This comment sounds like a promo for Tailscale. It's actually a suggestion to Firezone to model after what Tailscale are getting right. We need competition in this space, but tooling non-SV businesses can leverage. Tailscale is pulling this off well.
Tailscale is building a remarkable moat at extraordinary pace: capabilities real commercial use needs, on pricing that doesn't penalize the security-minded startup.
One key difference with their platform is the recognition so often missed inside the HN bubble that most B2B and B2C are on M365 and Entra, not Google like 3 devs in a cafe. Tailscale seems to understand the difference, but rather than going "enterprise" brings the startup ways into the business context, letting a business be like a startup while still complying with "requirements" such as sound patterns for tying into legacy internal and third party systems and networks.
A related difference is emphasis on "everything as code" from config to policy, enabling gitops of course, but also easier integration and automation.
That said, Firezone's choice to let groups flow from IdP and map resources to groups, can be a competitive advantage, since the only thing better than everything as code is no-code, meaning, no moving parts. For instance, with Firezone, you can make systems automatically accessible to Microsoft Teams, team by team. Adding someone to a team or kicking them from a team, can give them access or remove their access. That's a massive security gain and overhead reduction.
But the biggest differentiation seems to be solving corner cases that come up in real world use and rolling those out faster than firms can come up the curve in their own Zero Trust implementation. Tailscale must have an excellent forward-deployed product sensing practice, to either discover or listen to these problems from commercial users then tackle them and get it rolled out for all customers. Their docs are also use-case focused and self-service empowering: https://tailscale.com/kb/1300/production-best-practices with a clear understanding of how devs spend their time https://tailscale.com/kb/1360/developer-tools and generally organized by the "Diataxis" systematic approach to technical documentation authoring: https://diataxis.fr/
Finally, contrary to popular practice here, Tailscale don't have predatory pricing for SSO, no “SSO tax”.
The $0 plan includes SSO. Even if you're a one person shop, there's no reason not to get SSO going for yourself, every future SaaS you integrate with, and every future onboarding/offboarding will thank you. Switching to this later is far more costly than adopting it early, and we should all be supporting one another to make SSO (or Oauth2+OIDC) the norm instead of an "Enterprise Call Us" pricing discriminator.
It's great to see Firezone including OIDC in the starter plan, as that brings most of what anyone needs from "SSO", without most of the headaches. And this benefits Firezone too, they can't leak user passwords.
"Zero Trust" (such a terrible name for a pattern that actually means "enable trust on everything that matters") is a big deal, and more focus on this space is huge. It's worth building in this ecosystem, and worth paying attention to what overachievers are getting right.
