How Open Source Companies Build a Security Business
from The Open Source Business with Fexingo: Commercial Strategy for Free Software Companies · host Fexingo
Open source companies are increasingly building security products on top of their core platforms, turning a community liability into a revenue driver. In this episode, Lucas and Luna examine the specific playbook used by Elastic and its Elastic Security product. They break down how Elastic layered SIEM and endpoint detection on top of the Elasticsearch stack, how it priced and positioned security as a commercial add-on without alienating the open source community, and what the results have been — including the key metric: security now accounts for over 30% of Elastic's total revenue. Along the way, they explore the tension between open source transparency and security product secrecy, and why this model works best for infrastructure tools that already handle sensitive data. The hosts also tie the discussion to listener support, noting that conversations like this are possible because of direct audience contributions at buy me a coffee dot com slash fexingo.
