Unlike industry-specific platforms for sharing threat data, OCA is uniquely focused on product interoperability, with benefits for the entire cybersecurity community:

Security Vendors can:

  • Increase integration exposure and reduce engineering
  • Leverage open source connectors and add value to your products
  • Deliver more robust data integrations
  • Allow clients to extract more value from your tools

Security Practitioners can:

  • Share information, analytics, and orchestrated response between products
  • Discover critical insights and findings you’re missing now
  • Avoid buying unnecessary tools
  • Free yourself from vendor lock-in

OCA Sub-Projects and Working Groups

OCA advances a growing body of open source projects and working groups.


An OASIS Open Project, OCA operates under an inclusive, fair process that assures secure licensing and a path for recognition in international policy and procurement.



Our goal is interoperability across cybersecurity products. We’re not another data sharing platform.
