Resolution

  • 3.2.0.213 sensor has been removed from the product; New version containing a fix will be uploaded once available

  • If you have installed or updated to 3.2.0.213 sensor and signature updates are an important feature in your organization, roll back to sensor 3.1 until a fix is available
  • If you choose to stay on 3.2.0.213, consider enabling Submit unknown binaries for analysis (Cloud Analysis) and Delay Execute for Cloud Scan​ policy settings; You can also manually trigger a one-time signature update in one of the following ways:
