About HeaderLume
HeaderLume is an offline email forensics application for macOS. It parses raw RFC-5322 headers, traces a message's transit route hop by hop, verifies SPF, DKIM, DMARC, and ARC authentication, and generates court-ready PDF evidence certificates — entirely on the examiner's Mac. It is built for forensic examiners, litigation and eDiscovery teams, incident responders, and law enforcement: anyone whose findings must survive cross-examination.
HeaderLume is built by ProfWorkBench, LLC and distributed exclusively on the Mac App Store. All analysis runs locally inside the macOS App Sandbox — no accounts, no tracking, no cloud processing — and the Absolute Zero Telemetry switch blocks every outbound network socket for air-gapped examination. The app is localized in 15 languages.
Approved boilerplate
HeaderLume is an offline email forensics app for macOS that turns raw email headers into defensible evidence. It parses RFC-5322 headers, maps the sender's transit route hop by hop, audits SPF/DKIM/DMARC/ARC authentication, streams 10 GB+ MBOX archives, and exports court-ready PDF certificates with SHA-256 evidence hashes plus Concordance load files for Relativity. Analysis never leaves the Mac. HeaderLume is free to download on the Mac App Store, with Premium and lifetime Genesis Partner licenses for working examiners, firms, and labs.
