Hi,

Is there a way to encrypt traffic between three Elasticsearch nodes using SSL/TLS?  
For example we have set up ES cluster and the details are as mentioned below:-

```
es1.example.com
es2.example.com
es3.example.com

```

Can we encrypt traffic between [es1.example.com](http://es1.example.com) \<-\> [es2.example.com](http://es2.example.com) \<-\> [es3.example.com](http://es3.example.com) ?

Any help will be highly appreciated. Thanks in Advance and i look forward to hearing from you.

Best Regards,

Kaushal

Hi Mark,

Do i need to buy a license to enable [https://www.elastic.co/products/stack/security](https://www.elastic.co/products/stack/security) in my setup?  
Please comment.

Yes, security requires a commercial license.
