The Urgent Reality: Authorized Sharing Is the New Risk
In healthcare, the biggest exposure isn’t only unauthorized access—it’s what happens after an external share is authorized in Microsoft 365. Once PHI leaves your immediate control, downloads, forwarding, and AI uploads can turn sanctioned collaboration into exfiltration. Traditional tools focus on identity and access but they rarely govern what external recipients can do next.
eSHARE closes this “last‑mile” gap, often called sanctioned SaaS exfiltration prevention, by enforcing recipient‑level controls at the point of sharing and by capturing tamper‑evident audit trails you can take to auditors and the board.
How eSHARE Works, Inside Microsoft 365
eSHARE operates natively in Teams, SharePoint, and OneDrive so clinical and payer operations stay in‑platform:
⌽ No‑download for external recipients (stop onward data movement and AI uploads)
⌽ Auto‑expiry for time‑boxed access (e.g., prior‑auth evidence)
⌽ Watermarking for sensitive documents (deterrence + provenance)
⌽ Instant revoke on vendor offboarding or risk changes
⌽ Audit‑grade evidence of external recipient actions (who, when, under which policy)
Best of all, eSHARE orchestrates these controls from investments you already fund, Microsoft Purview/DLP, Conditional Access, and Zero Trust, so policy intent becomes policy execution at the moment of sharing.
High‑Impact Healthcare Workflows
➼ Prior Authorization & Evidence Exchange. Accelerate documentation flows with providers while keeping PHI governed—no‑download, expiry, and revoke when the case closes.
➼ Care Coordination & Multi‑Party Collaboration. Maintain a single source of truth in SharePoint/Teams, capture external actions for audits, and remove portal sprawl.
➼ Third‑Party Administrators, Call Centers, Consultants. Move beyond NDAs/BAAs to technical recipient controls; standardize governed links instead of risky attachments.
➼ AI Governance & Copilot Safety. Prevent the “download → AI upload” pathway for external parties; keep regulated data out of unmanaged tools while enabling AI programs safely.
Compliance Mapping: HIPAA Technical Safeguards
Auditors increasingly expect technical controls for external recipients, not just agreements. eSHARE helps align with HIPAA:
➼ Access Control: enforce no‑download/expiry/watermark/revoke for externals
➼ Audit Controls: tamper‑evident logs of external recipient actions
➼ Integrity & Authentication: prove who did what, when, under which policy
➼ Transmission Security: govern link‑based sharing and secure access paths

Frequently Asked Questions
Q1: How is eSHARE different from DLP/CASB?
Most DLP/CASB tools protect before sharing or at ingress/egress. eSHARE governs after authorization—what external recipients can do with PHI—closing the last‑mile gap inside Microsoft 365.
Q2: Will eSHARE force users into new portals or workflows?
No. eSHARE keeps collaboration inside Teams/SharePoint/OneDrive, using governed links with recipient‑level controls.
Q3: What controls can I apply to external recipients?
No‑download, auto‑expiry, watermarking, revoke, plus audit‑grade evidence of recipient actions.
Q4: How does eSHARE align with HIPAA?
It helps demonstrate §164.312 technical safeguards: access control, audit controls, integrity/authentication, and transmission security—specifically for external recipients.
Q5: Can eSHARE attach to our existing Microsoft investments?
Yes. eSHARE orchestrates controls from Purview/DLP, Conditional Access, and Zero Trust so policy intent becomes policy execution.
Q6: How do we start?
Begin with the External Data Exposure Assessment (EDEA) to quantify exposure, identify high‑risk locations, and produce a remediation blueprint tied to your Microsoft stack.
