Its a matter of when, not if
If you believe you won't be hacked, then you are not paying attention. Organizations are regularly attacked by hackers, and they aren't just trying to beat their way into your business. Rather, they are using social engineering to sneak in. A recent victim of a hacking attempt was Mailchimp which was hacked via social engineering, which involves tricking people into giving up information that is then used in furtherance of the hack (see link).
