Nexura Security — Malware Scanner, Firewall, 2FA & WordPress Security

Yes, 100% free. All core security features — malware scanning, file integrity monitoring, 2FA, brute-force protection, WAF, hardening, database scanning, and the revolutionary Reinfection Guard — are completely free with no usage limits. The Pro version adds advanced automation (like scheduled scans, AI-assisted code fixing, and AST tokenizer analysis) for enterprise sites.

This is one of the biggest frustrations for WordPress site owners. When you delete an infected file, malware often returns within hours or days because hackers plant stealth persistence mechanisms across your site:

• Hidden Must-Use (MU) Plugins that execute before normal plugins load.
• Rogue Drop-ins (like fake advanced-cache.php or db.php) that hijack requests.
• Malicious WP-Cron Scheduled Tasks that silently download fresh malware payloads in the background.
• Executable PHP scripts hidden inside deep subdirectories of /wp-content/uploads/.
• Database Options Injections in wp_options containing base64-encoded reinfection scripts.
• Modified server configs (.htaccess, .user.ini, or wp-config.php). Nexura Security's Reinfection Guard is specifically engineered to analyze and uncover all these persistence vectors so you can eradicate malware at its root.

1. Install & Activate: Install Nexura Security from your WordPress dashboard or upload the zip file.
2. Run a Deep Malware Scan: Go to Nexura Security → Malware Scanner and click "Start Scan". Nexura will check all core files, plugins, themes, and uploads.
3. One-Click Cleanup: Review detected threats and click "Clean" to remove malicious backdoors and web shells.
4. Run Reinfection Guard: Navigate to Reinfection Guard to audit crons, drop-ins, and persistence vectors to ensure malware cannot regenerate.
5. Lock Down with 2FA & Hardening: Enable Two-Factor Authentication (2FA) and One-Click Security Hardening to block future brute-force and exploit attempts.

If you see the red Google Chrome warning "The site ahead contains harmful programs", "Deceptive site ahead", or "The site ahead contains malware", your website has been compromised with malware or phishing scripts and blacklisted by Google Safe Browsing. To fix this issue:

1. Scan your site: Run a Nexura Security deep malware scan to find hidden backdoors, malicious redirects, and infected files.
2. Clean the malware: Remove all detected threats using our one-click cleanup tool.
3. Check Reinfection Guard: Neutralize any scheduled crons or persistence scripts that might reinstall the malware.
4. Request a Review: Go to Google Search Console, navigate to "Security Issues", and submit a review request. The warning is usually lifted within 24-72 hours. Nexura's built-in Google Safe Browsing Check lets you monitor your blacklist status directly from your WordPress dashboard.

If you see "This site may be hacked" next to your domain in Google Search results, Google has detected SEO spam (like the Japanese keyword hack or Pharma hack) on your site. Nexura Security's deep scanner can find and remove these hidden spam injections so you can request a review and restore your SEO rankings.

Yes. The built-in malware scanner detects backdoors, obfuscated code, web shells, and known malware patterns. You can remove detected threats with a single click. For fully automated, zero-touch cleanup and AST tokenization, upgrade to Nexura Security Pro.

No. Nexura Security uses a micro-batching architecture that runs all scans in small, non-blocking chunks in the background. It utilizes lightweight background scanning, even during a full site scan of 50,000+ files.

Nexura Security offers comparable malware scanning, firewall, 2FA, and brute-force protection — but with a significantly lighter performance footprint. Unlike Wordfence, Nexura Security does not insert blocking rows into your database during normal operation, and its WAF uses auto_prepend_file to intercept threats at the PHP level before WordPress even loads.

Sucuri's core plugin on WordPress.org primarily offers activity auditing and basic hardening. Nexura Security provides a more complete free feature set including a built-in malware scanner, 2FA, brute-force protection, and automated security alert emails — all in one plugin.

Yes. The free version fully protects WooCommerce sites. The Pro version adds WooCommerce-specific protections including anti-card-testing on checkout pages and customer account takeover prevention.

Only when you explicitly enable a cloud feature such as Threat Intelligence, Pwned Passwords, or Safe Browsing. All external connections are fully documented in the Third-Party Services section above. By default, everything runs on your own server.

Yes. Nexura Security is compatible with all major caching plugins including WP Rocket, W3 Total Cache, LiteSpeed Cache, and WP Super Cache. The WAF and scanner operate at the PHP level and do not interfere with caching behavior.

Yes. Nexura Security is fully compatible with Cloudflare proxied sites. The WAF and brute-force protection correctly identify and handle traffic passing through Cloudflare.

PHP 7.4 or higher is required. PHP 8.1+ is recommended for the best performance.

Yes. Nexura Security can be network-activated on WordPress Multisite installations.

Yes. There are no restrictions on the number of sites you can protect with the free version.
