What Securing SharePoint Includes

Practical protection for shared files

Access Review

Know who can access files

SharePoint security starts with knowing who has access to sensitive files and why. Perimetra reviews sites, libraries, groups, shared links, and user permissions to identify unnecessary exposure. You receive plain-language findings, prioritized cleanup steps, and support for tightening access without breaking normal workflows for attorneys, clinicians, accountants, or administrative staff.

Sharing Controls

Reduce risky shared links

External sharing is useful, but unmanaged links can leave client and business data too widely available. Perimetra reviews anonymous links, guest access, sharing policies, and collaboration settings across your SharePoint environment. The outcome is a cleaner sharing model that supports legitimate collaboration while reducing unnecessary access paths and improving accountability.

Security Hardening

Improve Microsoft 365 control

Secure configuration helps reduce preventable SharePoint risk. Perimetra evaluates Microsoft 365 and SharePoint settings tied to authentication, conditional access, site controls, retention, and administrative roles. You get practical hardening recommendations, guided implementation, and documentation that helps business leaders understand what changed and why it matters.

Activity Monitoring

Detect suspicious activity

Suspicious file access, unusual sign-ins, and risky user behavior should not go unnoticed. Perimetra supports security monitoring, alert management, investigation, and response coordination around Microsoft 365 activity. Reports provide visibility into activity, findings, and remediation progress, giving you proof in every report rather than vague technical updates.

User Administration

Keep access aligned

SharePoint security depends on clean user lifecycle management. Perimetra supports account administration, onboarding, offboarding, password assistance, and access changes so permissions stay aligned with current roles. This helps reduce orphaned access, former employee exposure, and confusion when staff move between matters, departments, clients, or practice areas.

Risk Documentation

Document security progress

For firms with cyber insurance, audits, or internal governance needs, SharePoint settings should be documented and defensible. Perimetra helps translate technical controls into clear security documentation, risk findings, and remediation records. The goal is practical evidence that your firm is actively managing access, file protection, and Microsoft 365 security risk.

See Where SharePoint Risk Really Lives

SharePoint often becomes the place where client files, medical records, contracts, tax documents, and internal workflows live. That makes access control, sharing settings, and monitoring more than technical details. They affect daily operations and client trust.

Perimetra helps you understand who can reach what, where sensitive files may be exposed, and which settings need practical improvement. The focus is not bureaucracy. It is a clear picture of your risk exposure, prioritized remediation, and security controls that fit the way a small firm actually works.

Controls That Protect Files Without Slowing Work

Securing SharePoint is most effective when it combines configuration, visibility, and ongoing management. Perimetra reviews your Microsoft 365 environment, identifies risky sharing patterns, and helps strengthen the controls around your files and users.

Permission and access reviews for shared sites and libraries
External sharing analysis to reduce unnecessary exposure
Microsoft 365 security setting review and practical hardening
User onboarding and account administration support
Security monitoring for suspicious access and activity patterns
Clear reporting that shows what changed and what still needs attention
