SentinelOne vs KnowBe4
Side-by-side comparison of AI visibility scores, market position, and capabilities
AI-powered endpoint security with $800M revenue; autonomous threat response and rollback on the Singularity Platform competing with CrowdStrike after CrowdStrike's 2024 global outage.
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.

About
KnowBe4 is a cybersecurity company headquartered in Tampa, Florida that operates the world's largest security awareness training and simulated phishing platform, serving over 65,000 organizations across 11 million users. Founded in 2010 by Stu Sjouwerman, the company was built on the thesis that the human element — employees who click phishing links, reuse passwords, and inadvertently install malware — represents the primary attack vector in the majority of successful breaches, and that continuous, measurable security awareness training combined with simulated phishing exercises is the most effective way to reduce this human risk. KnowBe4 went public in 2021 and was taken private by Vista Equity Partners in 2023 in a transaction valued at approximately $4.6 billion.
