The Problem

Hidden Oversharing Doesn’t Stop After Deployment

You deployed Copilot. Oversharing is still exposing sensitive data.

Once GenAI tools like Copilot and Gemini are live, they continuously index and expose wGenAI tools index everything they can reach. Every day, they query your SharePoint, Teams, OneDrive, and Google Drive. Every day, they surface content that shouldn't be accessible. Without continuous monitoring, oversharing slips through. Years of prioritizing productivity, collaboration, and rapid information availability had naturally encouraged broad internal sharing practices across Microsoft 365 and Google workspace

AI Continues to Surface Overshared Data

Copilot and Gemini query your SharePoint, Teams, OneDrive, and Google Drive constantly. They find content that's been overshared for years. You have no visibility into what's exposed or who's seeing it.

Permission Drift

New files inherit bad settings. Someone shares a folder with "Everyone" because it's faster. These decisions compound into fresh exposure that AI tools will find.

Manual Monitoring Isn’t Scalable

Security teams can't review every permission change across terabytes of enterprise data. By the time you find oversharing manually, sensitive data has already been exposed.

The Solution

Continuous Protection for Secure AI Adoption

Opsin's Ongoing Oversharing Protection continuously detects and remediates oversharing so you stay secure long after deployment.

Track AI queries across Microsoft 365, Google Workspace, and other systems to spot sensitive data exposure as it happens.

Actionable Remediation Workflows

Receive prioritized, step-by-step guidance so site owners and teams fix oversharing quickly and correctly.

Root Cause Identification

Understand why data is overshared, not just where. Address permission and sharing issues at the source.

Decentralized Response

Empower business and site owners to remediate with automated notifications and workflows, maintaining centralized security control. Educate users on how to secure data in the AI era

Policy Enforcement & Alerts

Apply your AI governance policies and get alerts when oversharing patterns or risky AI behavior emerge.

How It Works

Ongoing Protection in 3 Steps

Continuous AI Monitoring

Opsin monitors AI queries across SharePoint, OneDrive, Teams, and Google Drive. When sensitive content surfaces, you see it immediately.

Prioritize & Alert

Automatically prioritize oversharing risks based on sensitivity and business impact, then send alerts and remediation instructions to the right teams.

Decentralized Remediation & Policy Enforcement

Site owners fix issues with step-by-step guidance. Security maintains oversight and enforces AI usage policies.

Customer Proof

Proven Results in Regulated Industries

Opsin’s Proactive Risk Assessment surfaced high-risk sites, libraries, and folders where CMMC-regulated information could be accessed by Copilot. Over 70% of Copilot-style queries returned sensitive data before remediation.

Frequently Asked Questions

Can Opsin enforce AI usage policies?

Yes — Opsin can map your internal AI governance policies into alerts and enforcement mechanisms tied to oversharing and risky AI behavior.

What does ongoing oversharing protection mean?

Opsin continuously detects when sensitive data is exposed through AI queries, prioritizes risks, and guides remediation so oversharing doesn't persist or resurface as your environment evolves.

What continuous protection covers:

  • Real-time monitoring tracks AI queries across Microsoft 365, Google Workspace, and other systems to spot sensitive data exposure as it happens
  • Root cause identification shows why data is overshared, not just where, so you can address permission issues at the source
  • Automated notifications alert the right teams when risky exposure patterns are detected
  • Decentralized remediation empowers site owners to fix issues while security maintains oversight

What is GenAI oversharing and why does it happen?

GenAI oversharing occurs when AI tools surface sensitive data to users who technically have permission to access it but were never intended to see it.

Common scenarios:

  • "Everyone Except External Users" permissions on sites containing PHI, financial data, or intellectual property
  • Inherited permissions that give organization-wide access to sensitive subfolders
  • Public channels where regulated information was shared assuming limited visibility
  • Legacy sharing links created years ago that remain active

GenAI tools don't create new vulnerabilities. They reveal existing permission issues by making content instantly discoverable through natural language queries.

How quickly can Opsin surface new oversharing incidents?

Opsin monitors AI interactions in real time and triggers alerts immediately when risky exposure patterns are detected.

Does Opsin fix oversharing automatically?

No. Opsin doesn't change content directly. Instead, it provides prioritized remediation steps and notifications so the right owners can fix issues at the source without overwhelming IT.

How decentralized remediation works:

  • Prioritized guidance tells site owners exactly what to fix and why it matters
  • Step-by-step instructions walk them through remediation quickly and correctly
  • Automated notifications reach the right people without manual routing
  • Security oversight maintains centralized control while distributing the workload

This approach educates users on how to secure data in the AI era while keeping remediation scalable.

Can Opsin enforce AI usage policies?

Yes. Opsin can map your internal AI governance policies into alerts and enforcement mechanisms tied to oversharing and risky AI behavior.

Policy enforcement capabilities:

  • Apply your governance policies to monitoring and alerting workflows
  • Get alerts when oversharing patterns or risky AI behavior emerge
  • Maintain compliance as teams continue sharing and collaborating
  • Track policy adherence across your AI deployment

Does Opsin work with Google Gemini and ChatGPT Enterprise?

Yes. Continuous oversharing protection covers Copilot, Google Gemini, ChatGPT Enterprise, and other AI tools that index your data.

Supported platforms:

  • Microsoft 365 Copilot across SharePoint, OneDrive, Teams, and connected data sources
  • Google Gemini with visibility into Google Drive and Google Workspace
  • ChatGPT Enterprise monitoring data shared with OpenAI
  • Enterprise search platforms that index multiple repositories

What is the difference between AI Readiness Assessment and Ongoing Oversharing Protection?

AI Readiness Assessment simulates what GenAI can access before rollout. Ongoing Oversharing Protection continuously monitors and stops oversharing as AI adoption scales.

When to use each:

  • AI Readiness Assessment: Before deployment. Opsin connects with one click and delivers your AI risk report in 24 hours showing which sites, folders, and files expose sensitive data.
  • Ongoing Oversharing Protection: After deployment. Opsin watches how GenAI tools interact with your data and identifies when sensitive or regulated content is surfaced through queries.

Get your AI Readiness Assessment before deployment.

Will Opsin continue to watch newly created files and sites?

Yes. Continuous coverage includes new content and changes to permissions over time, so fresh oversharing doesn't slip through.

How does Opsin connect to my environment?

Opsin uses a simple, API-based connection to Microsoft 365 (SharePoint, OneDrive, Teams) and Google Workspace. No agents or data movement required.

What Opsin accesses:

  • Permission structures showing who can access which sites, folders, and files
  • File metadata including file names, locations, and sharing settings
  • Sensitivity labels and classification information already applied to your content

What Opsin never accesses:

  • File contents or document text
  • Any data outside your Microsoft 365 or Google Workspace tenant

Can Opsin help maintain compliance after Copilot deployment?

Yes. Opsin helps organizations meet compliance requirements by continuously identifying where regulated data is overshared and could be exposed through AI tools.

Compliance use cases:

  • CMMC compliance for defense contractors protecting controlled unclassified information
  • HIPAA compliance for healthcare organizations preventing PHI exposure through Copilot queries
  • Financial services regulations securing PII and financial data to maintain regulatory compliance

Organizations in regulated industries use Opsin to ensure their Copilot deployment won't create compliance violations by exposing sensitive data to unauthorized users.
