This ebook challenges seven of the most common misconceptions surrounding modern microsegmentation and explains why it has become a foundational component of enterprise cybersecurity. It demonstrates how microsegmentation complements endpoint detection and response (EDR) by preventing lateral movement after an initial compromise, rather than replacing endpoint security. The guide also addresses myths that segmentation is too difficult to deploy, unnecessary for organizations already using VLANs and firewalls, or too complex to operationalize at scale. Through practical examples and industry research, it highlights how software-defined segmentation improves visibility, automates policy creation, reduces operational complexity, and strengthens ransomware defenses across hybrid, cloud, and on
