Hashing is never a great option for PII data (even less so for PCI data).

For instance, suppose someone has applied a cryptographic hash to first names.

All an attacker needs to do is find a list of common names, hash them all, and see which hash values match.

What’s the solution?

Use data encryption instead of hashing. If you are using a cloud provider for your data storage, you would most likely have default, at rest encryption. See this post for Redshift specific data encryption.
