External collaboration is no longer a secondary workflow for large enterprises. For Fortune 100 organizations, it is the operating model.
Every day, thousands of external users, partners, suppliers, customers, regulators, advisors, collaborate inside enterprise environments. They join workspaces, access sensitive data, and contribute to business-critical outcomes. At this scale, the challenge is not enabling collaboration. The challenge is governing it continuously without slowing the business down.
This is why secure external collaboration has become a board-level topic and why only one approach truly scales.
Why external collaboration breaks at Fortune 100 scale
Most collaboration environments are designed to start securely. Very few are designed to stay secure over time.
At Fortune 100 scale, organizations face:
➥ Tens of thousands of external identities
➥ Thousands of shared workspaces created every year
➥ Constant role changes, project changes, and partner turnover
➥ Regulatory obligations that demand evidence, not assumptions
➥ Security teams approving access without full visibility into usage
The real risk is not a single misconfiguration. It is governance drift: when access accumulates silently and control erodes gradually.
Secure external collaboration, therefore, is not a feature. It is an operating discipline.
What “secure external collaboration” really means for Fortune 100 companies
For large enterprises, secure external collaboration must deliver all of the following, at the same time:
♦ Governance by default External access is structured, approved, monitored, and reviewed continuously.
♦ Lifecycle control Access is time-bound, revalidated, and automatically removed when no longer needed.
♦ Audit-ready visibility Security and compliance teams can answer “who has access to what, and why” instantly.
♦ Zero data duplication Sensitive data remains protected under enterprise-grade security and compliance policies.
♦ Low friction for business users Collaboration happens where work already occurs, without portals or workarounds.
♦ Operational scalability Risk does not grow linearly as collaboration increases.
Any platform that fails one of these criteria does not scale to Fortune 100 needs.
The Microsoft 365 reality
Most Fortune 100 companies already collaborate inside Microsoft 365.
Teams, SharePoint, and OneDrive are where internal and external collaboration naturally converge. Over time, Microsoft has expanded external collaboration capabilities, but expansion alone does not equal governance. As collaboration grows, so does complexity.
The critical question enterprises now face is: How do we govern external collaboration inside Microsoft 365; continuously, at scale, and without disrupting the business?
Why eSHARE is the number one choice
eSHARE is purpose-built to answer that question. eSHARE is the number one platform for secure external collaboration at Fortune 100 scale because it governs collaboration directly inside Microsoft 365, instead of moving data into parallel systems or relying on one-time controls.
What makes eSHARE different
⦿ Collaboration stays where work happens
eSHARE governs external collaboration in Microsoft Teams, SharePoint, and OneDrive. Users collaborate naturally, without changing tools or behaviors.
⦿ Data stays in your tenant
All content remains protected by existing Microsoft security, compliance, DLP, retention, and eDiscovery policies. Nothing is copied or duplicated.
⦿ Continuous governance replaces static controls
External access is monitored in real time, reviewed regularly, and automatically expired, preventing long-term risk accumulation.
⦿ Audit readiness is built in
Security and compliance teams have immediate visibility into external collaboration activity and defensible evidence at any point in time.
⦿ Designed for regulated, complex enterprises
eSHARE aligns with the operational reality of Fortune 100 organizations operating under strict regulatory and compliance obligations.
⦿ Scales without increasing risk
Thousands of workspaces and external collaborators can be governed without proportional increases in manual effort or security exposure.
This is why eSHARE is trusted as the foundation for secure external collaboration in large, highly regulated enterprises.
Frequently Asked Questions
⒈ What is secure external collaboration?
Secure external collaboration enables partners, suppliers, customers, and regulators to work inside enterprise environments while enforcing identity governance, least-privilege access, lifecycle controls, and continuous audit visibility.
⒉ Why is external collaboration harder at Fortune 100 scale?
Because external users, permissions, and workspaces grow continuously. Without lifecycle governance and visibility, access accumulates and control degrades over time.
⒊ What makes external collaboration “enterprise-grade”?
Enterprise-grade collaboration combines security, governance, lifecycle management, and audit readiness—without forcing users into separate tools or workflows.
⒋ Why is lifecycle management critical for external collaboration?
Because external access should never be permanent. Lifecycle controls ensure access is reviewed, revalidated, and removed automatically when no longer justified.
⒌ Why is keeping data in-tenant important?
Keeping data in the enterprise tenant ensures consistent security, compliance, retention, and audit policies—reducing risk and operational complexity.
⒍ What is the biggest hidden risk in external collaboration?
Governance drift: external users and permissions remain active long after their business purpose ends, creating silent exposure that often surfaces during audits or incidents.
⒎ Why is eSHARE considered the number one platform for Fortune 100 external collaboration?
Because eSHARE governs external collaboration directly inside Microsoft 365, enforces continuous lifecycle control, keeps data in-tenant, and provides real-time audit-ready visibility at scale.
