Features and Benefits

Ease of Administration

Koozali SME Server software uses a web-based interface to enable easy administration from any web browser anywhere in the world, very securely protected and accessible remotely via SSH or a VPN, based on strict ACL's and firewall settings.

File and Print Sharing

The core of any network environment is easy and simple access to shared files and printers. Koozali SME Server software allows for the easy sharing of files and printers to Windows and Macintosh clients. The "Information Bay" (i-bay) feature provides easy and convenient information storage and retrieval by multiple groups via web, ftp, or file sharing.

Internet Connection

Small business customers are looking for a simple solution that works with different types of connections to the Internet. Koozali SME Server automates the process of connecting to the Internet. Just connect the server and supply your ISP account information. The server solution acts as a gateway for your entire network and requires no additional client software and minimal configuration. Users can immediately start browsing the Web, using email, and access other Internet services.

Email

With the pervasiveness of email, small businesses increasingly need to support email for all their employees. Koozali SME Server provides a secure reliable email server and allows easy creation of individual and group addresses. For greater versatility, it works with any mail client that uses the industry-standard IMAP, POP3, and SMTP protocols. Secure webmail allows users to access the server from a web browser anywhere on the Internet, to send and receive e-mail via an encrypted (128-bit SSL) link.

Antivirus & Antispam

Koozali SME Server comes default with Antivirus and Antispam mechanisms based on well known and industry standard ClamAV Antivirus and SpamAssassin products.To reduce the amount of possible unsolicited mail, Koozali SME Server fully automatically updates Antivirus signatures, and Antispam rules on a daily bases.

Firewall

Security is always a priority when a company starts using the Internet. Koozali SME Server offers a multi-layer architecture, protecting the external interface through packet-filtering and service restriction. It offers selective address or port binding, application-level access control lists, and protects the internal network from any intrusion.

Remote Access

Businesses with remote or branch sites or telecommuting employees require remote access to their email and to other resources on the local network. SME Server provides multiple tools such as webmail access to email using any browser, 128-bit PPTP (for secure client-to-server VPNs) and open secure shell (SSH) to provide encrypted access to the internal network and server resources for administrators.

Directory Services

Companies typically require a central directory of email addresses that all users can access. Koozali SME Server features a robust directory service that can be used by most email clients (including Outlook, Outlook Express, and Netscape Communicator). This feature is implemented using the industry-standard LDAP protocol.

Web Hosting

Small businesses also need a secure and reliable web presence and an intranet to communicate with employees. Koozali SME Server includes the Apache web server, the most commonly used web server of the Internet. The content can be easily edited and updated from desktop clients (including dynamic content). It also supports the use of Secure Sockets Layer (SSL) connections for e-commerce.

Raid

Koozli SME Server software supports software RAID 1, 5 and 6, for security and redundacy of Terabytes of data.

Backup

Koozali SME Server provides flexible backup methods such as USB Disk backup, tape backup or backup to a remote server. Backups can be fully automated and can include both full and incremental backups.

Automatic Updates

Almost all of the packages that Koozali SME Server includes from upstream vendors are included unmodified. The purpose of doing so is to take advantage of the stability that comes from the huge user base that uses these packages, for security, and to allow automatic updates as soon as an update is available from the upstream vendor.

Extensible

The Koozali SME Server architecture explicitly supports developers by making it easy to drop software into place and remove it without needing to modify existing files. Extensions can easily add new features and there are dozens of them freely available. A few popular examples are Nextcloud, Asterisk VOIP PBX, Wordpress, Mediawiki, Zarafa, Roundcube, Sogo, BackupPC and Zoneminder.
