Cossack Labs’ Acra is a suite of database protection tools that are easy to use, deploy and automate. Acra enables front-end application code to selectively encrypt data with a set of encrypt-only keys. The encrypted data is then transmitted (via an Acra proxy service) to the database. It can be deployed in both traditional database-frontend web services and large, microservice-rich infrastructures. The Acra server can be configured to detect unexpected requests and take appropriate action.”]
