Board Portals & Boardroom Data Rooms

Board portals are a specialised cousin of the virtual data room. They support recurring meeting cadences (board, committees, supervisory board), distribute meeting packs under granular permissions, capture decisions in a defensible log, and meet the same controls a VDR satisfies for an M&A transaction.

European listed companies, large privately held groups, and regulated entities (banks, insurers) increasingly use dedicated board portals: most prominently Sherpany (Switzerland) and Brainloop (Germany, now Diligent): alongside their transaction VDRs.

This page covers what a board portal is, how it differs from a transaction VDR, and which providers are typically chosen for European board use.

Board Portal Features

  • Meeting lifecycle: agenda, papers, attendance, minutes, action tracking.
  • Granular permissions: per board / committee / member.
  • Annotated reading: offline-capable readers; annotations sync.
  • Decision log: searchable, defensible record of resolutions.
  • Two-factor authentication and SSO.
  • EU / Swiss data hosting: typical for European listed companies.

Board Portal vs Transaction VDR

A board portal optimizes for recurring use, single-user accessibility (each director has their own account for years), and meeting workflows. A transaction VDR optimizes for short-burst use, large reviewer groups, Q&A workflow, and per-deal permissions. Many European groups run both: a board portal for ongoing governance, a transaction VDR per deal.

A third layer sits between them: the confidential paper that has to reach people who hold no portal seat, such as a transaction committee, an incoming supervisory-board member, or the lead investor entitled to observe. Groups increasingly handle that with a secure link-based room such as Papermark rather than by attaching the pack to an email, because each recipient gets a separately watermarked, expiring, view-only copy and the access record can be exported into the board file.

Providers Used by European Boards

  • [Papermark](/providers/papermark): not a meeting-management portal, so it does not replace one. It is best for the board-adjacent distribution around the portal: circulating a deal pack to a transaction committee, sending an investor update to observers without portal accounts, or issuing a single confidential paper under NDA-before-access. EU hosting in ISO 27001-certified Frankfurt data centres, SOC 2 Type II and GDPR compliant, per-recipient dynamic watermarking, link expiry after the meeting, and page-by-page analytics showing who opened the pack and how far they read before the session.
  • [Sherpany](/providers/sherpany): Swiss; widely used by European listed companies.
  • [Brainloop](/providers/brainloop): German; now part of Diligent.
  • [Admincontrol](/providers/admincontrol): Nordic; combines a board portal with a VDR.
  • [idgard](/providers/idgard): for highly regulated sectors with §203 StGB sensitivity.

Frequently Asked Questions

Should we use a transaction VDR or a board portal for board meetings?

A board portal. Transaction VDRs are optimized for short-burst, multi-bidder workflows; board portals are optimized for recurring meeting cadences, decision logs, and director-friendly readers.

Does Sherpany count as a virtual data room?

Sherpany combines board portal and VDR-grade document controls. For ongoing governance and meeting management, it functions as a board portal; for transaction-grade DD with multiple bidders, a dedicated VDR is the better fit.

Are board materials personal data under GDPR?

Director identities and commentary are personal data; some materials may be special-category. EU hosting and tight access controls are the baseline.
