According to DistroWatch, "EnGarde Secure Linux is a server-oriented open source operating system that provides services like web, DNS and email simply and securely while eliminating the need for time-consuming "hardening" by the user. EnGarde offers integrated intrusion detection, advanced kernel and network security features, and graphical auditing and reporting - all controlled through Guardian Digital WebTool, a simplified browser-based management system." Sometime back Scott Ruecker from LXer interviewed Dave Wreski CEO of Guardian Digital, makers of EnGarde Secure Linux.
What I love about Engarde is its management interface. Guardian Digital WebTool (GD WebTool) is a secure, user-friendly web-based administration utility with which you can administer a Engarde server with a browser and control every aspect of the system.
In the LXer interview Wreski explains how Engarde is different from other Open Source security distros "that bolt-on security" and what it means to be "explicitly designed with security in mind from the outset".
To understand what the differences are, it’s important to recognize that security is often a comprehensive process of engineering and maintenance. Simply adding spamasssassin (for example) to a distribution doesn't make it effective and enterprise capable - not by a long shot. Part of a secure posture requires engineering these multiple applications, in such a way that each one is secure through its use and scalability, in that specific environment.
This is what EnGarde Secure Linux provides, along with our portfolio of secure applications and managed services: A comprehensive and complete solution for all aspects of enterprise network security, in a manageable interface for proxy cache filtering, Content and Policy Enforcement, Anti-Virus, Anti-Spam, Anti-Phishing protection, Web and DNS services, Intrusion Detection and Prevention, secure remote monitoring and more.
Like many specialized (and some non-specialized) Linux distros, EnGarde is available in both community and paid editions. Wreski highlights the differences in the two offerings and I have to admit that the professional version does look more appealing. The other highlight of the distro and my personal favorite is the tons of freely available documentation available on the site. So next time you're out hunting for a secure server, take a look at EnGarde. You might find what you're looking for.
