dotDefender secures websites against a broad range of HTTP-based attacks, including Session attacks (e.g.
Denial of Service), Web application attacks (e.g. SQL injection, Cross-site scripting, and known attack signatures), as well as requests originating from known attack sources ( e.g. spammer bots and compromised servers). dotDefender quickly installs on the Web server along with a predefined, configurable rule-base - enabling it to secure the Web environment from the moment it is deployed, with virtually no administrator intervention. 15-day evaluation period version is available for download.
