Harmonic Security is a GenAI data protection AI agent offering data protection for generative AI use that prevents sensitive data leaking into AI tools. Founded in 2023 and based in London, United Kingdom, Harmonic Security helps security and privacy teams automate GenAI data protection work and get results faster.
Harmonic Security takes text and browser activity as input and produces alerts and insights. It combines large language models with task-specific AI, with the vendor managing prompts, models and updates. It connects to tools such as Microsoft 365 Copilot, Salesforce, Okta and Slack, so the agent works inside existing workflows.
Harmonic Security is built for security and privacy teams. It suits teams that want sensitive data detection and shadow AI discovery without adding headcount, while keeping people in control of review and final decisions.
Harmonic Security is often compared with Nightfall AI. Harmonic Security stands out for sensitive data detection and in-browser nudges. The right choice depends on your workflow, integrations and budget, so compare both on a real task.
