Bold Security vs SentinelOne
Side-by-side comparison of AI visibility scores, market position, and capabilities
AI endpoint security running ML models locally on devices; $40M raised (March 2026); reduces alerts 90%. Tel Aviv-based; founded 2024; Fortune 500 clients; edge-native architecture eliminates cloud latency for real-time threat response.
About
Bold Security is a Tel Aviv-based cybersecurity company founded in 2024 to reimagine endpoint protection using on-device AI. Rather than routing threat detection through cloud infrastructure, Bold's technology runs machine learning models locally on each device, enabling real-time threat response without latency or data exfiltration risks. This edge-native architecture is especially relevant for enterprises with strict data residency requirements or air-gapped environments.\n\nThe Bold platform targets enterprise security operations teams overwhelmed by alert fatigue. By running AI inference on-device, it filters and correlates endpoint signals before they reach the SOC, reducing alert volume by up to 90%. This dramatically cuts analyst workload and accelerates mean time to response. The company's Fortune 500 client base underscores its ability to meet the security, scalability, and integration demands of large organizations.\n\nFounded in 2024 and already serving Fortune 500 clients, Bold Security raised $40M in March 2026 — a significant financing round for a two-year-old company that reflects strong market pull for its on-device AI approach. As enterprises grapple with increasingly sophisticated endpoint threats and tighter privacy regulations, Bold's architecture offers a compelling alternative to cloud-dependent EDR platforms, positioning it as a fast-rising challenger in the $20B+ endpoint security market.
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.
