Miro Hardening Guide

Productivity Last updated: 2025-12-14

Visual collaboration security for board sharing, app controls, and export restrictions

Product Docs API Docs Hardening Guide

Overview

Miro is a visual collaboration platform for whiteboards, diagrams, and design sessions. REST API, OAuth integrations, and public board sharing handle sensitive planning documents and architecture diagrams. Compromised access exposes strategic planning, product roadmaps, and internal processes.

Intended Audience

  • Security engineers managing collaboration tools
  • Miro team administrators
  • GRC professionals assessing visual collaboration security
  • Third-party risk managers evaluating design tool integrations

How to Use This Guide

  • L1 (Baseline): Essential controls for all organizations
  • L2 (Hardened): Enhanced controls for security-sensitive environments
  • L3 (Maximum Security): Strictest controls for regulated industries

Scope

This guide covers Miro security configurations including authentication, access controls, and integration security.
