WP Lighthouse is the only WordPress security and performance plugin you need.

WordPress Security

Lighthouse gives your WordPress site a hardened security posture out of the box — no complicated configuration, no separate security plugin required.

• • Lighthouse Firewall is a powerful web firewall that protects your website from hackers, attacks, and other threats. It will protect your website from SQL injection attacks, XSS vulnerabilities, proxy visitors, spam, and many other types of threats.
  • Lighthouse Firewall uses an intelligent algorithm (similar to the ones used by major industry companies) to detect all known hacker attacks as well as new unknown threats using code recognition and patterns and automatically blocks them.
  • Lighthouse Firewall blocks many bad bots and crawlers that will waste your website bandwidth. Every visitor’s response headers will be checked, and if there are suspicious patterns, their access to the website will be denied.
  • Lighthouse Firewall helps you to block and redirect users (IP addresses), IP ranges, operating systems, browsers, Internet Service Providers (ISPs), and referrers.
  • Auto-banning automatically blocks attackers and threats. Each threat and attack is logged into the database, so you can view them later.

WordPress Performance

Based on each user's requirements, Lighthouse allows for the removal of new and non-optional features and queries, as well as the disabling of various native requests and functionality. Lighthouse also helps with security by adding several rules for HTTP(S) requests, XML-RPC, and malicious requests.

• • Tons of options, clean and professional design, no advertisements, and developer-oriented
  • Lazy loading to speed up page loads
  • Works in Chrome, Firefox, Edge, Safari, Opera, and Brave.
  • Removes WordPress bloat
  • Optimization presets
  • Offers useful data for educated, informed decisions
  • Does not conflict with caching plugins
  • Does not conflict with other performance plugins
  • Does not conflict with Cloudflare
  • Gets automatic lifetime updates
  • Minification, theme tweaks, media & storage options
  • Debugging tools

WordPress Persistent Object Cache

SQLite3-backed persistent object cache — a zero-dependency, file-based caching layer that eliminates redundant database queries on every page load.

• • Faster page loads—Cached data is served from a local SQLite file with sub-millisecond reads, reducing load on your MySQL server and speeding up every page.
  • Zero external dependencies—no Redis, no Memcached, no additional server software. SQLite3 is bundled with PHP — it just works.
  • One-click install and remove—Deploy or remove the object-cache.php drop-in directly from Settings > Lighthouse > Cache. No FTP, no SSH, no manual file copying.
  • Real-time statistics—A WordPress dashboard widget shows live hit/miss ratios, total cached keys, database size, and cache efficiency so you always know what’s happening.
  • Automatic housekeeping—An hourly background task purges expired entries, keeping the cache lean without any manual intervention. Production-ready — Uses SQLite WAL mode, memory-mapped I/O, and prepared statements for safe concurrent access and maximum throughput.

SpeedFactor

Test your site for performance and security using the SpeedFactor module — unlimited automated page speed monitoring and  tracking. Track your website performance over time and keep track of how it’s doing, and get tips on what to improve — no coding required.

When you measure your site, Lighthouse’s SpeedFactor module uses a bespoke method. A custom-tailored Simulated User Monitoring audit, testing for raw data related to page load timing, such as connection, redirection, Time to First Byte, and more. SpeedFactor will then save all this data and show its progress in a daily chart. This is useful for event monitoring and for experimenting with various site features, content management systems, cache systems, database queries, and resource requests.

Volt: WordPress Multi-Site Management

Volt turns your WordPress dashboard into a central command center for every website you manage. Monitor performance, track pending updates, and push bulk updates across all your sites — without ever leaving a single admin panel.

• • Performance—Time to First Byte (TTFB) for each site, color-coded so slow responders stand out immediately.
    System stack—WordPress, PHP, and MySQL versions displayed as visual badges so you can spot outdated environments instantly.
  • Storage—Disk usage and database size per site.
  • Security posture—Flags for file editing, XML-RPC status, and open user registration.
  • Cloudflare detection—Know which sites are behind Cloudflare at a glance.
  • Bulk Updates—Stop logging into each site individually to run updates. Volt lets you select any combination of sites and push plugin, theme, or WordPress core updates in one operation — with real-time progress tracking and detailed error reporting when a site needs attention.
  • Weekly Email Reports—Opt in to a Monday-morning digest that tells you exactly what needs your attention across your entire portfolio: how many plugin, theme, and core updates are pending, which sites need them, and a TTFB performance snapshot for each site — all in one clean, scannable email.
  • Add Sites in Seconds—Paste a list of URLs to bulk-import dozens of sites at once (with optional API keys), or add them one at a time through a simple form. Volt detects duplicates automatically and normalizes URLs for you. Each site communicates securely via REST API and a per-site API key — no shared passwords, no direct database access.
  • Built for Agencies and Freelancers—Whether you manage 5 client sites or 500, Volt gives you a single place to answer the questions that matter: Which sites are falling behind on updates? Which ones are slow? Which ones need attention this week? — and then act on the answers without switching tabs.
