The underlying data collection approach is similar however, our focus in application performance monitoring for developers and Sysdig's focus is on container level security & monitoring for devops,devsecops (@Sysdig folks please correct me if I am wrong :) )

Sysdig was a pioneer in harvesting data from the kernel. Their original solution required installing a kernel module and they are now moving to eBPF based approaches. The Falco project is really exciting.

Since we're a relatively new project (started 2 years ago) we started with eBPF and built our platform around it. As we open source we'll share with groups like Falco and hopefully collaborate.
