Central Operations Dashboard

Module: Network Access Control (NAC)

COD-NAC Module - Central Control and Intelligent Access Security

The COD-NAC module (Network Access Control) provides companies with a central, vendor-independent solution for managing and securing their IT infrastructure.

Modern networks today have to securely integrate a wide range of devices, from employee laptops to IoT components to guest smartphones. The COD-NAC module automates these processes while ensuring maximum transparency, flexibility, and control.

Through integration with existing NAC systems such as FreeRADIUS or PacketFence , the module creates a unified control center in the Central Operations Dashboard (COD).

This creates a seamless link between security policies, network access, and centralized monitoring, vendor-independent and scalable to the requirements of your company.

Automatic VLAN-Based Access Control & Segmentation

 "Automated network segmentation. Your devices always end up in the right security zone, with no manual effort."

Event-Driven Assignment & Time-Window Access


"Flexible access control by time, role, and situation, for example guest access, maintenance technicians, or shift operations, all handled automatically."

Vendor-Independent Multi-Vendor Integration


"Keep using your existing hardware. Say goodbye to vendor lock-in. Bring Cisco, Aruba, Allied Telesis, and others together under one central management."

Why use COD - NAC?


Who should use COD - NAC?

​


Midsize companies (SMBs) with a heterogeneous network environment

  • Companies with, for example, multiple locations, many different end devices (employee laptops, guest smartphones, IoT sensors), and often mixed hardware.
  • Especially suitable when existing infrastructure is to be kept in use and vendor lock-in is not wanted.

"You want security and control without having to replace all of your hardware."

Industrial Companies / Manufacturing & OT Environments


  • Manufacturing, factories, and facilities with IT/OT environments; devices such as IoT sensors and controllers, with external maintenance technicians, and so on.
  • Requirements: segmentation of IT/OT, time-based access (e.g., for maintenance), automatic detection of new devices.

"Your network world is complex. We bring order, control, and security so that production runs smoothly."

Educational Institutions, Healthcare, and Public Sector Organizations

  • Organizations with many changing devices and users (students, guests, external service providers, patient and visitor devices).
  • Requirements: guest access, time-window access, compliance and regulations, easy management of large numbers of devices.

"Flexible, secure, and easy to manage, even in highly dynamic environments."

Your Benefits at a Glance

  • Central management: Unified control and monitoring of all network access in a single interface.
  • Extended integration: Compatible with existing NAC systems, with more integrations added on an ongoing basis.
  • Automation & security: Reduces administrative effort and minimizes security risks.
  • Future-proof & flexible: Scalable architecture for growing networks and new technologies.

Continuous Ping Polling

<Proactive Network Monitoring>

The COD NAC module continuously runs automated ping checks to capture the status of all registered network devices in real time. This constant monitoring ensures that inactive, faulty, or unknown clients are identified immediately.

Through these regular checks, the system detects not only dropped connections but also suspicious activity patterns. If a device unexpectedly stops responding or an unknown device appears on the network, IT administrators are notified immediately.

Reduces administrative effort and minimizes security risks.

Regular status checks

Configurable ping intervals for an optimal balance between network load and response time

Immediate anomaly detection

Automatic alerting on status changes or unauthorized devices

Historical analysis

Long-term analyses to identify patterns and optimize network stability

Flexible Time Control

<For Precise Access Authorization>

Time-based access policies give companies the ability to control network access precisely by time criteria. This feature is especially valuable for organizations with changing user groups such as guests, temporary workers, interns, or external service providers.

Compliance benefit: Time-based access control meets key requirements of security standards such as ISO 27001 and supports documentation for compliance audits. 

Guest Access


Temporary network access for visitors during business hours, with automatic deactivation outside defined time windows.

Shift Operations


Access authorization for employees only during their working hours, increasing security in 24/7 operations.

Maintenance Windows


Time-limited access for external service providers, automatically revoked once maintenance work is complete.

Multi-Vendor Support

<Vendor-Independent Flexibility>

One of the most compelling features of the COD NAC module is its independence from individual hardware vendors. In heterogeneous network environments, common in organically grown company structures, this flexibility enables central management without vendor lock-in.

IT departments can keep using their existing hardware infrastructure while benefiting from a unified security policy. This reduces investment costs and makes it easier to modernize the network infrastructure step by step.

 The open architecture of the COD NAC module guarantees that companies are not tied to a single vendor. Future expansions and technology changes can be implemented flexibly, without having to replace the entire access control infrastructure.

Configurable Automatic Client Cleanup


Over time, corporate networks accumulate numerous outdated device entries: decommissioned laptops, replaced smartphones, or temporary test devices. These "digital dead records" clutter the overview and can pose potential security risks.

Automatic client cleanup is based on flexibly configurable criteria such as inactivity duration, last login time, or device status. Administrators can define individual thresholds and set exception rules for specific device classes. This keeps the device database current and well organized at all times.

Interfaces - FreeRADIUS, PacketFence & More

The COD-NAC module acts as an integration layer between your network access control and the central management in the COD (Central Operational Dashboard).

  • FreeRADIUS: use of existing authentication/authorization workflows (802.1X, MAC auth), adoption of attributes (e.g., VLAN, roles), and feedback of status and event data.
  • PacketFence: integration of quarantine/registration flows, guest portals, and policy mechanisms.
  • Cisco ISE, Aruba ClearPass, MACMon: already-established NAC systems can be connected effortlessly. COD NAC uses their data, events, and policy decisions and brings them into your central dashboard.
    The result: a central view & control, without having to replace your existing NAC infrastructure.
