This is a tough time for many of our customers. We’ve been busy helping everyone expand their remote access capabilities to deliver secure apps and desktops to users working from home around the globe. While Citrix has been able to do a good job keeping up with the orders and license fulfillment, and many other vendors have been quick to offer options to help analyze and scale out other aspects of the environment, such as firewalls and VDI infrastructure capacity planning, some vendors haven’t... read more.

Microsoft Windows 7 and Windows Server 2008 reached end of life on January 14, 2020. This means that Microsoft will no longer be releasing free security patches, updates, or support when something goes wrong. Although these operating systems won’t instantly stop working or become security risks overnight, there are risks with staying on these operating systems for an extended period of time. What happens if I stay on these operating systems? There is a huge risk of being exploited by cyber crimina... read more.

Perhaps one of the most popular features of Exchange is the ability to connect Outlook running on a PC to Exchange over the Internet when outside the corporate network without the need to establish a VPN connection.

Many organizations want or need to restrict Outlo... read more.

Microsoft is making WVD very attractive, starting with a unique multi-session version of Windows 10 which is only available in Azure through this offering and continuing with extended support for... read more.

The good news is, it is a very simple fix! Citrix UPD relies on a series of printer drivers to be installed on the VDA machine. When a client printer is mapped into a session, it is automatically mapped to one of these three drivers: The Citrix Universal Printer and Citrix XPS Universal Printer drivers... read more.

One of the most common attack vectors for cloud servers is through Remote Desktop Protocol (RDP) or Secure Shell (SSH).

Hackers are constantly running scans on the IP ranges owned by the cloud providers, and as soon as a... read more.
