According to their site,
"Zentyal can act as a Gateway, Infrastructure Manager, Unified Threat Manager, Office Server, Unified Communication Server or a combination of them. One single, easy-to-use platform to manage all your network services."This makes it an ideal solution for small/medium sized businesses(SMBs) to deploy in their offices as a single device by relatively non technical individuals. These functionalities are tightly integrated, automating most tasks, avoiding mistakes and saving time for system administrators. Traditionally this kind of functionality would be hobbled together by IT consultants and would run across multiple systems which introduces complexity and stability concerns.
I have deployed earlier eBox incarnations and have been very happy with their design and performance.
Recently, they released a new version further strengthening their product offering. According to the press release that accompanied the release,
Zentyal 2.0 is based on the new Ubuntu 10.4 LTS distribution and this has implied a major change in all the server components. For this reason, Zentyal 2.0 is a new major release. With this change, the users are ensured higher levels of security, functionality and hardware compatibility.
Besides updating the Zentyal base, this version features significant usability, performance and stability improvements. Additionally, it also includes new features. With the goal of providing a Linux server that can be fully configured through a simple graphical interface, software management improvements have taken place and automatic configuration wizards have been introduced.
I'm keen to test it out and will post my results when I get a chance. In the meantime, check it out yourself and let me know what you think!
