Watchdog Security Lite — Powered by Lumiverse Nexus

Watchdog Security Lite is the free WordPress security edition powered by the Lumiverse Nexus ecosystem. It brings together active request protection, local malware scanning, vulnerability intelligence, official-file integrity checks, login protection and WooCommerce-aware controls in one security-focused dashboard.

Watchdog Lite is designed to provide useful protection without turning every unusual request into an attack claim. Detection, observation and enforcement are kept distinct wherever possible so site owners can understand what the plugin actually saw and what it actually restricted.

Core security features

• Traffic Shield Lite – conservative request-abuse protection for suspicious scanning, repeated hostile traffic and selected XML-RPC pressure.
• Login Guard – login abuse protection with lockout controls designed to avoid treating ordinary mistakes as attacks.
• Malware Scanner – local PHP/file scanning with high-confidence signatures, changed-file-first routine scanning and MU-plugin coverage.
• Vulnerability Watch Lite – checks installed WordPress, plugin and theme versions against Nexus vulnerability intelligence and provides severity plus update guidance.
• Official File Integrity – compares WordPress core and supported WordPress.org components with official checksums or packages.
• Safe Core Repair – manually restores verified modified or missing WordPress core files after creating a protected restore point.
• Optional administrator TOTP 2FA – authenticator-app protection and one-time recovery codes, configured separately by each administrator.
• Security Incident Inbox – groups related security activity into readable incidents.
• Site Change Watch Lite – records important administrator, plugin, theme and risky file changes.
• WP-Cron persistence checks – highlights high-confidence suspicious scheduled-task patterns and risky combinations.
• Watchdog Live Pulse – a real-data visual view of recent traffic, bots and protection activity. It does not invent attack events.
• Weekly Security Digest – optional once-weekly email summarizing protection activity, scan coverage and important security health signals.
• Nexus Threat Network Lite – optional shared threat intelligence with selected high-confidence signal contribution and privacy-preserving aggregate security telemetry.

WooCommerce-aware protection

WooCommerce stores receive cart, wishlist, catalog, checkout, AJAX and crawler traffic that should not all be treated as ordinary page requests.
Watchdog Lite includes WooCommerce Bot Cart Guard Lite. When enabled, crawler-claimed and obvious automation may still access public pages while supported cart, wishlist or remove-item mutations are neutralized before they create unwanted shopping state.
Normal shoppers, logged-in users and ordinary browser traffic are not handled by this crawler/automation rule.
For business sites and stores that need earlier request containment, advanced WooCommerce resource protection, deeper incident investigation, richer Threat Network intelligence and recovery workflows, see Lumiverse Nexus PRO.

Optional TOTP two-factor authentication

TOTP 2FA is optional and configured separately by each administrator. It protects the standard WordPress administrator login; API, XML-RPC and application-password authentication remain separate controls. Watchdog Lite does not force 2FA after installation, after an update or when Recommended Local Protection is applied.
The feature works with standard time-based authenticator applications, stores the secret locally and provides one-time recovery codes. Administrators should keep recovery codes in a secure location.

Nexus Threat Network Lite

Nexus Threat Network Lite is disabled by default.

When an administrator enables Threat Intelligence Lite, the site joins the Nexus Threat Network participation model. While enabled, the site can:

• receive compact shared threat intelligence;
• contribute selected, high-confidence security signals used to strengthen network intelligence.

Selected verified security signals are a separate part of Threat Network participation and may include the attacking public IP address together with limited security metadata such as event type, rule reference, confidence, request category, aggregated observation count, plugin version and a pseudonymous contributor credential.

Disabling Threat Intelligence Lite stops Threat Network participation and discards unsent aggregate telemetry. Confirmed-match blocking remains a separate protection choice.

External Services

Watchdog Security Lite performs routine malware/file scanning locally. Website files and file contents are not uploaded for routine malware scanning.

Lumiverse Nexus services

Watchdog Lite may communicate with services under: lumiversenexus.com

These services provide malware-signature updates, vulnerability intelligence and Nexus Threat Network functions.

Signature and vulnerability intelligence: requests may include normal HTTPS connection information and the public component information needed to retrieve the relevant intelligence. Installed component versions are evaluated locally. Website files, page content, usernames, passwords, customer data and order data are not uploaded for these checks.
Threat Network participation: While enabled, selected high-confidence verified security signals may include an attacking public IP address plus limited security metadata such as event type, rule reference, confidence, request category, aggregated observation count, plugin version and a pseudonymous contributor credential.

Threat Network registration does not require a customer name, email address, WordPress username, license key or site URL.
