Forms protected

Detection engine

Fourteen signals. One decision. Milliseconds.

No single check decides whether a submission is spam. Every request is scored across independent signals at once, then weighed together โ€” so a real visitor sails through while a bot has to defeat all of them at the same time.

Reputation & network

Where the request really comes from โ€” long before it touches your form.

  • Datacenter vs residential origin
  • Public spam blocklists (DNSBL)
  • Custom IP blocklists
  • Submission rate & frequency

Email validation

Whether the address behind the submission is real and reachable.

  • Domain can actually receive mail
  • Disposable & throwaway addresses
  • Structural heuristics

Content analysis

What the submission actually says, analysed locally โ€” no third-party AI.

  • Gibberish & machine-generated text
  • Known spam content patterns

Behavioral

How the form was filled โ€” the part bots find hardest to fake.

  • Invisible honeypot fields
  • Time-to-fill timing
  • Real keyboard & pointer interaction
  • Client signature & optional proof-of-work

Signals are scored cumulatively, not in isolation โ€” protection that adapts as spammers do.

Built on a single POST /v1/analyze call. Add a signal, tune the weighting, and every protected form benefits at once.

Built for everyone

Why Shield

Engineered for the real world

Not another reCAPTCHA. A modern engine with multi-layer detection and full transparency.

Fast response time

Redis-backed engine optimized for synchronous form submission. Faster than your form's redirect.

GDPR by design

No cookies, no tracking pixels, no fingerprinting. Email and IP stored as SHA-256 hashes. 30-day retention.

Multi-layer detection

Honeypot + rate limiting + IP reputation + disposable email + ASN + content analysis. Stacked scoring, not single-shot.

Cross-tenant intelligence

When a spammer hits one site, every site in the network is protected. Network effect scales with each new customer.

Full audit log

Every decision logged with score, rule breakdown, and reasoning. Investigate any block, restore any false positive.

Honest pricing

Fair plans from free to enterprise. No hidden seat fees, no API rate-limit shakedowns, no Big Tech revenue model.

How it works

Three steps. No magic.

1

Install the plugin or call the API

WordPress users: install the free plugin, paste your API key. Developers: one POST /v1/analyze with form data.

2

Engine scores in milliseconds

Multi-layer rules run in parallel: honeypot, rate limit, IP reputation, disposable email, content patterns. Each rule contributes to a 0-100 score.

3

Decide based on your thresholds

Configure per-site thresholds: block above 70, challenge above 40, allow below. You stay in control of false positive trade-offs.

Pricing

Honest plans, no surprises
