Opportify

<p><strong>Opportify Fraud Protection</strong> stops fake sign-ups, form spam, bot submissions, and fraudulent leads on every WordPress form. It works silently, in real time, with no friction for real users.</p>
<p><iframe loading="lazy" title="Opportify&apos;s Fraud Protection" src="https://player.vimeo.com/video/1179038954?dnt=1&app_id=122963" width="750" height="422" frameborder="0" allow="autoplay; fullscreen; picture-in-picture; clipboard-write; encrypted-media; web-share" referrerpolicy="strict-origin-when-cross-origin"></iframe></p>
<p>Unlike CAPTCHA, which frustrates genuine visitors and is easily bypassed by modern bots, Opportify works invisibly in the background. It analyzes over 100 signals per submission: behavioral patterns, device fingerprints, email risk, IP reputation, and VPN or proxy detection. Each submission is scored so you can automatically allow, flag, or block it.</p>
<h4>Who This Is For</h4>
<p><strong>WordPress site owners and marketers</strong> tired of spam flooding their contact forms, fake leads cluttering their CRM, or bots registering fake accounts.</p>
<p><strong>WooCommerce store owners</strong> who need to stop fraudulent checkouts, fake account registrations, and disposable email sign-ups before they cause damage.</p>
<p><strong>Developers and agencies</strong> who want an API-backed, code-configurable fraud layer with per-integration control, risk metadata on entries, and support for version-controlled config files.</p>
<p><strong>Security and operations teams</strong> who need explainable risk scores with a per-submission breakdown of every contributing factor.</p>
<h4>Why Not Just Use CAPTCHA?</h4>
<p>CAPTCHA hurts conversion rates for real users and is routinely bypassed by modern bots. Opportify takes a different approach: it observes behavioral signals before the form is even submitted, analyzes every signal at the moment of submission, and delivers a risk verdict your site can act on. All of this happens in under a second, with no puzzles, no friction, and no false positives for legitimate visitors.</p>
<h4>What It Detects</h4>
<ul>
<li>Disposable and temporary email addresses</li>
<li>High-risk and known-fraud email domains</li>
<li>VPN, proxy, Tor exit node, and datacenter IP addresses</li>
<li>Bot and automated browser behavior</li>
<li>Device fingerprint anomalies</li>
<li>Geographic and velocity anomalies</li>
<li>Mismatched or suspicious behavioral signals</li>
</ul>
<h4>Risk Levels</h4>
<p>Every submission receives a score and one of five plain-language risk levels:</p>
<ul>
<li><strong>Lowest</strong> and <strong>Low</strong>: Healthy submissions from genuine users with clean signals.</li>
<li><strong>Medium</strong>: Worth a closer look, but not necessarily fraudulent.</li>
<li><strong>High</strong> and <strong>Highest</strong>: Risky submissions. Likely spam, bots, or fraud. Block or flag automatically.</li>
</ul>
<h4>Per-Integration Actions</h4>
<p>For each supported form plugin, you can independently configure what happens at each risk level:</p>
<ul>
<li><strong>Allow</strong>: The submission proceeds normally.</li>
<li><strong>Flag</strong>: The submission proceeds, but the risk score, level, and contributing factors are saved as metadata visible in WP Admin.</li>
<li><strong>Block</strong>: The submission is rejected with a customizable error message.</li>
</ul>

</ul>
<h4>How It Works</h4>
<ol>
<li>The Opportify JS SDK loads silently in your site header. It collects behavioral signals such as mouse movement, keystroke timing, scroll depth, and device entropy, then generates a session fingerprint.</li>
<li>When a form is submitted, the SDK attaches a behavioral token to the submission automatically.</li>
<li>The Opportify PHP SDK sends the submission to the Fraud Protection API for analysis: email risk, IP intelligence, device signals, behavioral correlation, and more.</li>
<li>Based on your configured thresholds, the plugin allows, flags, or blocks the submission instantly.</li>
</ol>
<p>No CAPTCHA. No user friction. No separate configuration per form.</p>
<h4>Reports Dashboard</h4>
<p>The plugin’s Reports page gives you a clear view of your site’s submission health:</p>
<ul>
<li><strong>Health checklist</strong>: confirms your API keys, connection status, and active integrations at a glance</li>
<li><strong>Risk distribution chart</strong>: donut chart showing the split between Healthy, Caution, and Risky submissions</li>
<li><strong>Submissions by integration</strong>: bar chart showing which forms receive the most risk</li>
<li><strong>Submission log</strong>: filterable table with date, integration, email, IP, score, risk level, action taken, and contributing factors</li>
<li><strong>Dashboard link</strong>: access detailed trend analysis and advanced filters in the Opportify Dashboard</li>
</ul>
<h4>External Services</h4>
<p>This plugin connects to two Opportify services:</p>
<ul>
<li><strong>Fraud Protection API</strong> (<code>https://api.opportify.ai</code>): analyzes each submission server-side using your private API key. Data sent: email address, IP address, and behavioral signals from the JS SDK.</li>
<li><strong>JS SDK CDN</strong> (<code>https://cdn.opportify.ai</code>): loads the client-side behavioral telemetry script using your public key. This script collects behavioral signals (typing cadence, mouse movement, device entropy, and automation indicators) that are correlated server-side with the fraud analysis. The plugin automatically fetches the latest script version from the CDN manifest and injects it into your site header.</li>
</ul>
