Is Trello Safe for Project Management?
Trello is a visual project management tool owned by Atlassian that uses boards, lists, and cards for task organization. The platform benefits from Atlassian enterprise-grade security infrastructure, including SOC 2 compliance and encryption. Trello is mostly safe for team collaboration and personal task management. The primary risks involve public board exposure and the data collection inherent in Atlassian broader ecosystem. Configuring board visibility settings correctly is critical, as public boards have exposed company data in documented incidents.
What Trello Collects
- Board content including cards, checklists, attachments, and comments
- User account information and team membership details
- Activity logs showing who edited what and when
- Device data, IP addresses, and browser information
- Integration data from Power-Ups and connected services
Who Sees Your Data
- Atlassian and its subsidiaries as Trello parent company
- Board members and workspace administrators
- Power-Up developers for enabled third-party integrations
- Atlassian cloud infrastructure partners
Atlassian Security Infrastructure
As part of Atlassian, Trello benefits from the same security framework that protects Jira, Confluence, and other enterprise products. Data is encrypted in transit using TLS 1.2 or higher and at rest using AES-256. Atlassian maintains SOC 2 Type II certification and undergoes regular security audits and penetration testing. The company has a dedicated security team and a bug bounty program. Enterprise plans offer additional features including data residency controls and enhanced audit logging.
Public Board Exposure Risks
The biggest security risk with Trello is accidentally creating public boards that are indexable by search engines. Numerous companies have had sensitive information exposed through public Trello boards containing passwords, API keys, customer data, and internal project details. When creating a board, always verify the visibility setting is set to Private or Workspace rather than Public. Security researchers have discovered thousands of publicly accessible Trello boards containing sensitive corporate information, making this a real and documented risk.
Power-Ups and Third-Party Data Access
Trello Power-Ups extend functionality through third-party integrations. Each Power-Up you enable can access data on the boards where it is installed. Some Power-Ups are developed by Atlassian while others come from third-party developers with varying security practices. Review what data each Power-Up can access before enabling it, and remove Power-Ups you no longer use. For boards containing sensitive information, minimize the number of integrations to reduce the number of parties with data access.
Recommended Privacy Settings
| Setting | Where | Recommended |
|---|---|---|
| Board Visibility | Board Menu > Settings > Visibility | Set all boards to Private or Workspace visibility and never use Public unless intentionally sharing publicly |
| Power-Up Permissions | Board Menu > Power-Ups | Audit enabled Power-Ups and remove any that are not actively needed |
| Workspace Members | Workspace Settings > Members | Review membership regularly and remove former team members promptly |

Our Verdict
Trello is mostly safe for project management when boards are properly configured. Atlassian security infrastructure provides solid protection, but the risk of accidentally creating public boards is real and well-documented. Always verify board visibility settings, audit Power-Ups, and manage team membership carefully. For general task tracking and project coordination, Trello is a reliable and mostly secure tool. Avoid storing credentials or highly sensitive data directly on cards.

Frequently Asked Questions
Can anyone see my Trello board?
Only if you set the board visibility to Public. Public boards are accessible to anyone with the URL and can be indexed by search engines. Private boards are visible only to explicitly added members. Workspace boards are visible to all workspace members. Always check the visibility indicator on each board. The most common security incidents with Trello involve boards accidentally left on Public visibility containing sensitive information like credentials, internal strategies, or customer data.
Is Trello safe for sensitive business projects?
Trello is suitable for general business project management when boards are properly configured as Private and team membership is carefully managed. For highly sensitive projects, Enterprise plans offer additional controls including data residency, enhanced audit logs, and organization-wide security policies. Avoid storing passwords, API keys, or personally identifiable information directly on Trello cards. Use the attachment feature with caution and ensure Power-Ups meet your security requirements.
