How PIs Use DFIR Support
WHEN TO BRING IN TECHNICAL LAB SUPPORT
Whether you are tracing an online persona, investigating a spoofed email, or following stolen crypto assets, we scope the technical research around your case objective.
When traditional database checks stall, we correlate usernames, email accounts, archived web content, corporate registrations, and connected online infrastructure.
Report Output for Your Case
Uncovers corroborated digital footprints and new investigative pivot points for fieldwork.
When your client is targeted by spoofed emails, harassment, or lookalike domains, we dissect RFC-5322 headers, DNS records, hosting history, and infrastructure overlap.
Report Output for Your Case
Identifies originating infrastructure, technical patterns, and practical boundaries of attribution.
When an assignment involves stolen funds, romance/investment scams, or wallet addresses, we trace publicly observable on-chain transaction paths and exchange hops.
Report Output for Your Case
Produces a clear transaction-path summary and technical brief ready for your case file.

Alongside our 6 core OSINT and cyber investigation services, private investigators frequently subcontract bulk audio/video transcription, foreign-language translation, bespoke tech research, and secure communications setup through our Specialist Operations Lab.
Surveillance Audio, Interviews & Calls
Have dozens or hundreds of hours of field surveillance audio, recorded witness interviews, or client recordings? We convert lengthy media files into structured, timestamped, searchable text so your investigators can pinpoint key statements immediately.
Foreign-Language Surveillance & Comms
Working an international assignment or non-English surveillance audio, WhatsApp voice notes, or recorded statements? We translate 99+ foreign languages into time-aligned, searchable English documentation.
Emerging Apps, Trackers & Hardware
Encountered an unfamiliar stalking/spyware app, IoT tracker, or niche digital platform during a case? We produce bespoke technical research reports explaining how the technology works and what artifacts it leaves behind.
Encrypted Field Comms & Lab Development
Harden your investigative agency with end-to-end encrypted communication channels, data-at-rest encryption assessments, non-custodial crypto wallet setup, or internal digital forensics unit development.
SOURCE-DATA SCOPE
Share the lead or digital artifact from your assignment, and we will scope the research to establish relevant context, relationships, and findings.
SRC_01 // INFRASTRUCTURE
Registration history, WHOIS/RDAP records, DNS configurations, passive DNS history, hosting providers, TLS certificates, and observed infrastructure changes.
Analytical boundary: Uncovers historical registrant clues and shared hosting/DNS infrastructure across connected sites.
SRC_02 // NETWORK CONTEXT
Autonomous System (ASN) ownership, ISP allocation, routing context, reputation data, exposed services, and infrastructure relationships.
Analytical boundary: Treats geolocation as network context—distinguishing residential ISPs from VPNs, data centers, and CGNAT.
SRC_03 // ACCOUNT FOOTPRINTS
Publicly available account associations, breach-exposure metadata, username reuse, domain ties, and digital-footprint research within the assignment scope.
Analytical boundary: Scoped strictly to lawful open-source and commercial intelligence repositories.
SRC_04 // TRANSIT ARTIFACTS
Full RFC-5322 message artifacts, bottom-up server routing hops, SPF/DKIM/DMARC authentication results, timezone skews, and sending infrastructure.
Analytical boundary: Separates forged display names from authentic server-recorded transit hops.
SRC_05 // DECEPTION VECTORS
Malicious URLs, typosquatted domains, sender patterns, redirect chains, credential-harvesting hosts, and shared campaign infrastructure.
Analytical boundary: Identifies whether multiple lures or scam domains share backend infrastructure.
SRC_06 // ON-CHAIN LEDGERS
Publicly observable wallet-address tracing, transaction-path analysis, cluster associations, and identifiable exchange or service deposit endpoints.
Analytical boundary: Maps on-chain fund flows to identifiable service boundaries or cash-out points.
SRC_07 // OPEN & DEEP WEB
Structured research across public records, web content, social and professional platforms, archived pages, and connected corporate or personal entities.
Analytical boundary: Correlates multiple independent identifiers to eliminate false-positive name matches.
SRC_08 // SYNTHESIS
Cross-referencing field identifiers (names, phones, addresses, timelines) with technical artifacts to establish corroborated investigative leads.
Analytical boundary: Clearly distinguishes verified technical links from unconfirmed leads requiring field follow-up.

QUESTIONS FROM INVESTIGATORS
Have an active lead or client request? Send the indicator type and jurisdiction to confirm turnaround and scope.
We act as your behind-the-scenes technical subcontractor and digital research partner. You bring the field context and client relationship; we handle the technical OSINT, email header analysis, domain/IP correlation, or cryptocurrency tracing and deliver a clear report you can use in your investigation.
Share the indicator that prompted the inquiry: a domain name, IP address, raw email (.eml/.msg) or header, phishing link, cryptocurrency wallet address, username/account, or a summary of the investigative question. We will define a focused scope before work begins.
No. We work discreetly behind the scenes with you and operate on a zero-testimony support model. You retain full control of your client relationship and case management.
Yes. Digital leads frequently overlap—an email header reveals a domain and IP address, or a phishing scam links to a cryptocurrency wallet and online persona. Our Targeted OSINT Report correlates all relevant indicators within the agreed scope.
