Product Decisions This Supports

Enables secure handling of user-generated HTML content (e.g., comments, forum posts, WYSIWYG editor inputs) by preventing XSS attacks while maintaining standards compliance
Eliminates need to build custom sanitization logic, reducing development time and security risks
Supports modern web standards (CSS properties, iframe attributes, PHP 8.x compatibility) ensuring compatibility with current frontend practices
Critical for compliance with OWASP security standards and reducing vulnerability exposure in applications
Ideal for roadmap items involving content moderation, user profile fields, or rich-text editing where security and standards adherence are non-negotiable

When to Consider This Package

Adopt when processing untrusted HTML from users where XSS protection is critical (e.g., CMS, social platforms, forums)
Consider when you need robust, standards-compliant filtering beyond basic regex-based approaches (which are inherently insecure)
Look elsewhere if your use case involves only trivial HTML sanitization (e.g., stripping all tags) where a simpler solution like strip_tags() suffices, though even then HTML Purifier provides more safety

For executives: "This battle-tested package eliminates critical XSS vulnerabilities in user-generated content at scale, reducing legal, reputational, and financial risks. It's a proven, low-maintenance solution that saves engineering resources while ensuring compliance with industry security standards."
For engineering: "Seamless Composer integration, customizable configurations per context (e.g., comments vs. rich-text editor), and active maintenance with PHP 8.x support. Eliminates the need for custom sanitization code, reducing technical debt and security blind spots in the data pipeline."
