Protect every human and AI browser action — without a new browser
PixieBrix deploys as a managed extension to monitor human and AI actions in any web app — including third-party sites — with full browser context that network controls miss.
Configure group policies in minutes to monitor, warn, soft-block or block actions, with built-in contact-centre and anti-fraud controls plus AI-code and low-code custom controls.
Cover refund and discount integrity, shipping and loyalty fraud, payment-card masking, and flag snooping, bulk exports and after-hours activity.
Every browser action is logged with on-screen context, backed by user risk scoring and an MCP investigation server for correlating data sets.
