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.

DEVCON

Bad actors exploit the digital ad ecosystem by looking legitimate to DSPs and CDNs – hiding their true colors until they’re all the way in the browser. DEVCON creates a browser firewall to establish a last line of defense, blocking malvertising after it’s revealed itself but before it can get to your site’s audience.
But in order to create that browser firewall, we have to load in the browser! Your WordPress site can add blocking across your entire site with this DEVCON plugin that injects into the head of your site. Our proprietary technology and blocking service allows us to keep an eye on any unit in the page loading third-party demand. Our script loads asynchronously and comes from the fastest geolocated CDNs to ensure low network latency.
We offer alert only service that helps you gauge the risk on your site (how much is getting through) without blocking at no cost to you.
The first thing you need to get started is a data key. <a href="https://devcondetect.com" rel="nofollow ugc">Register here</a> and then follow the installation instructions on WordPress to get set up.
