Data loss prevention for security teams governing data across AI, endpoints, SaaS, and email.
O que é Nightfall?
Nightfall is a data security and data loss prevention platform for controlling sensitive information across employee activity and AI-driven workflows. It combines discovery and classification, real-time prevention, and investigation context across SaaS applications, email, endpoints, browsers, AI applications, agents, and MCP servers. Security teams can use it to identify exposed data, enforce policies as data moves, and investigate incidents with information about the user, source, destination, and related activity. The platform also includes Nyx, an AI-powered DLP analyst embedded in the Nightfall Console for querying the environment and reviewing recommendations.
O que Nightfall pode fazer?
Real-time exfiltration prevention
Enforce data policies across monitored endpoints, browsers, SaaS, email, and AI activity, including at the point of action in supported agent sessions.
AI agent and MCP controls
Premier adds hooks for supported developer tools, MCP discovery and inventory, and policy enforcement for tool calls. Hooks can scan prompts, tool calls, responses, and shell commands; LLM model responses are monitor-only.
SaaS discovery and remediation
Data Discovery and Classification scans connected SaaS applications for exposed sensitive data and supports remediation, including addressing inappropriate sharing and access misconfigurations.
Contextual incident investigation
Alerts can include user, role, data origin, destination, and preceding activity. Nyx supports natural-language questions, incident summaries, pattern analysis, and recommended actions from within the Nightfall Console.
Deployment and response workflows
Connect a SaaS application or deploy the endpoint agent, then configure policies and response actions such as notifications and user self-remediation.

Apply controls to AI harnesses and MCP activity so security teams can inspect prompts, tool calls, and tool responses, discover MCP servers, and enforce policy on supported workflows.
“Find and remediate exposed SaaS data”
Scan connected SaaS environments for sensitive information that is already exposed or shared too broadly, then investigate and remediate the identified risk.
“Investigate a suspected data transfer”
Review an alert with its associated user, data origin, destination, and surrounding activity; use Nyx to summarize an incident, examine patterns, or consider recommended response actions.
