CleanTalk is a cloud-based anti-spam service. Instead of using per-site CAPTCHAs or local rules, it routes spam decisions through a centralised database that learns from millions of sites at once. The trade-off is favourable: lower friction for legitimate users than a CAPTCHA, and broader pattern coverage than per-site rules.
In addition to comment and form spam, CleanTalk also ships a brute-force shield for WordPress logins and a general bot-protection layer. The footprint is small, the integration is plug-in based, and the price is low. For a typical WordPress site, it removes a specific class of nuisance traffic without adding meaningful complexity.
CleanTalk is not a security suite. It does not scan for malware, does not act as a WAF, and does not block targeted attacks. It is a spam-and-bot layer that pairs cleanly with whatever security stack you already run.

No. CleanTalk solves the spam and bot problem; it does not include a WAF or a malware scanner. It is designed to sit alongside a WordPress security tool such as Wordfence, MalCare, or Patchstack, not to replace one.
