Protect your websites with AbyssGuard


If you operate any type of feature rich website you know how hard it could be to get the right balance of security and end userabyssguard-screen functionality. AbyssGuard can be setup to the level of security you need for your website and is not intrusive. Abyssguard works silently in the background of your websites without your users even knowing it is there. Seamlessly scanning, protecting and logging all traffic hitting your website. I have been using AbyssGuard for over six months and I can only say great things about it. Prior to using Abyssguard I had been using ZBlock which worked ok, but have since moved on to AbyssGuard which provides more features. You can try AbyssGuard out for yourself, best of all it is still free for now. At some point in the future it most likely will become a paid service.

If you have ever manually set up a WordPress site, you can easily setup AbyssGuard. You just create an SQL database in you control panel, create a user and password for that database with all privileges, input that and configure the information in the Abyssguard config file, set all folder permissions, then run the script by going to its web address. Detailed setup information here.

AbyssGuard is a web site protection system that offers capable threat prevention against hackers, spammers, script kiddies, bad bots and bandwidth killing scrapers. It analyzes the behavior of your visitors and access attempts looking for malicious activity. After initial traffic analysis, your website is only served to the legitimate traffic. Verified visitors will be cached for a short period of time so as to not keep triggering further traffic analysis. If AbyssGuard detects malicious behavior, the offender will be banned for your specified amount of time and your web resources will not be served, thus saving bandwidth and server resources. The indexoffenders will not be checked multiple times as the Client has its own Cache and Banlist. Abyssguard utilizes the Project Honeypot spam signatures in addition to Abyssguard’s user generated signatures for blocking. All offending IP addresses are being cached at the AbyssGuard Server and if enough different people report them for malicious activity they will be blacklisted for a short period of time. I have not noticed any noticeable speed degradation while using AbyssGuard.

AbyssGuard does not protect your web server, just your web sites. AbyssGuard is ideal for webmasters that own several web sites on the same server as it can be enabled on all of them with single centralized instance and common log. Once the main client side script is installed, it is as simple as placing a single line of PHP code at the top of a page in your websites.

AbyssGuard consists of Server and Client side. The Client side will observe the visits to the websites you wish to protect and will send information to the Server for analysis. The information sent to the Server is as follows:

  • Your Settings values in order to know what to analyze

A summary of AbyssGuard functions include the following:
