It’s called the “Dark Web” for a reason. Monitoring tools may exist but they do not and can not cover every avenue, or even a small fraction of them.
There may be scanners etc but I think your best bet is to ask the security provider for recommendations. They identified the issue and notified you - it sounds like they’re a third party worth keeping around.
In the mean time, assume that creds can be stolen and there’s nothing you can do about it: what do you do about that? You have many options: rate limiting, IP checks, detecting unusual activity. I’d start there.
