The old parser cef-latest is deprecated, and replaced by the new parser claroty-ctd . While the old parser will remain available during a tranisition period, all future changes will only go into the new claroty-ctd parser. We recommend switching to the newer parser as soon as possible, to make for the smoothest upgrade. The old cef-latest parser will be removed at some point in the future. In your data, the field #type contains the name of the parser, so any queries you may have that searches for this field need to accomodate this change.

The old cef-latest parser would duplicate certain fields, which the new claroty-ctd parser will not. The fields which were previously duplicated, would be present both under the Vendor namespace (e.g. Vendor.srcIp ), and as a field mapped to CPS (e.g. source.ip ). If the value of two such fields is byte-for-byte the same, the new parser will no longer preserve the vendor-specific field, but only the CPS field. If the value of the two fields differ, both fields will be preserved. This means the following fields will no longer be present in the parsed data, when using the new parser:
