Mesh Security, the company behind what it calls the world’s first Cybersecurity Mesh Architecture (CSMA) platform, announced Wednesday that it has raised $12 million in a Series A funding round led by Lobby Capital, with participation from S Ventures (SentinelOne’s corporate venture arm) and Bright Pixel Capital.
Mesh’s platform aims to serve as the execution layer for modern security operations, helping organizations unify a patchwork of cybersecurity tools into a single interoperable system that reduces exposure and strengthens resilience at scale. The company said the funds will be used to enhance autonomous capabilities, expand the platform’s system‑level remediation abilities and scale sales and support for growing enterprise demand.
Over the past decade, enterprises have invested heavily in best‑of‑breed tools across identity, endpoints, data, cloud, software as a service, networks and continuous integration/continuous delivery environments. While individual tools have improved, security as a system has not kept pace, Mesh said, leading to a proliferation of disconnected tools, fragmented data and operational gaps no single product can fully manage.
Mesh is designed to address that structural gap not by replacing existing tools but by operating above them as an execution layer, unifying visibility, context and control without requiring agents or a rip‑and‑replace strategy. The company said its platform enables organizations to move from human‑driven security operations to system‑driven exposure elimination.
The startup’s platform is built to put the theoretical concept of Cybersecurity Mesh Architecture — as outlined by research firm Gartner — into real‑world practice. While CSMA has emerged as an industry aspiration, many organizations struggle to execute it effectively. Mesh positions itself as the missing execution layer, enabling cross‑domain visibility and control across business units, subsidiaries, teams and environments without disrupting existing security investments.
“For years, enterprise security has accumulated tools and data, but it never built an execution layer that connects them into a single operating model,” said Netanel (Neo) Azoulay, CEO and co‑founder of Mesh Security. “Mesh was built to realize Cybersecurity Mesh by unifying context and control across best-of-breed environments, so security finally works as one system, without vendor lock-in.”
Market trends are driving interest in the approach, with security leaders facing increasing pressure from corporate boards to reduce risk, demonstrate return on investment and accelerate operational capabilities. Legacy security architectures, the company said, were not designed for execution at scale, prompting a shift toward “platformization” and putting cybersecurity mesh on the agenda at the highest levels of corporate governance.
Mesh said its technology is already deployed in complex production environments, working alongside leading security platforms to enable enterprise‑wide adaptive defense. It cited collaboration with top vendors — including SentinelOne — and adoption by enterprises seeking to unlock the full value of existing security tool investments.
“Mesh provides a clear way to understand where a security program stands,” said Bradley Schaufenbuel, vice president and chief information security officer at payroll and HR firm Paychex. “It helps identify the critical gaps that actually matter and drives the process of closing them. What stands out is that it doesn’t require replacing existing tools; it’s designed to make the security stack work as one zero-trust system.”
Lobby Capital founding partner Buddy Arnheim said his firm was “thrilled to lead this investment in Mesh Security, as they pioneer the future of unified security operations and CSMA security. Mesh’s platform is uniquely positioned to help enterprises achieve true cybersecurity mesh architecture in an era of increasing complexity.”
Mesh Security is headquartered in Palo Alto with operations in Tel Aviv, Israel. The company says its platform allows enterprises to transform fragmented security stacks into real‑time, adaptive defense systems without agents or rip‑and‑replace strategies, unlocking the full value of existing security investments while reducing exposure at scale.
