Is this the same as a vendor due diligence room?

No. Vendor diligence rooms are usually inbound—you reviewing a supplier. A customer security review packet is outbound—you sending SOC 2 reports, policies, and architecture answers to a buyer evaluating you.

How is this different from questionnaire answer guides?

Questionnaire posts help you phrase encryption and key-custody answers. This playbook is about packaging and delivering the evidence files themselves without a forever shared folder.

Can we just put the SOC 2 PDF in Google Drive?

You can, but guest links and broad folders tend to linger after the deal. Prefer a sealed packet with expiry and revoke when the review closes or the buyer walks.

What should be in a security review packet?

Typically: current SOC 2 / ISO report (or bridge letter), high-level architecture, encryption and key-custody summary, subprocessors list, incident response overview, and named contacts—not your entire confluence wiki.

Will a sealed vault make us pass every security review?

No. Buyers still score your controls. The vault reduces sharing sprawl and gives you a cleaner access story while the review is open.

Customer Security Review Packets Without a Forever Folder

Enterprise buyers do not just ask “are you encrypted?” They ask for packets: SOC 2 reports, subprocessor lists, architecture diagrams, and policy PDFs—often on a deadline, through a security questionnaire portal, and with a procurement team that will forward anything you attach.

This guide is for outbound customer security review evidence—how to ship a sealed packet without creating a forever folder of your trust materials. It is not our vendor diligence-room post (inbound supplier review) and not our questionnaire wording guide (how to answer encryption questions).

Why security review sharing goes wrong

1. One Drive folder for every RFP

Teams clone last year’s “Security package” folder, add the new SOC PDF, and invite another guest domain. Six months later you cannot say which buyers still have access. Contrast with a sealed link per review.

2. Emailing the SOC 2 as an attachment

The report lands in procurement inboxes, ticket systems, and personal forwards. You cannot revoke an attachment. Prefer a controlled link: stop emailing sensitive attachments.

3. Oversharing the wiki

Dumping Confluence or Notion into a zip “to be helpful” expands blast radius. Ship a curated evidence set. Keep living docs internal; export only what the questionnaire asks for.

4. No activity when legal asks who saw what

After a deal dies—or closes—you may still need a trail of who opened the packet. Generic cloud links rarely match what reviewers expect. See what auditors ask for.

Build a reusable evidence kit (not a living dump)

Current attestation report or bridge letter
One-page architecture / data-flow summary
Encryption and key-custody summary aligned with questionnaire encryption answers
Subprocessors / subprocessor list pointer
Incident response overview and security contact

Version the kit quarterly. For each buyer, copy into a sealed share—do not grant standing access to the master library.

Outbound sealed-packet workflow

Assemble the buyer-specific set (omit irrelevant internal runbooks).
Upload into a zero-knowledge vault—encrypt in the browser before storage.
Mint a sealed link with a review-length expiry (often 14–30 days, not “forever”). Tighten with expiry policy.
Paste the link into the questionnaire portal or email. Keep chat for nudges only.
Revoke when the review closes, the buyer chooses a competitor, or the report is superseded. Refresh the kit; do not leave stale SOC PDFs open.

Where this sits vs other rooms

Vendor diligence rooms — you reviewing suppliers.
External auditor sharing — attestation fieldwork packets.
This post — buyers reviewing your trust materials.

What Compliance Locker changes

Compliance Locker seals outbound security packets with client-side encryption, expiry, revoke, and activity—so your SOC PDF is not another immortal guest folder. It does not write your policies for you. Start on pricing or read security and trust.
