About
Onyx Security is an Israeli AI agent security startup founded in 2024 to address the emerging attack surface created by enterprise AI agent deployments. As organizations deploy autonomous AI agents that can take actions, access data, and interact with external services, Onyx identified a critical security gap: existing enterprise security tools were built for human users and traditional software, not for AI agents that operate autonomously and can be manipulated through prompt injection, model compromise, or tool misuse. Onyx was founded to build the security infrastructure layer that makes enterprise AI agents safe to deploy at scale.\n\nOnyx's platform monitors, governs, and protects enterprise AI agent deployments in real time — detecting anomalous agent behavior, enforcing least-privilege access policies, preventing prompt injection attacks, and providing audit trails for agent actions. The product is designed for Fortune 500 enterprises deploying AI agents in business-critical workflows where a compromised or misbehaving agent could exfiltrate data, take unauthorized actions, or cause operational harm. Onyx integrates with leading agentic AI platforms and enterprise security infrastructure without requiring architectural changes to existing agent deployments.\n\nOnyx Security raised $40 million in March 2026 and counts Fortune 500 companies among its early customers — a remarkable milestone for a company less than two years old. The funding and customer traction validate both the urgency of the AI agent security problem and Onyx's technical approach. The company is positioned to lead the AI agent security category as enterprise agentic deployments accelerate globally and CISOs begin to demand purpose-built security controls for AI systems operating in production environments.

About
CrowdStrike is an AI-native cybersecurity company founded in 2011 by George Kurtz, Dmitri Alperovitch, and Gregg Marston and headquartered in Austin, Texas, that built the endpoint detection and response (EDR) category and has since expanded into the broadest cloud-native cybersecurity platform in the industry. The company was founded on the insight that traditional antivirus software — signature-based, retrospective, and endpoint-isolated — could not keep pace with sophisticated adversaries operating at machine speed. CrowdStrike's founding architecture, the Falcon platform, was designed cloud-native from day one: a single lightweight agent on the endpoint feeding a cloud-based AI that learns from trillions of security events across every customer simultaneously. The company trades on Nasdaq under the ticker CRWD.\n\nThe CrowdStrike Falcon platform consolidates more than 28 security modules across endpoint security, identity threat protection, cloud security, next-gen SIEM and log management, threat intelligence, and managed detection and response — all delivered through a single agent and unified console. The AI at the platform's core, Charlotte AI, provides conversational security operations, automated investigation, and AI-generated threat summaries that reduce analyst workload. CrowdStrike's threat intelligence team, Adversary Intelligence, tracks and names nation-state and criminal threat actors globally, giving customers predictive insight into campaigns before they hit their environments.\n\nCrowdStrike reported $3.95 billion in annual recurring revenue (ARR) for FY2025 and total revenue of $3.74 billion, up 29% year over year, with a market capitalization of approximately $85 billion. The company has 8,600+ employees and counts a substantial share of the Fortune 500 and global governments as customers. Despite the July 2024 sensor update incident that caused a significant IT outage affecting millions of Windows systems globally, CrowdStrike's customer retention remained strong — a testament to the platform's depth of integration and the switching costs built into its consolidated architecture.
