Charles is an HTTP proxy / Reverse Proxy / HTTP monitor that enables a developer to view all of the HTTP traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).
Charles can act as a man-in-the-middle for HTTP/SSL communication, enabling you to debug the content of your HTTPS sessions.
Charles simulates modem speeds by effectively throttling your bandwidth and introducing latency, so that you can experience an entire website as a modem user might (bandwidth simulator).
Charles is especially useful for Macromedia Flash developers as you can view the contents of LoadVariables, LoadMovie and XML loads. More about Charles and Flash.
Charles is also useful for XML development in web browsers, such as AJAX (Asynchronous Javascript and XML) and XMLHTTP, as it enables you to see the actual XML that is flowing between the client and the server.
Main features:
- Cookies are shown in the HTTP headers, so you can see exactly what cookies you are sending and receiving.
- Every request and response is recorded in Charles. Redirects that are often too quick to see when testing with a web browser can be seen in Charles. Requests from applications other than your web browser (such as Flash movies) can also be seen.
- Request and response sizes are shown in Charles, so you can see how big each request was.
- Assets loaded from an HTML page are recorded so that you can see how many images etc are loaded by a page, and where from.
- All files can be viewed, including JavaScript files, CSS files, HTML files etc.
- Mirror all responses to disk, recording your session.
- Blacklist sites so that requests are blocked.
- See the results of caching by seeing cached responses (304 Not Modified), and requests containing last modified dates (IfModifiedSince).
- Disable caching by removing cache related headers from requests and responses as they pass through Charles, ensuring that you are always requesting the latest file.
- See whether a cache has served your request by looking for cache-hit HTTP headers.
- View encrypted HTTPS traffic in plain text. Enables you to view requests and responses in plain text even when communicating with an SSL secured web server.
- Reveal unexpected requests, such as typos and 404s.
- View requested images.
- Bandwidth Throttle your web connection to a specified bytes/second speed, and millisecond latency. This enables you to simulate modem conditions on a high speed internet connection (bandwidth simulator)
- Spoof DNS name to ip mappings so that you can test a domain name before it has gone live. Very useful for testing your virtual hosting.
- Export to CSV all of the summary data captured by Charles for analysis and reporting in Excel
- Reverse proxy creates ports on the localhost that act as regular HTTP servers, but forward all requests to a specified web server.
- HTTP 1.1 support - including keep-alive, chunking and content-encodings including gzip, compress and deflate.
- External proxy support - configure an proxy for Charles to use to access the Internet
- NTLM authentication support (Windows NT Challenge Response Authentication / Integrated Windows Authentication)
- Automatic configuration of Windows Internet Proxy settings.
- Search all headers and bodies for keywords.
- Port forwarding support, allows any protocol to be forwarded by Charles and debugged.
- Unicode and other charset encoding/decoding support.
- AJAX debugging (Asynchronous Javascript and XML) and XMLHTTP debugging
- AMF parsing to help debug Flash Remoting
- Firefox proxy autoconfiguration
- Automatic Update Checking

ufdbGuard is a URL filter. The URL filter blocks access to sets of Web sites on the Internet and is designed to be used with the popular Web proxy server, Squid.
ufdbGuard uses a fast algorithm that does 25,000 URL verifications/sec on an Intel 2.8 GHz CPU.
The facts
Internet misuse by employees is as much as 2,5 hours per week (Ernst & Young)
75% of organizations are hit by viruses, spyware, or other malicious applications
20% of at-work internet users admit to visit X-rated websites from work

NullBound Malware Prevention System project is an enterprise level anti-spyware solution that is capable of protecting thousands of PCs with a single installation.

The system runs passively on the network which allows for no integration changes or downtime.

Our technology allows you to protect an entire enterprise network by simply plugging in a computer. No end-user software, no proxy servers. Its that simple.

The NullBound Malware Prevention System utilizes advanced filtering seen nowhere else. We can not only detect, but completely block spyware from entering your network while only watching the traffic. This is the way it was designed, this is the way it works best.

Malware Detection

Our solution attacks the malware threat from the network level. It has an advanced method of being able to analyze real-time web traffic and compare it to an extensive database to detect malware. If an alert is triggered the connection between the client and the offending host is severed immediately, all while being transparent to the end user. Not
only is it capable of stopping malware from known black-listed sites, it is capable of stopping malware from unknown sites. This alone makes it more valuable than any black-list available.

Complete Transparency

Our unique solution does not just simply
block known offending websites. Instead we specifically look for the malware itself. This form of detection has many major benefits. Even when browsing unknown websites, the malware is still unable to be transferred onto the end users system. The user is completely
unaware.

Network Integration

Integrating new solutions into existing
networks can be a cumbersome task. Our
technology is like no other available in the market. With it we take network integration to a new level, being able to not only detect but to block malware while only “watching” the network traffic. Your existing network and traffic flow does not have to be proxied, passed through, filtered, firewalled, routed or impeded on in any way. Because of this it can not impede on network performance and can not be a point of failure.

Real World Success

Our real world testing has shown outstanding results, blocking 98% of malware before it ever reaches the end user. With our incredible transparency, end users are not even aware of the malware being blocked.
