Hi there, we don't provide anything like that -- at least as far as I understand what they mean. It sounds like slightly spammy security marketing FUD to me to be honest.
I can't make security decisions for you, but I'd encourage you to make sure you understand exactly what each one of those things are, and what they can do for you, before you make any decisions.
We're pretty confident in our existing security measures, as outlined in giles' post above. Of course we're always open to suggestions about how we could improve things, so if you have any specific ideas, do let us know and we can look into it, or maybe answer in more detail. And, naturally, if there are any security researchers out there that spot particular vulnerabilities, do give us a shout via developers@pythonanywhere.com.
