Hourly Limit on Outgoing Emails
Caps how many emails the site can send per hour and stops the rest, which protects your mail account and domain reputation if a form or plugin is abused to send spam.
Limit Contact Form 7 Submissions per Visitor
Allows only a few Contact Form 7 submissions per IP address each hour and treats the rest as spam, which stops bots and angry repeat senders flooding your inbox.
Limit Fluent Forms Submissions per Visitor
Allows only a few Fluent Forms submissions per IP address each hour and shows a polite message after that, which stops flooding and repeated spam.
Limit Gravity Forms Entries per IP Address
Stops a visitor from sending more than a few Gravity Forms entries per hour from the same IP address, with a polite message, to block flooding and repeat spam.
Limit How Many Files Non-Administrators Can Upload per Hour
Caps uploads at 30 files per hour for each user who is not an administrator, which limits the damage a compromised author account or a buggy front-end upload form can do.
Limit Password Reset Requests
Allows only a few password reset requests per hour from the same IP address, which stops reset-email flooding.
Limit WPForms Submissions per Visitor
Allows only a few WPForms submissions per IP address each hour and blocks the rest with a polite message, to stop flooding and repeat spam.
Rate-Limit Site Searches
Limits how many searches one visitor can run per minute and answers the rest with "429 Too Many Requests", protecting your database from search floods.
Rate-Limit the REST API for Visitors
Limits how many REST API requests a logged-out visitor can make per minute and answers "429 Too Many Requests" beyond that, slowing scrapers and scanners.
Stricter Comment Flood Protection
Requires a longer pause between two comments from the same person, 60 seconds instead of WordPress's 15, to slow down comment bursts.
