Security Risks: The <iframe> tag can expose forms to attacks like Cross-Site Scripting (XSS) and clickjacking, compromising user data and form integrity.
Data Privacy Compliance: Embedding forms on external sites can hinder compliance with data protection laws (e.g., GDPR, HIPAA), making it harder to ensure secure data handling.
User Experience: embedded forms can lead to poor design consistency, mobile responsiveness issues, and conflicts with the host site's styling, degrading the user experience.
Support Challenges: Troubleshooting is harder when forms are embedded elsewhere, as issues may arise from either the external site or the SaaS tool.
