Has grown a WireGuard-based open-source Zero Trust platform from a side project to thousands of companies within about four years.
Provides secure, cost-effective private networking that MSPs and enterprises can audit and self-host, reducing both cost and vendor-trust friction.
Closed a $10M Series A in January 2026 led by Pace Capital, with Nauta Capital and InReach Ventures participating.
Open-source, auditable Zero Trust networking is a genuine alternative model to closed-source SSL VPN incumbents, though open-source VPN/Zero Trust tooling is not itself new.
Broad open-source adoption (thousands of companies via GitHub) is a reasonable usage signal, though no independent security-efficacy testing was found.
Zero Trust network access remains a durable, growing priority as organizations move away from legacy perimeter VPNs.
Why CISOs Should Care
Gives security teams an open-source, WireGuard-based Zero Trust network platform as a transparent, auditable alternative to proprietary SSL VPN products, with product-led adoption that lets teams start securing connectivity without a lengthy procurement cycle.
What Makes It Different
Built and distributed as open source from day one, letting security and engineering teams audit the code directly, versus the closed-source model used by incumbents like Fortinet and Sophos.
The Matrix Verdict

Editorial Note: Claims vs. Verified Findings
Founding year has minor discrepancies across sources (2021 GitHub launch vs. 2022 company formation); customer names (Sport Alliance, netgo, Signicat) are vendor-cited and not independently verified.
