Sounds like your best next step is to become an exemple of software/infrastructure best practices - get everything in the best backup/recovery solution you can, document every detail any time an issue comes up, and above all treat your people like the vaaluable assets they can be.

You may be doing any of that already, since I don't know anything about you except your one comment.

But the answer to your fear of exploitation is avoid making people hate you/your environment enough to want to protect themselves from it.
