You absolutely should invest in security. Your business is your baby and there are going to be outside threats to your baby either from disgruntled employees or the general public. The fact of the matter is that security is a necessity that shouldn’t and can’t be overlooked. Investing a little in security can pay large dividends down the road. It’s like insurance. You hope that you never have to use it but if you ever need it you’ll be happy it’s there.
