About Us

We Live Cyber Security.

CERTAINITY stands for security and trust—our name combines the words CERTAINty and SecurITY. As an experienced team, we provide tailored cyber security consulting, from penetration testing and incident response to compliance strategies. We help organizations strengthen their digital resilience — reliably, independently, and with deep roots in Europe. We identify critical vulnerabilities and process-related risks, develop effective security strategies, and support their implementation, guided by internationally recognized standards such as ISO/IEC 27001, NIST, and OWASP. Our pragmatic approach avoids unnecessary complexity — security should enable your business, not slow it down. As an owner-managed European company, we practice what we preach, maintaining high internal security standards and operating our own ISO/IEC 27001-certified Information Security Management System (ISMS).

Our Values

A strong company is built on strong values. These are the principles that guide everything we do.

reliable.

Our clients rely on us — and we rely on each other. Being accessible, meeting our commitments, and delivering on our promises are part of who we are. With flat hierarchies and short decision-making paths, we work efficiently, collaboratively, and with a strong focus on practical solutions.

trustworthy.

CERTAINITY was founded out of a genuine passion for cyber security — and our clients and colleagues experience that every day. We live our values, foster open communication, encourage ownership, and create an environment where trust can thrive. As a multiple-time Great Place to Work® award winner, we know that trust starts within the team — and is reflected in the quality of our work.

bespoke.

At CERTAINITY, there is no one-size-fits-all approach to cyber security. We listen, think ahead, and develop tailored solutions that truly fit — technically, organizationally, and culturally. Our experts combine deep technical expertise with the freedom to think creatively and act pragmatically. Because in an environment built on trust and personal responsibility, meaningful solutions emerge. That’s something we’re proud of — and so are our clients.
