Delivers identity-aware and risk-driven segmentation modeling across IT, OT, IoT, and IoMT environments

Forescout Technologies, a global leader in cybersecurity, today announced a new, agentless, cloud-native network segmentation solution purpose-built for hybrid IT, OT, IoT and IoMT enterprises to visualize and model zones from a single console. These new segmentation capabilities in the Forescout 4D Platform™ provide identity- and attribute-driven zone modeling for managed, unmanaged, and unagentable devices. With no network redesign or vendor lock-in, Forescout reduces onboarding from weeks to hours.

Segmentation is foundational to Universal Zero Trust Network Access (UZTNA), yet most organizations struggle to operationalize it. Traditional models force impossible tradeoffs: workload-only tools don’t cover OT and IoT environments, OT-centric platforms miss IT, and agent-based solutions can’t support unmanaged or agentless devices.

The Forescout 4D Platform takes a visibility-first approach starting with device identification, behavior, and risk assessment, then turns that context into an intuitive, matrix-driven view that helps teams confidently model device communication patterns before enforcing controls. With more than 30 agentless discovery methods consolidated into one platform, Forescout delivers complete device coverage, ensuring organizations can base decisions on the most complete and accurate asset context. This context-driven approach also supports compliance outcomes for mandates such as HIPAA and PCI DSS by enabling more granular, auditable access policies based on asset identity and behavior rather than static network constructs.

“This evolution transforms segmentation from a static, IP-centric project into a continuous, device identity-driven practice that advances UZTNA,” said Paul Kao, Chief Product Officer, Forescout. “By grounding decisions in a device’s identity, attributes, behavior, and risk instead of its network location, we eliminate the fragility of traditional segmentation approaches. Because our architecture starts with visibility and real communication patterns, organizations design smarter, enforce more confidently, and strengthen their UZTNA strategy from day one.”

Key benefits:

• Stronger, more resilient segmentation design. Identity- and attribute-based zone modeling helps customers build segmentation policies that automatically adapt to device type, function, behavior and risk, reducing outages and eliminating fragile IP-based configurations caused by DHCP churn, device mobility, and network changes.
• Real-time visibility into east-west risk. Matrix-driven visualization and UX give customers instant insight into risky communication paths using intuitive heatmaps and ready-to-use zone templates.
• Comprehensive device coverage. Agentless coverage spans IT, OT, IoT, and IoMT, using 30+ discovery methods to help customers confidently discover, classify, and understand the behavior of all devices. No need for agents, replacing infrastructure, or locking into a single vendor.
• Rapid time to value. Cloud-native delivery allows customers to onboard in hours, not weeks, with a plugin-less, API-key setup that accelerates deployment and delivers instant value.

“Segmentation only works when it reflects how environments actually operate,” said Justin Foster, Chief Technology Officer, Forescout. “By anchoring segmentation modeling to device identity and behavior, and delivering it natively in the cloud, the Forescout 4D Platform aligns with how teams design, validate, and govern segmentation at scale, which directly enables UZTNA and CTEM programs. The new capabilities establish the architectural foundation for simulation-first validation, violation-aware enforcement, and AI-driven policy baselines, so customers can see everything first, model with confidence, then enforce with precision and reduce lateral movement risk without disrupting the business.”

As organizations face rapid device growth and rising risk, the need for unified, continuous segmentation is urgent. IoT devices are projected to increase from 18.5 billion in 2024 to 39 billion by 2030, and Forescout Research – Vedere Labs’ 2026 Riskiest Connected Devices Report reveals the rate of change is accelerating sharply, with 75% of the riskiest devices new to the rankings in just the last two years. Forescout alleviates these pressures by containing ransomware blast radius, eliminating blind spots across IT, OT, IoMT and IoT, streamlining segmentation modeling and design, and giving SOC teams clear east-west visibility for faster investigation. The result is safer operations, stronger compliance, and measurable risk reduction.
