Introduction
Trustifi is hosting a webinar on 13 August 2026 addressing security gaps in Microsoft 365 collaboration tools. The session targets managed service providers and IT security professionals responsible for protecting enterprise environments where Teams, OneDrive, and SharePoint have become integral to daily operations. As organisations increasingly rely on these platforms for internal communication and file sharing, the attack surface has expanded well beyond traditional email vectors.
The Expanding Attack Surface in Collaboration Platforms
Microsoft 365 has evolved from a productivity suite into the operational backbone of most modern enterprises. While email security has received substantial attention and investment over the past decade, the rapid adoption of collaboration tools has created new entry points that threat actors are actively exploiting. Teams messages can carry malicious links, OneDrive folders may harbour compromised files, and SharePoint sites can become vectors for lateral movement within an organisation.
Native Microsoft 365 security controls provide baseline protection, but organisations frequently discover visibility gaps when attempting to monitor activity across all collaboration channels simultaneously. The challenge intensifies for managed service providers overseeing multiple client tenants, where inconsistent security configurations and varying compliance requirements demand a more unified approach to threat detection.
Addressing Risky Sharing and Data Exposure
Beyond external threats, collaboration tools introduce significant data governance challenges. Employees routinely share files containing sensitive information through OneDrive links or SharePoint sites, sometimes with external parties or overly permissive access settings. These sharing behaviours, while often unintentional, can result in regulatory violations or competitive exposure.
The webinar will examine methods for identifying sensitive data exposure across Microsoft 365 collaboration environments. This includes detecting when confidential documents are shared inappropriately and understanding the full scope of access permissions across an organisation’s file repositories.
Unified Incident Investigation
Security teams investigating potential breaches often struggle with fragmented visibility when threats span multiple Microsoft 365 services. An attack that begins with a phishing link in Teams may propagate through shared OneDrive files before establishing persistence in SharePoint. Investigating such incidents requires correlating activity across all affected platforms from a centralised vantage point.
The session will demonstrate how consolidated investigation capabilities can reduce response times and improve the accuracy of threat assessments when dealing with cross-platform security incidents.
Who Should Attend
This webinar is designed for managed service providers seeking to enhance their Microsoft 365 security offerings, as well as IT security professionals responsible for protecting collaboration environments. Those evaluating supplementary security solutions for Microsoft 365 deployments will find the session particularly relevant, as will compliance officers concerned with data exposure risks in file-sharing workflows.
