## Company Overview

Tenex is an AI-native managed detection and response (MDR) company founded to rebuild cybersecurity operations using AI, addressing the failure mode of legacy SOCs overwhelmed by alert volume and constrained by analyst shortages. The company was built on the conviction that effective enterprise threat response requires a platform where AI performs first-line triage, investigation, and containment — compressing response times from hours to minutes. Tenex's core technology applies AI agents to continuous threat hunting, behavioral anomaly detection, and automated incident response.\n\nTenex operates as a fully managed service: customers receive 24/7 threat monitoring and response without staffing an internal SOC. Its AI platform ingests telemetry from endpoints, networks, cloud environments, and identity systems, correlating signals across the full attack surface. Operating at lower cost per protected endpoint than analyst-heavy MDR providers, Tenex makes enterprise-grade security accessible to a broader set of organizations and serves Fortune 500 clients across financial services, healthcare, and critical infrastructure.\n\nTenex reached unicorn status, raised $250 million in a Series B in March 2026, and was ranked the number-one fastest-growing cybersecurity company by IT-Harvest. It competes with CrowdStrike Falcon Complete, Arctic Wolf, and Secureworks, differentiating through AI autonomy in response workflows and the ability to deliver SOC-level outcomes without scaling analyst headcount. As threat timelines compress and talent shortages deepen, AI-native MDR is among the most urgent infrastructure investments in enterprise security.
