Enhancing cybersecurity with Forescout’s agentless segmentation solution

In the evolving landscape of cybersecurity, Forescout Technologies has introduced a cloud-native network segmentation solution designed for hybrid IT, OT, IoT, and IoMT enterprises. This agentless system aims to provide a unified console for visualising and modelling zones, allowing organisations to manage network segmentation without redesigning infrastructure or relying on a single vendor.

Segmentation is a core component of Universal Zero Trust Network Access (UZTNA), but it can be challenging to operationalise. Traditional approaches often have limitations: workload-focused tools may not cover OT and IoT, some platforms restrict visibility, and agent-based methods may not support unmanaged or agentless devices.

Forescout’s 4D Platform aims to address these issues by prioritising device visibility. It identifies devices, assesses behaviour, and evaluates risk, presenting the information in a grid-based interface that allows teams to model communications before applying controls. Using over 30 agentless discovery methods, the platform seeks to provide comprehensive device coverage. Organisations can make decisions based on accurate asset information, supporting compliance with standards such as HIPAA and PCI DSS by creating access policies based on device identity and behaviour.

Key Benefits:

• Resilient Segmentation Design: Identity- and attribute-based zone modelling enables adaptable segmentation strategies, reducing operational disruptions and eliminating fragility from DHCP changes and network modifications.
• Real-Time Visibility: Matrix-driven interfaces provide immediate insights into communication risks using heatmaps and pre-configured zone templates.
• Comprehensive Device Coverage: Covers IT, OT, IoT, and IoMT devices using multiple agentless discovery methods, without requiring infrastructure replacement or vendor lock-in.
• Rapid Deployment: Cloud-native architecture allows onboarding in hours via plugin-less, API-key configuration, delivering value quickly.
