deals? That’s two subscriptions. Three deals? Three.
- $150 per GB / month in overage charges. Exceed your 2/5/10 GB tier mid-deal and the meter starts running per gigabyte. Per month.
- A 10 GB ceiling. Larger or document-heavy transactions push you off FirmRoom entirely and into DealRoom’s $20K+/year tier.
- Monthly-only billing on a credit card. Easy to start, painful to scale through procurement.
For teams running multiple deals a year, monthly tiers quietly add up to annual contracts – and the data never comes home.
See how much you can reclaim by switching to a VDR that is native to your Microsoft 365 environment.

Bank-Grade Security. Built on Microsoft Purview
Your CISO doesn’t want another third-party AWS bucket to vet. FirmRoom is hosted in AWS with AES-256 encryption and SOC 2 – solid for a stand-alone tool, but it puts another vendor between your deal documents and your data-loss-prevention boundary.
Govern 365 orchestrates Microsoft Entra ID and Sensitivity Labels to lock down your data without it ever leaving your tenant. Your existing Microsoft 365 certifications – SOC 1/2/3, ISO 27001/27017/27018/27701, FedRAMP High, HIPAA, HITRUST, GDPR, PCI DSS – are the certifications that govern your deal data. No new vendor risk review. No new DLP gap.
Frequently Asked Questions
FirmRoom publishes three monthly tiers: 2 GB at $395/month, 5 GB at $695/month, and 10 GB at $995/month – each covering exactly one data room. Exceed your tier and overage is $150 per GB per month. A team running three concurrent deals on the 5 GB tier pays roughly $25,020 per year, before any overage. Govern 365 is a flat annual subscription with unlimited data rooms, unlimited users, and unlimited storage, layered on the Microsoft 365 capacity you already pay for. The cost gap widens with every additional deal and every gigabyte you bring on board.
FirmRoom’s published policy bills overage at $150 per GB per month, prorated by day. A bidder requesting one additional 2 GB folder mid-diligence can add $300/month to your bill until the deal closes. With Govern 365, your storage limit is the storage capacity of your own Microsoft 365 tenant – there is no per-GB meter and no overage line item, because we don’t host your data.
Yes. A single Govern 365 subscription covers an unlimited number of data rooms, including parallel deals across different teams, business units, or advisors. FirmRoom’s published plans are scoped to one data room per subscription, so a second simultaneous deal generally requires a second plan or an upgrade path into DealRoom (starting at $20,000/year).
Because deal content stays in your Microsoft 365 tenant, the certifications that govern your data are Microsoft 365’s – including ISO 27001, ISO 27017, ISO 27018, ISO 27701, SOC 1/2/3, FedRAMP High, HIPAA, HITRUST, GDPR, PCI DSS, and a long list of financial-services and government frameworks. FirmRoom is SOC 2 certified and hosted on AWS with AES-256 encryption, which is solid for a stand-alone SaaS tool but a narrower posture than the Microsoft 365 footprint Govern 365 inherits. Govern 365 itself, as a zero-knowledge governance layer, has SOC 2 certification underway, slated for H1 2026.
Yes – and beyond it. FirmRoom’s sweet spot is transactions in the $5M-$500M range. Govern 365 runs on SharePoint Online, which already handles the document workloads of the Fortune 500 at scale far larger than any single transaction. The platform is equally comfortable powering a $20M capital raise and a $500M+ M&A diligence, with the same flat annual fee. The one scenario where a stand-alone VDR may still apply is when a sell-side advisor mandates a specific platform as part of their standard process.
FirmRoom’s published plans are monthly subscriptions – the moment you stop paying, you lose the workspace. To retain access, you keep paying the monthly tier indefinitely, which functions as an implicit archive fee. Govern 365 auto-archives every closed deal back into your own SharePoint tenant, governed by your retention policies. Your deal record stays with you, on infrastructure you already own, for $0 in additional archive cost.
