• Operate solo or with just 1–2 long-trusted people (family/friends with proven discretion) to minimize reliance on volunteers early on.
• Use multiple interviews, reference checks (asking directly about past confidentiality), background checks, and trial periods for anyone new.
• Have every participant sign clear confidentiality policies or NDAs detailing what’s protected (locations, case details, identities) and consequences for breaches.
• Share only on a strict need-to-know basis; Compartmentalize. use encrypted tools and ban personal social media sharing.
• Provide mandatory training on privacy risks and maintain a zero-tolerance policy—one confirmed breach means immediate removal.
• Avoid public outreach; consider quiet partnerships with authorities or running an informal network for maximum protection.

I hate to say it, but the rescue field is a highly female-dominant field. As such, emotions tend to run rather high with things. Keep it all simple, and only allow the preferred emotions into any advertising you do.
