If you're looking for quick and inexpensive Web application security, dotDefender offers protection against common threats through a software plug-in for IIS, Microsoft ISA and Apache servers.

dotDefender installed rapidly and much more easily than hardware-based Web application firewalls (see comparative review, March 2008). Since it's a plug-in, configuration and management for IIS and ISA is handled through the Microsoft Management Console. The Apache version installs as an inline module.
By default, dotDefender deployed in a protective operating mode, leaving us covered against the majority of common attacks we threw at it right out of the box.

PolicyA
Tweaking the policies to return our test websites to complete functionality took about an hour per site. Although the default policies and rules were ample to protect against all of our attacks, dotDefender required minor tuning to maintain the usability of the applications on our Web server, such as those that utilized advanced Javascript or built with older Web tools.
Policies center on patterns and signatures. Patterns define what dotDefender looks for in terms of exploits, such as buffer overflows, SQL injection, cross-site scripting, cookie manipulation, etc. Each pattern includes two sub-menus: user defined, where custom rules can be created, and best practices, which includes a check box list of standard defenses/mitigations against known exploits.
Signatures are regularly updated by dotDefender and include a blacklist of compromised/hacked servers, anti-proxy protection, worms, bad user agents, spammer crawlers and MPack protection against infected websites.
Security profiles with unique policy settings can be assigned to different websites hosted on the same server.
