The Open Cybersecurity Alliance OASIS Open Project was sunsetted on March 31, 2026. OCA has transitioned to a different, community-led format under the ownership and governance of OASIS Open. Please see here for further information on the new format and governance of the OCA Commmunity.
The Open Cybersecurity Alliance (OCA) Open Project is an OASIS Open Project fostering an open cybersecurity ecosystem, where products from all vendors and software publishers can freely exchange information, insights, analytics, and orchestrated response, via commonly developed code and tooling, using mutually agreed upon technologies, data standards, and procedures.
For more information on the OCA, see the project's website at https://opencybersecurityalliance.org.
