I appreciate the response - great blog post. I don't doubt this works for certain companies and components of the ecosystem; it worked for Dropbox (at least for a long time).

Tailscale is clearly a superior product to it's competitors and I have regularly recommended colleagues and clients to evaluate whether it fits their needs. However, unfortunately, that is frequently not enough to "win" in the crowded and bureaucratic enterprise software space.

I would love to be proved wrong here and wish you the greatest success!

The big problem with Tailscale in enterprise is it can't touch anything that interacts with lots of compliance domains, which typically require FIPS.

There are creative ways to get around that, but it makes implementation a complex story and heavy lift.

Of course the typical comment that ignores every other country except the USA.

Which "compliance domains" are you thinking of that require FIPS crypto for access VPNs? Be specific, if you can? Thanks!

Say you were a county social services department. You wish to use Tailscale to microsegment federal tax data (subject to IRS 1075 safeguards requirements) relating to your child support unit from other traffic (say Medicaid enrollment) which does not have that requirement.

I’m pretty confident that you would draw an audit finding for that reason with a pure tailscale solution. (I also think that’s bullshit.)

1075 does not appear to require that access VPNs use FIPS cryptography. Arguably, it would if you were relying exclusively on WireGuard for data protection, but it's uncommon for people to do that (we're WireGuard true believers and we do in places depend on WireGuard authentication and encryption for our security model, but it's a weird enough thing to do that we notice it when we do it).

See section 4.18, control SC-13.

[tptacek]

Yes, I'm familiar. I don't believe that means everything you use that happens to involve cryptography has to comply with that control.

Too many ChatGPT interactions lately, I suspect.
