The Future of Proactive Cyber Defense: Forescout VistaroAI™

Modern Network Security

Forescout Universal Zero Trust Network Access (UZTNA) delivers agentless, continuous access controls for IT, OT, IoT, and IoMT.

Today’s enterprise networks blend traditional IT devices with smart IoT sensors, OT assets, and IoMT devices – all critical to business operations. This expanding device ecosystem creates visibility gaps and increases the attack surface, leaving cyber risks unchecked across managed and unmanaged assets.

Modern threats demand a modern approach that provides continuous visibility, context-aware control, and dynamic enforcement across the entire network. Explore UZTNA with our ebook: Five Steps to Combating Emerging Threats with Network Security.

Where Traditional Network Protection Methods Fall Short

62%

Of organizations don’t have a complete inventory of their IoT/OT devices.1

75%

Of organizations report widening visibility gaps in end-user and IoT assets.2

35%

Of organizations had IoT/OT devices targeted directly or as part of a larger attack.1

Growth in UZTNA adoption is expected by major analysts by 2027

It’s not uncommon for organizations to have multiple asset inventories in their ecosystem of IT and security tools. But even when combined through lengthy manual effort, they rarely cover the entire attack surface due to their limited coverage of managed and unmanaged assets.

Many organizations rely on traditional software agents to monitor and protect the endpoints on their networks, but smart IoT sensors, industrial process controllers, and medical devices can’t support agents, creating blind spots that attackers will exploit.

Waiting on scheduled scans to sweep the network for rogue or at-risk devices allows attackers to infiltrate without being noticed. Some forms of active scanning can even disrupt OT and IoMT devices that monitor or control critical operations causing financial, reputational, and even physical harm.

UZTNA brings continuous, device‑aware access control to modern networks. It authenticates and authorizes both users and devices, managed or agentless, and grants least‑privilege access to only the necessary applications or segments. Policies adapt in real time based on posture and risk, across campus, branch, and remote environments.

What Does Modern
Network Security Look Like?

Compound conditions and actions

Continuous Compliance & Asset Identification

Discover, identify, and continuously assess the security posture of every connected asset—from IT devices to IoT, OT, and IoMT in real-time without installing software agents, and fix missing, broken, or out-of-date security agents among your existing ecosystem of tools.

learn more
Real-Time & Continuous

UZTNA Continuous Risk Assessment

Continuously monitor all connected assets across heterogenous networks for noncompliance or unusual behavior and enforce least privilege access based on continuous risk assessment, ensuring that every device receives only the minimum access required to perform its function.

learn more
Vendor & Device Agnostic

Dynamic Segmentation Management

Visualize traffic flows between groups of assets and design dynamic segmentation policies that enforce least privilege access to shrink the attack surface without impacting your operations.

learn more
manually initiated control actions

Automate Dynamic Access & Cybersecurity Workflows

Continuously evaluate access decisions based on real-time asset context, security posture, and behavior while sharing asset details with your ecosystem of security and management systems to automate workflows across disparate tools, accelerating system-wide response to risks and threats and enabling dynamic access.

The Foundation for a Zero Trust Architecture

A zero trust architecture (ZTA) is a security design approach, not a single-vendor solution. Forescout can help you adopt a NIST SP 800-207-based ZTA within your existing multi-vendor environment, from identifying, monitoring and controlling connected assets to orchestrating enforcement and remediation. Start your zero trust journey without needing to rip and replace your existing infrastructure or security controls.
