WireGuard-based Zero Trust VPN replacement with peer-to-peer connections 3-4x faster than traditional VPN; $1M ARR with 7-person team competing with Tailscale and Cloudflare Access.
About
Firezone is a Zero Trust Network Access (ZTNA) and VPN replacement platform built on WireGuard — providing fast, secure remote access that's 3-4x faster than traditional VPNs through encrypted peer-to-peer connections with NAT traversal (holepunching) technology, automatic failover, and identity-based access control. Founded in 2021 and backed by Y Combinator, Firezone raised $2.91 million, reaching $1 million in revenue in 2024 with a 7-person team and launching Firezone v1.0 after 200%+ active user base growth in 2023.\n\nFirezone's architecture uses WireGuard's state-of-the-art VPN protocol (fast, secure, minimal attack surface) with a management layer that handles the enterprise requirements: SSO integration with Okta, Azure AD, and Google Workspace for identity-based access policies, automated certificate management, split tunneling for selective routing, and the holepunching technology that enables direct encrypted connections between clients and resources without traffic routing through central servers (eliminating the bandwidth bottleneck of hub-and-spoke VPN architectures).\n\nIn 2025, Firezone competes in the ZTNA and secure remote access market with Cloudflare Access, Tailscale (the most popular WireGuard-based mesh VPN), and traditional enterprise VPN vendors (Cisco AnyConnect, Palo Alto GlobalProtect) for enterprise remote access. The ZTNA market has grown as security teams recognize that traditional VPN architectures (where authenticated users get broad network access) don't align with Zero Trust security principles that assume breach and minimize lateral movement. Firezone's open-source version builds developer adoption and trust, while the commercial version provides enterprise management and support. The 2025 strategy focuses on growing enterprise deployments, deepening access policy granularity, and positioning as the cost-effective alternative to premium ZTNA products.
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.
