Has anybody heard of Cloudflare for Teams or planning on using it? Currently in beta.


Seems to be a transparent proxy / VPN for your applications & devices, based on the home page proclamations


Some interesting stats they list


  • Cloudflare operates within 100 ms of 99% of Internet users in the developed world
  • 30 Tbps of network capacity
  • Threat data gathered from securing more than 20M web properties
  • 72B cyber threats blocked per day
  • Intel from 11M HTTP requests per second on average

Anybody got some more details? Any configuration required on your apps & code / devices? Surely you still need end point protection of your devices?

I haven't used Teams yet but I have been using Cloudflare Access for a few months now to access web apps that I'm hosting on my Docker server at home. Seems to work really well and you can use it for free. From what I was reading today, Cloudflare Access is one of the key components of the new Teams product.

The way it works is that you proxy requests to your web app through the Cloudflare network. They authenticate the requests on your behalf, prompting the users to authenticate with providers of your choice - e.g. Google, Github, Microsoft, etc. Once the user has been authenticated they can access your web app. The key configuration you need to make is that you need to ensure that only Cloudflare IPs can access your web app either through a firewall or configuration in your webserver, otherwise bad actors would be able to bypass the authentication from Cloudflare. Here's an example of one of my sites: You should get prompted by a Cloudflare Access screen (assuming I've done it correctly!)

Another use-case for Cloudflare Access is for example my Vacuum Cleaner.


I de-clouded it so it now just had a web interface. I've exposed this to the internet via a proxy however being an embedded device it doesn't have any auth. I don't want anyone just starting my vacuum cleaner randomly and also wanted an easy way to use it on the go on my phone. So, I've locked down my proxy to Cloudflare's IP address ranges and also configured mutual SSL and Cloudflare Access.


Now when I want to start my robotic vacuum cleaner I just navigate to the webpage, use Google Auth and I am in. No need to VPN, no need for mutual SSL keys, no basic authentication and no exposing my vacuum cleaner "directly" to the internet.


Sure, I can use a VPN but this way my partner can use it without having to VPN in, from any device including her work computer to start the vacuum cleaner or check on it.


Honestly, not bad for free.
