Sensitive Meeting: 30-Minute Anti-Leak Checklist (Offices, Management, Firms)

Who is this checklist for?

• management (CEO, CFO, HR Director),
• firms (lawyers, consultants, experts),
• project teams (acquisition, tender, crisis),
• any organization organizing a “high-stakes” meeting.

1) The 5 Minutes That Change Everything: Frame the Meeting

Before touching anything, establish 4 elements. This prevents 80% of errors.

• Exact subject: what must remain confidential?
• Participants: who needs to be present, who does not need to be there?
• Location: fixed room or temporary location?
• Sensitivity level: “important” or “critical” (it is not the same).

Simple advice: the more critical it is, the more you reduce the surface area (fewer people, fewer locations, less equipment).

2) “Meeting Room” Checklist (10 Minutes)

Access and Environment

• Close the room and limit entries/exits during the meeting.
• Avoid “high-traffic” rooms (near reception, heavily frequented corridor).
• If possible, choose a room with minimal equipment and few objects.

Objects and Equipment (Without Paranoia)

• Remove unnecessary objects from the table (gifts, cases, unknown accessories).
• Simply verify that there have been no obvious recent additions (“extra” power strip, unknown charger).
• If you have a video conference room: note the equipment present (useful if you need to conduct an audit later).

Documents

• Prepare a “meeting” version: only what needs to be shared.
• Avoid printouts left on site after the meeting.
• Simple rule: all sensitive documents leave with their owner.

3) “Participants” Checklist (5 Minutes)

Strictly Necessary

• People “in the know” are not necessarily “necessary.”
• Avoid broad invitations “for convenience.”

Basic Rule (Very Effective)

• A single reporting channel (one responsible person).
• No “quick summary” in the open space afterward.

Phones: A Simple Rule

You are not required to make a ritual. But if the meeting is critical:

• silent mode and screens turned over,
• or phones off the table,
• or (if very critical) phones outside the room.
• it is possible to place phones in a Faraday cage in pouch form

The objective is to avoid distractions and involuntary leaks, not to treat people like suspects.

4) “Before / During / After” Checklist (10 Minutes)

Before

• Do not announce the meeting subject to too many people.
• Avoid discussing sensitive points in common areas “while waiting.”
• If you already suspect a leak, avoid discussing it in the room in question.

During

• Keep the meeting structured: fewer digressions = fewer involuntary leaks.
• Pay attention to “detail” phrases (amounts, dates, names): these are the information that leaks most.

After

• Clean the room (documents, post-its, flipchart, trash).
• A single channel for distributing the minutes.
• If a decision is sensitive: share it on a “need-to-know” basis.

5) The 7 Classic (and Costly) Errors

1. Changing rooms at the last minute “randomly.”
2. Holding the meeting in an overly equipped, overly shared room.
3. Leaving sensitive documents on site.
4. Multiplying participants to “move quickly.”
5. Discussing the subject before/after in common areas.
6. Accusing someone without factual basis.
7. Improvising homemade tests (consumer-grade detectors, disassembly).

6) When a Checklist Is Not Enough (and an Audit Becomes Relevant)

A checklist primarily protects against involuntary leaks. It does not replace verification if:

• you already have repeated and targeted leaks,
• the same location recurs in the timeline,
• a conflictual context exists (internal/external),
• the stakes are too high to take a risk.

In this case, a targeted TSCM detection (room + management) is often the best efficiency/time ratio:
