shadowscan

ShadowScan Security Link gives you ShadowScan Guard local WordPress hardening for plugin auto-updates, username enumeration reduction, version/plugin exposure reduction, sensitive-file blocking, and basic connection/self-check diagnostics.
The plugin supports dual backend pairing with both Guard and ShadowScan. Pair with Guard backend for Guard-specific features, or connect to ShadowScan Portal to sync heartbeat status and unlock managed features for sites with an active Essential or Premium plan, or an approved reviewed pricing path. Basic Hosting can stay hosting-only, while ShadowScan Guard local hardening remains available in the plugin until managed entitlements are active.
Pairing the plugin and enabling remote diagnostics each require an explicit administrator acknowledgment in WP Admin. Those checkpoints are covered by the <a href="https://shadowscan.com.au/plugin-addendum" rel="nofollow ugc">ShadowScan Plugin Addendum</a>.
ShadowScan does not install, activate, or configure third-party security tools. If another security plugin is present, the connector only records its presence as metadata.
<h3>External services</h3>
This plugin can connect to external services to sync status, process security workflows, and support optional diagnostics after an admin pairs the site to ShadowScan.

NETSENSAI Shield offers a range of security features, including:
Changing the login URL to reduce brute force attack risks.
Disabling the REST API (WP API JSON) for non-logged-in users.
Disabling XML-RPC to prevent unauthorized access.
Disabling the WordPress file editor to avoid accidental or malicious changes.
Disabling Application Passwords to block unauthorized API access.
Applying advanced HTTP security headers (e.g., HSTS, X-Frame-Options, Content-Security-Policy).
Integration with W3 Total Cache:
Permanently disable .htaccess writes by W3TC
Runtime disabling of Page Cache UI
One-time full cache flush on first admin page load
Automatic cache flush on Secure Options save
Physical cleanup and permanent disable via the W3TC API
Suppression of Site Health REST API availability notices for non-logged-in users (removes false Site Health errors while maintaining full API blocking).
In addition, the plugin provides helpful user feedback:
Email notifications when the login URL changes – sends a localized HTML email (Polish or English) with your old and new login links, change date and the plugin logo, so you remember to update your bookmarks.
Admin popup when disabling the WP API JSON – displays a friendly modal warning that disabling the REST API may break plugins like WooCommerce or contact forms. The popup includes a purchase link to upgrade to the PRO version if you need this feature without losing functionality.
Scoped styling – the custom colour for the “Save changes” button is now limited to the Secure Options page, so other admin pages keep the default WordPress look.
Promotional banner assistant – notifies administrators of summer discount codes and NETSENSAI Shield PRO features.
The free version provides both core and advanced Level 3 security functionalities. A PRO version offers extended support, additional features, and automatic protection enhancements.

NETSENSAI Shield

Hardens and protects your site by locking down login, REST API, XML‑RPC, file editor, and applying HTTP security headers.
