Read-only checks do not repair files. Disruptive actions require administrator confirmation; safety-sensitive workflows use verification and rollback.
Login Protection
- Progressive IP lockouts for repeated failed login attempts
- Targeted-account activity detection
- Exact-IP whitelist and blacklist
- Active lockout management and manual unlock
- Security event logging
- Configurable client IP detection, including Cloudflare support
- Compatibility warnings for overlapping login-protection plugins
Safe Login URL
Securizer can provide a custom login path and hide normal anonymous access to wp-login.php and wp-admin. The new route is verified before the default route is hidden, and the previous configuration is restored if verification fails. An emergency recovery constant is available if access problems occur.
WordPress Hardening
Hardening controls cover XML-RPC and pingbacks, generator exposure, author enumeration, REST API user exposure, the file editor, Application Passwords, security headers, directory listing and public access to PHP-like files inside uploads. Potentially incompatible server-level changes are not forced automatically.
Core Integrity and Safe Repair
Core Integrity compares WordPress core files with official checksums and identifies modified files, missing official files and unexpected files inside wp-admin and wp-includes.
Scanning is read-only. For selected modified or missing files, Safe Repair downloads the matching official WordPress package, reads only selected files into memory, verifies checksums, writes them through the WordPress Filesystem API and scans again. Pre-repair contents remain in memory for rollback if verification fails. Unexpected files are reported and not deleted.
Diagnostics and Safe File Protection
Diagnostics checks security configuration, public exposure, HTTPS/SSL behavior, headers, file/directory protection and WordPress configuration. Some checks request the site’s public URLs to verify effective behavior.
