Valkyrie

What Valkyrie does

Valkyrie (legal entity Valkyrie (GB) Limited) is a London-based boutique security and investigations firm founded in 2009 by Floyd Woodrow MBE DCM and Peter Malmstrom. The company delivers an integrated cyber and physical security proposition to three primary client segments: corporate entities, government agencies (international), and high-net-worth individuals. Services span Technical Surveillance and Countermeasures (TSCM) bug sweeping, cyber security (penetration testing, vulnerability assessments, war gaming, digital forensics, cryptocurrency investigations), private investigations (litigation support, due diligence, insider threats, geopolitical analysis), covert surveillance, physical and personal security, crisis response, security training, and physical penetration testing, with a Cyber Essentials / Plus certification layer delivered in partnership with Forensic Control.

The underlying technology stack combines state-of-the-art TSCM equipment for electronic surveillance detection, digital forensics tooling for computers and mobile devices, and standard enterprise IT (Microsoft Azure AD, Microsoft 365) operated under ISO 27001. The firm does not operate a software platform; delivery is human-led by an in-house team drawn from 22 Special Air Service, Royal Marines, British Army, COBRA, and the UK Counter Terrorist Wing, with no subcontracting, and work is produced to evidential standard suitable for legal proceedings.

The business model is high-touch professional services sold directly to enterprise, government, and UHNW clients on a bespoke, quote-based, project and retainer basis via website enquiries, a 24/7 phone line, dedicated email, and in-person consultations at 15 Belgrave Square. Go-to-market combines direct enterprise field sales with thought-leadership earned media (Tatler, Life Magazine, WealthBriefing, Crime+Investigation, International Security Journal) and independent third-party validation (Chambers 2026, Legal 500 2026, Spear's Index 2025). The company is privately held with no disclosed funding, parent entity, or M&A activity, and operates from a single London headquarters with claimed global reach.
