Nightfall AI
AI-native DLP that controls how sensitive data moves across AI agents, MCP servers, endpoints and SaaS.
By Nightfall AI · 4.5/5 Value-Position score (estimate)
Positioning guardrails
Best for
- Security teams at 250–100,000+ user organisations replacing legacy DLP suites
- CISOs who must stop sensitive data flowing into ChatGPT, Gemini and other Shadow AI tools
- Companies that need to govern AI coding agents and MCP servers alongside SaaS and endpoint data movement
- Regulated teams needing PII, PHI, PCI and secret detection at a claimed 95% precision with little tuning
Ideal size: Security/compliance teams of 3–50 people · Mid-market to Fortune 500 with a CISO-led security programme
Not for
- Teams wanting a self-serve product with published per-seat list pricing
- Organisations that only need Microsoft 365 data protection, where Purview may already suffice
- Buyers looking for network-only or fully on-premises DLP with no endpoint or browser agent
- Small firms with no dedicated security or compliance owner to run and tune policy

Bottom line
Nightfall AI is an AI-native data loss prevention and insider-risk platform that controls how sensitive data moves across SaaS apps, email, macOS and Windows endpoints, browsers and AI agents. API integrations connect in minutes via OAuth and endpoint agents deploy through MDM, with pre-trained detectors claiming 95% precision out of the box. Premier adds AI agent and MCP server governance. Pricing is per user, per year and quote-based, with a free 7-day proof of value.
Frequently asked questions
How quickly can we deploy Nightfall and see value?
SaaS integrations are OAuth-based and typically live in under an hour; endpoint agents deploy fleet-wide via MDM (Jamf, Intune, Iru) in about 10 minutes across hundreds of users. Nightfall says pre-trained detectors surface violations within 24 hours and most customers reach coverage across SaaS, endpoints and AI tools in under a month. Typical proofs of value run two weeks, and there is a free 7-day proof of value including a security assessment report. No professional services are required.
How is Nightfall priced?
Pricing is per user, per year and quote-based; no list price is published. Two packages exist: Foundation Edition (DLP for SaaS, email, AI apps and endpoints) and Premier Edition, which adds AI agent and MCP security. Premier is quoted in two coverage tiers — up to 3 apps, or all supported apps. Every plan includes 150 GB of data-at-rest scanning, with 1 TB, 3 TB, 5 TB and 20 TB add-on packs. Each user licence includes 2 endpoint devices; extra devices are billed at the same per-endpoint annual rate. Contact sales for a quote.
What data can Nightfall detect, and where does it enforce policy?
Pre-trained detectors cover PII, PHI, PCI, API keys, secrets, credentials and source code, plus custom detectors for internal identifiers, at a claimed 95% precision. Enforcement runs across 12+ API-integrated SaaS apps (Google Drive, Gmail, Slack, Salesforce, Jira, Confluence, GitHub, Zendesk, Microsoft 365, Notion, ChatGPT Enterprise and more), email, macOS and Windows endpoints and browsers. Actions include block, redact, quarantine, delete, revoke permissions, encrypt, disable download and coach the user, tuned by user group, data class and destination.
Does Nightfall cover AI agents and MCP servers?
Premier Edition (Complete + AI Governance) adds hooks for Cursor, Claude Code and VS Code, scanning prompts, shell commands, MCP tool calls and tool responses, with LLM responses monitor-only. It discovers local (stdio) and remote (HTTP/SSE) MCP servers, scores shadow-MCP risk, enforces policy at an MCP gateway, and exports an OpenTelemetry audit trail plus Claude Compliance API monitoring for Claude Enterprise. Browser and endpoint agents block sensitive prompts, uploads and clipboard pastes into consumer AI tools such as ChatGPT, Gemini and Perplexity.
What compliance certifications and security controls does Nightfall hold?
Nightfall's security page states SOC 2 Type II certification and says the platform is commonly used for HIPAA compliance; its pricing FAQ also lists ISO 27001 certification and HIPAA-ready, GDPR-compliant status. Customers in financial services, healthcare, life sciences and the public sector use it for PCI DSS, HIPAA, GLBA and state privacy requirements. Data is hosted on AWS, GCP and Azure with encryption at rest and TLS/AES-256 in transit, annual third-party penetration testing and quarterly access reviews. Documentation is available under NDA.
How does Nightfall compare with Microsoft Purview or legacy DLP?
Nightfall positions itself as an AI-native replacement for legacy suites, citing 95% out-of-the-box accuracy versus 5–25% for pattern-matching tools, no regex tuning, and roughly 50x lower total cost of ownership than Forcepoint, Symantec or Proofpoint in customer reports. It says Purview is content-blind outside Microsoft 365, so teams often keep Purview for M365 and add Nightfall for Slack, Google Drive, GitHub, endpoints, browsers and AI tools. It also claims content-inspection depth beyond lineage-only tools such as Cyberhaven, and says customers consolidate 3–5 security tools.
