On 4 August we're running a live session on how an ex-NCA officer actually investigates a suspect online — starting from a single data point and building outwards. Live searches, not slides. Join us on Zoom, or watch the live stream on YouTube. And if you haven't picked it up yet, our free Forensic Web Capture extension is on the Chrome Web Store. All below.

How to Investigate a Suspect Online

Led by Mark Bentley • Ex-NCA & CEOP • Live Q&A

Learn how an ex-NCA (National Crime Agency UK) officer would approach investigating a suspect online. Starting from a single data point — a name, an email address, a phone number, a username — you'll see the full process of building a digital footprint on a subject: how to pivot between identifiers, how to verify what you find, and how to know when a result is worth chasing.

Mark will also cover UserSearch's newer capabilities — Cyber Intelligence, Corporate Intelligence, and SargeBot, an AI agent that runs an investigation autonomously and produces a full report.

Forensic Web Capture

Chrome Web Store • Free & unlimited • Chrome · Edge · Firefox

Court-grade web evidence, captured entirely on your own machine. Preserve any website or social media page as tamper-evident digital evidence — full-page screenshots, screen recordings, and page-source snapshots, each SHA-256 hashed, sealed, and independently timestamped the instant you capture. Nothing is uploaded: no cloud, no telemetry, no analytics.

Dedicated handlers capture Facebook, Instagram, X, YouTube and TikTok as they really look, with one click to expand comment threads before capture — and full ChatGPT, Claude and Gemini conversations can be preserved as sealed evidence. Usernames, emails and phone numbers are extracted automatically and flagged when the same identifier reappears across captures. On-device OCR makes every screenshot full-text searchable, and you can monitor a URL to auto-capture the moment a page changes.

Every case carries a chain-of-custody timeline, append-only contemporaneous notes, and subject dossiers. Integrity rests on a tamper-evident Merkle manifest, an Ed25519 seal per install, and RFC 3161 trusted timestamps corroborated on the Bitcoin blockchain via OpenTimestamps — all independently verifiable offline, by anyone, with no extension required. Output as one-click PDF and Word reports or portable, self-verifying BagIt evidence bundles.
