Trusted. Proven.
Built the European way.
Powerful cybersecurity doesn’t have to mean complicated or resource-heavy cybersecurity. WithSecure gives your business scalable, enterprise-grade protection that’s built to be simple — so you can focus on running your business, not managing your security stack.
Cyber threats evolve daily.
Your security should too.
Cybersecurity, built the European way.
Proactive and Reactive Security.
Built in Europe.
Most security tools are built for large enterprises to either reduce attack surface or respond to cyber attacks. WithSecure does both — continuously hardening your defenses while AI-powered response stops threats before they become incidents. One platform, built in Europe, designed for midsize organizations that need enterprise-grade protection without the enterprise-grade complexity.

Here’s what they say.
Security that fits your business, not the other way around. Our customers choose WithSecure because we take the complexity out of cybersecurity — giving them the protection they need, the support they can rely on, and the confidence to focus on what actually matters.
“With WithSecure, and with Infinite, we got that working partnership. It wasn’t a huge ecosystem with lots of add-ons and bolt-ons: it’s a service that works exactly as advertised, and people that help.”
“We are an attractive target for hackers as we possess a lot of sensitive information. If we were to be attacked, it could have significant consequences with data be ending up in the wrong hands. We feel safer knowing that a team of security experts is watching our infrastructure 24/7.”
“WithSecure protects more than 850,000 accounts across 4,000 clubs and societies, and transactions of over €175 million to date. The system needs to be watertight; when it comes to the elite level, keeping data safe is just another thing to worry about.”
Less stress. Stronger security. Here’s how they did it.
