Real-time data protection and governance for AI-native environments

Technology, Information and Internet San Francisco, California 51–200 employees Founded 2023 Privately Held

Harmonic Security operates a data protection platform built with Rust and C++ for endpoint-level visibility across browsers, MCPs, and desktop environments. The tech stack reveals a security-first engineering approach: they're shipping low-level agent code (Rust/C++) while layering on orchestration (Tines, MCP integration) and sales velocity tooling (HubSpot, Gong, ZoomInfo). Hiring is senior-heavy (13 of 18 open roles) split evenly between engineering and sales, with infrastructure (Terraform, AWS ECS, GitLab CI/CD) and go-to-market motion both under active scaling.
