Firewall Extension 

The Firewall extension protects your TYPO3 website against unwanted traffic, bots, and attacks. It blocks or limits requests based on IP address, path, headers, or other patterns, and bans clients after repeated abuse.

The extension is built on the phirewall package and adds everything you need in TYPO3: the request middleware, a backend module for block patterns, bans and statistics, ready-made rule presets, and dashboard widgets.
