title: Encrypting the database at rest without paying?
body: <p>Right now the only way to encrypt a Cassandra database at rest seems to be with their enterprise edition which costs thousands of dollars: <a href="https://stackoverflow.com/questions/32584253/how-to-use-cassandra-with-tde-transparent-data-encryption">How to use Cassandra with TDE (Transparent Data Encryption)</a></p>
  
  <p>Another solution is to encrypt every value before it enters the database, but then the key will be stored somewhere on every server in plaintext and would be easy to find.</p>
  
  <p>I understand they offer "free" use for certain companies, but this is not an option and I am not authorized to pay $2000/server. How do traditional companies encrypt their distributed databases?</p>
  
  <p>Thanks for the advice </p>
