Extension Metadata

About this extension
Port Cipher is an enterprise governance layer for AI tool usage. This release ships our full feature set:

• Per-tool / per-group / per-user policy engine (block, warn, allow, alert)
• DLP across prompts, pastes, and file uploads — 42 detectors out of the box including Australian-specific patterns (TFN, Medicare, ABN, ACN, BSB, drivers licence, passport)
• File download tracking and screen-share detection on AI tool tabs
• Shadow AI discovery with operator-curated ignore lists
• Prompt-injection detection
• Per-user behavioural risk scoring
• OIDC SSO via Microsoft Entra, Okta, Google Workspace
• Compliance dashboards (SOC2, ISO 27001, PCI, GDPR)
• Tamper-resistant Ed25519-signed policy delivery
• MV2 build for Firefox compatibility — uses browser.declarativeNetRequest (Firefox 113+) for blocking, content scripts for paste/copy/file detection, and browser.identity.launchWebAuthFlow for SSO
