Secure SharePoint External Sharing with 1Security

No more surprise “Anyone links,” forgotten guests, or settings buried in admin center rabbit holes. 1Security shows who has access, how they got it, and where sensitive files are exposed—so you can share confidently and pass audits without drama.

• Risky “Anyone” Links

  Users may share SharePoint files or folders via “Anyone links”, compromising confidential information and making site sharing settings hard to enforce. (Reddit, SharePoint Maven)

• Complex Guest Access

  Managing external users, new and existing guests, guest users, or external users can be complex when they lack visibility across active sites (coreview.com)

• Limited Admin Enforcement

  The SharePoint Admin Center lets admins configure organization-level and site‑level external sharing settings, but it’s tedious to monitor and ensure enforcement consistently across all active sites and site sharing settings. (Microsoft Learn)

• Default Oversharing

  Default permissions—like the ability for site members to share—may unintentionally allow external sharing, even in SharePoint sites meant to remain internal. (SharePoint Maven)

• Policy Management at Scale

  You may want to restrict external sharing at org and site levels, limit by domain, and stop specific security groups from misconfiguring—work that becomes overwhelming in large tenants (SharePoint Maven).

• Tenant-level restrictions

  Locking down sharing at the organization level reduces risk, but it also kills collaboration. Teams bypass the rules by moving files to personal OneDrives or uncontrolled platforms.

• Site-by-site reviews

  Admins attempt to check sharing settings per site collection. With hundreds of active sites, this quickly becomes unmanageable, and risky links slip through unnoticed.

• Guest account audits

  Exporting lists of external users from Entra ID or SharePoint shows who exists, but not what they actually access—leaving admins blind to real exposure.

• Custom PowerShell scripts

  Some organizations script their own reports to surface “Anyone links” or guest access. These scripts are brittle, hard to maintain, and miss context when permissions shift across nested groups and domains.

• Centralized Control

  Get one unified view of external sharing instead of wasting hours digging across many SharePoint, OneDrive, Entra, Azure, and Purview dashboards.

• Time Savings

  Free up over 70% of administrative work spent on manual checks and constant context‑switching with a single source of truth that surfaces critical sharing details instantly.

• Better Decisions

  See the full picture of sharing activity across platforms so you can act faster, smarter, and with confidence.

• Reduced Complexity

  Simplify administration by collapsing dozens of hidden settings and views into an intuitive, consolidated experience.

• Stronger Security Posture

  Quickly identify and correct sharing mishaps—defend against accidental exposure or oversharing of files and folders.

• Professional Services

  Sharing deliverables with external users - protect site sharing while fostering collaboration.

• Education / Research

  Engage students and guest users or collaborators securely without risking confidential information or oversharing to new and existing guests.

• Regulated Industries (Finance, Healthcare)

  Enforce sharing settings, maintain control over external sharing in SharePoint, and meet compliance needs without manual effort.

• Nonprofits / NGOs

  Collaborate across fast moving organization infrastructur while securing sensitive data and preventing misuse of share files workflows.
