We build sustainable security that lasts beyond the next update
Founded in 2009, Silverskin is a pioneer in offensive security and a leader in continuous penetration testing. We test your systems the way real attackers would, but we’re on your side. Our work gives you clear visibility into your security posture and helps you build long-term resilience.
Why security needs a hacker's mindset
Silverskin was founded in Helsinki in 2009 with one clear mission: to approach security from the attacker's point of view. We’ve believed from the start that the best way to defend systems is to first understand how to break them. Over the years, we’ve evolved our services to focus on what delivers lasting value. Penetration testing remains our core, shifting from one-off projects to continuous testing that keeps up with today’s rapid development cycles.
Silverskin is part of Patria Group, a trusted defense and technology provider. While we operate internationally, our team and values are firmly rooted in Finland.
"Silverskin" is the thin protective layer around a coffee bean. Our name reflects our mission to protect what matters.
How we work with you
Attacker Mindset
"You found really valuable findings that help us learn and understand what to pay attention to in the future."
We don’t stop at surface-level scanning. We simulate real attacks to uncover real risks, helping you fix what actually matters.
Security Partnership
"Silverskin’s continuous testing service is one of the few processes that runs consistently at Sievo. They have firmly established themselves as an integral part of how we work."
We deliver more than reports. We bring knowledge into your team and work alongside your experts to raise your security maturity over time.
Sustainable Security
"For Koho Sales, Silverskin’s continuous testing service requires very little administrative effort. The service doesn’t need extensive preparation, and Koho doesn’t have to spend time transferring information between different vendors and testers."
Security isn’t just a checklist. We help embed it into your design, development, and decision-making so it sticks.
