A computer-implemented method includes: receiving, by a computing device, a vault access request for vault credentials stored by a vault server; verifying, by the computing device, whether a source of the vault access request originated from a multitenant application server; preventing, by the computing device, access to the vault server and the vault credentials when the source of the vault access request has not been verified as originating from the multitenant application server; obtaining, by the computing device, vault credentials from a vault server based on verifying that the source of the vault access request originated from the multitenant application server; and executing, by the computing device, a multitenant application task using the vault credentials.
