Firezone

Firezone is a zero-trust network access (ZTNA) platform founded in 2021 by Jamil Bou Kheir and Jason Gong. The product originated as a WireGuard-based open-source project before evolving into a commercial offering. Its first commercial version (1.0) launched in April 2024, following the company's participation in Y Combinator's Winter 2022 batch and a subsequent seed funding round.

Firezone's platform is built on WireGuard, a modern VPN protocol known for its simplicity and performance. The product is designed to enable organizations to control and secure access to their internal resources and internet-connected systems using a zero-trust model — meaning access is granted on a per-identity, per-resource basis rather than through broad network-level trust.

The platform targets organizations seeking to replace or supplement traditional VPN infrastructure with a more granular access control approach. It has accumulated over 15,000 users and 130 releases as of the information available on its website, indicating an active development cycle and an established user base.

Firezone emphasizes open development, privacy, and transparency as core operating principles. The company states it collects only the minimum data necessary to operate its product and does not sell or share user data with third parties. Its codebase is publicly available on GitHub, reflecting a commitment to open-source development practices.

The company is backed by Y Combinator, 1984 Ventures, Uncorrelated Ventures, Helium-3 Ventures, Amino Capital, and Gaingels.
