Tamnoon, a leader in Managed Cloud Security Remediation, announced it has raised $12 million in Series A funding. The funding round was led by cybersecurity investment firm [Bright Pixel Capital (formerly Sonae IM), with participation by new investors Blu Ventures and Mindset Ventures and existing investors Merlin Ventures, Secret Chord Ventures, Inner Loop Capital, and Elron Ventures.
Tamnoon is the first/only hybrid human-AI managed service developed from the ground up specifically for cloud security remediation. Launched by cloud security and AI/ML industry veterans, Tamnoon combines artificial intelligence (AI) with human intelligence (HI) to provide an expert-guided remediation process at scale for the cloud that does not break business operations. Tamnoon reduces cloud exposures and enhances cloud security by optimizing pre- and post-deployment prioritization, triage, remediation, and prevention processes, contributing to a more robust and mature Continuous Threat Exposure Management (CTEM) program.
As organizations are shifting to the cloud and investing in visibility and cloud risk detection solutions—such as cloud-native application protection platforms (CNAPP) and cloud security posture management (CSPM)—they demand a similarly scalable approach to the remediation process. And on average, it takes 145 hours (about six days) for a cloud security alert to be resolved; nearly half of the organizations see up to 50 misconfigurations per day, and almost half of all cyber security professionals cite a lack of qualified staff as the most significant challenge when protecting cloud workloads. Even though pure auto-remediation is appealing, poorly implemented automation can do more harm than good; modifying complex cloud environments in production without proper oversight can cause operational outages. That’s why studies show that only 9% of cloud misconfigurations are fixed in real-time with automation today.
Tamnoon customers have seen significant improvements in their cloud security operations, with a 90% reduction in critical cloud threat exposure within the first 90 days of service. They invest just 10% of the resources they would typically need using traditional professional services.
This new funding round 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. And 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 will utilize the funds to accelerate the product roadmap, expand the partnership ecosystem, and drive innovation in managed cloud security remediation. One of the company’s latest patent-pending innovations for proactive cloud exposure management (Tamnoon Prevent) is the first in the industry to provide real-time prevention of cloud vulnerabilities and misconfigurations by stopping non-secure configurations created in the console from being deployed.
KEY QUOTES:
“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. 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. We are grateful to our investors, partners, and customers for supporting us in this mission.”
-Marina Segal, CEO and Co-founder of Tamnoon
“As an early investor in the high-growth MDR space, we see Tamnoon transforming cloud security in the same way MDR revolutionized the SOC. By integrating powerful AI with expert human oversight, Tamnoon ensures remediations are efficient and minimize the risk of disrupting production environments. As workloads move to the cloud and infrastructure grows more complex, visibility alone can overwhelm teams with noise. Tamnoon addresses this by streamlining prioritization and remediation, positioning itself to drive significant market impact in an era where resource efficiency is paramount. We’re excited to partner with the Tamnoon team and support their next phase of growth.”
-Marcos de Castro Osório, Investment Director at Bright Pixel
“Strengthening our cloud security posture is a key business imperative, and Tamnoon’s innovative blend of hybrid human/AI managed service has delivered real, measurable results in a fast and efficient way for our organization. With Tamnoon, we’ve been able to quickly fix misconfigurations and accelerate our cloud security maturity while ensuring operational continuity. This has allowed us to maintain high performance levels while meeting critical KPIs and SLAs.”
