1. A technical system for securing application data, the system comprising: an application server associated with a virtual private data-store for application data, the application server comprising: a data security module (DSM); a data security module adaptor; one or more hardware processors operatively coupled to the DSM and the virtual private data-store, wherein the one or more hardware processors are configured to: monitor data between an application and the virtual private data-store via an objection relational mapping (ORM) layer; detect, based on at least a key flag, whether the monitored data at the ORM layer comprises sensitive data; determine, via the DSM, whether a key entry is associated with the detected sensitive data; in response to the determination, the DSM processes the sensitive data to secure the data, wherein the data security module adaptor maps the monitored data flowing from the DSM to the ORM; wherein the DSM operating at the ORM layer detects whether the monitored data at the ORM layer comprises encrypted sensitive data; and wherein the DSM orchestrates key management requests and responses at the ORM layer.
