Yodabytz just added a Web Application Firewall script to his portfolio.
SecuNX is an automated security solution for Nginx servers, designed to enhance your website’s protection by managing IP blocklists and whitelists. It fetches malicious IP addresses from trusted sources, updates your Nginx configuration automatically, and ensures that trusted IPs are never inadvertently blocked. Additionally, SecuNX provides a custom 403 error page to inform blocked users appropriately.
