For legal services
Privileged transfer
that doesn't show up in discovery.
Encrypt. Govern. Prove.
Law firms and corporate legal departments need a firm-wide channel for privileged documents, regulator submissions, and matter materials. Partner-controlled retention. Bar-defensible audit trails. Receipts opposing counsel can verify without contacting your IT.
THE CHALLENGE
Why the inbox is a liability
What teams in this role actually run into when secure transfer goes wrong.
01
Email is forever
Email persistence and shared-drive sprawl aren't features. They're discovery exposure. Every attachment forwarded to a personal Gmail or archived in a non-privileged channel widens the legal-hold surface.
02
Cloud platforms accumulate
Cloud-sharing platforms keep copies indefinitely by default. Convenience for the recipient, a long tail of retention obligations for the sending firm.
03
Privilege is fragile
Once a document lands on a non-privileged channel — a billing system, an outside vendor's email, a personal device — the privilege argument gets harder. The defensible answer is a channel that doesn't leave copies behind in the first place.
THE SOLUTION
What CIPH4 gives you
The product surface that maps to those problems, one feature at a time.
01
Passphrase plus single-view defaults
Passphrases hashed in the recipient's browser before they reach our servers, delivered out-of-band; one view burns the link. Use both for documents privileged on receipt.
02
Recipient identity bindingTeams
Force the recipient to verify their email via a single-use magic link before they can decrypt. Defeats forwarding when the original link is intercepted or shared.
03
Modify after sendTeams
Tighten view caps, shorten expiry, or add a passphrase to an already-shared link. Useful when an engagement scope shifts after the document is out.
04
Signed deletion receiptsEnterprise
Every Enterprise burn produces a cryptographically signed receipt anchored to the tamper-evident audit log. File it in the matter; opposing counsel can verify it on our public /verify page.
05
Tamper-evident audit timeline
Every event on every secure link — created, viewed, burned, revoked — is cryptographically chained. Any after-the-fact change to a row is mathematically detectable. Pull the per-link timeline directly into a discovery response without manual reconstruction.
06
Real-time access notification
Live dashboard update the moment opposing counsel opens the document. Email notification on every plan; tamper-evident webhook delivery on Enterprise.
THE FLOW
How a typical workflow looks
A typical sequence — from intent to evidence — in three steps.
01
Roll out
Onboard the firm via SSO (Enterprise). Set org-wide policies: maximum expiry, mandatory passphrase, recipient identity binding for matters above a sensitivity threshold.
02
Govern
Associates and partners share through the configured channel. Per-matter audit timelines roll up to firm-wide compliance reports. Bar association inquiries draw on the same hash-chained log.
03
Defend
When a matter closes — settlement, judgment, or withdrawal — pull the per-link signed deletion receipts. The closing binder gets a cryptographic destruction record that survives any later discovery interview.
THE FRAMING
Where CIPH4 fits your program
How the same building blocks land against the frameworks your auditor cares about.
01
Frameworks we map
GDPR Article 17 (right to erasure), CCPA, jurisdiction-specific privilege rules, and bar-association retention guidance. Included inside the compliance suite as ready-to-use templates with control catalogs.
02
Controls we ship
In-browser encryption (the plain document never reaches CIPH4), recipient identity binding, passphrase gating, modify-after-send, and per-link revoke. Tamper-evident audit timeline for every action.
03
Artifacts we generate
Cryptographically signed deletion receipts anchored to the tamper-evident audit log. Opposing counsel can verify them on our public /verify page.
