How do you brief a reputation management firm on a client without compromising confidentiality?

You can brief a reputation firm thoroughly on a sensitive client without compromising confidentiality, and the trick is structure rather than withholding. Start with the NDA in place, covering the firm and anyone it works through. Then run the briefing in a structured way that separates what the firm needs to act from what it does not need to know yet: the goals and the definition of success, the hard constraints and red lines, the sensitive history that explains why a query or a Wikipedia section is fraught, and the prior work so nothing is duplicated or contradicted. Where the most sensitive detail is not yet essential, anonymize or hold it until the relationship and the workstream require it. The aim is a firm equipped to do the work correctly on day one, with the client retaining control over how much of the underlying detail travels and when. Vague briefings produce vague work; structured confidential briefings produce precise work without the exposure.
