Akismet (Preemium)

Akismet is yet another plugin developed by the people behind WordPress (Matt and his team at Automattic). It is one of the default plugins of WordPress that comes with every new WordPress core installation. It is basically an anti-spam plugin which checks all comments and filters out the spammy comments.

The plugin provides a status history for each comment so that you can learn which comments were found spammy by Akismet or the moderator. Moderators also can view the number of approved comments for each user, see the URLs in the comment body and remove the suspicious links.

The plugin is free for the personal site and blogs while you have to subscribe to its monthly plans for commercial sites. The premium plans provide advanced security solution besides spam protection.

It is a useful plugin to protect your WP security.
