Rethinking Secure Information Sharing in Aerospace

Introduction

In Aerospace and Defense, secure information sharing isn't optional, it's mission-critical. Organizations exchange sensitive data daily, from intellectual property to Controlled Unclassified Information, while speed and collaboration remain essential for project delivery, R&D, and operational efficiency.

The Problem with the Old Way

The traditional method — encrypting a file, sending it, and hoping it's handled correctly — is risky and inefficient. Once data leaves an organization's hands, visibility and control are gone: does the recipient manage it securely? Is it being shared further in ways that violate compliance or governance policy? These questions often go unanswered, and outdated governance models mean many organizations end up blocking link-based external sharing altogether, increasing friction and reducing productivity rather than protecting data.

The Modern Way: Share Information, Not Files

Applying Zero Trust to link-based sharing means trust is never assumed — every time a link is accessed, it's re-verified against policies that consider the context of both the data and the user. eSHARE's data-centric security model evaluates access continuously, based on contextual signals like labels, department, citizenship, and export license status, rather than securing a fixed storage location. Organizations move from a mindset of sharing files to sharing links that maintain a single source of truth: sensitive information moves, but the data never leaves the Microsoft 365 tenant, reducing the chance of data leaks while keeping every party able to collaborate.
