Microsegmentation directly addresses the challenge of unauthorized lateral movements by dividing IT environments into controllable compartments, enabling adopters to securely isolate workloads from each other while making network protection more granular. As cyber-attackers continue to try new ways to dodge security measures and roam across IT environments, microsegmentation is moving into the mainstream.To read this article in full, please click here READ MORE HERE…

In a March 25 post the firm wrote: “Encouragingly, many of the areas hit hardest by the spread of the coronavirus are holding up to increased network demand. Cities like Los Angeles, Chicago, Brooklyn, and San Francisco have all experienced little or no disruption. New York City,  now the epicenter of the virus in the U.S., has seen a 24% dip out of its previous ten-week range. However, with a new median speed of nearly 52 Mbps, home connections still appear to be holding up overall.”To read this article in full, please click here READ MORE HERE…
