Gathering Diagnostics

Once you have logged a support case, further diagnostic files may be required to troubleshoot the problem you have described.

If you would like to provide us with additional information or files up front when you log a case, this may help to speed up the analysis. We have compiled a guide outlining which information is most useful when investigating the different kinds of problems. Please note, that this is intended only as a guide and you may be asked by the Security Analyst to provide further information to assist them with the problem analysis during the case lifecycle.

The Diagnostics Gathering guide is accessible via the SecureCall portal.
