Secure Enterprise Access Reviews in Microsoft 365
Secure enterprise sharing with access reviews for Microsoft 365 Collaboration platforms such as Microsoft 365 have transformed workplace dynamics by enabling seamless document exchange among employees, clients, and partners.
Security Challenges
However, the ease of cloud-based sharing introduces significant security challenges. As organizations increasingly rely on tools like Teams, SharePoint, and OneDrive for real-time collaboration, the risk of uncontrolled data exposure grows. The proliferation of cloud sharing features has outpaced visibility into who accesses sensitive information. Security teams often lack clarity on who has been granted access to shared files, creating vulnerabilities that threat actors could exploit.
Survey Insights
A survey by Wire revealed that 61% of security professionals reported shared file access remaining active beyond its intended duration, while 34% struggled to identify who had access to critical data. The contextual nature of cloud sharing complicates risk management. Employees frequently share files for specific tasks, such as project coordination or client approvals, but access permissions often persist long after the original purpose is fulfilled. For example, a contractor may be removed from a project, yet their access to shared folders remains active. Similarly, new members added to a Teams channel might inadvertently gain access to all files within that workspace.
Native Tools Limitations
Microsoft 365 offers two native reporting tools for monitoring shared data, but both have significant limitations. The SharePoint Advanced Management feature generates a global report on new sharing links created in the past 28 days, but this metric alone lacks actionable context. A spike in shared links could indicate misuse or simply reflect legitimate project activity, such as onboarding external vendors. The site-level sharing report provides detailed lists of shared files and users but requires manual aggregation across multiple SharePoint and OneDrive instances, making it impractical for large organizations. The absence of a centralized dashboard for access governance forces security teams to perform labor-intensive analysis. This gap in visibility leaves organizations vulnerable to prolonged exposure of sensitive data.
The Solution with tenfold
To address these challenges, dedicated Identity and Access Governance (IAG) solutions like tenfold offer advanced tools for managing shared content. These platforms provide unified visibility into files across Teams, OneDrive, and SharePoint, enabling administrators to identify and remediate risks efficiently. Key capabilities include a centralized overview of all shared content, with filters to analyze data by application, user, or site. Visual indicators highlight potential issues, such as files shared outside their designated Teams channels. Additionally, tenfold streamlines the access review process by prompting file owners to verify and adjust permissions. Each reviewer receives a tailored dashboard of shared items, allowing non-technical users to confirm or revoke access without requiring IT intervention. By combining comprehensive visibility with automated review workflows, tenfold helps organizations leverage cloud collaboration tools while minimizing exposure risks. This approach ensures that shared access aligns with business needs and security policies, reducing the likelihood of data breaches.
