Prism X
Protection where your employees actually use AI
Prism X integrates with the browser-based AI tools your workforce already adopted: not a theoretical list, but the chat and upload surfaces people use daily.
- ChatGPT: text, file uploads, image prompts, custom GPT interactions
- Claude: conversation input, document uploads, project context
- Gemini: text prompts, file uploads, multimodal inputs
- Microsoft Copilot: chat input, attachments, web-grounded queries
The problem
Workforce AI adoption already happened. ChatGPT, Claude, Gemini, and Copilot are open in browser tabs across the enterprise. Protection has to be where employees actually use AI, not on a theoretical list.
Capabilities
What you get with Prism X
ChatGPT (chatgpt.com)
Text input, file uploads, image generation prompts, and custom GPT interactions.
Claude (claude.ai)
Conversation input, file and document uploads, and project-context interactions.
Gemini (gemini.google.com)
Text prompts, file uploads, and multimodal inputs.
Microsoft Copilot (copilot.microsoft.com)
Chat input, file attachments, and web-grounded queries across Edge and Chrome.
DOM-binding integration
Prism X binds to chat input surfaces in the browser, not network traffic. Resilient to vendor UI updates; new AI tools that follow standard input patterns are often covered without per-site configuration.
What we don't claim
Prism X targets AI chat and upload surfaces. It is not a CASB, SWG, or general web DLP that covers every egress path. It solves the specific high-growth problem of sensitive data leaving through browser AI tools.
How it works
From instrumentation to evidence
- 1
Bind to the DOM
The extension binds to chat input surfaces in the browser DOM: text areas, rich text editors, contenteditable elements, and common accessibility roles.
- 2
Observe submit actions
When the user clicks Send, presses Enter, or triggers a submit action, Prism X intercepts before the browser dispatches the request.
- 3
Survive UI changes
The content layer monitors DOM changes for single-page apps. Vendor UI updates rarely break coverage because the integration follows standard input patterns.
What teams use it for
In production, every day
ChatGPT custom GPTs
An employee uses a custom GPT to summarize internal data. Text input, file uploads, and image-generation prompts are all in scope.
Claude project context
A user attaches documents to a Claude project. Project-context interactions and file uploads are evaluated against policy before they reach Anthropic.
New AI tool, no update needed
A team adopts a new browser-based AI assistant that uses standard text-area inputs. The existing integration model often covers it without per-site configuration.

Integration model
Why the DOM approach holds up
- Works even when vendors update their UI; the content layer monitors DOM changes for SPAs.
- Specific to AI chat and upload surfaces, not a broad web filter claiming to cover every website.
- New AI tools using standard input patterns are often compatible without extension updates.
What we don't claim
Prism X targets AI chat and upload surfaces. It is not a CASB, SWG, or general-purpose web DLP that covers every data egress path on the internet. We solve the specific, high-growth problem of sensitive data leaving through browser-based AI tools.
