Stop Data Exfiltration Anywhere

Stop sensitive data before it leaves

Browser uploads, AI prompts, personal cloud sync, USB, email, unauthorized SaaS. Nightfall traces data flows, blocks risky actions, coaches employees in real time, and now investigates the people behind the patterns, without owning the device.

The Problem

Endpoint DLP and insider-risk tools fail in the modern workplace

Built for a different era, legacy endpoint DLP and IRM tools inundate SecOps with false positives, leave coverage gaps, frustrate employees, and are a nightmare to maintain.

GAP 01

Blind to AI apps

Legacy DLP can’t see what employees paste into ChatGPT or upload to generative AI platforms, the fastest-growing exfiltration channel.

GAP 02

Incomplete evidence

Investigations mean piecing together partial logs. No session replay, no file preview, no lineage back to the document’s origin, and no view of the user over time.

GAP 03

Noise, not signal

80–95% of alerts go nowhere. Security teams burn limited hours on legitimate work flagged as exfiltration, while the real pattern hides in the queue.

Customer quote

“Nightfall gently redirects our people to the safe gen AI sites and blocks attempts to put PII or customer data into ChatGPT.”

How It Works

Every channel. Every action. Full context.

Lightweight agents and browser plugins monitor every vector, block risky behavior in real time, and capture complete evidence. Then User Risk Agents read the pattern across people, not just events.

Coverage across every exfiltration vector

Browser uploads, AI prompts, personal cloud sync, USB transfers, unauthorized SaaS, and personal code repos, across macOS, Windows, Chrome, Firefox, Safari, and Edge. No network changes required.
  • Captures prompts, copy/paste, and file uploads into AI tools
  • Context-aware AI classification of customer records, financials, source code, and confidential documents
  • Detects obfuscated content, images, and screenshots that pattern-matching DLP misses

Trace

Forensic session replay and AI-powered data lineage

When incidents occur, Nightfall provides instant clarity. See exactly how data was accessed, copied, and transferred, and trace each document from corporate origin to external destination.
  • Screen recordings for compliance reviews and insider investigations
  • Lineage across download, rename, compress, and exfiltration
  • File preview reveals the exposed content itself

03
Act

Real-time block, redact, or coach

Turn violations into teachable moments. Contextual notifications on endpoint, Slack, Teams, or email build long-term awareness while reducing adversarial enforcement.
  • In-browser coaching: “Use ChatGPT Enterprise for corporate data”
  • Specialized protection for code repositories, secrets, and development artifacts
  • Block the action, redact the sensitive fields, or redirect to the approved path

Investigate

Nyx investigates, tunes, and reports

Your agentic DLP analyst. Nyx investigates incidents, tunes policies, and surfaces risk insights autonomously, with the full story attached instead of a flag.
  • Ask in natural language, get summaries and recommendations
  • Visibility on day one with no policies written
  • Pre-trained detectors for secrets, source code, and customer PII

USER RISK AGENTS
Early Access

User Risk Agents surface the person behind the pattern

Beyond blocking individual movements: Triage scores every employee against their own history and company norms. Investigator reconstructs the timeline and tests alternative explanations. A verifier challenges weak findings. The result is a written case, not another alert.
  • Suspicious intent rated separately from risky habits
  • Whose data, which destination, unusual for whom: the details that change the conclusion
  • Escalate or resolve from the case; routed to Email, Slack, Teams, Jira, SIEM/SOAR; nothing sent to the employee

User Risk Agents
NEW
Early Access

Blocking the file is step one. Knowing the person is the answer.

User Risk Agents connect employee activity, sensitive content, and identity over time. A Triage agent scores every user against their own history and company norms. An Investigator reconstructs the timeline, inspects content, and tests alternative explanations. An evidence verifier challenges weak findings before anything is published.

The output is a written case: what happened, why it matters, what to do next, with suspicious intent rated separately from risky habits. Nothing is sent to the employee.
