# Kinesis Data Analytics

* **Kinesis Data Analytics is the easiest way to analyse streaming data**, gain actionable insights, and respond to your business and customer needs **in real-time**.
* It **takes care of everything required to run your real-time applications continuously and scales automatically**.\

* **Kinesis Data Analytics encrypts all data both in transit and at rest**.
* **Encryption in transit is enabled for all Kinesis Data Analytics applications** and cannot be disabled and your **application's code and reference data are encrypted at rest**.
* You can also **encrypt data on the incoming Kinesis data stream using `StartStreamEncryption`**.\

* All **data in transit is NOT automatically encrypted by default in Kinesis Data Firehose**.\

* **Athena uses TLS encryption for data-in-transit between Athena and S3, and between Athena and customer applications accessing it**, but this is **not true for Kinesis Data Firehose**.
