Silverskin

Silverskin is a Finnish offensive security company founded in Helsinki in 2009, partially owned by Patria Group, a defense and technology provider. The company specializes in penetration testing and continuous security testing services, positioning itself as the Finnish market leader in this space. Silverskin's core methodology is built around an attacker's mindset — simulating real-world attacks to identify vulnerabilities across hardware, software, networks, and personnel. Rather than conducting one-off assessments, the company emphasizes continuous testing models that align with modern, rapid development cycles. Technical findings are translated into actionable business recommendations rather than purely technical reports. The company serves over 400 clients across various industries, delivering more than 300 tests annually to over 100 clients per year. Clients include organizations in telecommunications, healthcare, fintech, and public sector. Silverskin operates with a team of 27 security experts and reported a turnover of 1.9 million euros. Silverskin holds CREST certification for penetration testing services and employs experts certified by GIAC and OffSec. The company is also a Reliable Partner certified by Vastuu Group and holds credit ratings verified by Suomen Asiakastieto and Bisnode. Beyond delivering test reports, Silverskin positions its engagements as long-term security partnerships, working alongside client teams to improve security maturity and embed security practices into design, development, and organizational decision-making processes.
