What Firezone does
Firezone is a Y Combinator-backed cybersecurity company that provides an open-source zero-trust network access (ZTNA) platform built on the WireGuard protocol. Founded in 2021 and headquartered in Mountain View, California, the company offers a VPN replacement that secures access to applications, services, and networks through simple, policy-based access controls. The platform is used by hundreds of organizations across cloud-first businesses, security-conscious enterprises, and hybrid infrastructure teams, with publicly named customers including Wolfram, NOMOBO, Corrdyn, Square1, TeraCloud, and Beakon.
Firezone's technology stack is built on WireGuard, which the company states delivers 3-4x the throughput of OpenVPN, with a data plane written in Rust and gateways deployed as lightweight Linux binaries. The platform supports NAT hole-punching to minimize attack surface, automatic load balancing and failover across multiple gateways, and identity provider integration with Google, Microsoft Entra ID, Okta, and any OIDC-compliant provider. Native client applications are available across macOS, Windows, Linux, Android, iOS, and ChromeOS, and the entire product is open-source for transparency and auditability.
The company operates a dual go-to-market motion combining product-led growth through a self-serve free tier (app.firezone.dev) with an enterprise sales motion for larger deployments. Revenue derives from subscription SaaS across Starter, Team, and Enterprise tiers, supplemented by self-hosted deployment options. Infrastructure spans three global regions (central US in Iowa, northern Europe in Ireland, and Australia East in Sydney) on Microsoft Azure, with billing and payment processing handled via Stripe. Firezone has achieved SOC 2 Type II certification, signaling enterprise-readiness despite a very small team of fewer than 10 employees.

Firezone competitors and assessment
Company assessmentDirect peers
- Tailscale: Closest direct competitor — also WireGuard-based zero-trust networking for teams. Customer quotes explicitly compare the two products head-to-head, making them near-substitutes in the ZTNA category.
- Twingate: VC-backed ZTNA startup offering a zero-trust alternative to traditional VPNs for distributed teams. Closely comparable in target customer (cloud-first businesses) and product positioning.
- OpenVPN: Legacy VPN vendor explicitly named by Firezone's customers as a solution replaced. Directly comparable on remote-access networking use case, though older protocol stack.
- NordLayer: Business VPN/ZTNA offering from Nord Security targeting SMBs and mid-market. Competes for similar cloud-first and security-conscious customer segments with comparable subscription pricing.
- Perimeter 81: ZTNA/SASE platform targeting SMB and mid-market — closely comparable customer segment to Firezone's horizontal SMB/mid-market focus. Competes for the same VPN-replacement budget.
Broad incumbents
- Cloudflare Zero Trust (Cloudflare Access): Cloud-delivered ZTNA/SASE suite from Cloudflare. Overlaps with Firezone on zero-trust access and identity-aware proxying but bundles a much broader networking and security portfolio.
- Zscaler Private Access (ZPA): Enterprise-grade ZTNA from Zscaler, a leader in the broader SASE market. Competes for the same VPN-replacement budgets but as part of a full security cloud platform.
- Palo Alto Prisma Access: Enterprise SASE/ZTNA offering from Palo Alto Networks. Targets the same VPN-replacement use case as Firezone but with full-stack security and significant enterprise sales coverage.
Emerging players
- NetBird: Open-source WireGuard-based overlay network for secure remote access. Highly comparable in technology stack and open-source positioning, though at an earlier maturity stage than Firezone.
- Nebula (overlay network): Open-source overlay networking tool from Slack, explicitly named in customer comparisons. Adjacent in functionality (peer-to-peer VPN) and competitive at the developer-segment edge.
