Nagios Core is open source, free and has good documentation but could use a streamlined install process, updated Web interface and better configuration options.

What you need to know to choose among Ubuntu LTS, Oracle Linux, Fedora Server, Red Hat Enterprise Linux and SUSE Enterprise Server
We found all four products to be capable network monitoring tools that performed well in our basic tasks such as checking for host availability and measuring bandwidth usage. Beyond the basics, there were quite a few differences in terms of features, granularity and configuration options.
Platform as a Service is a cloud-based hosting environment for application development designed to provide a full-featured development, staging and production environment without the need for extensive in-house infrastructure.
Five commercial Linux versions feature easy install, solid management tools and cloud integration.
Connecting remotely to network servers is a fact of life for millions of end users. Whether working from a PC or a mobile device, users rely on secure, reliable remote connections to maintain their productivity.
Available since Windows Server 2008 R2, Microsofts DirectAccess server role became fully integrated with the OS in Windows Server 2012. DirectAccess is designed to connect a VPN-type session automatically as soon as a compatible Windows client is connected to the Internet.
Most of the products tested (except Windows Server 2012), use Oracle's Java in one form or another, at least for client access and also in some cases within the management interface. With numerous vulnerabilities recently discovered in Java, leading to guidance from Department of Homeland Security and others to disable it entirely, this raised some questions about usability and possibly even security of the devices tested.
Microsoft, Oracle offer impressive free versions of their commercial offerings, but MariaDB wins our test
Free or open source databases run hundreds of millions of public-facing and private applications worldwide, but how effective is this technology and how do these products compare? For answers, we reviewed six popular free or open source database products: Microsoft SQL Server Express, PostgreSQL, Oracle's MySQL, MariaDB, Apache Derby and Firebird SQL.
Even as social networking continues to gain in popularity, email remains the undisputed workhorse of messaging, far eclipsing all other forms of electronic communication. Email administration can be a costly function, especially for small to midsized organizations, and many administrators are looking for alternatives to enterprise-sized (and priced) commercial products.
Choosing a mail server is never an easy task. Email management itself is a complex endeavor, and this is reflected in the wide variety of tools we choose to create, edit, send, organize and reply to the vast numbers of email messages that crisscross the globe on a daily basis.
With serious data breaches occurring on almost a daily basis, concerns about data protection have skyrocketed. While some experts believe endpoint breaches may no longer comprise the majority of data leaks, the intentional or unintentional release of sensitive data from endpoints within an organization, whether by employees, contractors or guests, remains a serious problem that data loss prevention (DLP) products seek to address.
The Cisco Ironport is an appliance that is deployed into an existing mail infrastructure. All emails are sent to the IronPort and the IronPort is either the last point out (most common configuration) or it can process email and then send it back to the mail server where it is sent out.
We tested multiple common endpoint scenarios, by trying to upload, print, email or otherwise transfer data that should be blocked, quarantined, warned about or simply monitored under the rules and policies we set up. The following specific types of endpoint tests were conducted:
