Acessium Guard by Renan

AI usage guardrails for the workforce: detects and masks sensitive data before it is sent to AI apps.

About this extension

Acessium Guard is the enterprise extension of the Acessium Guard platform, installed and configured by the company's IT team. It works on the AI apps used at work (ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek, Grok, Poe) and:

inspects, BEFORE sending, the typed text and attached files (TXT, PDF, DOCX and other text formats) for sensitive data: Brazilian CPF/CNPJ, credit cards, keys and secrets, source code, confidential terms defined by the company;
applies the policy defined by the manager: allow, warn or block, per rule and per department;
records only metadata and a MASKED excerpt of what was detected. The raw prompt or file content never leaves the browser.

The extension does not work on its own: it requires the organization's Acessium Guard server and an enrollment key. It does not collect browsing outside the configured AI apps.
