PIIP (PII Protection) is a plugin that automatically detects and masks personally identifiable information (PII) in WordPress comments and community plugin content before the data is saved to your database. This helps protect user privacy and ensures GDPR compliance.

Key Features

Automatic PII Detection: Intelligently detects multiple types of PII including emails, phone numbers, addresses, credit cards, SSN/My Number, passwords, API tokens, IP addresses, and hosting account IDs
Server-Side Masking: All masking happens on the server (PHP) for maximum security – cannot be bypassed by users
WordPress Core Support: Native support for WordPress comments
Community Plugin Support: Works seamlessly with wpForo, BuddyPress, bbPress, and other popular community plugins
Configurable: Choose which PII types to mask via easy-to-use settings page
Consent Opt-Out: Users can include consent phrases to skip masking when sharing personal info publicly
Presidio-Level Detection: High-accuracy detection with validation (Luhn for credit cards, check digits for My Number)
