I've had numerous companies claim they "required" E&O but in actuality, do not.  They only want abstractors to carry the insurance so they can pass the buck down to them if there is an issue.  They don't do that if you don't carry the insurance.     In my opinion, a product that carries insurance is what a Title Company provides and charges a fee reflective of that.   Why are abstractors "insuring" their product for non-insurance prices?   This is why banks use this arrangement, to save money over the title companies,   and yet they expect us to insure our product???   Clearly a 'have their cake and eat it too' situation.

The abstractors I've known who have been sued, are the ones with E&O.  If you don't carry it and be clear that your product is not insured, you will save yourself alot of anxiety, not to mention unnecessary premiums.
