Zulu Enterprise Data Sheet

Stay current with quarterly updates

Zulu Enterprise includes the latest advances in OpenJDK provided by its vibrant open source community. Today Zulu Enterprise subscribers have access to Flight Recorder, Zulu Mission Control, and the latest Transport Layer Security (TLS 1.3).

Plus, unlike all free OpenJDK builds, Zulu Enterprise subscribers get quarterly access to CPU updates (containing critical security fixes only) and PSU updates (including security patches, bug fixes, and new features), enabling OPS teams to deploy critical security updates immediately and add less-critical updates later.
