Kraken is secure. We store your data on secure servers on Amazon's EC2 and S3 services using Amazon's Security Groups and S3 security policies. Access to the servers are controlled using public key encryption.
We use SSL throughout the app, on all pages, to secure every last transaction and piece of data, for all accounts.
In terms of security we use a similar approach to many SaaS solutions that require users to have access to an account in order to see any data. We use a layered approach combining access filters that run every time something is accessed as well as database queries that require users to have access to the account in order for data to be returned.
Finally, in terms of our internal processes and policy, we don't have easy access to your projects and data (ie. I can't simply log in as you to see what's in your account), and we only dig into the logs or the database when specifically required for troubleshooting. We don't resell or reuse your data in any way, nor do we have plans to.
