Duo Beyond was a very smart move on their part, taking Google's enterprise security architecture and turning it into a third-party turnkey solution for enterprise customers. They did it before Cloudflare, too. I bet that is a big part of the reason why Cisco is paying so much now.

There isn't anything particularly innovative about Duo Beyond. Inspect the Docker containers and you'll see they simply rebranded simplesamlphp and wrote a custom ngx_http_auth_request_module handler for NGINX for their authenticated reverse proxy product.

If Cisco paid 2 billion dollars for this, my mind is really blown. I'm struggling to figure out how they ended up at 2 billion because I don't see it in anything material -- perhaps the patents or a play against Okta for recurring revenue from smaller companies which might not have Cisco gear?

Cisco didnt pay $2B for simplesamlphp, they paid it for "Duo Security provides cloud-based tools to prevent security breaches on devices." :)
