archTIS and Mattermost are pleased to announce a collaboration to deliver policy-enforced, data-centric security to secure operational collaboration for Defence Ministries, NATO Allies, and coalition partners worldwide. The collaboration combines Mattermost’s secure, mission-critical command-and-control surface with archTIS Trusted Data Integration (TDI) platform, to enable secure collaboration using dynamic policy orchestration via Attribute-Based Access Control (ABAC).

Most organizations can't answer three basic auditor questions simultaneously: where PII lives, who can access it, and how it's protected. One-off scans and manual classification go stale as data volumes grow. A repeatable, eight-step PII protection program from initial discovery through ongoing governance is what separates a defensible compliance posture from a snapshot that collapses under scrutiny.

Microsoft 365 DLP delivers real protection for regulated data in Exchange, SharePoint, Teams, and managed Windows endpoints, but only within that boundary. On-premises file servers, Linux endpoints, unmanaged devices, and non-Microsoft SaaS fall outside enforcement regardless of how policies are configured. Most security teams can't yet clearly distinguish the gaps that configuration fixes can address from those that require supplemental controls.

A relationship manager asks the firm's AI assistant to "summarize my top wealth clients by AUM and flag anyone with a pending transfer over $500K." The agent calls a CRM MCP server, then a core banking MCP server, then a market data MCP server, and returns a clean answer in twelve seconds. Names, balances, account numbers, pending wire details, all rendered in plain text inside the chat window. No file moved. No email left the network. No DLP channel triggered.

Higher education faces a unique challenge when it comes to managing sensitive data governance. Unlike a more centralized corporate environment, colleges and universities often operate across many semi-independent schools, departments, research groups, and administrative teams. Each may have its own systems, priorities, workflows, and level of security maturity. That structure is part of what makes higher education work. It supports research, academic flexibility, and departmental independence.

Employees are feeding sensitive data into AI tools at a pace most security teams did not anticipate. Source code goes into coding assistants. Customer records get pasted into ChatGPT to draft emails. Confidential contracts land in Gemini for summarization. According to Cyberhaven Labs research, 39.7% of the data employees share with AI tools is sensitive, and the volume is accelerating as AI adoption spreads from individual contributors to entire workflows.

The best data loss prevention (DLP) tools in 2026 are those that move beyond rigid, rule-based systems to incorporate AI-driven behavioral analytics. Leading solutions like Teramind (best for AI agent governance), Microsoft Purview (best for M365 ecosystems), and Zscaler (best for cloud-native protection) provide the real-time visibility needed to stop data breaches before they occur.
