The Risk is Real and the Stakes are High

A single mislabelled document can lead to massive consequences. In one of the most significant breaches in recent years, a mishandled spreadsheet exposed PII of over 25,000 Afghan collaborators, leading to life-threatening consequences and political fallout.

Manual labelling processes, inconsistent policies, and overloaded systems create significant risk. DLP tools to prevent spill are only as good as the labels are accurate. At such massive scale, even the best trained workers often fail to classify their data accurately or keep pace with the variety and complexity of modern information estates.

Built for Compliance and Built to Scale

Castlepoint’s AI platform solves this by reading every item in the network, classifying content according to local and international policies, and applying the correct labels with complete transparency. The new Purview interface allows labels to be applied and enforced instantly within M365, supporting real-time policy enforcement without impacting users or performance.

Unlike machine learning or other closed-box models, Castlepoint’s AI uses a rules-based, explainable framework. This makes it fully compliant with government Ethical AI policies and privacy legislation, while providing audit-ready traceability of every decision.

Key Benefits

With this new integration, organisations can:

• Accurately classify and label content based on full-text analysis
• Classify based on organisation-specific risk, not just basic PII matches
• Push labels directly into Microsoft Purview for immediate enforcement
• Comply with privacy, records, security and AI governance requirements
• Detect and contain risk before it becomes a breach
