Protect Your Forms from Spam and Abuse

CAPTCHA, rate limiting, password protection, and more. Keep your forms secure and your data clean.

Open forms attract spam. Without protection, public forms can see 30-50% spam submissions. FormFlux security features (CAPTCHA, rate limiting, honeypots) typically reduce spam to under 5% of submissions.

Defense in Depth

Multiple layers of protection work together. CAPTCHA blocks 90-95% of bot submissions. Honeypot fields catch another 3-4%. Rate limiting prevents the remaining abuse attempts. Combined, these reduce spam from 30-50% down to under 5%.

Key Benefits

  • Block spam submissions
  • Rate limit abusive users
  • Password protect sensitive forms
  • CAPTCHA for bot prevention
  • Honeypot fields for invisible protection
