SmartField vs Session Replay Masking
A direct comparison of SmartField and Session Replay Field Masking for protecting sensitive form data.
Session Replay Field Masking
Hotjar and FullStory offer masking options. But masking is opt-in, often misconfigured, and doesn't protect from XSS.
// With Session Replay Field Masking:
document.querySelector('input').value
// "SensitiveData123" ← readable
SmartField
SmartField protects by default. No configuration needed. Works against session replay, XSS, extensions, and bots simultaneously.
// With SmartField:
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6..." ← AES-256 encrypted
