Uncovering the facts, when no one else can.


Discreet investigative work for corporate and private clients. Lawful methodology, not limited by expertise, language or geography.
Who
Founded in the wake of the initial Ukraine invasion, cyber-security experts, current and former intelligence personnel, military, law enforcement and engineers from multiple European countries formed what is now Lambda Group.
What
From helping domestic abuse victims, to de-anonymising war-crime perpetrators and beyond. No case is too complex, none too small. From simple background checks to ISR, TSCM and counter-intelligence tasks, we know how to help.
Where
We've handled cases across the globe, Helsinki to Chicago, Riga to Transnistria. Comfortable in high-pressure situations and locations, with combined fluency in over 10 languages across the team. Point the way and we'll uncover the truth.
How
Our careful and thorough methodology relies on a combination of both open source intelligence (OSINT) techniques and expert tradecraft, enriched by the data and sensor platforms we have access to and have created ourselves, including SOLUS.
Why
We take great pride in our investigative work and often take cases pro bono for non-corporate clients. If you think you have a worthy cause, get in touch.

Linking scattered identifiers into complete intelligence.
SOLUS is our intelligence platform: a searchable graph and interactive query surface built from recaptured and live chat logs, telecom, dragnet scrapes, breach data, credential dumps, combolists, IoT, vulnerability scans and live multi-domain sensor data. We combine all these scattered identifiers to form a cohesive intelligence picture across multiple domains, including digital and geospatial, letting both us and our partners track exposure and potential threats as they emerge.
