We are compiling best practices at https://cwiki.apache.org/confluence/display/FINERACT/Securing+Fineract. If you have ideas, please help by putting them there.

While organizations like Mifos are free to bundle the fineract system in their offering per the terms of the license, that does not imply that Fineract has endorsed that particular deployment approach.
