Nagomi Security

Nagomi Security provides a proactive security and threat exposure management platform that utilizes AI agents to eliminate security risks rather than just identifying them. The company was founded in January 2023 by CEO Emanuel Salmona, CPO Jonathan Meler, and CTO Shai Mendel, all veterans of Israeli military cyber units and various cybersecurity startups. Formerly known as Vena Security, the company launched its platform within six months of its formation and surpassed $1 million in annual recurring revenue (ARR) while still in stealth mode. The founders' collective experience at companies like Snyk, Claroty, and Demisto revealed a common frustration among security teams: a lack of certainty about whether their diverse security tools were effectively optimized against real-world threats. This insight led to the creation of Nagomi, which aims to solve the coordination problem between fragmented security tools. The company has secured a total of $30 million in funding over two rounds, including a $7 million seed round led by Team8 and a $23 million Series A round led by TCV, with strategic investments from CrowdStrike Falcon Fund and Okta Ventures. Nagomi's core offering is its Agentic Exposure Ops platform, which functions as a central command center for security effectiveness. It integrates with over 40 existing security technologies from vendors like CrowdStrike, Microsoft, and Okta via read-only APIs, eliminating the need for complex installations. The platform connects and analyzes data across assets, controls, threats, and vulnerabilities to provide a unified view of an organization's defense capabilities mapped against frameworks like MITRE ATT&CK. Nagomi's AI agents autonomously investigate potential risks to determine which are genuinely exploitable, route remediation tasks to the appropriate owners, and continuously verify that fixes remain effective as the environment changes. This process of investigation, remediation, and verification replaces manual efforts, reduces backlogs, and accelerates the closure of security exposures. The business model is B2B, targeting clients in North America and Europe across sectors like manufacturing, financial services, and healthcare. Notable clients include IFF, HFW, and WELL Health Technologies. Pricing is based on organization size, measured by identities rather than devices, with different modules available for asset management and threat intelligence. Nagomi has been recognized by Gartner as a Cool Vendor and a pioneer in Automated Security Control Assessment (ASCA), a technology that continuously evaluates and optimizes security controls to reduce threat exposure.
