Are you saying it's resistant to penetration by Russian security services? Sorry if I don't take your word for it. They have just successfully hacked into several of the top financial institutions in the world: http://www.networkworld.com/article/2691902/security0/russia...
They got away with customer data and who-knows-what-else. I'm pretty sure JP Morgan has a bigger cyber-security budged than the whole state of Estonia, many times over. And then check the laundry list of these: http://cybercampaigns.net/
The basic truth is: we still don't quite know how to design digital information systems that can resist attacks from very persistent or nation state level actors. Even if these are air-gaped (as demonstrated by Stuxnet).
JP Morgan has ~$2.5 Trillion under management, annual revenues near $100B/year, and profits around $20B/year. Estonia's GDP is $25B and their annual tax receipts are about $4B/year. It's quite easy to assume that JP Morgan spends far more on security than the entire country of Estonia.
