Description
LanceDesk Form Guard protects contact and registration forms from spam using a two-layer defense system:
- Layer 1 — Heuristics: Fast deterministic checks for BBCode injection, link stuffing, honeypot fields, and too-fast submissions.
- Layer 2 — AI Analysis: Optional semantic spam classification via Groq, OpenAI, or Anthropic.
Supports WPForms, Contact Form 7, Gravity Forms, Quform, and Ninja Forms. Logs blocked and quarantined submissions with hashed IP and email values for privacy.
External services
This plugin optionally connects to third-party AI APIs to classify form submissions for spam. No submission text is sent until AI analysis is enabled, the privacy acknowledgment is checked in Settings, and at least one provider is enabled with an API key.

FAQ
-
Which form plugins are supported?
-
WPForms, Contact Form 7, Gravity Forms, Quform, and Ninja Forms are supported when installed and active.
-
You can configure fail-open (allow submission when heuristics pass) or fail-closed behavior in Protection Rules.
-
Is submission data sent to third parties?
-
When Layer 2 AI analysis is enabled and you have acknowledged the privacy notice and configured a provider with an API key, truncated form field text may be sent to that provider for spam classification. Heuristics-only protection stays on your site. See External services below.
-
Does this plugin use the WordPress AI Client?
-
Not in this release. Form Guard uses site-owner API keys with a multi-provider fallback (Groq, OpenAI, Anthropic) so spam classification works on WordPress 6.4+ without requiring core AI Client setup. We may evaluate WordPress AI Client integration in a future release.
