We also run the secure access layer that connects our people to the internet and to internal services: Zscaler, Menlo Security, and Tailscale

Right now we're building a new hub-and-spoke network in Google Cloud and connecting it to the rest of the environment.

We're also building in-house tools that turn live network state into clear answers during incidents
