Microsoft 365 Audit and Investigation
Auditing Microsoft 365 can feel like watching a wall of security cameras with no labels and no timeline. The footage is there, but you don’t know which screen matters, who’s in the frame, or when the real incident started. You’re forced to scrub through recordings and guess. 1Security tags every action, stitches events together, and gives you a single, searchable narrative instead of hours of silent footage.
What is the challenge?
Doing It with 1Security
Fragmented logs are like a 10,000-piece, all-white puzzle. 1Security paints in the details, giving you full M365 audit visibility for every single app.
Unified Audit Timeline
Get a single chronological view of all activity from SharePoint, Teams, and Exchange Online with complete user and permission context.
Detailed Permission Auditing
Instantly see who can access any file and how they got that permission.
Automated Evidence Reports
Generate audit-ready summaries aligned with ISO 27001, GDPR, and other compliance reporting frameworks.
Sensitive Data Link Mapping
Pinpoint where confidential files were exposed or shared externally, providing clear evidence for investigations.
Continuous Monitoring
Detect abnormal user activities, link creation, or permission changes as they happen.
AI-Ready Investigations

Risk Prioritization

Solving It with Other Methods
Many organizations use native Microsoft 365 audit tools or manual exports. It’s like auditing by fax: the report arrives slow, it’s grainy, and already outdated.
