AI Moves Your Data. Nightfall Controls It.

Control data movement across AI agents, MCP servers, endpoints, and SaaS—without slowing innovation. Nightfall gives you real-time visibility and control over how sensitive data moves — and prevents what shouldn't leave. Legacy data security can't see or stop this.

Why Now

AI Broke Legacy DLP. It Wasn't Built for This.

Legacy DLP wasn't designed for how your data moves today. What real customers tell us about where Legacy DLP fails:

1. AI apps became an exfiltration vector
2. AI agents move data without human action
3. The user is no longer in the loop
4. Data movement without meaning

One unified view of how data moves—and where to stop it.

Data Exfiltration Prevention

1. Shadow AI Prevention
   Employee uploads financial forecast to ChatGPT via browser > prompt blocked, user prompted for justification

2. Coverage across every user action
   Employee emails customer list to personal Gmail > blocked at upload

3. Data Lineage
   File downloaded from Google Drive, renamed, synced to personal Dropbox > full lineage reconstructed, exfiltration flagged

AI Agent Security

1. Hooks level Interception
   Coding agent reads proprietary codebase via GitHub MCP server, attempts to exfiltrate via local stdio MCP server > blocked.

2. Prompt Injection
   Indirect prompt injection via email triggers Claude agent tool calls > Nightfall's hooks intercept and block before execution.

3. Tool Call Governance
   AI agent tool call returns customer PII from Salesforce > response classified by Nightfall.

4. MCP visibility
   Unknown MCP servers discovered running locally across 12 endpoints > full inventory surfaced in the dashboard. Policy defined to block MCP servers.

Data Detection & Response

1. Real-Time Scanning
   API keys posted to a public Slack channel > auto-quarantined, owner notified.

2. Automated Remediation
   PHI in outbound Gmail to external recipient > blocked before delivery.

3. Employee Coaching
   Employee receives real-time violation alert > reviews context, submits business justification, admin approves.

Frequently Asked Questions

What is Nightfall, and how does its technology work?

Nightfall is the AI-native DLP platform that prevents sensitive data exposure and exfiltration across SaaS, endpoints, email, browsers, and AI apps. Our core consists of 100+ AI-based models, LLM-based file classifiers, and Computer Vision models that classify content with 95% accuracy - far surpassing legacy solutions stuck at 5-25%. We combine content inspection with AI-based data lineage tracking that traces information from source to destination, understanding risk based on context, not just content patterns.

Which problems does Nightfall solve better than legacy DLP?

Nightfall eliminates the three critical failures plaguing legacy DLP: detection blind spots, operational overload, and deployment friction. While legacy solutions rely on basic pattern matching with 5-25% accuracy and require months of tuning, Nightfall's AI-based detectors, LLM-based file classifiers, and Computer Vision models deliver 95% accuracy out-of-the-box.

How does Nightfall stop data leakage?

Nightfall combines AI-powered content classification with intelligent data lineage to stop data loss before it happens. Our platform continuously monitors data movement across SaaS apps, endpoints, email, browsers, and Shadow AI apps, classifying sensitive content including secrets & credentials, PHI, PCI, and PII with 95% precision.
