dotDefender

DotDefender is a comprehensive software tool that serves as a security solution for websites, offering protection against a diverse range of HTTP-based threats. This web application firewall functions to prevent attackers from exploiting vulnerabilities and engaging in cybercriminal activities like session attacks, DoS attacks, and web application attacks such as SQL injection and cross-site scripting.

The software features an advanced signature database, which identifies and blocks traffic associated with known attack signatures. Additionally, it can also detect and block requests originating from malicious sources, thus protecting websites from attackers who attempt to exploit vulnerabilities in web servers.

DotDefender is designed for use on web servers running Apache 1.3x or Apache 2.0x on a Linux operating system. It also requires the installation of Perl interpreter to function effectively.

However, the software has some limitations, including a 15-day trial period. Overall, DotDefender is an excellent security tool that provides robust protection for websites against HTTP-based attacks, making it a valuable asset for website owners who prioritize security.
