Network Access Control System O'smart NAC

O'smart NAC

Proscend Network Access Control System, O'smart NAC, is built on a Zero Trust Architecture, leveraging ARP and IEEE 802.1X mechanisms to enhance internal network protection and device verification. Integrated with Proscend Ethernet Switches, it automatically generates a visualized network topology, enabling real-time visibility into traffic, connection usage, and device compliance across complex, large-scale Layer 2 network deployments. O'smart NAC effectively prevents unauthorized access, IP conflicts, and intrusion risks, safeguarding enterprise operations and critical digital infrastructures with a secure, cost-efficient, and resilient cybersecurity defense.

Advantages

Enhance Zero Trust security for compliant and efficient use of network resources and devices.
Enforce device verification via IP monitoring and strict authentication to prevent data leakage.
Integrate with Proscend network switches to enable visual topology and prevent attacks.
Combine IEEE 802.1X authentication with ARP spoofing blocking to reinforce network access control.
Centralize device history via an event timeline for one-click visibility into connection status, logs, and enforcement actions.

Application

Proscend Network Access Control System, O'smart NAC, addresses the challenges of distributed internal devices and complex network architectures, where device compliance issues and potential threats are difficult to detect in real time. Uncontrolled BYOD usage and unauthorized switches or access points frequently lead to IP conflicts, service disruptions, and security blind spots, preventing administrators from maintaining unified visibility, access control, and compliance governance across the network.

Precision Defense, Connection Visibility

Combined with Proscend Ethernet Switches, O'smart NAC automatically creates a visualized network topology that clearly maps switch information to corresponding ports. With graphical interfaces, it can achieve real-time visibility into connection status and usage, enabling rapid identification of abnormal or unauthorized devices. When risks are detected, the system can immediately isolate affected ports, preventing threat propagation and enabling coordinated, proactive network protection.

Never Trust, Always Verify

O'smart NAC operationalizes Zero Trust with a clear principle: verify before trust. Every device is placed into controlled isolation for identity and compliance validation. Compliant devices are automatically assigned appropriate VLANs, while non-compliant endpoints remain restricted until remediation. This enforces least-privilege access from the edge, delivering a scalable and resilient Zero Trust foundation.
