Bug Bounty Switzerland, a Zurich-based CyberTech firm specialising in ethical hacking and continuous security testing, has secured CHF 12m in a Series A funding round jointly led by Direttissima Growth Partners and Deutsche Beteiligungs AG (DBAG).
The two investors contributed equally to the round. Direttissima is a European growth equity firm with offices in Zurich and Munich, bringing B2B technology scale-up expertise and a network of operator-investors to the partnership. DBAG is participating through its Long-Term Investment strategy, deploying balance-sheet capital outside of traditional fund-structure timelines.
Following completion of the deal, Direttissima partner Philipp Bolliger will take a seat on Bug Bounty Switzerland’s board of directors, while the founding team retains a majority of shares and remains central to setting the company’s direction.
The fresh capital will be channelled into international expansion, headcount growth, and accelerating the evolution of the platform from AI-assisted to increasingly autonomous security test orchestration.
Bug Bounty Switzerland was founded in 2020 and has been entirely self-financed since launch, remaining profitable throughout. The company’s heritage stretches back to Switzerland’s first bug bounty programmes in 2015. It currently serves more than 50 enterprise customers across financial services, critical infrastructure, global consumer brands, and the public sector, including the Swiss National Cyber Security Center (NCSC).
The company delivers continuous, outcome-based security coverage through its Cyber Resilience Shield, a subscription platform that combines AI-driven orchestration, codified testing playbooks, and a vetted global community of more than 16,000 ethical hackers. Increasingly, the platform also deploys offensive AI agents.
Customers can activate the service within 24 hours without requiring internal security specialists.
Bug Bounty Switzerland chief executive and co-founder Sandro Nafzger said, “As AI reshapes cybersecurity, organizations need protection that’s continuous, intelligent, and simple to adopt. That’s what we’ve delivered to some of Europe’s most security-conscious institutions — and what we’re now bringing to customers worldwide. With the support of Direttissima and DBAG, we’re making intelligent security testing the new standard.”
Direttissima Growth Partners partner Philipp Bolliger said, “Bug Bounty Switzerland combines three things that rarely come together: a differentiated product built on years of proprietary know how and data, profitable execution from a bootstrapped start, and a market in which continuous security testing is shifting from best practice to baseline. The team has earned the right to redefine and lead this category.”
