Hiawatha started in January 2002 as a very small web server, suitable for servers with old hardware. It was written originally for Internet servers in student houses in Delft of South Holland, the Netherlands. Because the author was a computer science student with special interest in IT security, all sorts of experimental security features were included. This resulted in a web server with many interesting security features which have proven useful. The author has said "I know for a long time that vulnerabilities [exist in other web servers] . [One thing] that bothers me: the runtime of a CGI. A CGI process [under other web servers] can run forever. A single CGI script can DoS a webserver. A system administrator is needed to kill the script. And what about a client [or hacker] that keeps on guessing passwords for HTTP authentication? These kind of issues inspired me to create Hiawatha, with settings for maximum request sending time, maximum CGI run time, client banning, etc. Features that, in my opinion, every daemon should have."
The January 2009 edition of Linux Magazine contained an article about the Hiawatha web server.

Hiawatha web server implements all important functions of a modern web server, such as:
- CGI and load balancing FastCGI support
- Large file support
- Reverse proxy functionality
- Chroot support
- URL toolkit which support URL rewriting
- SSL and TLS support
- Basic and digest HTTP authentication
- Upload speed control by traffic shaping
- Internal file caching
- IPv6 support
- HTTP compression using gzip
- Virtual hosting
- Support for WebDAV applications
- Support for Server Name Indication included in v8.6
Hiawatha has many security features that no other web server has, like preventing SQL-injection, cross-site scripting (XSS), Cross-site request forgery (CSRF) prevention, denial-of-service protection, control external image linking, banning of potential hackers and limiting the runtime of CGI applications. The author worked on RFC3546 support, but "the OpenSSL documentation [on this subject] is just extremely poor" so progress was difficult. Although, RFC3546 support has been included since v8.6 version which is developed with PolarSSLv1.2 .
Although security is the main focus, Hiawatha is also doing quite well in terms of speed and performance. According to a performance test carried out by an independent researcher (SaltwaterC), Hiawatha beats others for static content. Hiawatha supports load-balanced FastCGI and has its own PHP-FastCGI utility, which makes it fast and scalable for handling dynamic content.
Usage statistics of Hiawatha web server is often underestimated. Due to its security traits, Hiawatha web server may reject unknown web crawlers not from web search engines, which may include some from web survey agencies.
