PromptShield Shadow AI Guard

Blocks public AI sites your organisation has not approved and points you to your company's protected PromptShield workspace.

PromptShield Shadow AI Guard helps organisations keep company data out of public AI chatbots. When someone opens a public AI chat or writing tool that their organisation has not approved, the extension shows a short page instead, explaining why, with a button to the company's PromptShield workspace, where approved AI models are available with sensitive data protected. The list covers about 70 widely used public AI services and is maintained with each release. For administrators: - Add your own sites to the list, or make exceptions, from the PromptShield console. - Link browsers to your organisation with enrolment codes that can be limited to an email domain, an expiry date and a number of uses. - See which public AI sites were tried, from which browser, how often and when. - Get an alert when a browser stops checking in, so a disabled or removed extension doesn't go unnoticed. - Deploy silently with Chrome Enterprise or Microsoft Edge policies. Privacy by design: the extension never reads web pages, never sees what you type, and has no content scripts. Only the blocked site's address, your browser name, the time and a count are sent, and only to your own organisation's PromptShield server. Reporting requires a PromptShield Enterprise account (https://enterprise.promptshield.live); blocking works without one.
