Dell’Oro Group forecasts the microsegmentation market will grow at a 21 percent compound annual growth rate (CAGR) from 2025 to 2030, driven by enterprise efforts to limit lateral, east-west movement across hybrid cloud, Kubernetes and private AI environments.
The projection was published in the firm’s May 2026 Hybrid Mesh Firewall and Microsegmentation report, which positions microsegmentation as increasingly tied to AI-era infrastructure and containment requirements.
In the same report, Dell’Oro said Hybrid Mesh Firewall (HMFW) platforms—which it described as focusing on north-south traffic—are expected to reach a 12 percent CAGR over the same five-year period. The company framed HMFW as a “broader fabric” for distributed firewalling alongside more granular microsegmentation controls for workload-to-workload traffic.
“Microsegmentation is moving from a zero-trust best practice to an AI-infrastructure requirement as enterprises create more high-value east-west paths among workloads, data stores, and agentic systems,” said Mauricio Sanchez, Sr. Director, Enterprise Security and Networking at Dell’Oro Group. “HMFW provides the broader fabric for distributed firewalling, but Microsegmentation is where the AI-era containment problem becomes most visible,” added Sanchez.
Dell’Oro said demand is widening from network visibility and mapping into policy enforcement, with organisations seeking least-privilege controls and audit evidence across distributed environments. It also noted that platform convergence could complicate market accounting, as microsegmentation capabilities are increasingly bundled into HMFW platforms or broader security suites, potentially shifting bookings away from standalone microsegmentation revenue even where adoption grows.
