If you’re evaluating enterprise collaboration tools, you’re likely comparing SharePoint, Confluence, and Notion. Each platform offers overlapping capabilities—document management, knowledge sharing, and team coordination—but their approach, pricing, compliance features, and scalability are radically different. This post breaks down where each tool excels, where they fall short, and how to choose the right fit for your organization’s needs.

Key Takeaways:

• Understand the fundamental differences between SharePoint, Confluence, and Notion in knowledge management and team collaboration.
• See side-by-side comparisons of pricing, compliance (SOC 2, ISO 27001, HIPAA), and storage/user limits.
• Discover migration and integration challenges that can impact real-world adoption and exit costs.
• Get actionable recommendations for deployment based on your team size, security posture, and collaboration needs.

Core Features and Architecture

While SharePoint, Confluence, and Notion all serve as collaborative workspaces, they take fundamentally different approaches to structure, permissions, and user experience.

SharePoint: Enterprise-Grade Document Management

SharePoint’s heritage as a document management system shows in its complex permission model, robust workflow automation, and integration with Microsoft 365 (Teams, OneDrive, Outlook). It excels in regulated industries needing fine-grained control over knowledge repositories and workflow processes. However, the UI and user experience lag behind modern SaaS-first competitors.

Confluence: Best-in-Class Knowledge Base

Confluence is widely adopted for internal wikis, technical documentation, and project knowledge sharing. Its page hierarchy, inline commenting, and macro system make it easy for distributed teams to collaborate on content. However, it lacks the advanced document management and compliance features of SharePoint, and its file handling is rudimentary.

Notion: Flexible and User-Friendly, But Limited for Large Enterprises

Notion’s strength is its flexibility: teams can build custom workflows, databases, and documentation with minimal setup. The platform’s drag-and-drop interface and database blocks are popular with startups and creative teams. However, organizations with more than 200 users often hit limitations in access control and content governance (source).

Pricing, Compliance, and Data Residency

For IT managers, the choice among SharePoint, Confluence, and Notion often comes down to cost predictability, security certifications, and data residency requirements. Here’s how they compare on the numbers:

SharePoint is the only solution with full HIPAA BAA support, making it the default choice for healthcare and regulated industries. Confluence and Notion both offer SOC 2 Type II and ISO 27001, but Notion restricts some compliance features to Enterprise plans only (source).

When considering data residency, SharePoint and Confluence provide more flexibility, which is essential for organizations subject to GDPR, CCPA, or sector-specific regulations. Notion’s EU data residency is only available at the Enterprise tier and may involve additional fees and migration effort.

Integration Ecosystem and Extensibility

Integrations and extensibility determine how well a collaboration platform fits into your existing IT environment and adapts to changing business needs. Here’s how SharePoint, Confluence, and Notion stack up:

SharePoint: Deep Microsoft Stack Integration

SharePoint’s integrations are strongest within the Microsoft 365 ecosystem—Teams, OneDrive, Power Automate, and Azure AD. It supports REST APIs, webhooks, and Power Platform connectors for custom workflows. However, integrating with non-Microsoft tools can be complex and may require third-party middleware.

Confluence: Atlassian Marketplace and DevOps Alignment

Confluence offers a robust Marketplace with 3,000+ apps for project management, diagramming, and DevOps. Native integrations with Jira, Trello, and Bitbucket make it ideal for software teams. REST APIs and webhooks are available, but automations are less powerful than SharePoint’s Power Automate and usually require separate tools.

Notion: API Maturity and Third-Party Automation

Notion’s API is less mature than its competitors but supports Zapier, Make, and custom scripts for automation. Its integration catalog is growing, but many advanced workflows still require manual setup or third-party services. Notion is ideal for teams that prioritize flexibility over deep, native integrations.

For teams with heavy DevOps or project management needs, Confluence’s integrations are hard to beat. Microsoft-centric organizations will benefit most from SharePoint’s deep stack connectivity. If you need maximum flexibility and don’t mind building some integrations yourself, Notion is a strong choice.

Deployment, Migration, and Vendor Lock-In

Deployment complexity and exit costs are often neglected in initial tool selection, but they can make or break a collaboration platform rollout—especially at scale.

Deployment Scenarios

• SharePoint can be deployed as SharePoint Online (cloud) or on-premises (SharePoint Server). Cloud deployment is strongly recommended for most organizations, as support for on-prem is being phased out. Microsoft 365 integration is seamless, but hybrid environments require significant IT overhead.
• Confluence is cloud-first, but Atlassian offers a Data Center (self-managed) edition for regulated industries. Cloud is easier and faster for most use cases.
• Notion is SaaS-only. No self-hosted or private cloud options, which may be a blocker for some regulated sectors.

Migration Effort

• SharePoint migrations (from network drives, file shares, or other DMS) are complex and often require third-party tools or Microsoft FastTrack services.
• Confluence supports import from legacy wikis (MediaWiki, Google Docs) and other Atlassian products. Migration is straightforward for small teams, but complex permission mapping can be a challenge.
• Notion offers basic CSV, Markdown, and HTML import/export. Large-scale migrations (thousands of pages or users) are labor-intensive and may require custom scripts.

Vendor Lock-In and Data Portability

All three platforms have some degree of vendor lock-in due to unique content structures and limited export options:

• SharePoint allows bulk export via OneDrive sync and PowerShell, but metadata and permissions often do not transfer cleanly.
• Confluence supports XML and PDF exports, but restoring full page hierarchies and inline comments in another tool is difficult.
• Notion’s workspace export is limited (HTML, Markdown, CSV), and advanced features like databases don’t translate well to other platforms (source).

Common Pitfalls and Pro Tips

Even experienced IT teams encounter hidden challenges when rolling out collaboration platforms. Here are the most common traps—and how to avoid them:

• Overengineering Permissions (SharePoint): Complex nested permissions and group inheritance can result in accidental data leaks or orphaned content. Best practice: Use flat permission structures and audit regularly.
• Underestimating Content Sprawl (Confluence, Notion): Without strict page naming and archiving conventions, wikis quickly become unmanageable. Enforce content ownership and periodic cleanup policies.
• Ignoring Storage Quotas (Confluence Standard): 250 GB sounds like a lot, but design teams or video-heavy documentation can exceed this rapidly. Monitor storage usage and plan for upgrades.
• Assuming Feature Parity Across Pricing Tiers: Notion’s most advanced security and compliance features are only on the Enterprise plan. Review feature matrices carefully before committing (source).
• Neglecting Integration Roadblocks: SharePoint integrates best with Microsoft products; mapping existing Jira/Trello workflows into SharePoint is rarely seamless. Test critical integrations before full rollout.
• Migrating Without a Cleanup Phase: Migrating legacy content “as-is” leads to junk data and poor adoption. Inventory and clean up before moving to any new platform.

Conclusion & Next Steps

Choosing between SharePoint, Confluence, and Notion requires more than ticking off feature checklists—you need to align each platform’s strengths with your team’s collaboration style, compliance needs, and integration landscape. For Microsoft-centric, compliance-heavy environments, SharePoint is the default. Confluence shines for technical teams and documentation-heavy workflows. Notion is unbeatable for fast-moving, less regulated teams that need ultimate flexibility.

Before committing, pilot your top choice with a real team, map out your integration and migration path, and budget for the inevitable hidden costs.
