Browser-Based GenAI Security & Real-Time Protection
See and secure every AI interaction in the browser, from chatbots to embedded features.
The Browser Security Gap
The browser is now the core workspace of the enterprise and the primary surface for employee AI use. It is where users engage with high-risk applications, from ChatGPT and Claude to embedded AI features in tools like Grammarly and Gamma, yet most organizations still lack clear visibility into what happens there.

Harmonic Security: Control AI Use in the Browser
Harmonic Security secures AI use in the browser by giving teams real-time visibility and control over how employees interact with AI tools.
It monitors prompts and data flows in context, detects sensitive or high-risk usage, and guides users before data exposure becomes an incident.
Distinguish Personal vs. Corporate Identity
Effective monitoring must differentiate between sanctioned corporate instances and risky personal accounts. Harmonic identifies the specific account type (personal vs. corporate) and subscription plan (free vs. enterprise) in use.
You can immediately spot if an employee uses a personal Gmail account to log into ChatGPT instead of your provisioned Enterprise SSO, allowing you to enforce policy without blocking the tool entirely.
Total Visibility of Enterprise AI Use
You cannot govern what you cannot see. Our browser extension inventories every AI interaction across your estate:
- Embedded AI: Detect AI features running inside sanctioned apps (e.g., Canva, Grammarly).
- Shadow AI: Identify usage of unsanctioned tools and personal accounts.
- AI Browsers: Spot and manage the use of AI browsers that evade network logs.
“Coach, Don’t Block”
Blanket blocks drive users to dangerous shadow IT. Harmonic gives you granular control to guide secure behavior.
- Nudge: Warn users when they are about to paste sensitive data.
- Justify: Ask users to give a business justification for entering sensitive data into an AI tool.
- Redirect: Steer employees from unsafe, free tools to your sanctioned, enterprise-ready alternatives.
FAQs
Quick answers about Harmonic Security
Harmonic does not rely on a fixed list or single category of AI tools. It finds AI wherever it appears and evaluates the actual data being shared, delivering controls that Netskope and Zscaler cannot match.
Harmonic uses purpose built small language models that understand user intent and sensitive data in milliseconds. This low latency analysis lets you enforce inline controls without slowing work down, rather than staying stuck in passive monitor mode.
Harmonic can be installed with a range of MDM tools, such as Kandji, Intune, or Jamf. Read more here https://docs.harmonicsecurity.app/browser-extension
