New capabilities give security teams visibility and enforcement over MCP servers, coding agents, and AI-driven data movement - before it becomes a breach.
June 11, 2026 - Nightfall AI, the AI-native data security platform, today announced the Early Preview launch of AI Agent Security, extending real-time data loss prevention to AI agents, coding assistants, and MCP-connected workflows.
AI agents now move enterprise data at machine speed, often without a human in the loop. Legacy DLP was not built to see this traffic, let alone stop it. Nightfall closes that gap.
AI Agent Security gives SecOps teams:
- Full-stack visibility into MCP servers, tool calls, and agent activity across Cursor, Claude Code, and VS Code
- Inline enforcement that blocks risky prompts, tool calls, and shell commands before execution
- Unified policy across human and AI-driven data flows, using the same detectors for secrets, PII, PCI, PHI, and prompt injection
- Audit-ready logging via OpenTelemetry, capturing every session, tool call, and decision
AI Agent Security is available now in Early Preview. Learn more: https://www.nightfall.ai/products/mcp-security
