Mesh Security, a Palo Alto and Tel Aviv-based cybersecurity startup positioning itself as the “execution layer” for Cybersecurity Mesh Architecture (CSMA), has raised $12 million in Series A funding. The round was led by Lobby Capital, with participation from S Ventures (SentinelOne’s corporate venture arm) and Bright Pixel Capital.
The company says the funding will accelerate development of its autonomous, agentic capabilities and support expansion of sales and customer support as enterprise demand grows. Mesh’s platform is designed to sit above existing security tools and unify “visibility, context, and control” across fragmented environments, moving security operations from human-driven workflows to system-driven exposure elimination.
Mesh is targeting a common pain point in modern security programs. Over the past decade, many enterprises have assembled best-of-breed stacks spanning identity, endpoint security, data protection, cloud, SaaS, networks, and CI/CD. While those tools improved individual domains, Mesh argues that the overall security system became harder to manage, resulting in fragmented data, disjointed operations, and persistent exposure that no single product can fully address.
Rather than replacing tools, Mesh says it operates agentlessly and avoids rip-and-replace deployments. The pitch is that enterprises can transform a fragmented security stack into a single interoperable operational fabric across business units, subsidiaries, teams, and environments, while limiting vendor lock-in.
The company is aligning its strategy with CSMA, an architectural direction popularized by Gartner. Mesh claims its platform operationalizes CSMA in real-world enterprise environments by enabling cross-domain visibility and control without disrupting existing investments. The company also says it is already deployed in complex production environments and works with major security platforms, including SentinelOne.
As security leaders face increased board-level expectations to reduce risk, demonstrate ROI, and respond faster, Mesh is betting that “platformization” and mesh-based architectures will shift from concept to execution focused adoption. The company’s next phase focuses on reasoning across cross-domain attack paths and enabling system-level remediation to eliminate exposure, rather than adding more dashboards and alerts.
KEY QUOTES
“For years, enterprise security has accumulated tools and data, but it never built an execution layer that connects them into a single operating model. 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.”
Netanel (Neo) Azoulay, CEO and Co-Founder, Mesh Security
“Mesh provides a clear way to understand where a security program stands. 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.”
Bradley Schaufenbuel, VP and CISO, Paychex
“We’re 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.”
Buddy Arnheim, Founding Partner, Lobby Capital
