I've used ISNet World for our prequalification for a few clients. They don't offer policies for purchase but there are 3rd party companies that sell policies. ISN is very particular with policy language and found alot of our policies had to updated to corporate the specific wording they wanted to see to get approval.

As a safety contractor we are on ISNetworld. Many of our clients require it and it does make on boarding easy. I’m not tasked with maintaining our information but I know it’s not too difficult. Avetta by contrast is very difficult especially for small companies . Is their any specific info about ISN you want to know?

We use it. Some of our customers that operate offshore under SEMS guidelines require us to keep our safety technicians current in ISN.

@Cole Atkinson I have a Behavior Based Program I can share with you. Send me your contact info and I will gladly share with you.

We do not use it to pre-qualify our subs, but we are part of it for clients we bid jobs on.
some of the documentation is a PITA.
I got an exemption for BBS - instead laying out the points of our program. Exemption accepted. I can look for our exemption request, if you'd like

I used it a lot for my previous employer. Have you gone through an audit yet? Make sure you've got your ducks in a row.
