SafeSquid is a content filtering proxy server. It supports 'profiled' Internet access, a browser based interface, very fast throughput, DNS caching, content caching, pre-fetching, bandwidth control, virus scanning, ICP, CARP, and ICAP clients, source, target, and time-based granular firewall style rules to allow or deny content like music, videos, Flash and Java applets, messengers, chats, cookies, ActiveX, scripts, etc., remote authentication, real-time text and image analysis for blocking pornography, and an URL filter.
Pound is a reverse HTTP proxy, load balancer, and SSL wrapper. It proxies client HTTPS requests to HTTP backend servers, distributes the requests among several servers while keeping sessions, supports HTTP/1.1 requests even if the backend server(s) are HTTP/1.0, and sanitizes requests.
DeleGate is a multi-purpose application level gateway or proxy server that mediates communication of various protocols, applying cache and conversion for mediated data, controlling access from clients, and routing toward servers. It translates protocols between clients and servers, converting between IPv4 and IPv6, applying SSL (TLS) to arbitrary protocols, merging several servers into a single server view with aliasing and filtering. It can be used as a simple origin server for some protocols (HTTP, FTP, and NNTP).
mod_auth_nufw is a Single Sign On Apache module which performs secure user identification and authentication, based on the Nufw firewalling suite. Nufw marks all connections of a network with a unique UserID. This module takes advantage of that mark and uses it to transparently identify and authenticate users requiring access to an Apache server.
Portsmith is an application-based firewall that is designed to interact with authorized users, and offers an easy-to-use browser driven interface. Portsmith's unique features include its core logic and its interface. Its logic specifies that ports are kept in a closed position until an authorized user logs into the Portsmith interface and triggers them open. When opened, the ports are only accessible from the authorized user's current IP address.
BinarySEC is an intelligent Web application firewall designed to suppress malicious traffic on Web sites and applications. Its artificial intelligence engine learns normal traffic and blocks malicious requests with very high accuracy. BinarySEC secures against a wide range of attacks, including cross-site scripting (XSS), SQL injection, command injection, PHP includes, parameter tampering, buffer overflow, directory traversal, attack obfuscation, and more. BinarySEC for Apache includes a graphical installer and a Web-based administration interface.
Proto Balance is a load balancing and traffic management system that can handle up to 10,000 concurrent connections and 20,000 downloads per second. Proto Balance is a load balancer and TCP traffic port forwarder for high availability. It features an easy-to-use Web interface that requires minimal knowledge of networking and no command-line experience. Its target audience includes enterprise cluster providers, Internet service providers, and network administrators.
NatACL is a Linux firewall group policy controller for intranets and Internet. Using a internal DHCP server, it can force users to use a DHCP client, and you can block static IPs. It will bind an IP to a MAC address and enforce this usage. You can control groups that can see each other with intranet policies, or control who has access to the Internet. It also has an option to force users to authenticate themselves over the Web before accessing the Internet.
'NTLM Authorization Proxy Server' (APS) is a proxy software that allows you to authenticate via an MS Proxy Server using the proprietary NTLM protocol. APS has the ability to behave as a standalone proxy server and authenticate HTTP clients at Web servers using the NTLM protocol. It can change arbitrary values in your client's request headers so that those requests will look like they were created by MS IE. It is written in Python 1.5.2.
