Predax

<p><strong>Predax Security</strong> connects your WordPress site to the Predax threat intelligence API to detect and block malicious traffic in real time — once the site administrator has enabled a protection preset.</p>
<p>After you complete setup and pick a protection preset (or enable individual protections from Settings), visitor IPs are checked against a continuously-updated database of known VPN providers, open proxies, Tor exit nodes, datacenter ranges, and web crawlers. High-risk IPs are blocked before they can log in, register, post comments, or browse your site.</p>
<p>On a fresh install the plugin is <strong>off by default</strong> — no visitor data is sent anywhere until you explicitly enable a protection via the setup wizard or the Settings → Protection tab.</p>
<h4>Key Features</h4>
<ul>
<li><strong>Security Dashboard</strong> — real-time overview with blocking activity chart, threat breakdown, top targeted paths, protection status, and country analysis</li>
<li><strong>Real-time VPN/Proxy/Tor/Datacenter detection</strong> — checks every visitor against live threat intelligence</li>
<li><strong>Risk score thresholds</strong> — block IPs above a configurable risk score (0–100)</li>
<li><strong>Country geo-blocking</strong> — block or allow specific countries and regions</li>
<li><strong>Login protection</strong> — block high-risk IPs from attempting to log in</li>
<li><strong>Registration protection</strong> — stop fraudulent account creation</li>
<li><strong>Comment protection</strong> — block spam and bot comments at source</li>
<li><strong>Visitor protection</strong> — optionally check all page visitors (with 1-hour caching to minimise API calls)</li>
<li><strong>XML-RPC & REST API protection</strong> — extend blocking to XML-RPC calls and REST API requests</li>
<li><strong>Disposable email blocking</strong> — reject registrations using throwaway email services</li>
<li><strong>Custom block page</strong> — show a branded 403 page instead of the default WordPress error</li>
<li><strong>Whitelist/blacklist</strong> — override decisions for individual IPs or CIDR ranges</li>
<li><strong>Threat log</strong> — view and export all blocked events with IP, reason, and timestamp</li>
<li><strong>Event tracking</strong> — log successful checks for audit and analytics</li>
<li><strong>Settings import/export</strong> — back up and restore your configuration as a JSON file</li>

<h4>How It Works</h4>
<ol>
<li>You install the plugin, enter an API key, and pick a protection preset during the Setup Wizard (or enable individual protections from Settings → Protection). This is the explicit opt-in — no data leaves the site until you do this.</li>
<li>A visitor makes a request to your site.</li>
<li>Predax checks their IP against the threat intelligence API (results cached for 1 hour per IP).</li>
<li>If the risk score exceeds your threshold, the visitor is blocked with a configurable message.</li>
<li>All block events are logged in the WordPress database for review.</li>
</ol>
<h4>WP-CLI Commands</h4>
<pre><code>wp ipsentry status — show current configuration and threat counts
wp ipsentry test-ip <ip> — run a live API check on any IP
wp ipsentry whitelist add <ip> — add an IP or CIDR to the whitelist
wp ipsentry whitelist remove <ip> — remove from whitelist
wp ipsentry blacklist add <ip> — add an IP or CIDR to the blacklist
wp ipsentry log --limit=20 — view recent threat log entries
</code></pre>
<h3>Third Party Services</h3>
<p>This plugin connects to external services. By installing and activating this plugin you agree to the terms of each service you enable.</p>
<h4>Predax API</h4>
<p>This plugin transmits visitor IP addresses to the <strong>Predax API</strong> (https://predax.io) for real-time threat detection and risk scoring.</p>
<p><strong>What is sent:</strong> The visitor’s IP address, and optionally their timezone (when timezone mismatch detection is enabled and visitor protection is active).<br />
<strong>When it is sent:</strong> On each page load, login attempt, registration, or comment submission, subject to your configured protection settings. Results are cached for 1 hour so repeat visits by the same IP do not generate additional API calls.<br />
<strong>Who operates the service:</strong> Predax (predax.io)<br />
<strong>Terms of Service:</strong> https://predax.io/terms<br />
<strong>Privacy Policy:</strong> https://predax.io/privacy</p>
<h4>Community Threat Network (opt-in, disabled by default)</h4>
<p>The Community Threat Network is <strong>opt-in and disabled by default</strong>. No block or monitor events are sent to the community network unless you enable it yourself in <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Predax Security <span aria-hidden="true" class="wp-exclude-emoji">→</span> Advanced</strong>.</p>
<p>When — and only when — you explicitly enable it, anonymised block and monitor events (containing: IP address, action taken, block reason, country code, and risk score) are sent to the Predax API at predax.io. This data is used to build a shared threat database that improves detection accuracy for all sites in the network. You can turn community reporting back off at any time in the same settings screen.</p>
<h4>Google reCAPTCHA</h4>
<p>When reCAPTCHA v3 is enabled (Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Protection <span aria-hidden="true" class="wp-exclude-emoji">→</span> reCAPTCHA), this plugin loads the reCAPTCHA script from <strong>google.com</strong> and sends form submission tokens to <strong>google.com/recaptcha</strong> for verification. Google may collect data according to their privacy policy. You must provide your own reCAPTCHA site key and secret key.</p>
<p><strong>Google Privacy Policy:</strong> https://policies.google.com/privacy<br />
<strong>reCAPTCHA Terms:</strong> https://policies.google.com/terms</p>
<h4>Browser Fingerprinting</h4>
<p>When browser fingerprint scoring is enabled (Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Protection <span aria-hidden="true" class="wp-exclude-emoji">→</span> Fingerprint Scoring), this plugin collects screen resolution, timezone, platform string, WebGL renderer, and plugin count from the visitor’s browser on the login page. Fingerprint data is used locally to score bot likelihood and is stored in WordPress only while the login form is being submitted, then discarded. The visitor’s timezone may be included in the API request to detect timezone mismatch when that feature is enabled.</p>
<h4>Cookies set by this plugin</h4>
<p>All cookies set by this plugin are functional service cookies, not tracking cookies, and are only written when the relevant feature is explicitly enabled by the site administrator:</p>
<ul>
<li><code>ipsentry_tz</code> — carries the visitor’s browser timezone to the Predax API when timezone-mismatch detection is active. Written from <code>ipsentry-tz.js</code> on the front-end. Expires after 24 hours. <code>SameSite=Lax</code>. Only set when an API key is configured AND visitor or login protection is enabled.</li>
<li><code>ips_jsc</code> — JavaScript challenge solve token. Written from <code>js-challenge.js</code> when a visitor passes the challenge. Expires after 24 hours. <code>SameSite=Lax</code>. Only set when the JavaScript Challenge feature is enabled.</li>
</ul>
<p>No tracking or advertising cookies are written by this plugin.</p>
<p>By activating this plugin and entering an API key, you agree to the Predax Terms of Service and Privacy Policy. You are responsible for ensuring your use of visitor IP data complies with applicable privacy laws (GDPR, CCPA, etc.) and your own site’s privacy policy.</p>

<h4>The proxycheck.io API</h4>
<p>This Plugin can be used without a proxycheck.io API key, but it will be limited to 100 daily queries to the API. To enhance the capabilities, you can obtain a free API key from proxycheck.io, which allows for 1,000 free daily queries, making it suitable for small WordPress sites.</p>
<p>Here’s an overview of the free and paid API options:</p>
<ul>
<li>Without an API key (100 queries/day)</li>
<li>With a free API key (1,000 queries/day – ideal for small sites)</li>
<li>With a paid API key (10,000 to over 10 million queries/day)</li>
</ul>
<p>Your API key can be used across all of your sites and apps, you only need a proxycheck.io plan that fits your overall needs.</p>
<h4>User IP Logging Feature</h4>
<p>Proxy & VPN Blocker allows for local logging of user registration IP addresses. The IP addresses are displayed next to each user in the Users list and on their profile pages, visible to administrators. The Plugin also logs the most recent login IP address for each user, which is also displayed in the User’s list and profile page, with the IP address linked to the proxycheck.io Threats page.</p>
<h4>Caching Plugin Notice</h4>
<p>If you’re using caching plugins (like WP Rocket or WP Super Cache), IP-based page blocking might not function correctly due to static caching. A DONOTCACHEPAGE option is available to help mitigate this issue.</p>
<h4>Privacy & GDPR Compliance</h4>
<p>To check IP addresses, the plugin sends them to the proxycheck.io API. No personally identifiable information (PII) beyond the IP is transmitted. For details, refer to proxycheck.io’s <a href="https://proxycheck.io/privacy" rel="nofollow ugc">privacy notice</a> and <a href="https://proxycheck.io/gdpr" rel="nofollow ugc">GDPR Compliance</a> for further information.</p>
