Not being a target is the only surefire way to not get hacked. Every system has vulnerablities and anyone with enough knowhow, time and criminal energy can hack it. Usually it's not the computers or networks that have the holes but the people that run it. Not only the technicians but every small office worker. I doubt you can buy better humans with money.
I assure you the latest hack of Sony Pictures was either done from the inside or through careless humans and not through the front security defenses.
How would you combat that? Make the life of your employees a living hell with extreme security policies?
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
