Tamnoon raises $12M Series A for cloud security remediation platform
The Israeli startup has developed a hybrid human-AI managed service that reduces cloud exposures and enhances cloud security by optimizing prioritization, triage, remediation, and prevention processes for both pre and post deployment.
Tamnoon, which develops a managed cloud security remediation platform, announced on Wednesday that it has raised $12 million in Series A funding. The round was led by cybersecurity investment firm Bright Pixel Capital (formerly Sonae IM), with participation by new investors Blu Ventures and Mindset Ventures as well as existing investors Merlin Ventures, Secret Chord Ventures, Inner Loop Capital, and Elron Ventures.
Tamnoon has developed a hybrid human-AI managed service specifically for cloud security remediation. Its platform reduces cloud exposures and enhances cloud security by optimizing prioritization, triage, remediation, and prevention processes for both pre and post deployment, contributing to a more robust and mature Continuous Threat Exposure Management (CTEM) program.
Tamonoon was founded in 2022 by Marina Segal (CEO), Idan Perez (CTO), and Zohar Alon (Chairman). All three were members of Dome9 Security which was sold to Check Point in 2018. The company currently employs 20 people split between Israel and the U.S.
This new investment brings Tamnoon's total funding to over $18 million, just under one year after completing its Seed round led by Merlin Ventures and Secret Chord Ventures. Since then, Tamnoon has more than doubled its customer base and now serves organizations across various industries throughout North America, including insurance, entertainment, healthcare, retail, and professional services. Tamnoon integrates with all leading cloud CNAPP/CSPM solutions including Wiz, Orca Security, AWS Security Hub, Check Point CloudGuard, Palo Alto Networks Prisma Cloud, CrowdStrike, Microsoft Defender for Cloud, Google Cloud Security Command Center and Oracle Cloud Guard.
“Neither fully automated nor human-driven cloud remediation approaches alone can address the complexity of cloud security posture management programs. The idea of relying entirely on automation in remediation is not feasible. It is too risky to apply in critical production environments without human oversight,” said Marina Segal, CEO and Co-founder of Tamnoon. “Tamnoon combines our powerful, purpose-built AI technology for cloud remediation, guided by cloud security experts, to safely reduce critical threat exposures to near zero in just months after deployment.”
Shay Michel, Managing Partner at Merlin Ventures, noted: “One of the biggest challenges in adopting security technologies is the lack of teams and resources to manage them effectively. Tamnoon enables companies to scale rapidly, allowing entrepreneurs and R&D teams to easily decide which technologies to adopt and at what scale to grow.”
