Reduce oversharing and overpermissioning
Ongoing data hygiene on Microsoft 365 driven by employees, not by a once-a-year project.
Oversharing and overpermissioning accumulate one reasonable decision at a time.
Every major framework, NIST CSF, ISO 27001, SOC 2 Type II, and every applicable privacy regulation, GDPR, Law 25, CCPA, PIPEDA, requires managing access to sensitive data on an ongoing basis. Yet, most organizations still review it only once or twice a year. Sheer data volume used to make sensitive files hard to stumble on by accident. AI is removing that accidental protection.
of organizations cite security and governance as their top challenge to deploying Microsoft 365 Copilot, caused by sprawl, oversharing, and data loss
Gartner, January 2026Data hygiene isn't a project. It's a habit.
Contextual nudges
Teams notifications sent straight to the person who created the share.
Prioritized shares
A ranked list of risky shares. Revoke one, revoke all, or extend the ones still needed.
Micro actions
Under two minutes a week, no separate portal to log into.
Owner-led access reviews
SharePoint and Teams site owners confirm who still belongs as an owner, member, or guest, on a schedule IT sets.
Self-directed archiving
Teams and SharePoint site owners archive what they no longer need by removing all memberships, shares, and access rights at once.
Sustained engagement
Badges and light gamification keep the habit alive past the first month.
Watch risky shares drop
From completion rates to real risk reduction
Boards and regulators increasingly ask for evidence, not policy. WeActis reframes what security leaders can report.
Why IT alone can't produce that evidence
IT-led remediation cannot produce that evidence at scale: it lacks the business context to judge whether a share is still needed, and centralizing the decision only adds to the backlog. Real reduction happens when the person who created the share, and who actually has the context, makes the call instead.
The personal stakes are rising for security leaders
Regulators are increasingly naming individuals, not just organizations. The 2023 SEC case charged a sitting CISO personally over cybersecurity disclosures. NYDFS Part 500 requires personal attestation. D&O insurance frequently does not cover the CISO or CCO personally in these cases.
Questions we hear a lot
What is oversharing in Microsoft 365, and why does it matter?
Oversharing is when content in Microsoft 365 is accessible to more people than intended through broad sharing links, permissive group memberships, or forgotten guest access. It matters because Microsoft 365 Copilot and agentic AI surface whatever a user can technically access, meaning existing oversharing instantly becomes an AI data exposure risk.
How is WeActis different from annual security awareness training?
Training builds awareness. WeActis changes behavior by turning a ranked list of risky shares into completed remediation actions, on an ongoing cadence, directly inside Microsoft Teams. The difference shows up in metrics: revoked shares, not quiz completion rates.
What can we report to our board after deploying WeActis?
Real reduction. For example: employees revoked 12,000 unnecessary shares last quarter, the percentage of externally shared files dropped by 34%, or average risk exposure per employee decreased by half. WeActis gives you the numbers, not just the activity.
Does WeActis work alongside Microsoft Purview to reduce oversharing?
Yes. WeActis is complementary to Purview: it reduces oversharing whether or not classification is finished, using share-level signals. When Purview matures, WeActis enriches its risk model with sensitivity labels automatically.
How much time does WeActis ask of employees?
Under two minutes a week, with no separate portal to log into. WeActis delivers prioritized share lists inside Microsoft Teams, and employees can clear their queue in a couple of clicks using express revocation.
Can WeActis reduce oversharing without sensitivity labels or Purview classification?
Yes. WeActis scores risk using structural signals — link type, permission level, share duration, and guest presence — so it can start reducing oversharing immediately, before any classification program is in place.
How does WeActis protect against Copilot over-surfacing overshared data?
By reducing the access footprint before Copilot is deployed. WeActis systematically guides employees to revoke unnecessary shares, so when AI agents query Microsoft 365, they operate on a clean, least-privilege data layer rather than years of accumulated access.
