Nightfall Nyx is an autonomous data loss prevention (DLP) platform designed to automate the detection, investigation, and policy tuning of data security at enterprise scale. Unveiled on July 30, 2025, Nyx combines precision AI detection with agentic automation to identify insider threats, reduce alert fatigue, and shift security operations from reactive to proactive workflows. By integrating natural language interaction, Nyx enables security teams to investigate incidents and adjust policies through conversational prompts rather than manual rule-crafting, thereby accelerating response times and improving overall threat coverage.
At its core, Nyx employs an annotation-driven supervised learning system that delivers contextual risk scoring based on content type, file lineage, source and destination domains, and user behavior patterns. The platform embeds an AI “copilot” within its console to continuously tune detection policies, suppress low-risk activity, and maintain persistent memory of past investigations. This approach not only reduces false positive rates by up to 90% but also extends coverage across SaaS applications, endpoints, generative AI tools, and email, providing a unified DLP solution that scales with organizational growth.
