Making some or all of the plan's data not public on EFAST2

I got an email from a client concerned about how much data is public on EFAST2.  They have had this plan since the inception of EFAST why now I don't know. 

The CEO is saying he was reading on all the instructions that he saw something that said you could request some or all of your data to not be made public.  I couldn't find anything in the instruction or on the website talking about this. 

I thought I would throw it out here before I go back and say, "can you show me what you are reading" if anyone has heard of this? 

I mean if you could do this every company would try and it would be more common knowledge around a firm like I work at which has hundreds of employees. 

Have we missed the boat on this somehow? 

Any help would be appreciated. 

Thanks

There are some instances in the instructions for the 5500 and the 5500-EZ that caution the filer not to reveal a Social Security Number.  For example, this comes up in the instructions for the Schedule DCG where it says:

"Do not use an SSN in lieu of an EIN. Because of privacy concerns, the inclusion of an SSN or any portion thereof on this line may result in the rejection of the filing."

On the Schedule H, there is an instruction that says "Schedule H and its contents are open to public inspection and may be published on the Internet. The inclusion of a Social Security number, or any portion thereof, at line 3c may result in the rejection of the filing. For privacy reasons, a Social Security number should never be shown on line 3c."

On the Schedule MEP, an instruction says "Enter the EIN of each participating employer.
Do not enter an SSN in lieu of an EIN. The Schedule MEP is open to public inspection, and the contents are public information and are subject to publication on the Internet. Because of privacy concerns, the inclusion of an SSN or any portion thereof on a Schedule MEP may result in the rejection of the filing."

You haven't missed the boat.
