Document Introduction

This report, based on the latest data from the F6S community in March 2025, systematically compiles information on 100 top U.S. cybersecurity companies and startups. It aims to provide researchers with a comprehensive panorama of the current U.S. cybersecurity industry ecosystem. Cybersecurity, as the 42nd most popular industry and market category, is undergoing rapid technological iteration and market segmentation internally. Its coverage extends from traditional infrastructure protection to cloud-native security, AI-driven threat detection, data privacy governance, supply chain risk management, and emerging cross-disciplinary fields such as cyber insurance and risk quantification.

The report begins with an industry overview, noting that over 1,120 U.S. cybersecurity companies are currently being tracked and highlighting the relevance of cybersecurity to broader market groups such as security, computer security, and privacy. Subsequently, the report presents key information in detailed company profiles, covering everything from industry giants to emerging innovators. This information includes not only fundamental data such as company location, founding date, and funding details (investors and amounts) but, more crucially, extracts each company's technological positioning, core product value proposition, and target market.

The analysis reveals that core technology sectors exhibit a trend of high specialization and convergence. In the cloud security domain, companies like Wiz and Lacework focus on providing full-stack visibility and risk management for multi-cloud and Kubernetes environments, while emerging forces like Upwind Security emphasize the core importance of "runtime security." The application of artificial intelligence and machine learning has permeated from threat detection (e.g., Deep Instinct, SparkCognition) to risk scoring (Safe Security), policy management (Velotix), and even automated compliance (Kobalt Labs), among other areas. As data regulations become increasingly stringent, dedicated data security and privacy platforms (e.g., Immuta, DataGrail, Relyance AI) and extended detection and response (XDR) solutions (e.g., Cynet) are gaining significant attention.

Simultaneously, the report also reveals in-depth defense solutions for specific critical infrastructure. For example, Claroty and Nozomi Networks focus on industrial control system (OT) and Internet of Things (IoT) security; Phosphorus Cybersecurity is dedicated to remediating firmware and credential vulnerabilities in IoT devices. The importance of identity and access management (IAM) and API security (e.g., Salt Security, Traceable) as cornerstones of modern application architecture continues to grow. Furthermore, a notable trend is the direct integration of cybersecurity with business risk management, manifested in the rise of cyber insurance providers like Cowbell Cyber and Coalition, as well as companies like CyberCube that specialize in data analytics for the insurance industry. Together, they are driving the development of "active insurance" and cyber risk quantification (CRQ) models.

This list compiles a wide range of technical solution providers, from Skyflow, which offers a zero-trust data vault, to Sepio, which focuses on hardware asset risk management; from Swimlane, which enables security automation, to Secret Network, which builds privacy networks using blockchain. The report's content is sourced from official company information or disclosures within the F6S community, providing readers with solid primary materials and an index foundation for understanding the technological frontiers, capital preferences, and competitive landscape of the U.S. cybersecurity industry.
