USE CASE - LEGAL PRIVILEGE

Privilege by architecture,
not by subject line.

A purpose-built out-of-band environment for legally privileged
communications - constituted before the crisis, not scrambled
together during one.

OOB ISOLATED
NAMED ACCESS ONLY
SINGLE PURPOSE
NON-MULTI-TENANT
CRISIS-READY

 

THE PROBLEM

When it matters most, your privilege architecture is at its weakest.

Three failure modes that undermine your legal position the moment an incident begins.

Compromised channels

When a cyber incident occurs, corporate email and messaging are the systems most likely to be compromised, inaccessible, or under investigation. Legal communications sent over those channels lose their integrity.

No privilege architecture

Emails marked "Privileged & Confidential" sent to corporate inboxes accessible to IT administrators provide a weak basis for a privilege claim. Courts and regulators look for evidence of proper constitution — not just a subject line.

Crisis discipline fails

Under incident pressure, legal communications migrate to personal mobiles, WhatsApp threads, and consumer apps. None leave a credible audit trail. All are discoverable. None are out-of-band.

THE SOLUTION

Privilege by architecture, not by procedure.

The Sentinel Legal Privilege Space is an access-controlled OOB environment - provisioned before any incident, designed for a single defined function.

ISOLATED
ENCRYPTED CHAT

Privileged transcripts between legal counsel & named executives, isolated from IT & the corporate estate.

VIDEO CONFERENCE ROOM
FOR COUNSEL

Video Crisis Rooms for real-time strategy sessions with external and in-house counsel - no trace on corporate infrastructure.

PRIVILEGED DOCUMENT SHARING

Share privileged drafts, legal assessments, and board comms in a single defined Space with a clear audit trail.

CONTEMPORANEOUS
ACCESS LOG

Who was admitted, when, by who. Created at setup, not reconstructed after the fact. Producible as a privilege schedule.

NON-MULTI-TENANT
ARCHITECTURE

Your Sentinel deployment is not shared infrastructure. The Privileged Space operates independently of anything the incident has touched.

CRISIS-GRADE
RESILIENCE

Out-of-band by design. Operational when email, Teams, and corporate systems are unavailable - exactly when the Space is needed most.

THE LEGAL ARGUMENT

Why architecture satisfies the dominant purpose test.

Privilege is a legal determination. Architecture is the evidence that supports it.

For legal professional privilege to apply, the communication must have been made for the dominant purpose of obtaining or giving legal advice. Courts require contemporaneous, credible evidence that this was the case — not a retroactive argument about intent.

01

ACCESS CONTROL = PRIVILEGE SCHEDULE

The Space's named access list - legal counsel & designated personnel - maps directly to the privilege relationship. This produces a contemporaneous privilege schedule - you are not arguing after the fact: evidence was created at setup.

02

SINGLE PURPOSE = DOMINANT PURPOSE

The Space exists for one defined function: privileged legal communication. A mixed-use channel requires argument about which communications were legal in nature. A single-purpose Space makes that argument unnecessary.

03

OOB ISOLATION = EVIDENTIAL INTEGRITY

Communications in the Space sit outside the systems involved in the incident. They cannot be challenged on the grounds that the environment itself was compromised, monitored, or accessible to IT staff outside the privilege relationship.

WHY IT MATTERS - BY ROLE

One platform. Three audiences. One coherent case.

GENERAL COUNSEL / CLO
Privilege as a strategic asset

An environment constituted for privilege before the incident started. Access is controlled, purpose is defined, and the OOB architecture means the Space operates independently of whatever systems the incident has touched. You are not reconstructing a privilege argument - you are operating in a privilege environment from the first moment.

COMPANY SECRETARY
Governance and audit trail

A dedicated Legal Privilege Space creates a clear, auditable record: who was admitted, when, and on whose authority. Documents shared in the Space carry inherent provenance - created in a purpose-built privilege environment, not forwarded from a general inbox.

CFO / FINANCE DIRECTOR
Legal & Risk management

The financial exposure from a contested privilege claim -  like a regulatory investigation or class action - can dwarf the cost of the platform. If you cannot demonstrate that its legal communications were properly privileged, those communications become discoverable.

USE CASES

Five scenarios. One outcome - Legal communications protected.

  01
CYBER INCIDENT AND DATA BREACH

Legal counsel advises on notification obligations and regulatory exposure in the Space, isolated from the compromised estate. Transcripts are privileged at the outset - not reconstructed from breached servers.

  02
REGULATORY INVESTIGATION

External counsel and General Counsel communicate strategy, review documents, and prepare submissions in the Space - no crossover with IT-accessible corporate systems that regulators may seek to examine.

  03
PRODUCT LIABILITY / SAFETY EVENT

Legal team coordinates response, reviews draft public statements, and manages document production requests in a single privileged environment - with a clean access record throughout.

  04
WHISTLEBLOWER / EMPLOYMENT MATTER

HR and legal communications kept strictly separate from operational channels. Access is controlled at the individual level and a full, auditable transcript of the privileged discussion.

  05
LITIGATION HOLD / MERGERS & ACQUISITIONS

Privileged deal comms or litigation strategy sit in a defined Space with a clear, auditable access record - away from the corporate estate that may be subject to disclosure orders.

GETTING STARTED

Constituted before the crisis. Evidenced from day one.

Whether you're managing a regulatory investigation, a cyber incident, or a high-stakes litigation hold, Sentinel gives you the privileged communications environment your legal position requires - deployed fast, access-controlled from the outset, and ready before you need it.
