TL;DR:
Complex permission structures in SharePoint make it hard to track and control access. This blog covers how to improve visibility, reduce risk, and manage permissions effectively at scale. Read more…
As organizations continue to rely on Microsoft SharePoint for collaboration and document management, one challenge quietly grows in the background: permissions.
Over time, access structures become layered and difficult to follow, shaped by team changes, one-off sharing decisions, and content inherited from legacy systems.
Insights from the Microsoft Digital Defense Report highlight how identity and access remain central to security risks, yet many organizations still lack clear visibility into who can access what within their SharePoint environments.
This blog breaks down how to gain visibility into SharePoint permissions, identify access gaps, and take control of who has access to what across your environment.
Why SharePoint Permissions Become So Difficult to Manage
Permissions in Microsoft SharePoint are designed to be simple, but they don’t stay that way for long.
Several factors contribute to this complexity:
- Broken inheritance – Permissions are adjusted at different levels, which creates exceptions that are difficult to follow
- Quick sharing decisions – Files and folders are shared directly with users instead of through structured groups
- Changing teams – Employees move roles or leave, but their access isn’t always updated or removed
- Legacy content – Older permissions from systems like OpenText or Documentum are carried over during migrations
Over time, these small changes add up which makes it increasingly difficult to clearly see who has access to what.
The Visibility Problem: Who Has Access to What?
One of the biggest challenges organizations face is understanding access.
In SharePoint, a single user’s access can come from multiple sources:
- Direct permissions
- Membership in one or more groups
- Inherited access from parent sites or libraries
- Sharing links granted at different points in time
This layered model makes it difficult to answer basic but critical questions:
- Why does this user have access?
- Where was it granted?
- Is it still appropriate?

Common Permission Pitfalls to Watch For
As environments scale, certain patterns tend to repeat:
1. Over-Permissioned Users
Users accumulate access over time, especially when permissions are added but rarely removed.
2. Orphaned Permissions
Access granted to users who have changed roles (or even left the organization) remains active.
3. Excessive Unique Permissions
Too many broken inheritance points make governance nearly impossible to manage manually.
4. Uncontrolled External Sharing
Files shared externally without proper tracking introduce additional security risks.
These issues are not always visible in day-to-day operations, but they surface quickly during audits, migrations, or security reviews.
Why Migrations Make It More Complex
Content migration projects often expose permission challenges that were previously hidden.
When moving to Microsoft SharePoint:
- Legacy systems may have different permission models
- Access structures may not map cleanly
- Legacy permissions are mapped to their equivalent SharePoint permissions
Without proper analysis and validation, organizations risk:
- Replicating existing problems in the new environment
- Introducing inconsistencies in access control
- Disrupting business workflows due to incorrect permissions
This is why permissions should be treated as a core part of the migration strategy.
Best Practices for Managing SharePoint Permissions at Scale
To regain control, organizations need a more structured approach:
1. Prioritize Group-Based Access
Assign permissions to groups instead of individuals wherever possible. This simplifies management and reduces fragmentation.
2. Limit Broken Inheritance
Use unique permissions only when necessary. Keeping inheritance intact improves visibility and consistency.
3. Audit Permissions Occasionally
Conduct periodic reviews to identify:
- Excessive access
- Unused permissions
- External sharing risks
4. Document Access Logic
Establish clear rules for how access is granted, maintained, and removed.
5. Validate Permissions After Migration
Ensure that access rights are accurate and aligned with business needs.
How Tzunami Helps Simplify SharePoint Permissions
During large-scale migrations, permissions are often one of the most complex elements to handle correctly. This is where Tzunami Inc. plays a focused role.
Rather than simply transferring content, Tzunami helps organizations:
- Analyze existing permission structures before migration with pre-migration analysis
- Map permissions from legacy systems to SharePoint’s model
- Identify inconsistencies or risks in access
- Validate permissions post-migration to ensure accuracy
The goal is to make it more transparent and manageable in the new environment.
Summing Up
Managing permissions in Microsoft SharePoint is ongoing process that requires visibility and structure. As environments grow and evolve, so does the complexity of access control.
Organizations that take a proactive approach are far better positioned to maintain security, support compliance, and ensure users have the right access at the right time.
