From Detection to Quarantine: Fixing OneDrive Risks at Scale

You finally have visibility. Cyera shows you exactly where your data lives and what’s at risk. But when you’re staring down tens of thousands of sensitive OneDrive files that are sprawled across business units or exposed to the wrong people, visibility alone isn’t enough. The real challenge is remediation. And no team, no matter how well-staffed, can tackle that manually.

That’s why Cyera continues to build automated remediation into the platform, now with the ability to quarantine risky OneDrive files. It’s part of a broader initiative we call Actionability, turning insight into impact, without endless manual work.

Why Remediation Is So Hard

Security teams don’t lack alerts. They lack time. Once a sensitive file is flagged (say a spreadsheet with thousands of patient records or tax IDs) it still has to be investigated, validated, assigned to a data owner, and addressed. That workflow breaks at scale.

A senior manager in GRC and Cybersecurity put it simply: “Remediation is the hardest challenge for us to solve.”

Why? Because in systems like OneDrive, risk is atomized. Instead of a single misconfigured database, you’re dealing with thousands of individual objects: documents, PDFs & exports. The remediation task lists balloons instantly. Multiply that by multiple business units, and the backlog is nearly impossible to clear.

From Risk Identification to Risk Containment

With Cyera, you can automate file quarantining in OneDrive, changing the cycle completely. Now, when the platform identifies sensitive files that violate policy, such as PII or PHI shared externally, Cyera can automatically take action to quarantine those files.

Here’s how it works:

• Cyera scans OneDrive environments for sensitive data and policy violations.
• When a file is found that contains sensitive data and is exposed (e.g., shared externally or publicly), it’s flagged.
• If configured, Cyera can automatically quarantine the file, immediately restricting access to reduce risk.
• The file owner is notified and can review, approve, or remediate further depending on organizational policies.

No agents. No manual ticketing. Just faster containment of real risk.

Real Results: 98% Risk Reduction in Less Than Six Months

One healthcare company using Cyera projected that it would take over a year to manually remediate OneDrive files with sensitive data. The files included:

• Personal Health Information (PHI)
• Personally Identifiable Information (PII)
• Financial data subject to regulatory controls
  

Instead, with Cyera, they were able to automate quarantining of the affected files, delivering a 98% reduction in OneDrive data risk in less than six months.

That didn’t just reduce exposure; it freed up security teams to focus on strategic work instead of chasing down file owners one ticket at a time.

Why It Matters for CISOs and GRC Leaders

For CISOs and GRC teams, this isn’t just a feature, it’s an inflection point. It means:

• Faster remediation without overburdening existing teams
• Lower regulatory risk from public or unauthorized exposure
• Improved audit readiness with consistent, policy-driven actions
• Better cross-team alignment, since Cyera actions can trigger workflows in systems like ServiceNow or notify stakeholders directly

Most importantly, it proves that proactive security doesn’t have to come at the cost of operational sanity.

Building Toward a Fully Actionable Data Security Program

Automated OneDrive quarantine is just another piece in the puzzle. The vision is clear: visibility, classification, and risk scoring should lead directly to action. Whether that’s revoking access, notifying owners, quarantining files, or triggering downstream workflows, Cyera will continue expanding to help security teams actually close the loop on risk.

Because seeing the problem is step one. Fixing it automatically, reliably, and at scale is where real value gets delivered.
