Harmonic Security

Harmonic Security is an LLM Guardrails & AI Safety and generative artificial intelligence (AI) governance platform that provides visibility, semantic data classification, and real-time policy enforcement across enterprise AI usage. Delivered via endpoint agents, browser extensions, OpenTelemetry data collectors, and Model Context Protocol (MCP) gateways, the platform discovers, monitors, and controls user and autonomous agent interactions across web applications, desktop software, developer command-line interfaces (CLIs), Integrated Development Environments (IDEs), and local or cloud-hosted AI tools.

Shadow AI Discovery & Usage Intelligence (Harmonic Explore)

The platform continuously discovers and inventories official, unsanctioned, and embedded AI applications used across the enterprise workforce. Rather than relying solely on network domain tracking, Harmonic Security monitors activity directly on local endpoints and within browser sessions to map shadow AI usage on corporate and personal devices. The platform evaluates third-party vendor risk profiles—including data retention policies, training-data opt-outs, and security certifications—and categorizes raw prompt activity into functional business use cases to quantify departmental return on investment (ROI) and risk exposure.

Semantic Data Classification & Real-Time Safeguards (Harmonic Guide)

To overcome the limitations of pattern-matching Data Loss Prevention tools that generate high false-positive rates on unstructured text, Harmonic Security utilizes context-aware Small Language Models (SLMs) to evaluate the underlying intent and meaning of prompts, code submissions, and uploaded files. Operating with a vendor-stated inline latency under 200 milliseconds, the system intercepts risk-flagged requests to warn, coach, or block users directly at the point of submission, providing contextual remediation guidance tailored to specific data types, roles, and applications.

Agentic Workflow & MCP Gateway Security (Harmonic Command)

Harmonic Security extends operational controls to autonomous AI agents, multi-agent frameworks, and developer coding tools (such as Claude Code, Cursor, and Codex). Operating through a dedicated MCP Gateway, the platform intercepts tool calls, file reads, application programming interface (API) requests, and database writes executed by autonomous agents. Security administrators can configure fine-grained permissions per agent, server, and tool action to prevent unauthorized repository modifications, credential exposure, or destructive data actions.

Enterprise AI Governance, Compliance, & Privacy Controls

Harmonic Security provides audit trail logging and data residency management to support compliance with regulatory frameworks including the European Union (EU) AI Act, the General Data Protection Regulation (GDPR), and the Health Insurance Portability and Accountability Act (HIPAA). The platform incorporates privacy-by-design controls—such as automated user-name masking, data sanitization, EU regional hosting options, and the exclusion of sensitive executive departments (such as HR, Finance, and Legal) from individual behavioral reporting—to provide risk visibility without conducting workplace surveillance.

Deployment & Platform Architecture

Harmonic Security deploys across macOS, Windows, and Linux endpoints via central device management systems including Microsoft Intune, Jamf, Kandji, and Group Policy. The platform integrates with enterprise Identity Providers (IdPs)—such as Microsoft Entra ID, Okta, and Google Workspace—to enrich security events with organizational role attributes, and streams interaction logs via webhooks to Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platforms.
