About
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.

About
SentinelOne is a cybersecurity company providing AI-powered endpoint detection and response (EDR), extended detection and response (XDR), cloud security, and identity security through its Singularity Platform — using machine learning to detect and autonomously respond to malware, ransomware, and advanced threats in real time without requiring human intervention. Listed on NYSE (NYSE: S) and headquartered in Mountain View, California, SentinelOne generates approximately $800 million in annual revenue and competes with CrowdStrike for the enterprise endpoint security market.\n\nSentinelOne's Singularity Platform differentiates through autonomous response capability — when a threat is detected, the platform can automatically isolate infected machines, terminate malicious processes, roll back files to pre-attack states, and remediate damage without requiring a security analyst to approve each action. This "autonomous" response model reduces the threat dwell time and damage from fast-moving ransomware attacks that can encrypt thousands of files in minutes. The cloud-native architecture uses the Singularity Data Lake to correlate telemetry across endpoints, cloud workloads, and identities for unified threat detection.\n\nIn 2025, SentinelOne competes primarily with CrowdStrike Falcon for enterprise EDR/XDR market share — the two companies have become the dominant modern endpoint security vendors, having displaced legacy antivirus from McAfee and Symantec. The July 2024 CrowdStrike Falcon content update outage (which caused millions of Windows machines to crash) created a significant opportunity for SentinelOne, which accelerated customer acquisition in the months following. SentinelOne's 2025 strategy focuses on growing Purple AI (its generative AI security analyst that provides natural language threat investigation), expanding cloud workload protection, and growing identity security through its Singularity Identity product.
