Contact
GreyFern does not publish a general contact directory — low profile starts at home. The routes below are the only public-facing addresses. Every engagement starts as a scoped conversation, and we'll tell you straight if it isn't work we can take.
New work, scoping questions, and requests for proposal. Reaches our client office. Tell us the target, the decision behind it, and your authority to authorize the work — we'll take it from there.
GreyFern is registered in the United Kingdom and privately held. Operators are distributed and work from wherever the engagement needs them; there is no walk-in office.
What we'll ask before we scope anything. Who the target is, what decision the intelligence supports, and — non-negotiably — that you have the standing and the authorization to have us look. No signed scope, no engagement. It's the discipline that has kept our record clean since 2016, and it starts at the first email.
A note on discretion
Most of what we do never appears anywhere a target can see it. We do not publish client names, engagement details, or operator identities — the same discretion we'll extend to you is the reason you can trust it.
Already working with us on a live engagement? Your handler is your contact, over the channel you were briefed on. Public email is for new inquiries only.
See first. Move last. Start a scoped conversation and we'll tell you what a competent adversary can already see.
