Real, measurable outcomes for your organization.
Know exactly who consumes what
See exactly what’s taking up space across OneDrive, SharePoint, and Teams, and who owns it: granular visibility by user, department, country, and entity.
Know where to act before your next invoice
Prioritized recommendations pinpoint what to clean up first:
Oversized and obsolete files
Unaccessed data and inactive spaces
Redundant file versions eating up quota
Total recoverable storage, quantified
Eliminate unnecessary, obsolete, and redundant data
IT removes thousands of files in bulk. Data owners clean up their own spaces through guided campaigns. Measure, prove, and communicate the impact — before and after.
Cleaner data. Faster collaboration. Better AI.
Lean data lifecycle management means your collaborative spaces stay relevant and performant and your AI tools only surface what’s actually worth surfacing.
Turn data hygiene into a company-wide movement
Recurring cleanup campaigns, measurable progress, and internal reporting on results — give your teams a reason to act, and your leadership a story to tell about responsible digital practices.
Assess Your M365 Storage

What does a typical deployment look like? What permissions are required for the solution ?
The solution is available as soon as the API connection is established. No complex integration, no agents to deploy.
How do you ensure full traceability of corrective actions for our auditors ?
All actions, whether performed by users or by administrators are logged with a timestamp, the initiator’s identity, the resource involved, and the action taken. These logs are retained for the duration of the contract, can be exported, and are available for review to meet audit and compliance requirements.
How do you measure the effectiveness of a campaign ?
Dashboards provide tracking data before, during, and after each campaign: the number of targeted users who participated, the number of corrections made, the profile validation rate, a day-by-day participation trend, and a breakdown by entity, country, or department. These metrics enable precise oversight by the governance committee.
Is your solution self-hosted? What guarantees do you offer regarding hosting?
IDECSI is a French software publisher. The platform can be hosted on Azure France using dedicated infrastructure, on OVHcloud with SecNumCloud certification, or, in the near future, on Bleu Cloud (SecNumCloud based on Azure technology). In all cases, the infrastructure is dedicated to the customer and the data is strictly located within the EU.
