- **Policy Engine & Real-Time Enforcement** — Configurable rules that monitor, warn on, or block agent actions in the browser - covering refund/discount integrity, data exfiltration detection, PII/payment-card masking, snooping detection, and account-takeover prevention.
- **Audit & Monitoring Tools** — Real-time activity logs, screen monitoring, transaction matching across tabs, and anomaly detection that give customer-ops and compliance teams browser-level insight without heavy endpoint installs.
- **AI Engagement / Intelligent Automation** — Integrations with LLMs (OpenAI, Anthropic Claude) plus AI-powered decision trees and automation templates that guide support agents through workflows and surface recommendations in context.
- **Agent Browser Shield** — A free, source-available Chromium MV3 extension that sanitizes web pages before AI browsing agents read them - stripping page chrome, masking PII, suppressing hidden text, and blocking prompt injection, dark patterns, and context pollution. Integrates with agent runtimes like Browser Use and Browserbase.
