I am the bank's security officer. I am the BSA officer, one of two compliance people, loan officer,and whatever else is needed to be done. We are a small farming community bank of $80M strong with two branches. Is it effective? I hope so as I personally feel responsible for all 35 employees, keeping our depositors safe as well as the buildings themselves. I once was told by a former President that I tried to run too tight of a security ship. My response was, "until you have held a sobbing teller in your arms after an armed robbery, then you can talk to me." He didn't bug me about security after that. IMO, you can not put a price on security.
