A method for securing data access by containerized applications includes intercepting, by a first container executing on a first computing device and associated with a containerized application in a second container executing on the first computing device, a first Internet Protocol (IP) request from the containerized application. The first container determines that the IP request is addressed to a second computing device executing a resource that the containerized application is authorized to access. The first container encrypts a payload portion of the IP request and transmits, to the resource, a second IP request with the encrypted payload portion. The first container receives, from the resource, a response. The first container requests, from a third computing device, a cryptographic key for decrypting the response. The first container decrypts, with the cryptographic key, a payload portion of the response and transmits, to the containerized application, the decrypted payload portion of the response.
