AI Moves Your Data.
Nightfall Controls It.
Control data movement across AI agents, MCP servers, endpoints, and SaaS, without slowing innovation.

AI Agents Changed
Data Security Forever
For years, data security assumed a person was moving the data. Now an agent can autonomously pull from Salesforce, query a database, read a local file, call an MCP tool, summarize the result, and send it somewhere else, all before a security team has a chance to ask what happened.
Legacy tools see pieces of the event. Nightfall sees the decision, and sits in front of it.
One Complete Platform for
Every Way Data Moves
Protect data across all systems, human and agent, and the investigations that connect them. Nightfall gives security teams one intelligent platform to discover risk, prevent exposure, and respond with context, across AI agents, MCP servers, endpoints, SaaS, and e-mail.
Control How AI and
Agents Move Data
- AI agent and MCP governance - approve the servers you need, block the rest by default, enforce policy on every tool call - catch instructions hidden in tool responses before they reach the model
- Prompt injection interception - detect and block malicious instructions hidden in prompts, files, and tool responses before they reach the model or hijack an agent
- Shadow AI prevention - stop corporate data leaving through personal ChatGPT, unmanaged copilots, and browser AI tools
Control How People
Move Data
- Exfiltration prevention with lineage - stop data leaving across every channel, with full traceability from origin to destination
- Discovery and classification - find sensitive data already exposed across your SaaS before it becomes an incident
- Real-time detection and response - catch and remediate risk as it happens, not after the fact
Turn Alerts Into Answers
- AI Data Intelligence: pre-trained ML detectors and LLM classifiers for secrets, code, and customer PII
- Dynamic Risk Scoring: AI-powered insider and agentic risk correlation across multi-hop activity
- Zero-Config & AI Copilot: Day-1 "no-policy" visibility, with AI copilots for recommendations and triage
- Full forensic context on every event: who, role, lineage, prior behavior
Where Legacy DLP Stops,
Nightfall Starts
Real-Time Prevention
Network DLP alerts at the perimeter. Legacy DLP monitors. DSPM scans data at rest. None of them intervene in real time on the device where the action is actually happening. Nightfall enforces inline, at the point of action, before data leaves.
Full-Stack Visibility
Local egress, unmanaged web, clipboard, USB, AI agent tool calls, local IDEs, these are all blind spots for network DLP, CASB, and AI gateways alike. They see traffic that crosses a proxy. Nightfall sees what's happening on the device and inside the agent, where most of this activity never touches a network boundary at all.
Zero-Tuning Deployment
Legacy DLP needs months of rule tuning before it's usable. DSPM needs 6+ months just to scan. File-Tracking DLP 2.0 creates enough friction to trigger IT tickets on its own. Nightfall's detection is pre-trained and deploys without a tuning cycle.
Hundreds of security teams run on Nightfall
From First Signal to Final Action.
Whether data is moved by a person, an AI application, or an autonomous agent, Nightfall brings the activity into one clear security story.
