We Make Protecting ChatGPT and Codex Simple
Employees use ChatGPT and Codex for their daily tasks across the business. They've become the primary interfaces through which work gets done. It's a powerful shift for employee productivity, but it creates an entirely new set of security and governance challenges.
Harmonic Security makes it simple to understand exactly how your company is using ChatGPT and Codex, and provides context-aware guardrails to protect sensitive information and govern the actions of agents.

Understand Exactly How ChatGPT and Codex are Used
Discover ChatGPT and Codex usage across all surfaces that employees access it. Monitor usage even when employees use free or personal plans and set plan-specific policies.
Understand how employees use each tool (down to the task level), including which use cases lead to the riskiest behaviors and which are driving productivity.
Protect Sensitive Information in Context
Ensure employees never share information they shouldn't with ChatGPT or Codex. Harmonic Security's models are able to read through conversations just like a human would and understand what is sensitive or not in context.
Deliver inline controls across the web and desktop with clear explanations for employees of what triggers each warning or interventation.


Govern Agents Without Interrupting Workflows
Monitor what tools Codex and ChatGPT agents are connecting to and what actions are being taken.
When agents attempt actions that are not permitted, Harmonic intervenes in real time and explains exactly why an action is being prevented without stopping the workflow, so both humans and agents remain on task.

Quick answers about Harmonic Security
The OpenAI compliance platform can provide valuable logging and insights, but it only works when users are signed into the enterprise account, and it provides no inline guardrails to prevent bad things from happening before the fact. It is also completely blind to all usage of non-OpenAI tools.
EDR is designed to monitor processes running on the endpoint and detect malware. Crowdstrike and other vendors have minimal visibility into what's being done by employees within AI tools on the desktop. They'll know that an application is being run, and they could block it entirely, but they are unable to provide the task level intelligence and granular guardrails needed to safely use AI.
We provide discovery, monitoring, and inline guardrails across ChatGPT and Codex on the web, on the desktop, and within command line interfaces. We also provide discovery and monitoring for any calls to OpenAI APIs from from scripts or other applications.
