There is no silver bullet, but Dotenvx splits your secrets into two separate locations.

1. The private decryption key - which lives on Vercel in this example 2. The encrypted .env file which lives in your source code pushed to Vercel

Attackers only got access to the first (as far as I know was reported). So your secrets would be safe in this attack if using Dotenvx. (A private key is useless without its corresponding encrypted .env file. Attackers need both.)
