This plugin enhances website security by automatically identifying and blocking outdated browsers and suspicious user agents. It is designed for site administrators who need to reduce security vulnerabilities and manage bot traffic without manual intervention.

• Real-time User Agent Analysis: Sends new user agent strings to an external API to determine browser and operating system details, storing the results locally for efficiency.
• Configurable Blocking Rules: Automatically blocks access based on criteria like outdated browser versions (e.g., Chrome below version 139) or old operating systems (e.g., Windows versions prior to Windows 10).
• Bot Verification & Control: Checks if crawlers genuinely originate from major search engines like Google or Bing and blocks browsers missing critical security headers.
• Customizable Exceptions: Allows you to exclude specific user agents (like those from Mastodon) from blocking to prevent false positives and maintain accessibility.
• Integrated robots.txt Management: Provides configurable rewrite rules to serve a tailored robots.txt file, denying crawling access to unwanted bots directly.
