Spam Account Defender Pro

Protect every registration. Automate the hard work.

Spam Account Defender Pro adds smart automation, verified crawler intelligence, server-load safeguards, and advanced controls to the complete free Standard edition.

Pro control for high-traffic WordPress sites

Keep the practical protection in Spam Account Defender Standard, then add the tools that help busy sites respond faster: scheduled scans, optional automatic cleanup, advanced firewall configuration, verified crawler reporting, CPU-aware operations, and exportable security history.

Spam Defender Pro

Security controls for the work that cannot wait

Keep Standard’s practical, manual protection. Add automation and more precise controls only where your site needs them.

Verified crawler intelligence

Verify trusted search crawlers by IP and domain, report their activity, and identify imposters without treating legitimate search traffic as an attack.

Automation with safeguards

Schedule scans and choose automatic cleanup only when it suits your policy. Keep Administrator accounts protected and retain manual review as the default workflow.

CPU Guard and Admin Guard

Slow risky work when server load rises, configure additional protected roles, restrict sensitive access, and retain an audit trail for security administration.

Advanced firewall and reporting

Tune advanced firewall controls, harden REST/XML-RPC registration routes, and export security activity when you need it.
