Fieldfisher Advises on International Strategic Sale of Cybersecurity business Onevinn
Innovation

European law firm Fieldfisher has advised cyber security business, The Haven Group, on the auction sale of its Swedish subsidiary Onevinn to Allurity. Onevinn specialises in intelligent security and managed services. By leveraging AI, automation and threat intelligence, Onevinn enables smarter, faster protection against an increasingly complex cyber threat landscape as demand for trusted and capable European players continues to grow.
Fieldfisher provided legal support and advice to the Haven group, backed by C5 Capital which invests in high growth cyber security, space and nuclear energy businesses. Fieldfisher also advised on related reorganisations and financing matters.
Allurity, a tech-enabled cybersecurity service group, is backed by Trill Impact, an impact investor with a commitment to innovation and positive societal impact. Onevinn's capabilities reinforce Allurity's support of Europe's growing reliance on cloud services and enabling a safe digital world.
The Fieldfisher team was led by Corporate Partner Thomas Colmer and included Senior Associate Joshua Cronin and Solicitor Alexandra Basford, Funds Partner Dale Gabert, Tax Partner Andrew Prowse, Banking & Finance Partner Robin Spender and Director Igor Stermsek all from Fieldfisher's London office and Partner Ingrid Dubourdieu and Senior Associate Eugenio Mancini from Fieldfisher's Luxemburg office. Fieldfisher worked closely with financial advisers Stifel Global Technology Group, Swedish law firm Mannheimer Swartling, US law firm Nelson Mullins and tax advisers Grant Thornton. Allurity was advised by Cederquist and management by Setterwalls.
Commenting on the deal, Thomas said: "This was a great team effort delivering a great result. We are delighted to close another international private equity technology M&A deal. Cyber security remains a real strength at Fieldfisher across the spectrum of legal needs. We are a leading firm in this space advising on policies, cyber readiness, training & compliance, breach containment, insurance, litigation, regulatory outreach & defence, fundraising and mergers & acquisitions."
Andre Pienaar, founder of C5 Capital and Chairman of the Haven group said "Thomas and his colleagues worked seamlessly with C5 Capital, the Haven group and our other valued advisers allowing us to execute at pace. I am grateful for their support and guidance. The Fieldfisher team have been true trusted advisers."
Arno Robbertse, CEO of the Haven group said "I have enjoyed working with Thomas and the Fieldfisher team. They provided invaluable insights at every stage and at all hours. I look forward to working with them again."
This deal follows a number of international private equity technology M&A deals for Fieldfisher, including advising on the sale of cybersecurity specialist Garrison Technology Ltd to Everfox and transatlantic technology private equity platform deal, advising Board Intelligence on K1's Strategic Growth Investment in AI-Powered Board Management Software Platform, Board Intelligence.
