About Us

StrangeBee is a European cybersecurity software company specializing in Incident Response.

Founded in 2018 by the creators of TheHive and Cortex, StrangeBee was built on the success of these tools that quickly became widely adopted within the cybersecurity community. What started as open-source initiatives evolved into enterprise-grade solutions trusted by organizations worldwide.

Today, TheHive is recognized as a leading incident response platform, empowering thousands of security analysts to detect, investigate, and respond to cyber threats efficiently.

StrangeBee now operates as a fully commercial software vendor, focused on delivering robust, scalable, and continuously evolving solutions tailored to the needs of modern security teams.

Our ambition is clear: strengthen our product ecosystem, meet the fast-growing demands of the cybersecurity market, and establish StrangeBee as a global leader in incident response platforms.

We are growing fast and we’re looking for people who want to grow with us.

Why join us

At StrangeBee, you won’t just join a company, you’ll help shape a growing European cybersecurity leader.

What makes us different is not only what we build, but how we build it.

Customer Centric

Everything we do starts with impact. We build for real security teams facing real threats. We listen carefully, challenge assumptions, and aim to deeply understand the “why” behind every need. If you care about delivering meaningful value, not just shipping features, you’ll feel at home here.

Quest for Excellence

“Good enough” is not our standard. We continuously question how we work, how we collaborate, and how we improve our product. Excellence for us means rigor, accountability, and pride in craftsmanship, whether in code, sales conversations, customer support, or internal processes.

Embrace Change

Cybersecurity evolves constantly, so do we. We encourage initiative, ideas, and constructive challenge. If you see something that could be better, you’re expected to speak up and help drive improvement. Change is not something we endure; it’s something we actively shape.

We believe performance comes from trust. We foster open communication, mutual respect, and psychological safety. Everyone’s voice matters, and collaboration goes beyond titles or departments. We succeed together.

Joining StrangeBee means working in an environment where ownership is real, standards are high, and impact is visible, while being part of a team that genuinely supports each other.
