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 stops it.

One Complete Platform for
Every Way Data Moves
Control data across every system, 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 email.
Control How AI and
Agents Move Data
- MCP Gateway – approve the servers you need, block the rest by default, and enforce policy on every tool call.
- Inference Hooks – inspect and block prompts, tool calls and responses inside the live session, across Claude web, desktop, mobile, Cowork, Claude Code and Claude in Slack.
- 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
- Every alert arrives with who did it, their role, where the data came from, and what they did before.
- Risk is scored across multi-hop activity, so one event is read in the context of the ones around it.
- Visibility on day one with no policies written; Nyx recommends what to tune and triages what matters.
- Pre-trained detectors for secrets, source code and customer PII, with no rule-writing.
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
AI moves your data. Nightfall controls it.
Whether data is moved by a person, an AI application, or an autonomous agent, Nightfall brings the activity into one clear security story.
