Microsoft issued a stark warning this week: threat actors are actively exploiting a zero-day vulnerability in on-premises SharePoint servers to gain access to sensitive government and business data. The company confirmed the attackers are spoofing authentication tokens, escalating privileges, and moving laterally through compromised networks—all before defenders even know a breach occurred.
For organizations that rely on SharePoint to collaborate across teams and store sensitive files, this alert should prompt an immediate question:
If attackers breached your environment today, would they find a goldmine of exposed data—or a well-governed, locked-down estate?
The Real Risk: What’s Sitting on Your Servers?
Even the most hardened perimeter security can’t account for what’s already inside the walls: sprawling, unsecured unstructured data—emails, files, contracts, IP, customer information, and more. In a SharePoint environment, these documents often live in misconfigured folders with inherited permissions, excessive access rights, and zero classification.
This is where Data Security Posture Management (DSPM) becomes essential.
How Congruity360 DSPM Protects SharePoint and Beyond
At Congruity360, we help organizations take control of unstructured data risk by making sensitive content visible, governed, and defensible. Here’s how our DSPM solution helps protect environments like SharePoint from the inside out:
Discover and Classify Sensitive Content: Our platform continuously scans your SharePoint repositories and connected data stores to identify files containing PII, PHI, financial data, credentials, and IP. Each file is classified based on content, metadata, and regulatory relevance (GDPR, HIPAA, CCPA, etc.).
Enforce Policy at the File Level: Once classified, we apply policy-driven actions to each asset—encrypt, quarantine, redact, retain, or delete. This file-level control helps enforce least-privilege access and reduces the likelihood of exfiltration in the event of a breach.
Support Incident Response and Audit Readiness: In the event of compromise, detailed audit logs and data maps allow security teams to rapidly understand what data was exposed and to whom. This speeds up incident response, supports reporting to agencies like CISA or the FBI, and satisfies regulators demanding proof of data governance controls.
Shrink Your Attack Surface: By identifying redundant, outdated, and trivial files (ROT), our platform helps organizations de-risk their data estate. Less data means less to protect—and less for attackers to steal.
From Reactive to Resilient
The Microsoft SharePoint alert is a reminder that even industry-standard platforms can be vulnerable. DSPM bridges the gap between infrastructure and information—ensuring your data is protected even when systems are compromised.
If you’re storing sensitive data in SharePoint, Teams, or other unstructured environments, the time to act is now. Congruity360’s DSPM platform can help you gain visibility, control, and peace of mind.
