Next-Gen NAC and Network Security

Forescout Network Security solutions leverage synergies between network access control, security, and Zero Trust to create a holistic, compliant, and data-centric framework for the business. This approach reduces attack surfaces and aligns with cybersecurity best practices, including highly-regulated industries.

Our next-gen network access control offers a comprehensive, flexible, and non-disruptive approach that provides essential capabilities for enterprises to maintain robust security postures and implement Zero Trust principles effectively.

Unified Cybersecurity Fabric

Forescout’s Network Security Solutions, including Network Access Control, provide unified visibility and control over all network assets, ensuring effective cybersecurity monitoring, threat detection, and incident response. In addition, the solution integrates with IT tools, ticketing systems, and SIEM to deliver coordinated threat responses and automated remediation actions, which support an adaptive approach to Zero Trust.

Agentless Visibility

Comprehensive Device Visibility

Asset discovery and inventory capabilities use active and passive techniques to maintain complete visibility of all IP-connected assets, including IoT/OT devices. The Forescout Device Cloud, with over 12 million device fingerprints, provides high-fidelity device classification, ensuring coverage across all locations and device types without blind spots.

Enforce Secure Network Access

Granular Network Access Control

Forescout ensures least privileged access by dynamically assigning devices to appropriate VLANs or applying access control lists based on predefined policies. Agentless controls enforce these policies without requiring software installations on devices.

Continuous Monitoring

Automated Policy-Based Enforcement

Continuous monitoring and validation of connected devices allow Forescout to dynamically adapt access privileges and automate threat responses based on behavior, posture, or compliance deviations. Non-compliant assets are automatically subjected to the correct security policies.

150+ Classification Attributes

Intelligent Segmentation

These capabilities enhance access control by managing who can access different network parts and when. This function supports the principle of least privilege and helps analyze network traffic from a dynamic zone perspective, informing planning, deployment, and automated policy enforcement. Network segmentation also restricts traffic flows between assets, reducing the potential blast radius of threats.

Forescout Network Security Solutions and Zero Trust

Forescout’s next-gen network access control helps you create a foundation for implementing Zero Trust principles from any starting point to align with business resources and budgets. Forescout Network Security Solutions also integrate with existing IT and security tools, such as Microsoft Azure, ServiceNow, CrowdStrike, and Palo Alto, enabling content sharing, automated workflow orchestration, and comprehensive response measures. This supports the enforcement of Zero Trust principles by ensuring only authenticated, compliant assets access the network.

“The ability to remotely find the infected device and immediately neutralize or quarantine it to keep the network safe has been a game changer. Now we get an alert in our Splunk SIEM and, via Forescout integration, we know details such as whether or not the infected device is critical. If it is critical, it is immediately quarantined; if not, the incident is escalated for review. Our SOC typically responds to a ransomware incident in under 30 minutes, versus four, six, eight hours or more.”

Network Access Control FAQ

What is the difference between traditional NAC and Next-Gen NAC?

  • Traditional NAC systems use trusted approaches like 802.1X protocol, VLAN quarantining, ARP-based control, and port mirroring for access control.
  • Next-gen NAC solutions like Forescout for Network Security are not just security solutions, but comprehensive ones. They deliver complete asset visibility and control across the network, including BYOD and OT/IoT devices without stringent requirements on 802.1x. This level of coverage can provide a sense of security and confidence to network engineers and security teams, who can implement these technologies as part of a robust ecosystem that leverages hundreds of integrations for advanced features and functions across the IT stack.

What compliance standards do Next-Gen NAC solutions such as Forescout Network Security Solutions help meet?

  • National Institute of Standards and Technology Special Publications (NIST SP) includes a set of recommended security and privacy controls for federal information systems and organizations to help meet the Federal Information Security Management Act (FISMA) requirements.
  • Health Insurance Portability and Accountability Act (HIPAA)- modern NAC helps enforce access controls and security policies for protecting sensitive health information.
  • Sarbanes-Oxley (SOX)- modern NAC helps maintain and report on internal controls.
  • Payment Card Industry Data Security Standard (PCI DSS) Modern NAC supports compliance by controlling access to cardholder data environments and enforcing security policies.

How does Forescout for Network Security help me implement Zero Trust?

  • Forescout for Network Security continuously discovers, identifies and maintains accurate asset inventories, enabling classification and assessment that organizations can use to verify the identity and integrity of everything attempting network access. The solution then automatically applies the most granular, least-privilege access controls and security policies. This granularity helps enforce Zero Trust principles by ensuring that only authenticated, compliant assets access the network.

What are the benefits of the Forescout Platform?

  • Every organization is made up of Cyber Assets and Users accessing resources via a network fabric. Regardless of the type of asset, these are systems with Network Interface Cards, MAC addresses, IP addresses, TCP/IP stacks, operating systems and they are providing a service. What that service IS, determines the criticality and role of that asset. Many organizations have established a cyber eco-system of products that communicate through or makeup the network fabric layer to provide security of cyber assets. The function or service that assets provide, and the cyber ecosystem of tools may vary, but there is one constant. Complete security starts with cyber asset awareness and an accurate inventory of ALL assets and where they are.
  • Forescout actively integrates with the network fabric out-of-the-box and passively monitors asset communications to DISCOVER which assets are on the network and where they are. This network integration is a critical step that most vendors overlook. While passive monitoring is quick and simple, it isn’t holistic, won’t discover devices that aren’t communicating through chokepoints, doesn’t scale well, and ultimately won’t address the challenges we’ve discussed.
  • Once Forescout has identified all connected assets, it ASSESSES what they are through a collection of active and passive methods that we will discuss shortly. The information is enriched through Forescout’s Cloud services. The Forescout Cloud consists of billions of datapoints to accurately assess device types, associated risks, and potential threats.
  • Then, Forescout integrates out-of-the-box with your existing cyber ecosystem to enrich these investments by making sure they are configured properly on assets. It also orchestrates sharing of insights and data between investments. Lastly, Forescout takes its collection of assets and insights gained through discover and assess to CONTROL your digital terrain. This comes in the form of workflow automation to remediate assets directly, control access via the network, automate ticketing, automate CMDB updates, and a whole myriad of other 3rd party workflows.
