At Siemba, we believe security should be a catalyst for innovation, not a barrier to it. Our mission is to move the industry beyond reactive defense toward a future of Preemptive Security.

Featured across multiple Gartner® Hype Cycle reports and recognized as a Global Top 250 MSSP, Siemba is building a next-generation platform ecosystem that helps organizations continuously discover, validate, and remediate risks before attackers can exploit them.

Our platform suite powers a Continuous Threat Exposure Management (CTEM) approach to security. It includes GenPT, our AI-native security platform for one-click visibility and autonomous testing; GenVA for continuous vulnerability assessment; EASM (External Attack Surface Management) for discovering and monitoring internet-facing assets; and PTaaS (Penetration Testing as a Service) that combines expert-led testing with continuous validation.

From Big 4 consulting firms and global government agencies to fast-growing technology companies, organizations trust Siemba to deliver the continuous visibility and resilience required in today’s threat landscape.

At Siemba, you will work with passionate security researchers, engineers, and innovators who are redefining offensive security and shaping the future of proactive cybersecurity.
