Astaro Security Gateway (formerly Astaro Security Linux) is an all-in-one network security gateway that includes a firewall, intrusion protection, antivirus, spam protection, URL filtering, and a VPN gateway. Features include a modern packet filter, intrusion detection and prevention, portscan detection, application control, content filtering, virus detection for email and Web traffic, profile handling, L2TP, IPSec, SSL, and PPTP VPN tunneling, spam blocking, proxies for HTTPS, HTTP, FTP, POP3, SMTP, DNS, VoIP, SOCKS, and Ident, logging, and reporting. It supports Ethernet, VLAN, PPP, PPPoE, PPPoA, Cable Modem, IPv6, QoS, Link Aggregation, and WAN-Uplink-Load balancing in routing, and bridge mode. The WebAdmin GUI, Install Wizard, Change Tracking, Printable Configuration, and Up2Date service make it easy to install, manage, and maintain.
Rspamd is an anti-spam system designed to work faster than SpamAssassin by using the event model and various optimizations. Its most important features include regexp and Lua rules for filtering different parts of messages, a number of built-in functions for analyzing messages, fuzzy hash support, SURBL filters, email and character table support, a control interface for remote managing and stats gathering, a Lua plugin system, statistics support (OSB/Bayes), and an AJAX-based Web interface.
CacheGuard Appliance is an all-in-one OS appliance providing firewall, antivirus, caching, compression, bandwidth allocation, load balancing, reverse and forward proxy, high availability, Web application firewall, URL guarding, and more. It can be purchased as an OS to install on your server, as an OS to run in a virtual machine, or as a hardware appliance.
Clement is an email server application. Its main function is to block unwanted mail (spam) as soon as possible in the email exchange process. It accepts or rejects email while the SMTP session, initiated by the email sender, is still pending, accepting legitimate email messages without the need to return an error status to non-existent or "borrowed" return address later. Clement can operate in two modes, either as a standard MTA (as sendmail, Postfix, Exim, Exchange, etc.) to store email in the recipient's own area, or to transmit the mail to an another SMTP server acting as smart spam filtering device. Each email domain name Clement knows about can be treated in one of these two modes depending on the group to which the domain name has been set. Each message is verified by a virus scanner (ClamAV) while the SMTP connection is still open, but the refusal of mail and the reason for refusal is notified to the actual sender. Mail management is done via a Web interface and can be delegated to three administrative levels (Root-Admin, Group-Admin, Domain-Admin). Standard users can access their own logs (sent email status, email rejected, quarantined email, etc.). With this interface, the user can handle the rejection and acceptance of mail. Users who are level "Admin" can access the session logs (via the Web interface). Clement uses a SQL database (PostgreSQL, MySQL) to store and manage logs, user profiles, and dynamic management of directives concerning the sender-receiver relationship.
ufdbGuard is a URL filter. The URL filter blocks access to sets of Web sites and cooperates with the Squid proxy. It integrates with LDAP, Kerberos, Active Directory, MySQL, and others to define different ploicies for different groups of users. ufdbGuard also enforces SafeSearch for many search engines, blocks Skype, UltraSurf, Tor, unsafe HTTPS sites, and dynamically detects proxy tunnels. The multi-threaded daemon uses a fast algorithm that does 50,000 URL verifications per second on an Intel Core 2 Duo (Conroe) at 2.4 GHz.
Jaro Mail is an integrated suite of interoperable tools for GNU/Linux and Apple/OS X to manage email communication in a private way, without relying on online services (in fact, encouraging users to store email locally). It mainly features a system for mailinglist filtering, address-book integrated whitelisting, strong encryption and anonymous remailing, long-term email storage and archiving with functions for fast search and usage statistics. To accomplish all that, it makes use of solid Unix tools like Mutt, Fetchmail, Mairix, Msmtp, GnuPG, Abook, ELinks, and Mixmaster.
eLyXer (pronounced elixir) is a LyX to HTML converter. While there are a ton of such projects all over the Web, eLyXer has a clear focus on flexibility and elegant output. LyX is a wonderful text editor that produces beautiful PDF files. Internally, it exports documents to LaTeX, and from there to PDF. Sadly there is not an equivalent “export to HTML” option. With eLyXer, you can convert your master’s thesis, learned article, fascinating novel, or love letter to an HTML page that you can then publish on the Web. It is a standalone tool that does not depend on LyX.
Baruwa (Swahili for letter or mail) is a Web 2.0 MailScanner front-end. It provides an easy to use interface for managing a MailScanner installation. It is used to perform operations such as releasing quarantined messages, spam learning, whitelisting and blacklisting addresses, monitoring the health of the services, etc. Baruwa is implemented using Web 2.0 features (AJAX) where deemed fit. Graphing is also implemented on the client side using SVG, Silverlight, or VML. It includes reporting functionality with an easy to use query builder. Results can be displayed as message lists or graphed as colorful and pretty interactive graphs. Custom MailScanner modules are provided to allow for logging of messages to the MySQL database with SQLite as backup and for managing whitelists and blacklists.
Urban Lightscape is a photo filter for exposure correction, localized brightness adjustments, dodging and burning, and the introduction of synthetic lighting to a photo. A simple "double-click-and-drag" paradigm is used to place control points on a photo, and clever edge detection localises and interpolates lightness adjustments around and between these points. Results are rapid, with additional controls for more subtle refinements.
