The Ultimate Guide to Secure External Sharing in 2025

Keep data in-platform. Collaborate externally—safely.

Why “in-platform” wins

Moving content to Box or Kiteworks creates copies, new silos, and compliance blind spots. eSHARE keeps files inside your Microsoft 365 tenant (SharePoint, OneDrive, Teams) so data residency, DLP, audit, and eDiscovery all stay intact. No migrations. No parallel portals. No shadow IT.

Core benefits

➥ Data residency: Content never leaves your Microsoft boundary.

➥ Data loss prevention (DLP): Microsoft Purview policies apply natively.

➥ Granular permissions: Share by user, group, domain, or sensitivity label.

➥ Secure links: Expiry, watermarking, one-time passcodes, and least-privilege defaults.

➥ Data governance: Unified logs, alerts, and reporting for auditors and CISOs.

➥ External collaboration: Guests work via Teams/SharePoint—no new tool to learn.

Common pitfalls (and how to avoid them)

➥ Over-permissioning: Fix with sensitivity labels + least-privilege presets.

➥ Untracked downloads: Use view-only links, watermarking, and expiration.

➥ Policy gaps after export: Keep files in-tenant so DLP travels with content.

➥ User friction: Avoid extra portals; extend the M365 experience they know.

Best-practice blueprint

⓵ Stay in-platform (SharePoint/OneDrive/Teams as the system of record).

⓶ Label-driven access (map sensitivity to auto policies and guest scopes).

⓷ Secure link defaults (expire + watermark by policy).

⓸ Continuous monitoring (real-time events to SIEM + scheduled attestations).

⓹ Educate and enforce (coach users at share-time; block risky actions).

Bottom line: If you run Microsoft 365, exporting files to external repositories adds risk and cost. eSHARE extends what you already trust.

The eSHARE advantage (what’s unique)

➥ Governance-native collaboration: Policies and labels drive sharing, not the other way around.

➥ Secure links that obey policy: Expiration, watermarking, OTP, domain allow/deny, and session controls.

➥ External identity, simplified: B2B guests, time-boxed access, automated recertifications.

➥ Proof for auditors: Immutable logs, fine-grained event trails, and exportable evidence.

➥ AI-ready posture: Keep source content where Copilot and Purview can govern and reason safely.
