Trusted. Tested. Certified.
Proactive, AI powered security
Compliance by design
The Co-security model
Simple. Scalable. Seamless.
Who we are.
Founded in Helsinki in 1988, we’ve spent over three decades building and sustaining digital trust, confidence and equity across Europe. We’re privately held and independent which means we stay focused on our purpose, not chasing investor trends. Our team includes security researchers, threat hunters, compliance experts, and GTM experts from VADs and operators who get it. We’ve walked in your shoes. We know what works and what doesn’t.
What sets us apart.
Other vendors sell you tools and wish you luck. We co-create with our partners and invest in AI, threat intelligence, and managed services built specifically for Europe’s midmarket. We build what our partners actually ask for: a cybersecurity platform without the complexity, comprehensive without the bloat.
Outcomes, not tools.
We don’t measure success by licenses sold. We measure it by threats stopped, compliance achieved, and customers retained. Every service we deliver is tied to a business outcome you can actually report on.
We call it Co-Security.
We work beside you, not over you. No jargon, no overselling — just honest conversations about what we can do, how we do it, and where you take the lead. We share the work because that’s how real partnerships deliver real outcomes.
European heritage, global perspective.
We understand European regulations because we operate here. We understand global threats because we track them everywhere.
Built for scale.
Whether you’re managing 10 customers or 1,000, our platform grows with you without making you grow your overhead. More customers, same team, better margins.

Cybersecurity with a conscience.
We believe security and sustainability go hand in hand. From protecting vulnerable communities against cyber attacks to championing the next generation of cybersecurity talent, we take our responsibility beyond the platform.
“WithSecure enables us to focus on improving our customers’ businesses, not building security infrastructure. Their innovation gives us confidence, not just for today, but for tomorrow.”
“WithSecure is a critical partner for us — helping us meet the European compliance requirements our customers demand, while making collaboration effortless through short lines of communication and a strong joint go-to-market approach.”
“WithSecure is the partner we grow with. Their dashboards, insights, and expertise empower us as an MSP to deliver real value — for our business and for our customers.”
Built by people who know the business.
Our leadership team combines decades of cybersecurity, product, and enterprise tech experience from companies like Nokia, Microsoft, and F-Secure. We’re operators, not observers — and we’re building WithSecure for the partners and customers we understand firsthand.
