The old castle-and-moat security model is dead. In an era of remote work and cloud-native applications, the perimeter has dissolved. "Zero Trust"—the principle of "never trust, always verify"—is now the gold standard for enterprise security.
Identity as the New Perimeter
Zero Trust relies heavily on strict identity verification for every person and device trying to access resources, regardless of whether they are inside or outside the network. This has fueled growth for Identity and Access Management (IAM) providers and Multi-Factor Authentication (MFA) solutions.
Micro-segmentation
Another key pillar is micro-segmentation, which prevents lateral movement of attackers within a network. If a breach occurs, it is contained to a small zone. Cybersecurity firms specializing in granular network visibility and automated policy enforcement are seeing their order books swell as corporations rush to modernize their security stacks.
