Private intelligence, digital forensics, and litigation support for legal professionals, businesses, and individuals.
Greyline is a UK registered private intelligence firm. We investigate quietly, document properly, and deliver findings that clients, courts, and counterparties can rely on.
Every report is signed by a named principal. Every method is defensible in court.
Asset tracing, witness location, expert reporting and continuous case intelligence for solicitors, barristers and family offices.
Pre-hire vetting, vendor and supply-chain risk, digital exposure and the intelligence businesses need before they commit capital or trust.
Quiet, documented inquiry into relationships, romance fraud, and the people or threats that matter most to you and your family.
A faster way in, if you already know roughly what you need.
Funding a build, a business, or a purchase from a distance. An independent, documented visit confirms what's actually there before your next payment.
Before you marry, cohabit, or commit financially: a thorough, discreet picture of who someone actually is.
Before you sign, invest, or extend credit: verified facts about the person or company on the other side of the deal.
Met someone online and the story doesn't quite add up. A discreet, evidence-based check on whether they, and the relationship, are genuine.
Standard background checks miss what actually matters. Vetting that goes deep enough to protect a critical hire.
A business connection, asset, or investment in Nigeria or West Africa. Verified on the ground by named partners, led by a UK-based investigator.
Recurring or fixed-scope engagements with a defined deliverable and a set cadence, for situations that recur or need a fixed answer by a fixed date.
Independent on-site verification of property, business, land and assets
Authenticity assessment of contested audio, video and images
A pre-emptive audit of your own public exposure
Continuous monitoring for impersonation and exposure
Every engagement begins with a confidential inquiry, submitted through our encrypted form, and proceeds to a written scope before any work is committed.
Use the encrypted intake form. Provide a high-level summary, no sensitive evidence required at this stage. An analyst, not a salesperson, reviews every submission.
Within 24 hours, we arrange a call to understand the matter, identify what is and isn't in scope, and explain our approach.
You receive a written engagement letter setting out the work, the deliverable, the timeline, and the fee. Nothing is committed until you sign.
Once the engagement letter is signed, work begins.
Romance fraud has always relied on a constructed identity. What has changed is how convincingly that identity can now be built and defended in real time, and what that means for the advice we give people trying to verify who they are really speaking to.
Read →A source is not a finding. Before any statement enters a Greyline report, it is graded for reliability and credibility using a modified NATO Admiralty Code. Here is why that discipline matters and what it looks like in practice.
