Daylight

Daylight is a managed agentic security services company that provides AI-driven security operations for threat detection, triage, investigations, and response through a new operating model called Managed Agentic Security Services (MASS), where AI agents and senior security experts run security operations together. The platform addresses the limitations of traditional MDR, which cannot keep up with modern non-deterministic, AI-accelerated attacks that unfold across SaaS, cloud, and endpoints. Daylight's MASS architecture powers multiple services from a single foundation: Managed Detection and Response (MDR) with continuous monitoring and context-aware investigations; Threat Hunting with coordinated autonomous agents using IOC-based and hypothesis-based hunting; Phishing Investigation and Response that enriches alerts from email and identity platforms with identity and activity context; and Agentic DLP Investigation and Response for investigating data loss prevention alerts. The platform integrates with security tools in days rather than months, supports bi-directional actions including auto-closing resolved issues, runs detection rules across business tools like Slack, GitHub, and Notion, and uses a Security Data Lake to store all alerts and logs without requiring a SIEM. Daylight Knowledge continuously learns what normal looks like across users, devices, access patterns, and workflows, while ChatOps connects to Slack, Teams, or email for real-time identity verification. The company employs zero junior analysts and zero night shifts, instead using a global team of senior incident response and threat intelligence researchers with 10+ years average experience operating in a follow-the-sun model across four regions. Founded in 2024 and headquartered in Wilmington, United States, Daylight has raised $40M in Series A funding from investors including Bain Capital Ventures, mpl.vc, and Craft Ventures.
