After more than a year of beta testing, 8G Firewall is ready for use on production sites. So you can benefit from the powerful protection provided by the latest evolution of the nG Firewall (aka nG Blacklist). The 8G Firewall offers lightweight, server-level protection against a wide range of malicious requests, bad bots, automated attacks, spam, and many other types of threats and nonsense. 8G is a lightweight (only 17KB) strong firewall that provides site security and peace of mind. Plus, 8G is open source and 100% free for everyone :)

About 8G Firewall
The 8G Firewall is a carefully crafted set of security rules for Apache and Nginx servers. It can be applied via your site’s public root .htaccess file, or added via server configuration. Once added, 8G provides powerful server-level protection against a wide range of malicious requests, bad bots, automated attacks, spam, and many other types of threats and nonsense. It’s a lightweight (only 17KB) strong firewall that improves site security and peace of mind.
8G Firewall builds on 7G, optimizing scope with performance while minimizing false positives. Learn more about nG-series firewall, including 8G and all the details:

Thanks for the new Firewall Jeff!
Is it possible to copy the txt.file to my .htaccess when using Nginx? Just like I would using Apache?
No because Nginx doesn’t support Apache/.htaccess.
Of course ;-) So sorry for the confusion. I ment to ask for Litespeed servers NOT Nginx.
Then yes, if it supports Apache/.htaccess then it should work fine. Of course always test well before going live.
Great, thx!
Hi Jeff! I was hoping that you could help me out. I just added Solid Security AND your 8G code to my website. Solid Security does a scan twice a day and I believe the bot is being blocked. I am getting an email saying “site_verification_failed.connection_error”.
Is there a way to whitelist an IP, or do you think it is something else?
If I read it correctly, robots.txt is on the blocking URI pattern? Why?
That is incorrect,
/robots.txtis never blocked by any of my firewalls.
