What Nightfall does
Nightfall (legal entity Nightfall AI) is a San Francisco-based, privately held company founded in 2018 that operates an AI-native Data Loss Prevention (DLP) platform designed to detect and prevent sensitive data exposure across SaaS applications, endpoints, browsers, and AI tools. The platform is built on more than 100 proprietary AI-based models, including LLM-powered file classifiers covering 22+ document types and Computer Vision models, with claimed 95% detection precision versus 5-25% for legacy regex-based DLP solutions. The product portfolio comprises three core products (Data Exfiltration Prevention, Data Detection & Response, Data Discovery & Classification) and two add-on modules (Nyx, an autonomous agentic DLP analyst, and MCP & AI Agent Security for Model Context Protocol governance), supported by AI File Classifier Detectors, browser plugins across all major browsers, and lightweight endpoint agents for macOS and Windows. The platform integrates natively with 30+ enterprise systems including Slack, Microsoft 365, Google Workspace, Salesforce, GitHub, Atlassian, Zendesk, Notion, and identity providers (Okta, Entra ID, Google Directory, Auth0), with SOC 2 Type II certification and HIPAA, PCI DSS, and GDPR alignment.
Nightfall's go-to-market is enterprise-focused with a quote-based SaaS subscription model sold on annual contracts, combining direct enterprise sales with API-first frictionless deployment (claimed under-1-hour setup). The company targets security decision-makers across Technology, Healthcare, Financial Services, Legal, and Manufacturing verticals with named customers including Snyk, Genesys, Telnyx, Cox Communications, Aarons, UserTesting, Reltio, Bitso, Nova Credit, and Unit21. Distribution leverages a mix of content marketing, G2 social proof, ROI calculators, case studies, and direct sales; a certified Slack Marketplace listing extends reach through app-store channels.
The company has raised approximately $72 million in total venture funding, anchored by WestBridge Capital across a $40 million Series B in August 2022 and a $32 million follow-on in February 2026, with earlier participation from Bain Capital Ventures, Venrock, Pear VC, Next Play Capital, and Webb Investment Network. Headcount is reported at 101-250 employees. The leadership team is co-founded by Rohan Sathe and Isaac Madan (co-founders and CEOs), with Brandi Moore as COO and Bernard Koh as CFO.

Nightfall product offering
Product offeringCore offering
Nightfall provides an AI-native Data Loss Prevention (DLP) platform that uses machine learning, large language models (LLMs), and computer vision to identify, classify, and protect sensitive data (PII, PHI, PCI, secrets, source code) across SaaS applications, endpoints, browsers, and AI applications. The platform prevents data exfiltration in real time through API-based integrations, browser plugins, and endpoint agents, replacing legacy regex-based DLP tools with 95% detection precision.
Product overview
Nightfall is an AI-native Data Loss Prevention (DLP) platform that provides a unified suite of products for preventing sensitive data exposure and exfiltration across SaaS applications, endpoints, browsers, and AI tools. The platform consists of four core products: Data Exfiltration Prevention (DEX) for preventing data from leaving the organization, Data Detection & Response (DDR) for real-time monitoring of SaaS environments, and Data Discovery & Classification for finding and remediating sensitive data across applications. Two add-on modules extend the platform: Nyx - Autonomous DLP Analyst provides agentic AI that autonomously investigates incidents and tunes policies, while MCP & AI Agent Security provides enterprise security for Model Context Protocol and AI agentic workflows. The platform is powered by 100+ AI-based models including LLM-based file classifiers and Computer Vision models that deliver 95% accuracy out-of-the-box. Key features include AI File Classifier Detectors for unstructured document protection, browser plugins for real-time AI app monitoring, and lightweight endpoint agents for comprehensive coverage without disrupting productivity.

Nightfall competitors and assessment
Company assessmentBroad incumbents
- Palo Alto Networks (Cortex XSIAM / Enterprise DLP): Broad cybersecurity platform with DLP integrated into Cortex and Prisma offerings. Competes for the same enterprise security wallet, though DLP is a secondary capability within a broader platform play.
- Forcepoint: Legacy DLP vendor with broad on-prem and cloud data protection coverage. Nightfall explicitly positions against Forcepoint, claiming 95% detection precision versus 5-25% for legacy solutions like Forcepoint.
- Microsoft Purview: Microsoft's broad data governance and DLP suite bundled into Microsoft 365 E3/E5 licenses. Serves as the default incumbent DLP for enterprises standardized on Microsoft 365, competing with Nightfall for IT budget allocation.
- Symantec DLP (Broadcom): Legacy enterprise DLP platform now under Broadcom, used as the classic benchmark for legacy 6+ month deployments. Nightfall consistently contrasts its API-first speed against Symantec's heavy implementation profile.
Direct peers
- Proofpoint: Enterprise DLP and email security vendor with overlapping coverage on email, cloud, and endpoint data channels. Competes with Nightfall especially in regulated industries requiring HIPAA, PCI, and SEC compliance reporting.
- Netskope: Cloud-native security platform with strong DLP capabilities across SaaS, IaaS, and web traffic. Directly comparable to Nightfall in targeting enterprise customers seeking modern, API-driven data protection versus legacy endpoint DLP.
- Zscaler: Cloud security platform offering inline DLP as part of its Zero Trust Exchange. Targets similar enterprise buyers and competes with Nightfall for SaaS and AI-app data protection budgets, though at much larger scale.
Emerging players
- Cyera: AI-native data security posture management (DSPM) company focused on cloud data discovery and classification. Most direct emerging competitor to Nightfall's Data Discovery & Classification product with similar AI-native architecture.
- Polymer DLP: AI-native data loss prevention platform that competes head-to-head with Nightfall in the SaaS and AI-app DLP category. Direct emerging peer in the modern, API-first DLP segment.
- Strac: Browser-based DLP vendor detecting sensitive data across SaaS apps, AI tools (including ChatGPT), and endpoints. Closest direct competitor on browser-plugin interception of AI prompts and uploads.
