It seems like we’ve been hearing about the virtues of network segmentation for a very very long time. Every month, however, we find ourselves at customer sites where their implementation of the technique is no better than ‘partial’. It’s not a question of failing to understand the goal, or not appreciating the benefits; instead, it’s a problem of bridging the gap between where they are today, and what’s required to implement a thorough and sustainable segmented network in the future. It is, as the saying goes, a bridge too far.
