Banshie

What Banshie does

Banshie was a Danish cybersecurity firm founded in 2015 and headquartered in Copenhagen, Denmark. The company specialized in offensive security capabilities and provided consultation services and solutions aimed at improving cybersecurity posture on business websites, with a functional emphasis on threat detection and incident response. Its business model was services-led, delivering expert-led engagements to business clients rather than a packaged software or platform product; publicly disclosed pricing details are not available.

Operating with a headcount in the 11-50 range under founder Thomas Birn (CEO & co-founder), Banshie served customers primarily within Denmark and the broader European market. The firm did not maintain disclosed offices outside Copenhagen, and no customer logos, segment mix, certifications, or patents are documented in the source material.

On June 27, 2025, Banshie was acquired by Truesec, a Nordic cybersecurity company, in a transaction advised by MCF (Mannheimer Swartling). The acquisition was structured to enhance Truesec's offensive security capabilities and accelerate its threat detection, response times, and overall cybersecurity service offerings. Following the transaction, Banshie's independent operating status was effectively ended as its operations were folded into Truesec.
