7G Firewall | Perishable Press
▻https://perishablepress.com/7g-firewall
The 7G Firewall is a powerful, well-optimized set of rewrite rules that checks all URI requests against a set of carefully constructed Apache/.htaccess or Nginx directives. This happens quietly behind the scenes at the server level, which is optimal for performance because it avoids the need to load up PHP and MySQL just to block a bad request. This is one reason why securing at the server level is better than using a plugin or other PHP script.
