- **Company:** Harmonic Security, Inc
- **Location:** United States
- **Employment:** full-time
- **Work type:** remote
- **Posted:** 2026-11-09

## Job description

AI is being run everywhere, by humans and agents. Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk. We operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down. Named to the Rising in Cyber 2026 list, we’ve continued building momentum with an additional $50 million secured in Series B funding, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel. As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.

How We Work: AI-First by Design We bring the same curiosity about AI to our own work that we bring to our product. Everyone at Harmonic is expected to explore AI tools and use them thoughtfully to improve how they research, build, collaborate, and deliver results. We provide the tools and support to help you put that curiosity into practice.

## About Harmonic Security, Inc

## Company Overview
- **One-liner**: Harmonic Security provides an AI governance and control platform that gives enterprises real-time visibility and inline guardrails across browser, desktop, and AI agent surfaces to enable safe, fast AI adoption.
- **Entity Type**: Private (raised $24.5M total funding across Seed and Series A rounds)
- **Headquarters**: San Francisco, California, United States (with additional offices in London, UK)
- **Founded**: August 2023
- **Founders**: Alastair Paterson (CEO & Co-founder) and Mark Sutton (CTO & Co-founder)

## Core Business
- Primary industry: AI Governance and Security (Technology, Information and Internet)
- Target customers: Enterprise B2B, specifically security teams and IT administrators
- Mission: "To pave the way for secure AI adoption in enterprises, ensuring innovation thrives without compromise"

## Products & Services
- **Harmonic Security Platform**: A unified control plane covering four surfaces (browser extensions, desktop clients, MCP gateway, embedded AI copilots) that reads the intent and context of every AI interaction, applies policies inline in under 200 milliseconds, and coaches users in the moment without disrupting work.
- **MCP Gateway**: Governs agentic workflows at the Model Context Protocol layer, inspecting tool calls, scopes, and destructive actions even when no human is in the loop.
- **Browser Extension + Desktop Client**: Covers 1,000+ AI surfaces including ChatGPT, Claude Desktop, Cursor, Canva, Gamma, Grammarly, Google AI mode, and more. Detects sensitive data and enforces guardrails on end-to-end encrypted traffic that never passes through the corporate proxy.
- **Agent Governance**: Extends policies to autonomous AI agents that act independently, inspecting file reads, API calls, database writes, and email summaries.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total funding $24.5M; LinkedIn-estimated annual revenue of $1.0M (may be a placeholder)
- **Notable Investors/Partners**: Ten Eleven Ventures (Alex Doll, Founder), René Bonvanie, Grant Whiting, Bryan Woolgar-O'Neil
- **Growth Signals**: 
  - RSA Innovation Sandbox Finalist in 2024
  - Launched MCP Gateway in October 2025
  - Landed Series A funding (July 2024)
  - Headcount of ~55 employees with consistent hiring across SF, London, and remote US
  - SOC 2 and GDPR certified; EU AI Act alignment

## Competitive Advantages
- **Intent-based detection, not keyword/regex**: Policies fire on the intent and context of prompts and agent actions rather than string matching, reducing false positives.
- **Covers the full AI surface**: Browser, desktop, MCP, and embedded copilots — including traffic and agents that network tools cannot see.
- **Inline guardrails in <200ms**: Real-time decisions that coach users or block actions without disrupting workflow.
- **Privacy-by-design**: Employee names can be masked, HR/Finance/Ops/Founders excluded from reporting, and the dataset is sanitized and frozen. Designed to avoid becoming surveillance.
- **Rapid deployment**: Minutes via MDM (Intune, JAMF, Kandji, Group Policy) with no proxy redesign or certificate gymnastics. Full AI inventory available on day one.
- **Agent-ready**: Governs autonomous AI workflows at the MCP and tool call level, not just human prompts.

## Strategic Focus
- Scaling enterprise adoption of AI governance for both human and agentic AI use
- Deepening MCP Gateway capabilities as AI agents become more prevalent
- Growing the platform's coverage to new AI surfaces and expanding data classification
- Maintaining leadership in the emerging AI Security category through continued product innovation and market education

## Why Work Here
- **Culture**: Small, senior team operating in high-trust, high-ownership mode. Real responsibility from day one. Values include "Flourish in the Unknown" (comfort with ambiguity), "Never Full" (hunger to learn and help), and "Perfect Harmony" (collaboration and honest feedback).
- **Work Policy**: Flexible hybrid — 3 days per week in the San Francisco office for US-based roles; London team also hybrid. Remote US roles available.
- **Benefits**: Competitive pay and meaningful equity; health, dental, and vision coverage; 401k matching; flexible time off; 25 days PTO (UK); pension plan matching (UK); Cycle to Work Scheme (UK). Annual global offsites (past locations include Lisbon and Nashville).
- **Engineering Culture**: Substance over hype; psychological safety and mutual respect; decisions made quickly; feedback direct; focus on building for high-stakes environments.
- **Growth**: Shape both the product and the category in a foundational moment for AI governance.
