Forescout

As AI-driven vulnerability discovery and exploitation accelerate attack velocity to machine speed, Forescout is a foundational cyber defense layer that allows organizations to segment and isolate compromised systems, block lateral movement, and automate response across IT, OT, IoT, and IoMT environments. The Forescout Vistaro™ platform, powered by agentic AI and enhanced with Vedere Labs threat intelligence, delivers a Universal Zero Trust Network Access (UZTNA) architecture that integrates seamlessly with 180+ security and IT products. With Forescout Vistaro, organizations get comprehensive inventory and classification of both managed and unmanaged assets, continuous exposure management, and real-time protection including dynamic network segmentation and automated threat response. 

The Forescout Vistaro™ Platform Solution
The rapid expansion of digital infrastructure across IT, OT, IoT, IoMT, and cloud environments has fundamentally transformed the enterprise attack surface — introducing unprecedented scale, complexity, and risk. At the same time, frontier AI is accelerating the speed, precision, and automation of modern cyberattacks, while emerging quantum computing threats are poised to undermine the cryptographic foundations that organizations rely on today. Together, these forces are reshaping how risk must be understood, prioritized, and managed.  

Device growth continues to surge, with IoT alone projected to expand from 14 billion devices in 2023 to 25 billion by 2030. Forescout Vedere Labs Research shows that the enterprise device landscape is becoming much more complex and dangerous, with the average device risk per industry increasing by 15% year-over-year. As the attack surface gets larger, so do blind spots—creating fragmented visibility, duplicated controls, and unresolved conflicts across security and operations teams.  

Whether the priority is cybersecurity, cyber exposure management, regulatory compliance, or operational resilience in critical OT environments, organizations are facing the same fundamental challenges: 

• What is connecting to my network?
• Where are we exposed and at risk?  
• What is getting past existing defenses?
• How do we proactively mitigate and contain threats?  

In highly regulated industries, these challenges are compounded by the need to demonstrate continuous compliance while enforcing Universal Zero Trust Network Access (UZTNA) across all users, devices, and environments. This requires more than point solutions — it demands a unified platform that delivers continuous visibility, contextual risk prioritization, and real-time control across the entire asset landscape, from on-premises to remote to cloud.

The Forescout Vistaro platform is built to address the full spectrum of modern cyber risk —spanning access, exposure, and operational resilience. It brings together continuous visibility, contextual intelligence, and automated control into a unified architecture that operates across IT, OT, IoT, IoMT, and cloud environments.

At its core, the platform delivers three critical outcomes:  

Universal Zero Trust Network Access (UZTNA)
Extend Zero Trust principles across every device, user, and environment — without gaps. The Vistaro platform continuously verifies identity, posture, and behavior to enforce least-privilege access and prevent lateral movement across IT and OT systems. Unlike traditional approaches that focus on managed endpoints, UZTNA applies consistently across all asset types and locations.

Cyber Exposure Management
Continuously identify, prioritize, and reduce risk across the entire attack surface. The Vistaro platform provides real-time visibility into all connected assets and evaluates exposure based on exploitability, business impact, and threat intelligence—enabling organizations to focus remediation efforts where they matter most.

OT Security and Operational Resilience
Protect critical infrastructure and cyber-physical systems without disrupting operations. The platform enables complete visibility, risk management, and threat response across OT, ICS, and CPS environments—helping organizations maintain uptime, ensure safety, and meet regulatory requirements.This same foundation enables Universal Zero Trust Network Access (UZTNA), ensuring that every asset, whether it’s IT, OT, IoT, or IoMT, is continuously verified and granted the least-privileged access based on realtime context. By combining discovery with UZTNA, the Forescout 4D Platform™ enforces adaptive access policies that reduce risk, strengthen compliance, and secure your entire connected ecosystem.

A Unified Platform Approach

These outcomes are powered by a unified set of platform capabilities that operate continuously and in coordination across every environment. Rather than relying on disconnected tools and fragmented workflows, the Vistaro platform brings visibility, risk intelligence, and enforcement together into a single, integrated system—ensuring that insights translate directly into action.

With four cross-cutting capabilities, the platform spans the connected edge to the cloud, providing total visibility and scanning of managed and unmanaged assets: discover, assess, control, govern.

Discover  
Discovery establishes a complete, real-time understanding of the expanded attack surface. The platform continuously identifies, classifies, and monitors every connected asset – managed and unmanaged – across IT, OT, IoT, IoMT, and cloud environments using extensive discovery methods, integrations, and APIs.  It goes beyond visibility by creating deep, contextual intelligence for each asset, tracking lifecycle events and changes over time to support operational continuity and compliance. This foundation integrates with enterprise systems to unify workflows and enables UZTNA by ensuring every asset is continuously verified and governed based on real-time context.  

Assess  
The Vistaro platform continuously evaluates risk across the entire attack surface by correlating asset posture, behavior, vulnerabilities, and compliance data into contextual, business-aware risk scores. It prioritizes exposures based on criticality, exploitability, and threat intelligence—helping teams focus on what matters most. When risks are identified, automated workflows are triggered to accelerate response. Advanced vulnerability intelligence further ensures continuous identification and prioritization of exposures across IT, OT, IoT, and IoMT environments. 

Control 
The Vistaro platform transforms insight into action through real-time, automated enforcement. It applies dynamic policies based on asset identity, posture, and context to contain threats, enforce compliance, and remediate issues across IT, OT, IoT, and cloud environments.  

Capabilities include automated responses such as quarantining devices, blocking traffic, and orchestrating remediation workflows—enabling rapid mitigation as risks emerge.  

Segmentation is a core component, allowing organizations to enforce granular policies that limit lateral movement and reduce the attack surface. Combined with continuous verification and dynamic access control, the platform enforces UZTNA principles at scale without disrupting operations.

Govern
 Governance ensures consistent, scalable policy enforcement and compliance across the enterprise. The Forescout Vistaro™ platform centralizes policy management and provides continuous validation, reporting, and audit-ready evidence.

Granular policy controls, role-based access, and Zero Trust segmentation help reduce attack surface while maintaining operational continuity. Governance becomes a continuous process — aligning security and compliance efforts with evolving risk and regulatory requirements.

Use Case-driven Outcomes

The Forescout Vistaro platform delivers a comprehensive set of security capabilities designed to address the most critical challenges across today’s expanded attack surface. By combining continuous visibility, contextual risk analysis, and realtime control, organizations can secure every connected asset and operational workflow — across IT, OT, IoT, IoMT, and cloud environments.

The company Forescout is also partly located in The Netherlands. In Eindhoven researched is performed around IoT security and vulnerability assessment of IoMT devices for instance.
