01 Where we look
Your stack watches your perimeter. We watch everywhere else.
Five collection layers. The further down the stack, the fewer organisations have any visibility at all — and the more valuable what is found there turns out to be.
Five layers down, almost nobody is looking.
01
Surface web
Indexed sites, registries, filings, court records, news and social platforms.
Anyone can search it. Almost nobody searches it properly.
02
Deep web
Databases behind forms and paywalls: corporate registries, litigation dockets, procurement records.
Not hidden — just not indexed.
03
Breach corpora
Aggregated credential dumps, infostealer logs and combolists tracked against your domains.
Where your password is, right now.
04
Darknet markets & forums
Access brokerage, stolen data listings, ransomware leak sites and closed criminal forums.
Where exposure becomes an incident.
05
Partner network
Trusted UK and international partners extending reach beyond what any firm of our size should claim alone.
The honest limit of a specialist.
02 Capabilities
Four areas. Sixteen lines of work.
Run individually or as a standing retainer. Every one produces a written, sourced deliverable — not a dashboard login you will never open.

Four engagements, redacted.
Client identity and operational detail withheld. What remains is the shape of the work and the outcome it produced.
72h Detection to takedown
Global law firm
A lookalike domain targeting the firm’s own clients
A phishing campaign was identified running through a domain built to impersonate the firm. Mayfield evidenced the infrastructure and supported the takedown with the registrar.
0 Fraudulent transfers completed
Financial institution
Employee credentials offered for sale on a darknet market
Monitoring surfaced employee credentials offered for sale on darknet markets. Alerting allowed the institution to force rotation and harden approval controls before the access was used; the attempted fraudulent transfers did not complete.
Fraud Uncovered in enhanced screening
Corporation
What a vendor’s own disclosures left out
Enhanced due diligence conducted on a vendor uncovered fraudulent representation and material compliance red flags — documented to a standard the client could act on rather than merely note.
Early A warning, not a post-mortem
Non-governmental organisation
A coordinated misinformation campaign, still forming
Standing monitoring of reputational threats detected an emerging coordinated misinformation campaign. Early-warning reporting gave the organisation time to prepare a response rather than react to one.
04 Who we work for
Specialists, not generalists.
Four sectors where being wrong is expensive and being late is worse.
- Law firms
- Litigation support, client protection and impersonation defence.
- Financial institutions
- Credential exposure, fraud prevention and counterparty screening.
- Corporations
- Vendor due diligence, supply-chain risk and executive protection.
- NGOs & foundations
- Reputational monitoring, misinformation early warning and staff safety.
Also NGOs, private investigators and SMEs — same method, scoped to the exposure.
05 The firm
Incorporated 2024. Staffed considerably earlier.
Mayfield brings together professionals experienced in data analysis, cyber security, research and compliance. We collaborate with trusted partners across the UK and internationally to extend our monitoring reach beyond what a firm of our size should claim on its own.
A young company selling to law and finance has exactly one credible move: be unusually specific about method, sourcing and limits. That is what the rest of this page is.
- Curiosity
- We keep asking until the picture is complete, not until it is convenient.
- Ethics
- Lawful collection only. We document our sources and we decline work we cannot stand behind.
- Innovation
- We refine method continuously to match an information landscape that does not stand still.

08 Engagement
Every engagement begins with a pilot.
Before entering any long-term arrangement, Mayfield runs a pilot phase. You see the capability working on your own organisation — dark web monitoring, OSINT analysis, breach detection — before anything scales. It is how we demonstrate accuracy, confidentiality and measurable outcome, and how every client partnership starts on proven value rather than on a promise.
- 01
Scope
We agree what to watch: domains, executives, brands, counterparties.
- 02
Collect
Monitoring goes live across open, deep and closed sources.
- 03
Report
Findings delivered in the format your legal or compliance function needs.
- 04
Decide
You judge the value on real findings, then choose whether to scale.
Tell us what you would want watched. We will scope a pilot on it, in writing, before anything is agreed.
