The downloads referenced under the "Cybersecurity Early Access" category are made available to subscribers to mitigate time-critical issues but have not undergone formal quality and performance testing associated with official OpenText/Cybersecurity product releases. OpenText has a multi-stage Quality Assurance process. During Stage 1 we conduct a resource analysis, field mapping, ensure content level 1 functionality and analysis in our sandbox environment. Stage 2 is a complete validation including production validation. This package has cleared Stage 1 validation and therefore should be deployed with the appropriate pre-production validation. OpenText strongly recommends that any downloaded content is first checked and tested thoroughly in a non-production environment before committing to production. We welcome feedback and, should any content be shown to be faulty, detrimental or carry an incorrect claim of authorship, we shall endeavor to remove or correct such content as promptly as reasonably possible once notified and validated.
