For M&A and due diligence teams
Stage diligence packets
and prove every copy is gone.
Stage. Track. Prove.
Bidders need to look. They don't need to keep. CIPH4 multi-file drops let you stage diligence packets, watch every view, and produce signed proof of destruction when the deal closes — or when it doesn't.
THE CHALLENGE
The problem
What teams actually run into when secure transfer goes wrong.
01
Bidders keep copies
Losing bidders walk away with the data room. Their competitive intelligence on your client's business is exactly what the client didn't want to share.
02
Tracking costs per seat
Knowing which bidder spent how long in which document usually means a paid VDR with seat-based pricing that scales with the deal team, not the deal. Wrong pricing shape for the workflow.
03
VDRs charge by the seat, not by the proof
Virtual data rooms host structured diligence well, but don't produce per-bidder destruction artifacts closing-side legal can attach to the binder. Email confirmations to destroy don't survive a discovery interview; a signed receipt does. CIPH4 works alongside whichever VDR you already use.
THE SOLUTION
What CIPH4 gives you
The product surface that maps to those problems, one feature at a time.
01
Multi-file dropsTeams
Up to 25 files per drop, each encrypted client-side. Single-file mode for one-off NDAs; multi-file for the diligence packet.
02
Advanced expiry with calendar datesEnterprise
Pick a specific closing date for each bidder's access, up to the platform's maximum link lifetime — every drop dies by day 7 from creation regardless of the date picked.
03
Modify after sendTeams
Tighten view caps as the deal narrows. The first round opens to 10 bidders; round two narrows to 3 — tighten the original links without re-staging.
04
Recipient access controlsEnterprise
Watermark, no-print, no-download overlays in the in-browser viewer (client-side; OS-level capture is not blocked). Useful as a friction layer, not a hard guarantee — the cryptographic guarantee comes from revoke and burn.
05
Real-time access notification
See exactly which bidder opened which document, when. Live dashboard update and email notification on every plan; signed webhook delivery on Enterprise.
06
Signed deletion receipts at closeEnterprise
Each bidder's link produces a cryptographically signed receipt at burn. File one receipt per bidder per closing artifact. Verifiable on our public /verify page.
THE FLOW
How a typical workflow looks
A typical sequence — from intent to evidence — in three steps.
01
Stage
Upload the diligence packet as a multi-file drop. Set view caps, expiry, and any recipient access controls. Add a passphrase delivered out-of-band.
02
Distribute
Share with each bidder. Recipient identity binding on Enterprise plans forces email verification before decrypt. Watch each bidder's access events in real time.
03
Close out
When the deal closes — or doesn't — burn each bidder's drop. Pull the signed deletion receipts and attach them to the closing binder.
THE FIT
Where CIPH4 fits your program
How the same building blocks land against the frameworks your auditor cares about.
01
Frameworks we map
Confidentiality agreements with counterparties; deal-room work has no formal industry framework regime.
02
Controls we ship
Multi-file drops (up to 25 files), advanced expiry with calendar dates, modify-after-send, recipient access controls, and real-time bidder access notification.
03
Artifacts we generate
Per-bidder cryptographically signed deletion receipts at close — each attests that the data was destroyed at a specific moment, verifiable by any party on our public /verify page.
