Perseus Technology builds forensic software and delivers digital forensics, incident response, wireless security research, and AI-driven security engineering — for investigators, legal professionals, and organisations where technical depth and operational judgement are non-negotiable.
Three specialist tools for digital forensics. Subscription licences with floating seats — no dongle, and no evidence data ever leaves your workstation.
Mount disk images or physical devices, recover deleted data, and generate a court-ready report.
Parses encrypted and unencrypted iOS backups and ties the contents to people and timelines.
Drop a sysdiagnose into the app and get a PDF verdict with confidence level and recommended actions.
The same methodology as in the software — delivered as expert services with evidential value and operational judgement.
Disk, mobile, and message analysis with evidential value. Support for criminal investigations, disputes, and private inquiries — regularly engaged as expert witness.
Initial assessment, containment, prioritisation, and technical analysis under time pressure. Leadership and decision support during serious incidents.
Offensive and defensive signal analysis. Research and specialist work where offensive methodology meets defensive engineering.
AI-driven security engineering: optimisation, decision support, and platform work built for real operational needs — locally, without cloud dependencies.
The career started early — as a teenager he traced virus writers for the FBI during the Melissa and Love Bug investigations. Since then: penetration testing, CSO at Klarna, teaching adversary tradecraft, and regular engagements as an expert witness before Swedish district and appeals courts. Perseus is that experience, turned into software and delivery.
We'd be glad to talk about how Perseus can support your organisation — investigations, incidents, research, or licensing.
