Table of Contents


Accessing Security Settings

  1. Open your form in the builder
  2. Click the “Security” button in the top navigation
  3. The Security modal opens with 3 tabs: Submissions, Spam Protection, and Location

Submissions Tab

Control how many times each person can submit your form. This is enforced server-side and cannot be bypassed.

Submission Options

  • One submission per person – Each person can only submit the form once. Duplicate submissions are blocked.
  • Allow multiple submissions – People can submit the form multiple times, up to a limit you set.

Maximum Submissions

When allowing multiple submissions, you can set the maximum number of times each person can submit. Set to 0 for unlimited submissions.


Spam Protection Tab

Block suspicious traffic and protect against fraudulent submissions.

Protection Levels

  • Off – No spam protection. Accept all submissions.
  • On (Recommended) – Blocks Tor users and known abusers. Balanced protection that works for most forms.
  • Strict – Maximum protection. Blocks VPNs, proxies, Tor, and data center traffic.

What Each Level Blocks

On (Recommended):

  • Tor users – Anonymous network often used for spam
  • Known abusers – IPs flagged for malicious activity

Strict:

  • Everything from “On” level
  • VPN users – Virtual private networks
  • Proxy servers – Traffic routing services
  • Data centers – Non-residential IP addresses

Warning: Strict mode may block legitimate users on corporate networks or using privacy tools.

Allow VPN Connections

When using “Off” or “On” protection levels, you can toggle whether to allow VPN connections. This option is not available in Strict mode (VPNs are always blocked).


Location Tab

Control which countries and U.S. states can access your form. Requires Ultimate plan.

Country Restrictions

  • Allow all countries – No geographic restrictions
  • Only allow specific countries – Form only accessible from selected countries
  • Block specific countries – Form accessible everywhere except selected countries

U.S. State Restrictions

When the United States is included in your allowed countries, you can further restrict by state:

  • Allow all states – No state-level restrictions
  • Allow some states – Only selected U.S. states can access
  • Exclude some states – All states except selected ones can access
