Ask HN: What company would you trust with the security of your javascript app?

Specifically, with the proliferation of client-heavy javascript apps, assuming a new hacker can master html/js/css, is there a provider out there that provides a secure backend-as-a-service for them to build on? What I mean is, figuring out ssl, getting the site to work on https, setting up, configuring, and managing the servers invovled, pretty much everything other than client side development, is there a best in class solution that provides all that? Let's assume that the app is usuable without signing up, and is designed to be used in one-off use cases where there is no point to save ones progress or past work, and now their is a feature request to be able to store the result of the workflow for future loading/editing. What's the simplest way for this developer, assuming they have money to throw at the problem, to get all that boring but necessary backend/security stuff handled? Obviously if billion dollar companies we can only assume use best practices can still get hacked, any provider of a service such as I have described is selling a promise they can't quite keep, but anything is better than not being able to finish my app for a year while I teach myself all the backend/security stuff. What would you recommend someone in my position do? Any advice would be greatly appreciated.
