is there an alternative to Kolide Fleet that is out there?

There are other osquery fleet managers. E.x. https://github.com/mwielgoszewski/doorman

This is super helpful, thank you!

You can also write your own.

Hi @Zach Zeid! On the commercial side, we have a security analytics platform based on osquery here at Uptycs (we have our own channel if you have questions)- focused on deployments of any scale.

Kolide primarily develops a SaaS — https://k2.kolide.com
