By default, Prowler will generate the CSV and JSON-OCSF report.
prowler <provider> -M csv json-ocsf json-asff htmlIf you want to generate the JSON-ASFF (used by AWS Security Hub) report you can set it using the -M/--output-modes/--output-formats, like:
prowler <provider> --output-formats json-asffBy default, all the compliance outputs will be generated when Prowler is executed. Compliance outputs will be placed inside the /output/compliance directory.
Custom Output Flags¶
By default, Prowler creates a file inside the output directory named: prowler-output-ACCOUNT_NUM-OUTPUT_DATE.format.
However, both the output file name and directory can be personalised:
- Custom output report name: you can use the flag
-F/--output-filenameprowler <provider> -M csv json-ocsf json-asff -F <custom_report_name> - Custom output directory: you can use the flag
-o/--output-directoryprowler <provider> -M csv json-ocsf json-asff -o <custom_report_directory>
Note
Both flags can be used simultaneously to provide a custom directory and filename.
prowler <provider> -M csv json-ocsf json-asff \ -F <custom_report_name> -o <custom_report_directory>Output timestamp format¶
By default, the timestamp format of the output files is ISO 8601. This can be changed with the flag --unix-timestamp generating the timestamp fields in pure unix timestamp format.
Output Formats¶
Prowler supports natively the following output formats:
- CSV
- JSON-OCSF
- JSON-ASFF

Note
Since Prowler v3 the CSV column delimiter is the semicolon (;)
JSON-OCSF¶
The JSON-OCSF output format implements the Detection Finding from the OCSF v1.1.0

JSON-ASFF¶
Note
Only available when using --security-hub or --output-formats json-asff
The following code is an example output of the JSON-ASFF format:
