What happens if Kubera servers are breached?
First of all, we don't store any of your banking credentials (See the answer to the question: Does Kubera have access to my online bank account?). If Kubera servers were to be breached, your banking credentials are totally safe.
Secondly, all your data in Kubera is encrypted at rest on Amazon servers. So, even if someone hacks in and gets hold of a backup of the database, it’d be useless, because they wouldn’t have the key to decrypt it.
Kubera uses HTTPS on all pages, and HSTS to ensure browsers only ever connect to us over a secure connection. So, someone hacking into your data on transit is less likely.
