Choosing the right software
Start with the threat you need to address: malicious login attempts, vulnerable code, unwanted file changes or application-layer attacks. A security plugin is one part of maintenance, alongside supported PHP, updates and separate backups. Review scan overhead and alert handling before enabling overlapping protection tools; a directory listing cannot certify that a site is secure.
This shortlist covers 5 currently listed WordPress options selected from 71 catalog records with supported evidence for this use case. Each included record has an official directory URL, a recent metadata check and a recorded upstream update within two years. The selection prioritizes a matching stated purpose, then reported adoption as a tie-breaker. It is not a hands-on performance ranking or a security endorsement. The snapshot was prepared on 2026-10-02.

Compatibility comparison: 4 distinct prerequisite statements are recorded across this shortlist. WordPress 4.7 / PHP 7.0; WordPress 6.6 / PHP 7.4; WordPress 7.0 / PHP 7.4; WordPress 5.0 / PHP. Match these minimum requirements to your actual PHP and WordPress versions, then test the specific workflow on a copy of your site. A minimum version is not a promise that every theme, extension or newer runtime combination works. Missing integration evidence should remain a question for the developer.
Before choosing, use the linked product records to check current prerequisites and source timestamps. Ask the developer about edition-specific capabilities, update support and any external service account needed. Source metadata helps create a practical shortlist, but deployment quality still depends on your configuration, content and integrations. No price or feature should be treated as verified unless its source is recorded.
