Side-by-side comparison of AI visibility scores, market position, and capabilities
AI-native identity security platform governing human, non-human, and AI agent identities. Raised $50M Series B (Insight Partners, March 2026); $100M+ total raised; targets enterprise NHI sprawl and AI agent credential risks.
About
Linx Security is an AI-native identity security company that addresses one of the fastest-growing attack surfaces in enterprise security: the explosion of non-human identities (NHIs) and AI agent credentials that now outnumber human user accounts in most large organizations. Founded to tackle identity governance for the AI era, Linx recognizes that traditional Identity and Access Management (IAM) tools were designed around human employees and cannot effectively govern the service accounts, API keys, OAuth tokens, and AI agent identities that now permeate enterprise environments. A single misconfigured NHI can become an attacker's entry point to critical systems.\n\nLinx's platform provides unified visibility and governance across human identities, non-human identities, and AI agent credentials in a single control plane. It continuously discovers, classifies, and monitors identity relationships and access permissions across cloud environments, SaaS applications, and internal systems—surfacing misconfigurations, over-privileged accounts, and anomalous access patterns that traditional tools miss. As enterprises deploy autonomous AI agents that access APIs, databases, and sensitive systems, Linx's ability to govern AI agent identities with the same rigor as human identities becomes a critical security capability.\n\nIn 2026, Linx Security raised a $50M Series B led by Insight Partners, one of the most active investors in cybersecurity. This funding validates Linx's market thesis and provides capital to expand its platform capabilities and enterprise sales motion. The timing is significant: as AI agent deployments accelerate across enterprises, the NHI governance market is growing rapidly. Linx competes in the identity security space alongside established vendors like CyberArk and SailPoint, but its AI-native architecture and NHI-first focus give it a product advantage for the security challenges that matter most in 2025-2026.
Dallas TX enterprise browser platform; raised $490M+; secure Chromium-based browser giving IT full control over web application access and data flows.
About
Island Technology is an enterprise browser company founded in 2020 and headquartered in Dallas, Texas. The company was founded by Michael Fey and Dan Amiga to reimagine how enterprises secure access to web applications by moving security controls into the browser itself rather than relying on network perimeters that have become irrelevant in a cloud and remote-work era. Island built an enterprise browser based on the Chromium engine that is functionally identical to Google Chrome for end users but gives IT and security teams complete control over what data can be accessed, copied, printed, screenshotted, or uploaded within each web application.\n\nIsland raised $490 million across multiple funding rounds including a $250 million Series D, valuing the company above $3 billion. The platform addresses use cases across contractor and third-party access, BYOD environments where employees use personal devices to access corporate applications, and zero-trust access control for web-based SaaS applications. Because the enterprise browser sits directly in the data path between the user and every web application, it can enforce granular policies — for example, preventing a contractor from copying data from Salesforce while still allowing them to read it — without requiring VPNs, virtual desktops, or complex network configurations.\n\nIsland's browser also provides deep telemetry on user activity within web applications, enabling security teams to detect risky behavior, investigate incidents, and conduct phishing-resistant authentication. It integrates with major identity providers for SSO, with DLP platforms for data classification, and with SIEM tools for activity logging. The company has attracted customers in financial services, healthcare, legal, and technology sectors where sensitive data access by third parties and remote workers is a significant security challenge.
