About
Shift5 is an Arlington, VA-based cybersecurity and operational intelligence company that focuses on the onboard operational technology (OT) data bus found in aircraft, military vehicles, rail systems, and maritime vessels. Unlike IT-focused security companies, Shift5 captures and analyzes the raw data streams running on physical platform bus systems (such as MIL-STD-1553, ARINC 429, and CAN bus) to detect anomalies, enable predictive maintenance, and protect against cyber threats — all without disrupting the real-time operation of the platform.
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.
