PixieBrix

SquareX detects attacks in the browser. PixieBrix prevents risky actions in the work.

PixieBrix transforms how your team works - right inside the browser. Automate tasks, trigger workflows, and embed custom UI elements into any web app. No context switching, no data risk, no backend engineering.

PixieBrix has helped solve one of our hardest operational problems - streamlining communication & product updates across support teams. Tracking and keeping everyone in the loop has yielded better agent performance, customer satisfaction & taken a huge burden off management.

How does PixieBrix compare to SquareX?

SquareX is built for browser detection and response - spotting phishing, malicious files, and identity attacks as they unfold (it's now part of Zscaler following the February 2026 acquisition). PixieBrix is built for the everyday risks that aren't attacks at all: an agent pasting a card number into a chat, sensitive data copied to the wrong place, a record changed without a reason. It blocks, masks, and prompts right inside the page - and automates the workflow around it. If you're evaluating SquareX for browser threats, PixieBrix covers the other side of browser risk: guardrails and guidance for the people doing the work.

How does PixieBrix work?
